Journal articles on the topic 'Health aspects of Feed additive residues'

The feed additive ractopamine, a β-adrenergic agonist, has been approved for use in livestock for nearly 2 decades. Studies of its possible adverse effects in humans have concentrated exclusively on cardiovascular disease and cardiovascular functional disorders in the past. In this article, whether and how ractopamine may affect neurodegeneration, either to promote or to reduce the incidence of Alz­heimer disease, will be discussed based on the recent controversial findings that β-adrenoreceptor activation not only can stimulate Alzheimer-pathogenic amyloid-β accumulation but also are able to enhance hippocampal neurogenesis and ameliorate mouse memory deficits in independent laboratory studies. Furthermore, environmental enrichment has been found to prevent impairment of memory-related hippocampal long-term potentiation and microglia-mediated neuroinflammation induced by amyloid-β. These beneficial effects are achieved mainly through enhanced β-adrenergic signaling and can be imitated by β agonist isoprotenerol. Finally, it has been demonstrated that the β-adrenergic agonist salbutamol could bind directly to tau protein and interfere with the tau filament formation seen in the prodromal phase of Alzheimer disease. These complex but interesting issues lead to contradictory speculations of possible effects of ractopamine residue in meat on Alzheimer disease. Hypotheses derived from this review surely deserve carefully designed laboratory investigations and clinical studies in the future.

Due to the increasing safety concerns about the risk of spreading antibiotic resistance in the environment, and the presence of chemical residues in animal products, using organic acids (OAs) to replace antibiotic in the diet of farm animals has increased considerably in recent years. It has been suggested that OAs could attribute to diverse elements such as antimicrobial activity, decreasing the pH of digesta particularly in the gastrointestinal tract (GIT), slowing feed transit in the GIT to maximize feed digestion and nutrient absorption, inducing enzyme secretion and activity in the small intestine, and providing nutrients to intestinal tissue. It has been reported that OAs mixture might be more effective than individual OAs due to the synergistic effects of different pKa values and have a broad-spectrum activity. In conclusion, this review showed that an OA mixture, which can improve nutrient digestibility and growth performance, modulate intestinal bacterial populations and improve gut health, as well as decreasing gas emission, can be used as alternative to antibiotic growth promoters. However, the results of OA mixtures are not always consistent, and the response to dietary OAs could be affected by the type of OAs, dosage, feed formula, and the age of animals. In this review, we will give an overview of the current use of OAs mixture in swine feed.

There is a need for newer feed additives due to legal prohibition on inclusion of growth promoting antibiotics in livestock diets in several countries due to antimicrobial resistance. In this context, rare earth elements (REE) have gained attention among animal nutritionists as potential growth promoters. Currently, several studies have reported better weight gain, milk production, egg laying capacity and feed conversion efficiency among different breeds of farm animals following supplementation with REE, with however largely inconsistent results. Furthermore, REE supplementation has also shown to improve ruminal fibrolytic and proteolytic activities as well as flavor of meat with negligible residues in edible tissue, however the mechanism behind this action is still unclear. According to existing research, due to their poor absorption and similarity with calcium REE might exert their action locally on gut microbial populations within the gastrointestinal tract (GIT). Moreover, REE have also shown anti-inflammatory, anti-oxidative as well as immune stimulating effects. The present review aims to broaden the knowledge about use of REE as feed additives for livestock and sum up efficacy of REE supplementation on performance and health of animals by comparing the findings. Till date, researches with REE have shown properties that make them a promising, new and safe alternative feed additive but further exploration is recommended to optimize effects and clarify discrepancy of various results before practical proposals can be drafted.

Weaning is considered the “critical window” in the piglet’s life because it is associated with several stress factors, such as loss of contact with the mother and original litter, solid diet, environmental and structural changes, and the establishment of a new hierarchy. During this abrupt period, several events such as reduced feed intake, high morbidity, susceptibility to enteric infections and post-weaning diarrhoea are observed. The nutritional landscape of the piglet gut is modified, which can compromise the maturity of the gastrointestinal system, the stable intestinal microbiome and the active immunity developed as an indicator of intestinal health. However, with increased awareness of feed safety issues and the development of drug-resistant bacteria, the interest in producing pigs without the use of antimicrobial growth promoters (AGP) is increasing, since long-term use and therapeutic doses of AGP can contribute to the reduction of bacterial diversity and increase of inflammatory bowel disease (IBD). Thus, the most widely researched alternatives include the use of feed additives, feeding strategies, nutraceuticals/functional foods and available handling that can reduce the risk of IBD beyond basic nutritional functions. Studies have reported intestinal alkaline phosphatase as a new nutritional therapy associated with intestinal health which may be a “key additive” in the AGP replacement. In this review article, the purpose is to show some current aspects of feed additive research, addressing a concept of the “intestinal health” from different points of view and properties of alkaline phosphatase.

This study determined the presence, levels and co-occurrence of mycotoxins in fish feeds in Kenya. Seventy-eight fish feeds and ingredients were sampled from fish farms and fish feed manufacturing plants and analysed for 40 mycotoxins using high-performance liquid chromatography-high resolution mass spectrometry. Twenty-nine (73%) mycotoxins were identified with 76 (97%) samples testing positive for mycotoxins presence. Mycotoxins with the highest prevalences were enniatin B (91%), deoxynivalenol (76%) and fumonisin B1 (54%) while those with the highest maximum levels were sterigmatocystin (<30.5–3517.1 µg/kg); moniliformin (<218.9–2583.4 µg/kg) and ergotamine (<29.3–1895.6 µg/kg). Mycotoxin co-occurrence was observed in 68 (87%) samples. Correlations were observed between the fumonisins; enniatins B and zearalenone and its metabolites. Fish dietary exposure estimates ranged between <0.16 and 43.38 µg/kg body weight per day. This study shows evidence of mycotoxin presence and co-occurrence in fish feeds and feed ingredients in Kenya. Fish exposure to these levels of mycotoxins over a long period of time may lead to adverse health effects due to their possible additive, synergistic or antagonist toxic effects. Measures to reduce fish feed mycotoxin contamination should be taken to avoid mycotoxicosis in fish and subsequently in humans and animals through residues.

AbstractThe supplementation of livestock rations with herbs containing bioactive components, such as rosmarinic acid (RA), have shown promising results as a natural feed additive in promoting growth, productive and reproductive performance, feed utilization, fertility, anti-oxidant status and immunologic indices. Furthermore, RA reportedly reduces the risks of various animal diseases and mitigates side effects of chemical and synthetic drugs. RA is a natural polyphenol present in several Lamiaceae herbs like Perilla frutescens, and RA is becoming an integral component of animal nutrition as it counters the effect of reactive oxygen species induced in the body as a consequence of different kinds of stressors. Studies have further ascertained the capability of RA to work as an anti-microbial, immunomodulatory, anti-diabetic, anti-allergic, anti-inflammatory, hepato- and renal-protectant agent, as well as to have beneficial effects during skin afflictions. Additionally, RA is favored in meat industries due to enhancing the quality of meat products by reportedly improving shelf-life and imparting desirable flavor. This review describes the beneficial applications and recent findings with RA, including its natural sources, modes of action and various useful applications in safeguarding livestock health as well as important aspects of human health.

Objective: The study developed mushroom stalk residues as feed additives in the broiler diet for improving the growth performance and immunity of broilers as well as to increase the value of mushroom stalk residues.Methods: In total, 300 ROSS 308 broilers were randomly allocated into fifteen pens with five dietary treatments: i) control, basal diet; ii) CMWM, supplemented with 1% <i>Cordyceps militaris</i> waster medium (CM); iii) CMPE, supplemented with 0.5% CM+0.5% <i>Pleurotus eryngii</i> stalk residue (PE); iv) CMPS, supplemented with 0.5% CM+0.5% <i>Pleurotus sajorcaju</i> stalk residue (PS); v) CMFV, supplemented with 0.5% CM+0.5% <i>Fammulina velutipes</i> stalk residue (FV).Results: The chemical analysis results showed that CM extracts, PE extracts, PS extracts, and FV extracts contain functional components such as polysaccharides and phenols and have both 2, 2‐diphenyl‐1‐picryl‐hydrazyl‐hydrate scavenging and Ferrous scavenging capacities. The group CMWM saw increased body weight gain and feed conversion rate and the promotion of jejunum villus growth, but there is no significant difference in the intestinal bacteria phase. Antioxidant genes in the nuclear factor (erythroid-derived 2)-like 2 (Nrf2)- antioxidant responsive element pathway among the groups are significantly higher than that of the control group, especially in group CMWM.Conclusion: The mushroom stalk residues have antioxidant functional components, can improve the intestinal health and body weight gain of chickens, and can activate the antioxidant pathway of Nrf2 to increase the heme oxygenase-1 expression. The treatment with 1% CM was the most promising as a feed additive.

Supplementation of livestock and poultry diets with herbal plants containing bioactive components have shown promising reports as natural feed supplements. These additives are able to promote growth performance and improve feed efficiency, nutrient digestion, antioxidant status, immunological indices, and poultry health. Several studies have used complex herbal formulas with the partial inclusion of licorice. However, the individual use of licorice has been rarely reported. The major problem of the poultry industry is the epidemiological diseases, mainly confined to the respiratory, digestive, and immune systems. Licorice has certain bioactive components such as flavonoids and glycyrrhizin. The roots of this herb contain 1 to 9% glycyrrhizin, which has many pharmacological properties such as antioxidant, antiviral, anti-infective and anti-inflammatory properties. Licorice extracts (LE) have a positive effect on the treatment of high-prevalence diseases such as the immune system, liver, and lung diseases. Studies showed that adding LE to drinking water (0.1, 0.2, or 0.3 g/L) reduced serum total cholesterol (p < 0.05) of broiler chickens. Moreover, LE supplementation in poultry diets plays a significant role in their productive performance by enhancing organ development and stimulating digestion and appetite. Along with its growth-promoting effects, licorice has detoxifying, antioxidant, antimicrobial, anti-inflammatory, and other health benefits in poultry. This review describes the beneficial applications and recent aspects of the Glycyrrhiza glabra (licorice) herb, including its chemical composition and role in safeguarding poultry health.

Propyl-propanethiosulfinate (PTS) is a component of Allium essential oils. This organosulfur molecule can be used as a feed additive to decrease the appearance of bacterial resistances caused by the residues of antibiotics. In previous in vitro genotoxicity studies, contradictory results were reported for PTS. In this work, the in vivo genotoxicity of PTS in male and female rats was assessed for the first time, following OECD (Organisation for Economic Co-operation and Development) guidelines. After oral administration (doses: 5.5, 17.4, and 55.0 mg/kg PTS body weight), a combination of the micronucleus (MN) assay (OECD 474) in bone marrow and the standard and enzyme-modified comet assay (OECD 489) was performed. After necropsy, histopathological studies were also carried out. The results did not show the in vivo genotoxicity of PTS at any doses assayed, revealed by the absence of increased MN, and DNA strand breaks or oxidative DNA damage in the standard and enzyme-modified comet assays. The histopathological study revealed that only the highest dose tested (55.0 mg/kg) in the liver and all dose groups in the stomach presented minimal pathological lesions in the organs studied. Consequently, the present work confirms that PTS is not genotoxic at the doses assayed, and it is a promising natural alternative to synthetic preservatives and antibiotics in animal feed.

Abstract Inulin is widely used as a prebiotic additive in the nutrition of farm animals and pets. This fructooligosaccharide demonstrates a beneficial effect on host health by stimulating the growth and development of commensal bacterial species inhabiting the large intestine. Used for example in the feeding of piglets, inulin greatly enhances their daily body weight gains and also reduces the risk of anemia (Tako et al., 2008). In poultry, in the case of meat breeds, inulin provides better feed utilization, increases the daily gains and the final carcass weight (Ammerman et al., 1988). In laying hens, it positively stimulates the production of eggs (Chen et al., 2005). The addition of prebiotics in the diet of dogs has a positive effect on the concentration of the end products of sugar and protein fermentation in the colon, thus contributing to the health status and good condition of the animal (Flickinger et al., 2003 b; Middelbos et al., 2007). Moreover, inulin beneficially affects the efficiency of the immune system of the organism (including the anticarcinogenic properties) (Kelly-Quagliana et al., 1998), as well as lipids and the cholesterol metabolism by effectively reducing their concentrations in the blood serum (Grela et al., 2014 a). This paper characterizes inulin as a prebiotic additive in the diet of selected species of monogastric animals. In addition, data about the hypolipidemic and immunostimulatory properties of inulin are presented.

Aflatoxin produced by Aspergillus flavus toxigenic strain was selected as a potent and widely distributed hepatotoxin that induces much health and economic hazards in animals and humans. A. flavus was cultivated on rice to produce the aflatoxin used in the present study. It was aimed to study the adverse effects of aflatoxin on some biochemical parameters in serum and liver of ducklings as well as to evaluate the possible protective effects of N.sativa crushed seeds against the adverse effects of this. Total proteins, albumin, globulins, alanine aminotransferase (ALT) (EC 2.6.1.1) and aspartate aminotransferase (AST) (EC 2.6.1.2), cholesterol and triacylglycerols were measured in the serum of the test animal. The levels of hepatic malondialdhyde and glutathione level, glutathione S-transferase (GST) (EC: 2.5.1.18) activity, aflatoxin residues and histopathological changes were also measured. The obtained results suggest that the addition of N. sativa to duckling’s ration has a protective effect against aflatoxicosis. The result concluded that aflatoxin had hepatotoxic effects through decrease of total proteins, albumin, glutathione and glutathione S-transferase. In addition, aflatoxin induced histopathological changes of liver of the test animal and residues of aflatoxin were measured. So, we advice to use N. sativa as a feed additive for controlling aflatoxicosis in poultry farm DOI: http://dx.doi.org/10.3126/njst.v14i2.10419 Nepal Journal of Science and Technology Vol. 14, No. 2 (2013) 81-90

The aim of the present study was to investigate the effects of butyrate as a feed supplement on the expression of insulin signalling proteins as potent regulators of metabolism and growth in Ross 308 broiler chickens fed maize- or wheat-based diets. Both diets were supplemented with non-protected butyrate (1.5 and 3.0 g/kg of diet, respectively) or with protected butyrate (0.2 g/kg of diet); the diet of the control groups was prepared without any additives (control). On day 42 of life, systemic blood samples were drawn for analyses of glucose and insulin concentrations, and tissue samples (liver, gastrocnemius muscle and subcutaneous adipose tissue) were taken for Western blotting examinations. The expression of key insulin signalling proteins (IRβ, PKCζ and mTOR) was assessed by semiquantitative Western blotting from the tissues mentioned. The type of diet had a remarkable influence on the insulin homeostasis of chickens. The wheat-based diet significantly increased IRβ and mTOR expression in the liver as well as mTOR and PKCζ expression in the adipose tissue when compared to animals kept on a maize-based diet. IRβ expression in the liver was stimulated by the lower dose of non-protected butyrate as well, suggesting the potential of butyrate as a feed additive to affect insulin sensitivity. Based on the results obtained, the present study shows new aspects of nutritional factors by comparing the special effects of butyrate as a feed additive and those of the cereal type, presumably in association with dietary non-starch polysaccharide- (NSP-) driven enteric shortchain fatty acid release including butyrate, influencing insulin homeostasis in chickens. As the tissues of chickens have physiologically lower insulin sensitivity compared to mammals, diet-associated induction of the insulin signalling pathway can be of special importance in improving growth and metabolic health.

Antibiotic Growth Promoter (AGP) synthetic as a feed additive can stimulate growth, prevent some health problems, and improve feed efficiency. However, its journey has raised concerns due to adverse effects such as residues and microbial resistance. The use of turmeric flour and betaine as feed additives is expected to substitute the use of AGP Synthetic in improving the performance of pig carcasses and the safety of consumption. This study was aimed to examine the effect of the addition of turmeric flour and different doses of betaine in the ration on the performance of finisher period pigs. The study was conducted experimentally using a completely randomized design with four treatments and five replications. The objects of the study were 20 male and female finisher Landrace pigs with a finisher period with initial body weights of 55-66 kg/head. The study rations used were R0: basal ration, R1: R0 + 0.4% turmeric flour + 0.1% betaine, R2: R0 + 0.4% turmeric flour + 0.15% betaine and R3: R0 + 0.4% turmeric flour + 0.2% betaine. The parameters measured were carcass weight, backfat thickness, and loin eye area. The addition of turmeric flour treatment did not have any significant effects on carcass weight and thickness of the back fat of the pig. The addition of 0.4% turmeric flour and 0.15% betaine in the ration was the best treatment and resulted in a different effect on the loin eye area compared to that of R0, while treatment R1 and R3 had a similar effect on it. The result of the addition of 0.4% turmeric flour and 0.15% betaine resulted in the loin eye area of the finisher pig of 53.4 cm2

The emergence of antibiotic-resistant bacteria in the intestinal microbiota of broiler chickens, and the possibility of antibiotic residues in meat and meat products are seen as a threat to animal and human health. The search for alternatives to conventional drugs, including natural compounds, is an interesting approach to prevent the adverse effects of antibiotics. Therefore, the aim of the present study was to evaluate whether the addition of tannin (as a quebracho extract) in the diet of broiler chickens could be used to replace in-feed antimicrobials and coccidiostatic drugs, to exert positive effects on animal health and performance. The use of tannin in the diet of broiler chicks as an additive (at 0.5% for 1–10-day-old birds; and 1.0% for 11–42-day-old broiler chickens) enhanced their bodyweight, weight gain and daily weight gain on Day 42 of life, compared with the untreated control group (P &lt; 0.05). However, these findings were not observed when tannin was added at 0.5%. Moreover, broiler chickens fed with an extract containing tannins showed higher erythrocyte counts, as well as haemoglobin and haematocrit concentrations than did those in the control group, whereas counts of total leukocytes and lymphocytes were lower (P &lt; 0.05). The use of a diet with tannins did not influence meat quality compared with a diet containing zinc bacitracin and salinomycin, which altered some parameters associated with meat colour. Moreover, the diet with tannins reduced (P &lt; 0.05) the number of oocysts of Eimeria sp. (36-day-old broilers) and the total faecal bacterial counts (42-day-old broilers) compared with the control group. Finally, intestinal histopathology showed that the addition of tannins minimised the degree of lesions (Degree 1) compared with the control group (Degree 3). On the basis of these results, we concluded that the use of quebracho extract containing tannins can be a suitable approach to improve the performance of broiler chickens, replacing in-feed antibiotics and coccidiostatic drugs. The use of tannins did not change meat quality; however, it caused positive effects on the immune system, and exerted potent bactericidal and coccidiostatic properties, reinforcing its use as a replacement for conventional drugs.

Nanoscience and nanotechnology shows immense interest in various areas of research and applications, including biotechnology, biomedical sciences, nanomedicine, and veterinary medicine. Studies and application of nanotechnology was explored very extensively in the human medical field and also studies undertaken in rodents extensively, still either studies or applications in veterinary medicine is not up to the level when compared to applications to human beings. The application in veterinary medicine and animal production is still relatively innovative. Recently, in the era of health care technologies, Veterinary Medicine also entered into a new phase and incredible transformations. Nanotechnology has tremendous and potential influence not only the way we live, but also on the way that we practice veterinary medicine and increase the safety of domestic animals, production, and income to the farmers through use of nanomaterials. The current status and advancements of nanotechnology is being used to enhance the animal growth promotion, and production. To achieve these, nanoparticles are used as alternative antimicrobial agents to overcome the usage alarming rate of antibiotics, detection of pathogenic bacteria, and also nanoparticles being used as drug delivery agents as new drug and vaccine candidates with improved characteristics and performance, diagnostic, therapeutic, feed additive, nutrient delivery, biocidal agents, reproductive aids, and finally to increase the quality of food using various kinds of functionalized nanoparticles, such as liposomes, polymeric nanoparticles, dendrimers, micellar nanoparticles, and metal nanoparticles. It seems that nanotechnology is ideal for veterinary applications in terms of cost and the availability of resources. The main focus of this review is describes some of the important current and future principal aspects of involvement of nanotechnology in Veterinary Medicine. However, we are not intended to cover the entire scenario of Veterinary Medicine, despite this review is to provide a glimpse at potential important targets of nanotechnology in the field of Veterinary Medicine. Considering the strong potential of the interaction between the nanotechnology and Veterinary Medicine, the aim of this review is to provide a concise description of the advances of nanotechnology in Veterinary Medicine, in terms of their potential application of various kinds of nanoparticles, secondly we discussed role of nanomaterials in animal health and production, and finally we discussed conclusion and future perspectives of nanotechnology in veterinary medicine.

Although the production of safe food for human consumption is the primary purpose for animal rearing, the environment and well-being of the animals must also be taken into consideration. Based on microbiological point of view, the production of healthy food from animals involves considering foodborne pathogens, on the one hand and on the other hand, the methods used to fight against germs during breeding. The conventional method to control or prevent bacterial infections in farming is the use antibiotics. However, the banning of these compounds as growth promoters caused many changes in animal breeding and their use has since been limited to the treatment and prevention of bacterial infections. In this function, their importance no longer needs to be demonstrated, but unfortunately, their excessive and abusive use have led to a double problem which can have harmful consequences on consumer health: Resistance to antibiotics and the presence of antibiotic residues in food. The use of probiotics appears to be a suitable alternative to overcome these problems because of their ability to modulate the immune system and intestinal microflora, and further considering their antagonistic role against certain pathogenic bacteria and their ability to play the role of growth factor (sometimes associated with prebiotics) when used as feed additives. This review aims to highlight some of the negative effects of the use of antibiotics in animal rearing as well as emphasize the current knowledge on the use of probiotics as a feed additive, their influence on animal production and their potential utility as an alternative to conventional antibiotics, particularly in poultry, pig, and fish farming.

HighlightsTrends in the uses of Spirulina over different decades were critically examinedFindings from surveyed literature indicated that Spirulina utilization was mainly focused on its food and feed potential before the last 20-30 yearsThe review observed that research focused on the health and pharmaceutical uses, biofertilizer, bioplastic, cosmetic, bioenergy and pollution control applications of Spirulina are trends that sprouted out within the last 20-25 years.The review has successfully compiled numerous uses of Spirulina microalga for easy readership by readers since many studies have been performed on the uses Spirulina but reviews of this type spanning through different beneficial aspects of Spirulina are still scarce. Hence, this review fills such gap. AbstractThere is a need to have a single document that summarises the present day uses of Spirulina. In this review, the research trend on the health and other applications of Spirulina microalga was critically evaluated. In terms of the health uses, antioxidant, antibacterial, and immunostimulant effects of Spirulina were emphasized. Other uses of the microalga discussed include the use of Spirulina for human and animal food, bioenergy, pollution and ecotoxicology control, cosmetics, bioplastics and biofertilizers. Literature search revealed that Spirulina polysaccharides, phycocyanin size and content play a role in antioxidant activity and DNA repair. The double bonds and positions of –COOH and –OH in Spirulina phenol content and γ-linolenic fatty acids (γ-LFA) have antimicrobial activity. Some compounds in Spirulina improve immune, increase survival rate and enhance distribution of proteins like hepcidin and TNF-α in animal models. High protein, vitamins, fatty acids (FAs) and glycoproteins in Spirulina are easily digestible due to its lack of cellulose and can improve human and livestock growth. Spirulina produces biodegradable and non-toxic biodiesel and useful co-products. Absorption of heavy metals by chemisorption occurs in Spirulina. Phycocyanin and β-carotene of Spirulina increase skin health, Spirulina also cause high cell proliferation and aids wound healing. Bioplastics produced from Spirulina are biodegradable, non-toxic with high blends. Biofertilizers from Spirulina have little or no residual risks, adds soil Nitrogen through Spirulina Nitrogen fixation ability. In addition, the survey of published works on Spirulina for the past two decades indicates that more research is been carried out in recent years using Spirulina, especially studies involving its health potentials and those concerned with molecular analysis. In conclusion, Spirulina is an exceptional commodity with numerous applications, and probably, some of its compounds causing those effects are yet to be isolated and that is one area for further research.

The use of Antibiotics Growth Promoters (AGP) was once a reliance for Broiler farms that aim to improve immunity as well as trigger the growth of broiler. It turned out that the use of AGP elicit a variety of very harmful impacts on human’s health, the presence of residues of antibiotics in broiler meat will reduce resistance of humans who consume them to some types of antibiotics even antibiotics that are prepared to handle the case of multi-resistant bacteria, namely the presence of antibiotic residues in broiler meat that will reduce the resistance of humans who consume them. So no longer impervious to some antibiotics even antibiotics that are prepared to handle the case of multi-resistant bacteria. This has become a limiting factor for the community, especially Muslims who are required to consume foods that are not only halal but bring benefits and do not contain harmful substances as admonitions in the Quran and hadith. This reality requires options to solve problems and answer real problems in people's lives wisely and contextually. Although AGP is required by the broiler, but based on many research results have shown that its role can be substituted with the addition of feed additives such as probiotics, enzymes and herbs as feed quality improvement efforts, included the implementation of biosecurity which must be carried out in an integrated manner. Broiler farms that implement good industry management has proved able to guarantee the availability of broiler as a source of animal protein is Safe, Healthy, and Whole Halal (in the Indonesian acronym is ASUH) and has a wide market share. This context be in accordance to the conception of food safety in Islam, food safety from the Islamic normative context namely halal and food safety from the health aspect, namely Thayyib. This paper responds to the issue of food safety which has been a fidgetiness for all stratums of Muslim society, whereas the ASUH food source is one of the fulfilments of the main points of the Maqasid al-Shari'ah or the general objective stipulated in Islamic law, namely to realize goodness, provide benefits and avoid damage to humans.

Abstract Background Ethoxyquin (EQ) is a common antioxidant which is widely used in animal feed. But the supplement of EQ in animal feed may lead to the residues of EQ and its major oxidation products: ethoxyquin quinone imine (EQI) and ethoxyquin dimer (EQDM) in animal tissue. Thus, it would pose potential health hazards to consumers. However, the method for the simultaneous determination of EQ, EQI and EQDM in animal tissues is currently not available, and the accumulation extend of these chemicals in animal tissues after EQ administration remains to be evaluated. Results A gas chromatography-tandem mass spectrometry method was successfully developed for the simultaneous determination of EQ, EQI and EQDM in swine tissues. The quantitative limits of EQ, EQI and EQDM can achieve to 0.5, 5.0 and 5.0 μg/kg in swine tissues, respectively. The spiked-recovery ratios of the three analytes (5–2000 μg/kg) were in the range of 64.7%–100.7% with relative standard deviations below 11.6%. Moreover, the utilization of this method for the analysis of actual swine tissue samples revealed that the application of commercial EQ additive in swine diet would produce the residues of all the three chemicals (EQ, EQI and EQDM) in fat, kidney, liver and muscle. Conclusions The assay accuracy and precision of this GC-MS/MS method can meet the requirement of quantitative analysis. Meanwhile, the safety of EQ as a feed additive should be seriously considered with regard to food safety concerns since the oxidation product of EQ may have potential carcinogenicity.

Introduction The counterculture that arose during the 1960s and 1970s left lasting social and political reverberations in developed nations. This was a time of increasing affluence and liberalisation which opened up remarkable political opportunities for social change. Within this context, an array of new social movements were a vital ingredient of the ferment that saw existing norms challenged and the establishment of new rights for many oppressed groups. An expanding arena of concerns included the environmental damage caused by 200 years of industrial capitalism. This article examines one aspect of a current environment movement in Australia, the anti-Coal Seam Gas (CSG) movement, and the part played by participants. In particular, the focus is upon one action that emerged during the recent Bentley Blockade, which was a regional mobilisation against proposed unconventional gas mining (UGM) near Lismore, NSW. Over the course of the blockade, the conventional ritual of waving at passers-by was transformed into a mechanism for garnering broad community support. Arguably, this was a crucial factor in the eventual outcome. In this case, we contend that the wave, rather than a countercultural artefact being appropriated by the mainstream, represents an everyday behaviour that builds social solidarity, which is subverted to become an effective part of the repertoire of the movement. At a more general level, this article examines how counterculture and mainstream interact via the subversion of “ordinary” citizens and the role of certain cultural understandings for that purpose. We will begin by examining the nature of the counterculture and its relationship to social movements before discussing the character of the anti-CSG movement in general and the Bentley Blockade in particular, using the personal experience of one of the writers. We will then be able to explore our thesis in detail and make some concluding remarks. The Counterculture and Social Movements In this article, we follow Cox’s understanding of the counterculture as a kind of meta-movement within which specific social movements are situated. For Cox (105), the counterculture that flourished during the 1960s and 1970s was an overarching movement in which existing social relations—in particular the family—were rejected by a younger generation, who succeeded in effectively fusing previously separate political and cultural spheres of dissent into one. Cox (103-04) points out that the precondition for such a phenomenon is “free space”—conditions under which counter-hegemonic activity can occur—for example, being liberated from the constraints of working to subsist, something which the unprecedented prosperity of the post WWII years allowed. Hence, in the 1960s and 1970s, as the counterculture emerged, a wave of activism arose in the western world which later came to be referred to as new social movements. These included the civil rights movement, women’s liberation, pacifism and the anti-nuclear and environment movements. The new movements rejected established power and organisational structures and tended, some scholars argued, to cross class lines, basing their claims on non-material issues. Della Porta and Diani claim this wave of movements is characterised by: a critical ideology in relation to modernism and progress; decentralized and participatory organizational structures; defense of interpersonal solidarity against the great bureaucracies; and the reclamation of autonomous spaces, rather than material advantages. (9) This depiction clearly announces the countercultural nature of the new social movements. As Carter (91) avers, these movements attempted to bypass the state and instead mobilise civil society, employing a range of innovative tactics and strategies—the repertoire of action—which may involve breaking laws. It should be noted that over time, some of these movements did shift towards accommodation of existing power structures and became more reformist in nature, to the point of forming political parties in the case of the Greens. However, inasmuch as the counterculture represented a merging of distinctively non-mainstream ways of life with the practice of actively challenging social arrangements at a political level (Cox 18–19; Grossberg 15–18;), the tactic of mobilising civil society to join social movements demonstrates in fact a reverse direction: large numbers of people are transfigured in radical ways by their involvement in social movements. One important principle underlying much of the repertoire of action of these new movements was non-violence. Again, this signals countercultural norms of the period. As Sharp (583–86) wrote at the time, non-violence is crucial in that it denies the aggressor their rationale for violent repression. This principle is founded on the liberal notion, whose legacy goes back to Locke, that the legitimacy of the government rests upon the consent of the governed—that is, the people can withdraw their consent (Locke in Ball & Dagger 92). Ghandi also relied upon this idea when formulating his non-violent approach to conflict, satyagraha (Sharp 83–84). Thus an idea that upholds the modern state is adopted by the counterculture in order to undermine it (the state), again demonstrating an instance of counterflow from the mainstream. Non-violence does not mean non-resistance. In fact, it usually involves non-compliance with a government or other authority and when practised in large numbers, can be very effective, as Ghandi and those in the civil rights movement showed. The result will be either that the government enters into negotiation with the protestors, or they can engage in violence to suppress them, which generally alienates the wider population, leading to a loss of support (Finley & Soifer 104–105). Tarrow (88) makes the important point that the less threatening an action, the harder it is to repress. As a result, democratic states have generally modified their response towards the “strategic weapon of nonviolent protest and even moved towards accommodation and recognition of this tactic as legitimate” (Tarrow 172). Nevertheless, the potential for state violence remains, and the freedom to protest is proscribed by various laws. One of the key figures to emerge from the new social movements that formed an integral part of the counterculture was Bill Moyer, who, in conjunction with colleagues produced a seminal text for theorising and organising social movements (Moyer et al.). Many contemporary social movements have been significantly influenced by Moyer’s Movement Action Plan (MAP), which describes not only key theoretical concepts but is also a practical guide to movement building and achieving aims. Moyer’s model was utilised in training the Northern Rivers community in the anti-CSG movement in conjunction with the non-violent direct action (NVDA) model developed by the North-East Forest Alliance (NEFA) that resisted logging in the forests of north-eastern NSW during the late 1980s and 1990s (Ricketts 138–40). Indeed, the Northern Rivers region of NSW—dubbed the Rainbow Region—is celebrated, as a “‘meeting place’ of countercultures and for the articulation of social and environmental ideals that challenge mainstream practice” (Ward and van Vuuren 63). As Bible (6–7) outlines, the Northern Rivers’ place in countercultural history is cemented by the holding of the Aquarius Festival in Nimbin in 1973 and the consequent decision of many attendees to stay on and settle in the region. They formed new kinds of communities based on an alternative ethics that eschewed a consumerist, individualist agenda in favour of modes of existence that emphasised living in harmony with the environment. The Terania Creek campaign of the late 1970s made the region famous for its environmental activism, when the new settlers resisted the logging of Nightcap National Park using nonviolent methods (Bible 5). It was also instrumental in developing an array of ingenious actions that were used in subsequent campaigns such as the Franklin Dam blockade in Tasmania in the early 1980s (Kelly 116). Indeed, many of these earlier activists were key figures in the anti-CSG movement that has developed in the Rainbow Region over the last few years. The Anti-CSG Movement Despite opposition to other forms of UGM, such as tight sands and shale oil extraction techniques, the term anti-CSG is used here, as it still seems to attract wide recognition. Unconventional gas extraction usually involves a process called fracking, which is the injection at high pressure of water, sand and a number of highly toxic chemicals underground to release the gas that is trapped in rock formations. Among the risks attributed to fracking are contamination of aquifers, air pollution from fugitive emissions and exposure to radioactive particles with resultant threats to human and animal health, as well as an increased risk of earthquakes (Ellsworth; Hand 13; Sovacool 254–260). Additionally, the vast amount of water that is extracted in the fracking process is saline and may contain residues of the fracking chemicals, heavy metals and radioactive matter. This produced water must either be stored or treated (Howarth 273–73; Sovacool 255). Further, there is potential for accidents and incidents and there are many reports—particularly in the United States where the practice is well established—of adverse events such as compressors exploding, leaks and spills, and water from taps catching fire (Sovacool 255–257). Despite an abundance of anecdotal evidence, until recently authorities and academics believed there was not enough “rigorous evidence” to make a definitive judgment of harm to animal and human health as a result of fracking (Mitka 2135). For example, in Australia, the Queensland Government was unable to find a clear link between fracking and health complaints in the Tara gasfield (Thompson 56), even though it is known that there are fugitive emissions from these gasfields (Tait et al. 3099-103). It is within this context that grassroots opposition to UGM began in Australia. The largest and most sustained challenge has come from the Northern Rivers of New South Wales, where a company called Metgasco has been attempting to engage in UGM for a number of years. Stiff community opposition has developed over this time, with activists training, co-ordinating and organising using the principles of Moyer’s MAP and NEFA’s NVDA. Numerous community and affinity groups opposing UGM sprang up including the Lock the Gate Alliance (LTG), a grassroots organisation opposing coal and gas mining, which formed in 2010 (Lock the Gate Alliance online). The movement put up sustained resistance to Metgasco’s attempts to establish wells at Glenugie, near Grafton and Doubtful Creek, near Kyogle in 2012 and 2013, despite the use of a substantial police presence at both locations. In the event, neither site was used for production despite exploratory wells being sunk (ABC News; Dobney). Metgasco announced it would be withdrawing its operations following new Federal and State government regulations at the time of the Doubtful Creek blockade. However it returned to the fray with a formal announcement in February 2014 (Metgasco), that it would drill at Bentley, 12 kilometres west of Lismore. It was widely believed this would occur with a view to production on an industrial scale should initial exploration prove fruitful. The Bentley Blockade It was known well before the formal announcement that Metgasco planned to drill at Bentley and community actions such as flash mobs, media releases and planning meetings were part of the build-up to direct action at the site. One of the authors of this article was actively involved in the movement and participated in a variety of these actions. By the end of January 2014 it was decided to hold an ongoing vigil at the site, which was still entirely undeveloped. Participants, including one author, volunteered for four-hour shifts which began at 5 a.m. each day and before long, were lasting into the night. The purpose of a vigil is to bear witness, maintain a presence and express a point of view. It thus accords well with the principle of non-violence. Eventually the site mushroomed into a tent village with three gates being blockaded. The main gate, Gate A, sprouted a variety of poles, tripods and other installations together with colourful tents and shelters, peopled by protesters on a 24-hour basis. The vigils persisted on all three gates for the duration of the blockade. As the number of blockaders swelled, popular support grew, lending weight to the notion that countercultural ideas and practices were spreading throughout the community. In response, Metgasco called on the State Government to provide police to coincide with the arrival of equipment. It was rumoured that 200 police would be drafted to defend the site in late April. When alerts were sent out to the community warning of imminent police action, an estimated crowd of 2000 people attended in the early hours of the morning and the police called off their operation (Feliu). As the weeks wore on, training was stepped up, attendees were educated in non-violent resistance and protestors willing to act as police liaison persons were placed on a rotating roster. In May, the State Government was preparing to send up to 800 police and the Riot Squad to break the blockade (NSW Hansard in Buckingham). Local farmers (now a part of the movement) and activist leaders had gone to Sydney in an effort to find a political solution in order to avoid what threatened to be a clash that would involve police violence. A confluence of events, such as: the sudden resignation of the Premier; revelations via the Independent Commission against Corruption about nefarious dealings and undue influence of the coal industry upon the government; a radio interview with locals by a popular broadcaster in Sydney; and the reputed hesitation of the police themselves in engaging with a group of possibly 7,000 to 10,000 protestors, resulted in the Office for Coal Seam Gas suspending Metgasco’s drilling licence on 15 May (NSW Department of Resources & Energy). The grounds were that the company had not adequately fulfilled its obligations to consult with the community. At the date of writing, the suspension still holds. The Wave The repertoire of contention at the Bentley Blockade was expansive, comprising most of the standard actions and strategies developed in earlier environmental struggles. These included direct blocking tactics in addition to the use of more carnivalesque actions like music and theatre, as well as the use of various media to reach a broader public. Non-violence was at the core of all actions, but we would tentatively suggest that Bentley may have provided a novel addition to the repertoire, stemming originally from the vigil, which brought the first protestors to the site. At the beginning of the vigil, which was initially held near the entrance to the proposed drilling site atop a cutting, occupants of passing vehicles below would demonstrate their support by sounding their horns and/or waving to the vigil-keepers, who at first were few in number. There was a precedent for this behaviour in the campaign leading up to the blockade. Activist groups such as the Knitting Nannas against Gas had encouraged vehicles to show support by sounding their horns. So when the motorists tooted spontaneously at Bentley, we waved back. Occupants of other vehicles would show disapproval by means of rude gestures and/or yelling and we would wave to them as well. After some weeks, as a presence began to be established at the site, it became routine for vigil keepers to smile and wave at all passing vehicles. This often elicited a positive response. After the first mass call-out discussed above, a number of us migrated to another gate, where numbers were much sparser and there was a perceived need for a greater presence. At this point, the participating writer had begun to act as a police liaison person, but the practice of waving routinely was continued. Those protecting this gate usually included protestors ready to block access, the police liaison person, a legal observer, vigil-keepers and a passing parade of visitors. Because this location was directly on the road, it was possible to see the drivers of vehicles and make eye contact more easily. Certain vehicles became familiar, passing at regular times, on the way to work or school, for example. As time passed, most of those protecting the gate also joined the waving ritual to the point where it became like a game to try to prise a signal of acknowledgement from the passing motorists, or even to win over a disapprover. Police vehicles, some of which passed at set intervals, were included in this game. Mostly they waved cheerfully. There were some we never managed to win over, but waving and making direct eye contact with regular motorists over time created a sense of community and an acknowledgement of the work we were doing, as they increasingly responded in kind. Motorists could hardly feel threatened when they encountered smiling, waving protestors. By including the disapprovers, we acted inclusively and our determined good humour seemed to de-escalate demonstrated hostility. Locals who did not want drilling to go ahead but who were nevertheless unwilling to join a direct action were thus able to participate in the resistance in a way that may have felt safe for them. Some of them even stopped and visited the site, voicing their support. Standing on the side of the road and waving to passers-by may seem peripheral to the “real” action, even trivial. But we would argue it is a valuable adjunct to a blockade (which is situated near a road) when one of the strategies of the overall campaign is to win popular backing. Hence waving, whilst not a completely new part of the repertoire, constitutes what Tilly (41–45) would call innovation at the margins, something he asserts is necessary to maintain the effectiveness and vitality of contentious action. In this case, it is arguable that the sheer size of community support probably helped to concentrate the minds of the state government politicians in Sydney, particularly as they contemplated initiating a massive, taxpayer-funded police action against the people for the benefit of a commercial operation. Waving is a symbolic gesture indicating acknowledgement and goodwill. It fits well within a repertoire based on the principle of non-violence. Moreover, it is a conventional social norm and everyday behaviour that is so innocuous that it is difficult to see how it could be suppressed by police or other authorities. Therein lies its subversiveness. For in communicating our common humanity in a spirit of friendliness, we drew attention to the fact that we were without rancour and tacitly invited others to join us and to explore our concerns. In this way, the counterculture drew upon a mainstream custom to develop and extend upon a new form of dissent. This constitutes a reversal of the more usual phenomenon of countercultural artefacts—such as “hippie clothing”—being appropriated or co-opted by the prevailing culture (see Reading). But it also fits with the more general phenomenon that we have argued was occurring; that of enticing ordinary residents into joining together in countercultural activity, via the pathway of a social movement. Conclusion The anti-CSG movement in the Northern Rivers was developed and organised by countercultural participants of previous contentious challenges. It was highly effective in building popular support whilst at the same time forging a loose coalition of various activist groups. We have surveyed one practice—the wave—that evolved out of mainstream culture over the course of the Bentley Blockade and suggested it may come to be seen as part of the repertoire of actions that can be beneficially employed under suitable conditions. Waving to passers-by invites them to become part of the movement in a non-threatening and inclusive way. It thus envelops supporters and non-supporters alike, and its very innocuousness makes it difficult to suppress. We have argued that this instance can be referenced to a similar reverse movement at a broader level—that of co-opting liberal notions and involving the general populace in new practices and activities that undermine the status quo. The ability of the counterculture in general and environment movements in particular to innovate in the quest to challenge and change what it perceives as damaging or unethical practices demonstrates its ingenuity and spirit. This movement is testament to its dynamic nature. References ABC News.

Data becomes something of a mirror in which people see themselves reflected. (Sorapure 270)In a 2014 essay for The New Yorker, the humourist David Sedaris recounts an obsession spurred by the purchase of a Fitbit, a wearable activity-tracker that sends a celebratory “tingle” to his wrist every 10, 000 steps. He starts “stepping out” modestly but is soon working hard, steadily improving on the manufacturer’s recommended baseline. “But why?” asks Sedaris’ partner Hugh: “Why isn’t twelve thousand enough?” “Because,” I told him, “my Fitbit thinks I can do better” (n.p.).The record of daily, incidental activity that the Fitbit collects and visualises is important to Sedaris as a record of his (increasing) bodily fitness but it is also evidence in another way, a testament to virtue and a correlate of self-improvement: “The tingle feels so good,” Sedaris says, “not just as a sensation but also as a mark of accomplishment” (n.p.). Improvement is presented as both traceable and quantifiable; data and self are inextricably, though also ironically, linked. With his Fitbit, Sedaris accesses new and precise degrees of bodily information and he connects himself to a visible community of wearers. At first, Sedaris is smug and optimistic; by the time he begins “rambling” compulsively, however, and achieving his “first sixty-thousand-step day,” he has also had an epiphany: “I staggered home with my flashlight knowing that I’d advance to sixty-five thousand, and that there will be no end to it until my feet snap off at the ankles. Then it’ll just be my jagged bones stabbing into the soft ground” (n.p.). When the device finally “dies,” Sedaris experiences an immediate feeling of freedom; within five hours he has “ordered a replacement, express delivery” (n.p.).In their book Self-Tracking, Gina Neff and Dawn Nafus note that both digital technology and a turn to biomedicalisation in the broader culture have amplified the capacity and reach of quantification practices in everyday life. Wearable activity trackers, of which the Fitbit is arguably the most iconic, offer individuals the ability to track minute or previously imperceptible permutations of bodily sensation within an everyday and non-medical context. It is a technological capacity, however, thoroughly embedded in a mobilising rhetoric of “health,” a term which itself has “become a loaded word, not merely a description of a bodily state but also a euphemism for what the speaker believes is desirable” (Neff and Nafus 19). The Fitbit measures movement, but it also signals something about the wearer’s identity that is framed, in the device’s marketing at least, in positive and desirable terms as an indication of character, as a highly desirable aspect of self.In a recent discussion of new forms of online life writing, Madeline Sorapure argues that acts of interpretation and representation in relation to biometric data are “something very similar to autobiographical practice. As in autobiography, subject and object, measurer and measured, are collapsed” (270). In its capacity to track and document over time and its affective role in forming a particular experience of self, the Fitbit bears a formal resemblance to autobiographical practice and specifically to modes of serial self-representation like diaries, journals, or almanacs. The discursive context is crucial here too. Early self-trackers use the pre-formatted almanac diary or calendar to better organise their time and to account for expenditure or gain. The pocket calendar was an innovation that had mass-market appeal and its rapid circulation in the early twentieth century directly shaped diary and account-keeping habits amongst historical populations, and to this day (McCarthy). Such forms are not simply passive repositories but bear cultural ideology. As popular templates for practices of accounting, self-documentation, and affecting, pocket calendars shape what content an individual across their individual day or week is coaxed to attend to or record, and effects what might then be relegated “marginal” or less consequential in relation.How do the technological affordances of the Fitbit similarly coax and shape self-knowledge or ideas of value and worth in relation to personal experience? What kinds of formal and discursive and resonance might there be drawn between wearable personal devices like the Fitbit and historical forms of tracking self-experience, like the diary? Is a Fitbit a diary? In this discussion, I consider pre-formatted diaries, like the almanac or pocket calendar, as discursive and technological precursors or adjuncts to wearable personal trackers like the Fitbit and I explore some assertions around the kinds of subject that digital forms and modes of self-tracking and personal data might then seem to coax or imagine.Tracking SelvesSelf-tracking is a human activity, one far more interesting than the gadgets that have made it easier and far more widespread. (Neff and Nafus 2)In 1726, at the age of 20, the inventor and polymath Benjamin Franklin recorded in his journal the inception of a plan to improve his character. In a chart created to track goals of virtue and progress in character, “black marks” are literal and symbolic, denoting when he has failed to live up to his expectations—two black marks represent a particularly bad effort (Rettberg 438). At age 79, Franklin was still tracking his progress when he wrote about the project in his Autobiography:It was about this time I conceived the bold and arduous project of arriving at moral perfection. I wished to live without committing any fault at any time; I would conquer all that either natural inclination, custom, or company might lead me into. (89)Franklin’s desire to document and chronicle the self-conscious development of his character drives his interest in the form. He was as an almanac devotee and an innovative publisher of the form, which gained immense popularity at this time. Franklin added blank pages to the almanacs he helped produce in the mid eighteenth century and this addition expanded the possibilities for the kinds of data that might be recorded, particularly personal and anecdotal material. The innovation also earned the publishers a good deal more money (McCarthy 49). The mass production of printed almanacs thus had a profound effect on how individuals engaged in various kinds of daily and temporal and social regulation and documentation, including of the self:At the same time as it kept readers aware of the outside world, the almanac could also direct them to the state of their own being. Almanacs were all about regulation, inside and out. Almanacs displayed a regulated universe governed by the laws of planetary motion, by the church calendar, by the zodiac. It seemed natural, then, that some readers might turn to an almanac to regulate themselves. What better way to do that than in a text that already possessed its own system? All one had to do was insert one’s own data in that printed form, like connecting the dots. (McCarthy 53)Mass-market forms that engender habits of accounting are also cultural templates: pre-formatted journals are systems for private documentation that reflect broader cultural and social ideologies. Rebecca Connor observes that historical gender assumptions in relation to time “well-spent” are frequently visible in eighteenth-century mass-market journals explicitly aimed at women, which tended to allocate more space for “social” engagements versus, for example, financial accounting (18).In the twenty-first century, technologies like the Fitbit promise access to data in relation to personal experience but they also reveal dominant cultural and social attitudes to bodies and selves. Deborah Lupton argues that self-tracking as a phenomenon is essentially connected to specific ideological imperatives: “Underlying many accounts of self-tracking is a barely hidden discourse of morality, which takes the form of championing those who take action to improve themselves” (74). Within these influential discourses, acts of self-tracking, no less than Franklin’s virtue chart, acquire significance as moral activities and as the outward sign of good character.Neither self-tracking nor the ideology of virtue that underwrites it are new phenomena. In their cultural study of weight measurement devices, Kate Crawford, Jessa Lingl, and Tero Karpii have explored how both weight scales and wearable devices “emphasize self-knowledge and control through external measurements” (479). Similarly, Lupton has noted that, the “metrics” generated by personal self-tracking devices are “invested with significance” because “data visualisation” is “viewed as more credible and accurate by participants than the ‘subjective’ assessments of their bodily sensations” ("Personal Data" 345).In various historical cultures, objectivity about one’s self is seen as a desire (if not a fact) in relation to conscious self-examination; externalisation, through written or oral confession, is both a virtue and a discipline. While diary writing is, particularly in popular culture, often derided as an overly subjective and narcissistic mode, the diary is also framed within contexts of therapy, or spiritual development, as a possible methodology for self-improvement. For Puritans, though, the act was also understood to entail risks; recording one’s thoughts into a written journal could enable the individual to see patterns or faults in everyday behaviour, and so to identify and rectify habits of mind holding back personal spiritual development. In the twentieth century, “how-to write a diary” self-help guidebooks remediate the discourse of self-knowledge as self-improvement, and promised to refine the method, advising adherents on the kinds of writing practices that might best circumvent problems of individual bias or subjectivity (a claim of an ever-more objective methodology that reverberates to the current moment). Invariably, the more “unconscious” the diary writing practice, the greater the assumed potential for “objective” knowledge (Cardell 34).Contemporary practices of self-tracking extend the prioritisation of external, objective measurement in relation to documenting personal experience. Crawford, Lingel, and Karppi observe that “the discourse around wearable devices gives the impression of radical new technology offering precise and unambiguous physical assessment: devices that reflect back the ‘real’ state of the body” (480). The technology, of course, is not new but it is “improved.” The ideal of a better, more accurate (because externalised and so auditable by the community) self-knowledge sought by Puritans in their journals, or by Benjamin Franklin in his charts and almanacs, resurfaces in the contemporary context, in which wearables like the Fitbit assume powerful discursive status in relation to ideals of truth and objectivity and where the individual is decentred from the position of as “the most authoritative source of data about themselves” (Crawford, Lingel, and Karppi 479).Data SelvesWhat kind of selves do people develop in relation to the technology they use to record or visualise their experience? “There is no doubt,” writes Jill Walker Rettberg, in Seeing Our Selves through Technology, “that people develop ‘affective ties’ to the data they track, just as diaries, blogs, photo albums and other material archives are meaningful to those who keep them” (87). That the data is numerical, or digital, does not lessen this connection:Apps which allow us to see our data allow us to see ourselves. We look at our data doubles as we gazed into the mirror as teenagers wondering who we were and who we might be. We look at our data in much the same way as you might flick through your selfies to find the one that shows you the way you want to be seen. (Rettberg 87)Crucially, Rettberg sees data as both affective and agential and she observes that data can also be edited and shaped by the individual. Some of this practice is deliberate, taking the form of an engagement with narrative as a “story” of self that underpins the practice of writing autobiography, for example. However, the representation of self can also be more oblique. “The first writing” says Rettberg, “was developed not to record words and sentences but to keep accounts. Arguably, recording quantities of grain or other valuables can be a form of self-representation, or at least representation of what belongs to the self” (10).Like log-books or field notebooks, like calendars or almanacs—prosaic forms of daily sequential recording that are understood to prioritise information capture over self-reflection—the Fitbit is usually presented as a method for accruing and representing personal data. In contemporary digital culture, “data” is a complex and fraught term and recent debates around “big data,” which describes the capacity of machines to make connections and perform calculations that a human might not necessarily notice or be able to perform, has crystallised this. What Melissa Gregg calls the power and “spectacle” of data is an ideological pivot in digital cultures of the twenty-first century, one that turns in conjunction to discourses of evidence and authority that emerge in relation to the visual: “sharing the same root as ‘evidence,’ vision is the word that aligns truth and knowledge in different historical moments” (3).For autobiography scholars exploring how formal modes of capture might also be genres, or how a Fitbit might coax a narrative of self, these questions are formative. Sorapure says: Information graphics that visually represent personal data; collaboratively constructed and template-based self-representations in social media and networking sites; the non-narrative nature of aggregated life writing: in these and other new practices we see selves emerging and being represented through interactions with technologies. (271)In the twenty-first century, self-quantification and tracking technologies like the Fitbit are ever more present in individual spheres of everyday activity. These devices prompt behaviour, affect self-knowledge, and signal identity: I am a fit person, or trying to be, or was. A Fitbit cannot record how it feels to spend 34 minutes in the “peak zone,” but it can prompt recollection, it is a mnemonic, and it provides an account of time spent, how, and by whom. Is a Fitbit a diary? The diary in the twenty-first century is already vastly different to many of its formal historical counterparts, yet there are discursive resonances. The Fitbit is a diary if we think of a diary as a chronological record of data, which it can be. However, contemporary uses of the diary, just like their historical antecedents, are also far more diverse and complex than this.Crucially, the Fitbit, like the diary, signals identity in relation to experience and so it reflects various and shifting cultural values or anxieties over what is worth measuring or documenting, and conversely, over what is not. “The private diary,” as Lejeune asserts, is a way of life: “the text itself is a mere by-product, a residue” (31). Historical diary keeping practices unfold from and emerge within cultures that position self-expression and its documentation of this as a means to self-improvement. Seeing the Fitbit within this tradition draws attention to the discursive ideology behind self-tracking as a personal practice that nonetheless positions itself in relation to cultural norms and to ideals (such as health, or fitness, or conscientiousness, or goodness).ConclusionWhat kind of self-representation is produced by practices of self-quantification, where personal data is amassed continuously and contiguously to individual experience? The legacy of centuries of historical diary-practice has been evident to various scholars exploring the cultures of self-tracking that are evolving in response to wearable technologies like the Fitbit. In her book length study of self-tracking cultures, The Quantified Self, Lupton observes that “self-tracking tools” are inevitably “biographical and personal” and that “contemporary self-tracking tools and records are the latter-day versions of the paper diary or journal, photo album, keepsake and memento box or personal dossier” (73). While, in Self-Tracking, Neff and Nafus argue that new technologies “intersect with the way that people have self-tracked for centuries like keeping diaries or logs. The growth of these digital traces raises new questions about this old practice” (2).What does it mean to think of wearable technology like Fitbits in relation to diaries, and what are the implications of such a conception? Privacy settings allow the Fitbit to comply with popular stereotypes of diaries that exist in popular culture; that is, as a locked or secret record. However, in the case of wearable technology the content is in the form of data. While data often poses as neutral and objective information, seeing this instead as diaristic can draw valuable attention to dominant cultural ideals that shape value in relation to self and technology in the twenty-first century. Crucially, “while self-knowledge may be the rhetoric of wearable device advertising, it is just as much a technology of being known by others” (Crawford, Lingel, and Karppi 493-494).Is my Fitbit a diary? It tracks my body’s movements and gestures and reports them to the conscious self. It stores chronologically accumulated data over time. It enables self-reflection and the visualisation of a set of daily habits, and it may produce or coax new behaviour. Diaries have long performed this function: tracking, recording and, documenting for making sense of later, on reflection, or after enough time has passed. Contemporary advances in technology related to self-tracking and personal data collection make possible a new range of previously unimaginable information in relation to individual experience. However, the diary’s cultural status as a “confessional” form intersects with exigencies around “health” and “self-improvement” that corporations producing devices like Fitbit promote to their customers in ways that will demand further attention.ReferencesCardell, Kylie.
