Scott, J. F., J. M. Scott, and O. J. Cacho. "Whole-farm returns show true profitability of three different livestock management systems." Animal Production Science 53, no. 8 (2013): 780. http://dx.doi.org/10.1071/an11248.
Full textAbstract:
On the New South Wales Northern Tablelands, sheep, wool and beef cattle production account for most agricultural output. The industries have been challenged in recent years by environmental and economic factors and are therefore looking for modified or alternative livestock management systems that are capable of sustaining profitability. The Cicerone Project aimed to address these issues by comparing three different grazing and pasture improvement systems. Some recent livestock industry analyses have been based on gross margins which do not include overhead costs. This is an important limitation; economic analysis needs to report key whole-farm business performance measures since overhead costs can differ significantly between livestock management systems. A representative farm approach was used to compare the profitability of the three different livestock management systems. Commercial-scale whole-farm and cash flow analyses over a 5-year period were used to evaluate profitability. No particular system could be recommended to graziers because the test period was not sufficiently representative of the long-term climate to make an adequate assessment about their long-term profitability. Nevertheless, it is apparent that whole-farm level budgets are essential for comparing the overall profitability of different livestock management systems. It is concluded that analysts, consultants and graziers should use whole-farm and cash flow analyses to gauge profitability of different livestock management systems particularly where sustainability issues are important.

Angiosperms diversification was primarily driven by pollinator agents, but non-pollinator agents also promoted floral evolution.Gentiana luteashows pollinator driven flower color variation in NW Spain. We test whether insect herbivores and livestock, which frequently feed inG.lutea, play a role inG. luteaflower color variation, by answering the following questions: (i) Do insect herbivores and grazing livestock show flower color preferences when feeding onG. lutea? (ii) Do mutualists (pollinators) and antagonists (seed predators, insect herbivores and livestock) jointly affectG. luteareproductive success? Insect herbivores fed more often on yellow flowering individuals but they did not affect seed production, whereas livestock affected seed production but did not show clear color preferences. Our data indicate that flower color variation ofG. luteais not affected by insect herbivores or grazing livestock.

Full textAbstract:
ABSTRACTThis paper deals with the gender aspects of urban livestock keeping in Eldoret, Kenya. It shows that men and women play different but complementary roles in livestock keeping. Men show greater preference for and are more involved – in terms of decision-making and responsibility taking – with large livestock and where income is the primary motive for livestock keeping, and perform tasks of an outdoor nature and/or which require considerable technical knowledge. On the other hand, women prefer and exercise greater control over small livestock, make the most decisions about consumption use of livestock products, and perform home-based routine tasks. However, there are instances where men and women cross gender boundaries, for instance where labour of the opposite gender is absent in the household, or as a strategy to control benefits accruing to the livestock. In terms of livelihood outcomes, women's role in livestock keeping is geared more towards improving household nutritional and food security status, while men's role is motivated more by personal benefits.

Full textAbstract:
Purpose: This study examined the effects of climate variability on livestock production in Kenya.Methodology: The study used the Ricardian cross-sectional approach to measure the relationship between climate variability and net revenue from livestock. Net livestock revenue is regressed against various climate and socio-economic variables to help determine the factors that influence variability in net livestock revenues. This study is based on data from ASDSP household baseline survey of 1871 livestock farming households interviewed across the country.Results: The empirical results show that climatic variables (temperature and precipitation) have significant effects on net livestock revenues in Kenya. The net livestock revenues are affected negatively by increases in temperature and rainfall. Unique contribution to theory, practice and policy: The study recommends that there is a need to provide adequate extension information services to ensure that farmers receive up-to-date information so as to ensure increased production. Similarly, policies that increase farmer training and access to credit can help improve net livestock revenues.

"Preliminary Analysis of the Diet of Triturus carnifex and Pollution in Mountain Karst Ponds in Central Apennines." Water 12, no. 1 (December 20, 2019): 44. http://dx.doi.org/10.3390/w12010044.
Full textAbstract:
Mountain karst ponds are sensitive environments, hosting complex trophic networks where amphibians play a major role, often as top predators. The diet of the Italian crested newt (Triturus carnifex) is still poorly known for populations occupying mountain karst ponds. These are traditionally used as livestock’s watering points, leading to water pollution due to excreta and wading behavior. The aim of this paper is to understand the relationship between T. carnifex diet composition, assessed through the stomach flushing technique, and physical and chemical characteristics in mountain ponds, focusing on parameters altered by livestock pressure, such as ammonium concentration and dissolved oxygen. The high diversity of prey items found within the newts’ gut contents confirms the generalist diet even in mountain ponds. The number of prey taxa, their relative abundance and Shannon–Wiener diversity index show variations among the sampled sites, related to livestock organic pollution. Moreover, we report the very first European records of microplastic items in amphibians’ stomach content, which also represent the first evidence for Caudata worldwide. Our findings suggest that livestock pressure directly influences T. carnifex diet and highlight that the emerging issue of plastics is a threat even in remote high-altitude environments.

Full textAbstract:
This study uses data from a mixed-methods survey of livestock-rearing communities in three districts in the Southern Province of Zambia to understand trends in livestock numbers and smallholder farmers' perceptions about their impacts on livelihoods. The results show that livestock numbers have generally declined due to disease outbreaks and distress selling of livestock, which are most prevalent during droughts. These have in turn led to a myriad of impacts, including: i) reduction of cultivated land area, ii) reduction of school-related expenditure, iii) households sliding on the poverty scale, and iv) reduction of expenditure on other household needs such as clothing. However, the extent to which these have been experienced varies by livestock system and poverty status of the household. Districts that rear less resilient livestock species, such as cattle, are more likely to perceive severe effects of livestock-related shocks, which tend to be worse when they are also poor.

Full textAbstract:
Currently, large volumes of data are being collected on farms using multimodal sensor technologies. These sensors measure the activity, housing conditions, feed intake, and health of farm animals. With traditional methods, the data from farm animals and their environment can be collected intermittently. However, with the advancement of wearable and non-invasive sensing tools, these measurements can be made in real-time for continuous quantitation relating to clinical biomarkers, resilience indicators, and behavioral predictors. The digital phenotyping of humans has drawn enormous attention recently due to its medical significance, but much research is still needed for the digital phenotyping of farm animals. Implications from human studies show great promise for the application of digital phenotyping technology in modern livestock farming, but these technologies must be directly applied to animals to understand their true capacities. Due to species-specific traits, certain technologies required to assess phenotypes need to be tailored efficiently and accurately. Such devices allow for the collection of information that can better inform farmers on aspects of animal welfare and production that need improvement. By explicitly addressing farm animals’ individual physiological and mental (affective states) needs, sensor-based digital phenotyping has the potential to serve as an effective intervention platform. Future research is warranted for the design and development of digital phenotyping technology platforms that create shared data standards, metrics, and repositories.

Full textAbstract:
Organic farming has become an important part of Czech agriculture. The aim of this study is an evaluation of the technical efficiency of Czech organic farms and determining the main factors, including subsidies, which affect the technical efficiency of both conventional and organic farms. The Farm Accountancy Data Network Czech Republic (FADN CR) database provides sufficient panel data for this kind of research focusing on types of farming with livestock production. The methodological tool used to achieve the aim of this paper is the parametric stochastic frontier analysis, “True” Random Effects model, supposing farms heterogeneity and time variant determinants of inefficiency. The results of the research verified differences in the technical efficiency of organic and conventional agriculture related both to the different farming methods and to the production conditions. The type of farming and the economic size of farms influence the farms’ profitability, economic performance and comparability with conventional farms. The technical efficiency of organic farming is growing over the long term. Farms with growing technical efficiency show a decline in the proportion of operating subsidies to production, irrespective of their classification in quartiles by the technical efficiency estimate.

Illness or injury to a show animal may be preventable by following a few guidelines. Providing a clean and safe environment and properly feeding, watering, and vaccinating animals will help to reduce the risks of experiencing illnesses and injuries. Owners should also learn how to identify signs of health problems, such as sudden changes in behavior or appearance, and prepare a first aid kit for use in the event of an emergency. Also, being familiar with emergency treatment guidelines will help owners protect themselves, prevent further injury to the animal, and properly administer care to the animal if appropriate.

Full textAbstract:
Incidents affecting the livestock industry are unavoidable in today's society. These incidents can happen at livestock shows across the country putting thousands of exhibitors, visitors, employees and livestock in danger. The purpose of this study was to determine local officials' perceptions and awareness of incident planning and response pertaining to selected livestock shows. Little research has been completed in this area; therefore, this foundational study was needed.
The objectives of this study were to determine local officials' awareness of livestock shows and incident response plans for those livestock shows. In addition, the researcher wanted to describe the roles of local officials in incident planning and response at livestock shows. Level of communication and perceptions of challenges at livestock shows and among local officials were also evaluated. Lastly, the researcher wanted to describe local officials' recommendations for effective incident planning and response related to livestock shows.
Five participants remarked on the value of this study and agreed to participate. These participants included livestock show officials involved in incident planning and response or local emergency management officials. Each participant was interviewed, and then data were transcribed and categorized to consensus. Nine themes arose including: background information, challenges, communication, example incidents, executing incident response, incident response planning, incident response training, miscellaneous and need for planning.
It was concluded that all participants were aware of the selected livestock shows. However, levels of awareness varied by participant due to work-related experiences with the livestock show. The two livestock show participants were aware of specific incident response plans for the livestock show, while the three local emergency management officials were aware of city emergency management plans. Each participant remarked upon their roles in planning and executing incident response. In addition, communication was thought to be one of the key factors to successful incident planning and response. Challenges ranging from lack of communication to training for incident response were stated. Lastly, participants remarked on recommendations for others planning for incident response at livestock shows. These recommendations included communication, preplanning, building relationship with key stakeholders, training, and a need for more planning and research in this area.
It is recommended that this study be replicated with scaled objectives for measuring awareness of livestock shows and incident response plans. Also, replicate this study to determine level of training in incident response and safe handling of livestock. It is recommended to describe communication between livestock shows and local emergency management officials. Lastly, it is recommended to replicate this study with regional livestock shows and state fairs.

AbstractThis chapter analyzes the impact of climate change and variability on food security of rural households in the central highlands of Ethiopia taking Basona Werana district as a case study site. Data were obtained from 123 households selected using simple random sampling from three agro ecological zones. Key informant interviews and focus group discussion (FDG) were used to supplement the data obtained from household survey. The monthly rainfall and temperature data are for 56 points of 10 × 10 km grids reconstructed from weather stations and meteorological satellite observations, which cover the period between 1983 and 2016. Standardized rainfall anomaly (SRA), linear regression (LR), and coefficient of variation (CV) are used to examine inter-annual and intra-annual variability of rainfall. Annual and seasonal rainfalls show decreasing trends over the period of observation. The decreasing trends in annual and March–May (Belg) rainfall totals exhibit statically significant decreasing trends at p = 0.05 level. Kiremt (June–September) shows statically significant decreasing trends at p = 0.1 level. Mean annual maximum and minimum temperatures show statically significant increasing trends at p = 0.05 level. More than 80% of households perceived that the climate is changing and their livelihoods (crop and livestock production) are impacted. The district belongs to one of the most vulnerable areas to climate change and variability in the country where large proportions of households (62%) are under different food insecurity classes. Results suggest that local level investigations are useful in developing context-specific climate change adaptation.

Abstract Wealth creation and poverty alleviation processes in the forest-bounded areas entail the use of such forests to a greater extent. Studies elsewhere show that there is often a tendency to use such forests until they are depleted before technology comes in to improve livelihoods. In this chapter, we examine community livelihoods in relation to ecosystem integrity for communities surrounding the Makere Forest Reserve, particularly socio-economic characteristics of communities, their links to forest utilization and implications for ecosystem integrity. We used mixed methods to collect data: (i) a household questionnaire; (ii) focus group discussions; (iii) key informant interviews; and (iv) a literature review, backed up with satellite imagery. Quantitative and qualitative data collected were subjected to statistical and non-statistical tests, respectively, with the use of Statistical Package for Social Sciences (SPSS) computer software for quantitative data analysis. Livelihood activities in the area include shifting cultivation, livestock keeping, firewood fetching, charcoal making, harvesting timber and illegal logging. The motive for such forest exploitation is both for meeting household needs as well as for wealth accumulation. Forest users take part in such activities regardless of the distance they have to travel from their villages to come to the forest areas. We found education is an integral part of wealth status, but had nothing to do in terms of improving livelihood activities for ecosystem integrity. The absence of livelihood diversification of farm-related activities penetrates into weak forest governance strategies resulting in proliferation of deforestation and forest degradation. To maintain forest integrity, integrated approaches in forest management and alternative livelihood activities are needed such as beekeeping, fishing and modernized livestock keeping. These activities have the potential to increase household food and income and alleviate poverty levels without compromising ecosystem integrity.

Full textAbstract:
Abstract In developing countries like Tanzania, societal vulnerability to the risks of climate change and variability (CC&V) exacerbate ongoing social and economic challenges because people's livelihoods are largely dependent on resources that are sensitive to climate change such as agriculture. Although studies show that most communities in Africa have low adaptive capacity, for centuries people have developed traditional adaptation strategies to face climate inter-annual variability and extreme events based on their long-term experiences. Various studies show how CC&V have impacted the socio-economic and and environmental conditions among the pastoral and agropastoral societies. However, little emphasis has been given to studying the community's resilience status to CC&V impacts. Much of the focus has been placed on studying the community vulnerability and impacts of CC&V as well as coping and adaptation strategies to avert CC&V impacts. Little is known on how the interaction between society and nature can enhance or reduce community resilience under changing climate. The study was conducted in two villages, Ibulyu and Mahaha, in Bariadi District. The main objective of the study was to deepen our understanding of the socio-ecological resilience of agropastoral communities to CC&V impacts in a semi-arid district. The study employed both qualitative and quantitative research designs. Quantitative data were captured through a household survey whereas qualitative data was collected through focus group discussion, key informant interviews and field observation. The results show that CC&V have negatively affected the farming system in the study area. The ecological setting of the area has significantly been altered to the extent that it cannot provide the required ecosystem services and products that are important for human and livestock sustainance. Changes in the production system have negatively affected community resilience and increased their vulnerability.

AbstractThe existing evidence suggests that there is a reverse gender gap in higher education in Mongolia. Prior studies on the reverse gender gap in education were based on the gross enrolment rates and did not delve deeper in terms of using empirical data analyzed over an extended time-period. This paper investigates gender bias in the households’ expenditure on higher education and tracks changes over the ten-year period from 2008 to 2018 using empirical data. In this regard, this study examines the factors and determinants responsible for the gender bias in the households’ expenditure on higher education. To address these questions, the study employs the Engel Curve approach (unconditional educational expenditure) and Hurdle model, which estimates bias in the enrolment decisions and bias in the conditional educational expenditure, both at the household and individual level in 2008 and 2018, using the Household Socio-Economic Survey of Mongolia. Its findings illustrate that gender bias in households’ expenditure on higher education does exist, and it favors girls over boys at the household and individual levels in 2008 and 2018. The findings show that households allocate a greater share of education expenditure to females aged 16–18 and 19–24 than to their male counterparts. Statistical analysis suggests that households’ residence and the occupation of household heads are two important factors affecting this gender bias. Thus, if a household resides in the countryside and its head is employed in the agricultural sector, female offspring are more likely to receive higher education than male offspring. Traditional gender roles and the Mongolian way of life, which centers around attending to livestock and requiring a male labor force and the wage gap, are contextual factors that help explain this gender bias.

AbstractBrachiaria grass is a “climate smart” forage that produces high amount of palatable and nutritious biomass for livestock and performs well in infertile soils, sequesters carbon in soil, and provides several environmental benefits. The objective of the study was to validate the productivity of Brachiaria grass and upscale the suitable cultivars for improved livestock feed resources in Kenya. We assume integrating Brachiaria grass into mixed crop-livestock system will enhance feed availability and livestock productivity, leading to increased food and nutrition security. Farmer participatory approach was adopted to evaluate and promote four Brachiaria grass (Brachiaria decumbens cv. Basilisk, B. brizantha cvs. Xaraes, Piata, and MG-4) in the Central Highland and Eastern Midland of Kenya. The extension/advisory approaches used to promote Brachiaria grass cultivars included field days, village knowledge centres, agricultural shows, posters, and linkages with other institutions through multi-actor platform established under the InnovAfrica project. Generally, Brachiaria grass cultivars were more productive than the control (Rhodes grass) in most harvests reaching peak of 5.1–7.7 t/ha in the fifth harvest. For Rhodes grass, DM was less than 4 t/ha in all harvest and died by sixth harvest. Similarly, based on farmers’ evaluation using phenotypic traits, the Brachiaria grass cultivars had higher score than Rhodes grass except cv. Piata. The mean score ranged from 2.75 to 3.19 for Brachiaria cultivars, while for Rhodes the mean score was 2.63. Within 2 years of intervention, over 4000 farmers in the 2 project sites and additional 1500 farmers from other parts of the country have planted the Brachiaria grass. The demand for Brachiaria grass seeds is increasing due to benefits gained, e.g., increased milk production from dairy cattle fed on the grass. Our study will quantify the associated benefits from cultivation of Brachiaria grass with respect to a set of ecological, food and nutrition security, and social-economic indicators.

Abstract This book chapter focuses on a programme on improving human health through livestock research in three areas: (i) animal-source foods for nutrition; (ii) zoonoses (diseases transmitted between animals and people); and (iii) FBD. This was the first CGIAR group with an explicit food safety mandate (rather than focusing on specific hazards) and with expertise in using research methods for food safety rather than diseases in general. ILRI was also one of the first groups to focus on food safety in the 'informal markets' of developing countries, and by the 2010s, had become the lead research institute globally in this emerging area. ILRI research on FBD has resulted in many science outputs, including some genuinely innovative tools and approaches, and has already demonstrated outcomes at community, national and regional levels. These include substantial inputs into global, regional and national strategies and national training programmes. The major development-oriented approach - the triple-path for training, motivating and enabling of informal market agents - has been shown to be both scalable and sustainable. While questions remain about its lasting effects on food safety and its application outside those few countries where its success has been demonstrated, the next few years should bring further evidence about this, with benefits lasting for many decades to come.

Full textAbstract:
Abstract Despite a growing body of evidence that highlights the economic, social and environmental benefits of mobile pastoralism, few governments are ready to tolerate mobility and many policy makers promote knowingly or inadvertently the policies of sedentarization. This production system seems not to be clearly understood by many and has been characterized as backward, environmentally destructive and economically unsustainable; and the view is that it should be replaced with more sedentary forms of livestock production or other beneficial land uses. The overriding question is whether sedentary livestock keeping is more productive and utilizes fewer resources and less space than the mobile pastoral system. This study carried out a comparative cost-benefit analysis of the two production systems in selected villages of Kiteto and Karatu districts. The aim was to come up with credible data to test this hypothesis. Two alternatives were compared in terms of their net present value (NPV) to test a null hypothesis. The alternative with an NPV greater than zero or higher than its alternative was accepted to be more viable compared with the one with an NPV less than zero or less than its alternative. Whenever the NPV of the sedentary production system in the analysis was shown to be greater than zero and/or greater than the NPV of the mobile pastoral production system the null hypothesis was accepted and vice versa. The study was conducted in Makame village of Kiteto District and Dofa village of Karatu District. Makame village represents a mobile pastoral production system while Dofa village represents a sedentary production system. The study employed a quantitative approach using a household survey in the two villages. The comparative cost-benefit analysis was carried out using monetary values derived from the livestock unit statistical approach. The findings have revealed that the average cost of maintaining a mobile pastoral and sedentary production systems are TSh90,096,333 and TSh112,295,200, respectively. The cost-benefit ratios are 1:0.5 for a mobile pastoral production system and 1:0.25 for the sedentary one.

A global shift away from diets dominated by meat, dairy and eggs to mainly plant-based diets is as necessary in mitigating anthropogenic climate change as the shift away from fossil fuels. Yet a large awareness gap exists about animal agriculture's contribution to greenhouse gas emissions. Recent studies in Australia and the United States show this issue is represented in less than 1 percent of all newspaper articles about climate change. This chapter examines the opportunities and barriers in addressing the livestock sector's impact on climate change. Policy recommendations in the literature are compared with the responses of governments, industry and the NGO sector. Australia's unique socioeconomic and cultural ties to livestock production and the consumption of animal products represent a significant barrier to demand-side mitigation. An analysis of newspaper articles mentioning animal agriculture's link to climate change in The Sydney Morning Herald between 2006 and 2014 provides insights into the facilitation and shaping of public awareness on the issue to date.

Full textAbstract:
Agro-pastoralists in the tropical semi-arid dryland areas of sub-Saharan Africa are significantly affected by climate change and variability. The agro-pastoral families are coping with production-related climatic risks through livelihood diversification to ensure food security. Data were collected from a sample of 411 agro-pastoralists across five districts in the semi-arid northern and central regions of Tanzania through survey conducted between November 2017 and July 2018. Secondary data regarding crop yields and livestock populations for eight years from 2009 to 2017 were collected from the National Bureau of Statistics and the respective District offices. Results show that about three-quarters of the agro-pastoralists managed diversified crop and livestock portfolios with two or more crops and animal species. However, simulated crop yields reveal positive correlations. Construction of integrated portfolios that generate good returns at a modest risk can be achieved through strategic choices between high-return high-risk and low-return low-risk crop and livestock activities. Thus, the paper recommends for costly long-term breeding and genotype improvement programs, strategically changing the make-up of the current crop and livestock portfolios which appear to be an affordable and tailored solution for building risk resilience among agro-pastoral communities in the drylands.

Full textAbstract:
This report consists of a top-level aggregate analysis of the total potential for converting livestock manure into a domestic renewable fuel source (biogas) that could be used to help states meet renewable portfolio standard requirements, reduce greenhouse gas (GHG) emissions, and improve air quality. In the U.S. livestock produces over one billion tons of manure annually. Typical disposal methods for animal manure allow for the emission of ammonia, particulate matter, unpleasant odors, volatile organic compounds (VOCs) and a variety of other air pollutants, which can damage the environment and pose risks to animal and human health. These disposal methods also allow for the uncontrolled emission of methane and nitrous oxide, two potent greenhouse gases (GHGs), with 21 and 310 times the global warming potential of carbon dioxide, respectively. Annually, 51 to 118 million metric tons (MMT) of carbon dioxide equivalent are emitted from livestock manure alone. Because air quality problems are on the rise, and trends show the contribution to GHG emissions from manure increasing from 1990 to 2005, limiting emissions from manure represents a valuable starting point for improving air quality and mitigating global climate change. Through anaerobic digestion, a well-known and time-tested process, animal manure is converted to methane rich biogas and many of the emissions of common manure management practices are avoided. Biogas is useful in a variety of applications such as a coal or natural gas substitute in electricity generation, which is the scenario considered in this analysis. Using values for the amount of biogas that can be produced per animal unit (defined as 1000 pounds of animal) per day and the number of animal units in the U.S., the authors determined that the 95 million animal units in the country could produce nearly 1 quad of renewable energy per year, approximately 1% of the U.S. total energy consumption. Converting the biogas into electricity using standard microturbines could produce 88 ± 20 billion kWh, or 2.4 ± 0.6% of annual electricity consumption in the U.S. Such an approach replaces two relatively dirty energy sources—manure and coal combustion—with a relatively cleaner source, biogas combustion, thereby yielding a net potential GHG emissions reduction of 99 ± 59 million metric tons or 3.9 ± 2.3% of the annual GHG emissions from electricity generation in the U. S. In addition, this approach has the potential to eliminate 0.4 ± 0.09 MMT of sulfur dioxide emissions, 0.1 ± 0.03 MMT of NOx, 0.002 MMT of mercury, and 0.69 ± 0.12 MMT of particulate matter from coal combustion. When natural gas is displaced, biogas use could eliminate 0.083 ± 0.019 of NOx and 0.006 ± 0.001 of SO2 while biogas combustion would emit approximately 0.068 MMT of NOx, 0.007 MMT of carbon monoxide, 0.005 MMT of particulate matter, 0.002 MMT of sulfur dioxide and 0.002 MMT of VOCs.

Full textAbstract:
The implementation of the Common Agricultural Policy of the EU in the Czech Republic brought many changes in the functioning and financing of agriculture in the Czech Republic with political, economic, and social impacts and many challenges and threats for Czech farmers. Since the Czech Republic acceded to the EU, the Common Agricultural Policy has been reformed several times. The aim of the article is to evaluate the impact of the Common Agricultural Policy on Czech farmers in 2014–2020. The evaluation is based on a qualitative survey among selected farmers in the Moravian-Silesian and Olomouc regions. The research results show that enterprises positively evaluate financial stability and the overall protection of the agricultural sector. Support for the diversification of agriculture and support for the investment was also highlighted. On the contrary, the administrative burden, great emphasis on cross compliance rules, differences in the payments in EU countries, reducing the competitiveness of Czech agriculture and unfavourable conditions for livestock farmers were assessed negatively.

Full textAbstract:
During the cold winter months in the Midwestern States, a common problem that many livestock farmers face is to prevent the cattle drinking water, in a stock tank, from freezing. There are commercial water heating systems that consist of drinking fountains, submersible, or floating heaters. However, these units have typically high initial and operating costs. In this paper, we present the analysis and design of a low cost solar system that are made with tractor inner tubes and other readily available materials. Car and tractor inner tubes make good solar collectors because of their mechanical strength and thermophysical properties. The low cost solution reported here could also be used to address warm water supply and or space heating needs in developing countries. In this paper, the transient thermal response of wooden stock tanks with Fourier numbers around 0.01 is considered. Exact analytical solutions in the form of infinite series are used. The product solution of a cylinder and a plane wall is used to model the stock tank. Moreover, given the small Fourier number, a series of numerical experiments were performed to determine the number of terms that must be retained from the infinite series solutions to obtain accurate results. A theoretical model for the solar collector was also developed, and a series of physical experiments were performed to verify the theoretical models of the stock tank and the collector. The experimental results show that theoretical models, developed in this paper, predict the thermal behaviors of the collector and the stock tank well.

Full textAbstract:
The fate of transgenic DNA (tDNA) and protein from feed derived from Genetically Modified organisms (GMOs) in animals has been a major issue since their commercialization in 1996. Several studies have investigated the risks of horizontal gene transfer (HGT) of tDNA and protein to bacteria or animal cells/tissues, but some of the reported data are controversial. Previous reports showed that tDNA fragments or proteins derived from GM plants could not be detected in tissues, fluids, or edible products from livestock. Other researchers have shown that there is a possibility of small fragments entering animal tissues, fluids and organs. This motivated us to update our knowledge about these concerns. Therefore, this review aimed to evaluate the probable transfer and accumulation of tDNA/proteins from transgenic feeds in animal samples (ruminant and non-ruminant) by evaluating the available experimental studies published scientifically. This study found that the tDNA/protein is not completely degraded during feed processing and digestion in Gastro-Intestinal Tract (GIT). In large ruminants (cattle), tDNA fragments/proteins were detected in GIT digesta, rumen fluid, and faeces. In small ruminants (goats), traces of tDNA/proteins were detected in GIT digesta, blood, milk, liver, kidney, heart and muscle. In pigs, they were detected in blood, spleen, liver, kidney, and GIT digesta. In poultry, traces were detected in blood, liver and GIT digesta but not in meat and eggs. Notwithstanding some studies that have shown transfer of tDNA/protein fragments in animal samples, we cannot rely on these few studies to give general evidence for transfer into tissues/fluids and organs of farm animals. However, this study clearly shows that transfer is possible. Therefore, intensive and authentic research should be conducted on GM plants before they are approved for commercial use, investigating issues such as the fate of tDNA or proteins and the effects of feeding GM feed to livestock.

Full textAbstract:
The Ayrshire dairy breed is renowned for producing large quantities of high quality milk and, therefore, is frequently used for crossbreeding. However, various hereditary anomalies caused by gene mutations have been recently recorded in calves produced by some Ayrshire sires. Most of these anomalies were shown to have a recessive inheritance pattern, thus imposing a threat of unpredictable dramatic changes in cattle genotypes under such factors as genetic drift, selection and inbreeding. The purpose of this study was to examine the susceptibility of the Ayrshire cattle bred in the North Caucasus to such hereditary abnormalities as complex vertebral malformation (CVM) and bovine leukocyte adhesion deficiency (BLAD). The investigation was carried out on 16 cows with various phenotype and reproduction disorders that were selected based on a three-year veterinary observation of 440 livestock animals. The target group cows were generally the descendants of Hannulan Yaskiyri, Riihiviidan Urho Errant and O.R. Lihting. The results demonstrated that no animals under study were the carriers of these genetic disorders, which proved the mutant alleles of BLAD and CVM to be absent from the Ayrshire cattle livestock bred in the North Caucasus. Therefore, the sires of these cattle can be successfully used for breeding.

Full textAbstract:
Food contamination has aroused public concern since Fukushima accident. As emergency preparedness is often viewed as an important approach to protect staff working on site and public around the site, ingestion emergency planning zone (EPZ) is applied to protect public from the exposure of contaminated food. Ingestion EPZ is one of the technical foundations for nuclear emergency preparedness, which will be influenced by design features of plant and characteristics of the site. This paper is devoted to the research on the optimization of ingestion EPZ sizing from the view of the atmospheric dispersion model and the food chain model, which are crucial points for the sizing of ingestion EPZ. Compared to the traditional straight-line Gaussian plume model with a quite conservative assumption that plume segments always transport in the downwind direction, the Lagrangian Gaussian puff model considers the swing of wind direction over time, which makes the simulation more realistic. With the results of radionuclide concentrations evaluated by the dispersion model, the transportation of the radionuclides in food is simulated by the food chain model. The traditional food chain model is essentially a static model with no consideration that food contamination level has a strong dependence on the accident date, which may overstate the risk from nuclear plant accidents and result in unfounded fear of public. The dynamic food chain model, which takes daily changes of plant biomass, or livestock feeding periods in consideration, has been developed to estimate radionuclide concentrations in different foodstuffs. On basis of the study of the dispersion models and food chain models above, we evaluate the ingestion EPZ size of Tianwan NPP by choosing the comparatively realistic ones from them. In the scenario considered in this paper, the simulation domain of Tianwan NPP within 80km-range and hourly time-step is applied, and meteorological conditions are carefully set according to observation data in recent years. Results show that there is significant margin and conservatism in the traditional ingestion EPZ sizing. Radionuclide concentrations predicted by the Lagrangian Gaussian puff model is almost an order of magnitude lower than the Gaussian plume model. Moreover, the dynamic food chain model considers the seasonal effect that simulation results of radionuclide concentrations in foodstuffs are significantly higher in summer than in winter, which helps to make a more realistic consideration of ingestion pathway. This research gives an example of the application of new models for the optimization of ingestion EPZ sizing, which may contribute to strengthen public confidence in nuclear safety and emergency preparedness.

Full textAbstract:
The convergence of a favorable macroeconomic environment and high prices of primary commodities between 2000 and 2011 contributed to the best performance of agriculture in Latin America and the Caribbean (LAC) since the 1980s, with steady growth of total factor productivity (TFP) and output per worker and a reduction in the use of input per worker. The end of the upward phase of the commodity cycle in 2011 together with less favorable external markets and a deterioration of the policy environment in several countries, motivates us to revisit the situation of agriculture in LAC in recent years to analyze how these changes have affected its performance. This study applies a framework that uses index numbers together with data envelopment analysis (DEA) to estimate levels of productivity and efficiency, incorporating technical change together with technical (TE) and environmental efficiency (EE) into the decomposition of TFP. The EE index adjusts the TFP measure for pollution, treating GHG emissions as a by-product of the desired crop or livestock outputs. TFP and efficiency of crop and livestock sub-sectors was calculated for 24 LAC countries from 2000 to 2016. Our results show that the period of fast agricultural growth in LAC, driven by technical change and resource reallocation, transformed agriculture in the region leaving it in a better position to cope with the more unfavorable regional macroeconomic environment and the less dynamic global markets observed after 2011.

Available data provide a picture for the macro-economy of Colombia, agriculture, and infrastructure. Recent data on trends on public procurement were difficult to find within the scope of this rapid review. In 2020, macro-level employment figures show a large drop between February and April when COVID-19 lockdown measures were first introduced, followed by a gradual upward trend. In December 2020, the employment rate was 4.09 percentage points lower than the employment rate in December 2019. Macro-level figures from the National Administrative Department of Statistics (DANE) show that a higher percentage of men experienced job losses than women in November 2020. However, the evidence presented by the Universidad Nacional de Colombia based on the DANE great integrated house survey shows that a higher proportion of all jobs lost were lost by women in the second quarter. It may be that the imbalance shifted over time, but it is not possible to directly compare the data. Evidence suggests that women were disproportionately more burdened by home activities due to the closure of schools and childcare. There is also a suggestion that women who have lost out where jobs able to function during lockdowns with technology are more likely to be held by men. Literature also shows that women have lower levels of technology literacy. There is a lack of reliable data for understanding the economic impacts of COVID-19 for people living with disabilities. A report on the COVID-19 response and disability for the Latin America region recommends improving collaboration between policymakers and non-governmental organisations. Younger people experienced greater job losses. Data for November 2020 show 3.3 percent of the population aged under 25 lost their job compared to 1.8 percent of those employed between 24 and 54. Agriculture, livestock, and fishing increased by 2.8% in 2020 compared to 2019. And the sector as a whole grew 3.4% between the third and fourth quarters of 2020. In terms of sector differences, construction was harder hit by the initial mobility restrictions than agriculture. Construction contracted by 30.5% in the second quarter of 2020. It is making a relatively healthy recovery with reports that 84% of projects being reactivated following return to work.
