Abstract:
The chicken industry, in which broiler chickens are bred, is the largest poultry industry in Taiwan. In a traditional poultry house, breeders must usually observe the health of the broilers in person on the basis of their breeding experience at regular times every day. When a breeder finds unhealthy broilers, they are removed manually from the poultry house to prevent viruses from spreading in the poultry house. Therefore, in this study, we designed and constructed a novel small removal system for dead chickens for Taiwanese poultry houses. In the mechanical design, this system mainly contains walking, removal, and storage parts. It comprises robotic arms with a fixed end and sweep-in devices for sweeping dead chickens, a conveyor belt for transporting chickens, a storage cache for storing chickens, and a tracked vehicle. The designed system has dimensions of approximately 1.038 × 0.36 × 0.5 m3, and two dead chickens can be removed in a single operation. The walking speed of the chicken removal system is 3.3 cm/s. In order to enhance the automation and artificial intelligence in the poultry industry, the identification system was used in a novel small removal system. The conditions of the chickens in a poultry house can be monitored remotely by using a camera, and dead chickens can be identified through deep learning based on the YOLO v4 algorithm. The precision of the designed system reached 95.24% in this study, and dead chickens were successfully moved to the storage cache. Finally, the designed system can reduce the contact between humans and poultry to effectively improve the overall biological safety.

Abstract:
One of the problems in growing and keeping poultry, both in industrial and farm and kitchen garden environments is ectoparasites, which are responsible for lowering the productivity of poultry and causing economic losses. The study of the prevalence and diagnosis of bird ectoparasites on poultry farms with different maintenance technologies is important for the further development of integrated methods for combating them. Our research was conducted during 2006–2017 in 16 regions of Ukraine and the Autonomous Republic of Crimea. In total, 38 poultry farms specializing in egg production with poultry kept in battery cages, 18 poultry houses specializing in egg production with poultry kept on the floor and more than 150 farm and kitchen garden poultry houses for keeping chickens, turkeys, quails, guinea fowl and pigeons were examined. We found that, both with battery cages and when poultry are kept on the floor in poultry farms, the most common ectoparasites are chicken mites (Dermanyssus gallinae), which causes the disease of dermanyssiosis. It was determined that the extensivity of the invasion was, on average, from 56% to 80%. Also, in the chickens and turkeys, mallophages (Menopon gallinae, Menacanthus stramineus), which cause mallophagoses, were detected, and the extensivity of the invasion ranged from 27% to 45%. In farms and kitchen gardens where chickens, guinea fowl and quails were kept, the number of chicken mites in 1 g substrate was more than a thousand live mites, in dovecotes chicken mites were found in 50% to 100% of nests. In chickens and turkeys, besides the chicken mite, bird lice were found. In chickens, extensivity of invasion of M. gallinae, M. stramineus, Lipeurus variabilis, ranged from 15% to 22%, in turkeys, extensivity of invasion of M. gallinae and M. stramineus ranged from 16% to 25%. The scaly leg mite (Knemidocoptes mutans), which causes the disease knemidocoptiasis ("lame leg"), was detected in incubating hens over the age of two years, the extensivity of the invasion ranged from 5% to 7%. It was established that in poultry farms, both in battery cages and when the birds were kept on the floor, the main ectoparasite in chickens, guinea fowl and quail is red chicken mite (D. gallinae), and on poultry farms and kitchen gardens in addition to the chicken mite, three types of bird lice (M. gallinae, M. stramineus, L. variabilis) and K. mutans were found.

Abstract:
The rearing of indigenous chickens is an integral part of the smallholder farming systems in developing countries, where they are kept by the rural poor to satisfy multiple functions Thus, the growth performance of Nigerian Fulani ecotype chicken (NFEC) under intensive and pastured poultry production systems was evaluated. Two hundred, day-old chicks of Nigerian Fulani ecotype chicken (NFEC) were obtained. The chickens were separated randomly to intensive and pastured poultry production systems at 12 weeks of age. Data on body weight ® were taken weekly from day-old to 20 weeks. Data were analyzed using PROC GLM of SAS at statistical significance level of P<0.05. Results showed significant effect of sex of chicken th th from the 10 to the 20 week of age (P<0.05). Significant interaction effect was observed between sex and production system at weeks 16 and 18 (P<0.05) when the male chickens under the intensive production system outpaced their male counterparts in the pastured poultry. Average daily gain for the period of 20 weeks was 6.83g and 9.21g for female and male chickens, respectively. Weight gain pattern across weeks was not uniform. There was no significant difference in the growth rate in the two production systems (P>0.05). The study revealed that little disparity exists in growth performance of NFEC under the pastured and deep-litter production systems.

Abstract:
Astroviruses are small, round, nonenveloped viruses with star-like morphology and a diameter of 25-35 nm, and their genome constitutes linear, positive-sense ssRNA of about 7 kb of size. Astroviruses are known to cause enteritis in humans, as well as in different animal species, including sheep, cattle, swine, dogs, cats and mice. In poultry, they cause enteritis combined with growth depression and higher mortality, but may also cause other pathological conditions. Duck astrovirus (DAstV) infections trigger hepatitis with a high morbidity and mortality of ducklings. Infections of chickens with avian nephritis virus (ANV) cause diarrhea, growth retardation, kidney damage and gout, resulting in increased mortality. Recently, another member of this group, chicken astrovirus (CAstV), has been described as the etiological factor of “white chicks” condition. Astroviruses have also been detected in domestic geese, guinea fowl, pigeons and different species of wild aquatic birds, and all of them belong to the Astroviridae family, the Avastrovirus genus. Initially, they were further divided into separate species, depending on their host of origin. According to these criteria, six different astroviruses were identified in avian species – in turkeys: turkey astrovirus type 1 (TAstV-1) and type 2 (TAstV-2), in chickens: ANV and chicken astrovirus, and in ducks: DAstV type 1 (DAstV-1) and type 2 (DAstV-2). However, since astroviruses can be transmitted between different species, this classification was replaced with one based on the amino acid structure of viral capsid protein. Currently, astroviruses detected in avian species are classified into three official avastrovirus species: 1, 2, and 3. This review presents data on the replication, pathogenesis, and diagnosis of astroviruses, as well as on the control and prevention of astrovirus infection.

Abstract:
This study examines the factors that cause failures of many South African rural small and medium enterprises (SMEs) in poultry business. The research method was qualitative phenomenology using in-depth, semi-structured interviews to explore the factors considered by rural chicken SMEs owners to be causes of their business difficulties. The study revealed that these entrepreneurships knew chicken business only from the home-grown chickens, and the local poultry was usually providing only meat. Compared to the local chickens that were cheap to acquire and nurture, the commercial ones had to be purchased, nourished with purchased foods, supported with electricity light at night, and still, some died. It was much cheaper to raise indigenous chickens. The results indicate that rural poultry SMEs owners did not know that buying a commercial chick carries benefits that range from eggs, feathers, meat, and other chicken products. Also, after purchasing each chick, there are more additional investments needed to maintain the market standard. The study enlightens chicken entrepreneurs that they should, first, learn the insight of business, the poultry industry, and the context of the business they wish to pursue.

Abstract:
Abstract Poultry constitutes an important economic activity for the rural poor in many African countries. Additionally in many rural families, poultry provides the family with a low cost, highly efficient and nutritious protein. Unfortunately, the smallholder farmers in rural areas often do not have access to these improved genetics. The access to an improved low-input and dual-purpose chicken to supplement the local indigenous breeds could transform the rural poultry enterprise. In some countries, investments are made to support the African Poultry Multiplication Initiative (APMI) or other comparable structures. The APMI generally operates through capable local private companies to establish a parent stock (PS) and hatchery operation for the supply of improved dual purpose chicken breeds to farmers in their communities. The day-old-chicks from the PS farm are transported to so called “Brooder Units” who will specialize in the brooding, feeding, and proper vaccination process for the first 30–40 days of the chicks life. Through this system, local smallholder farmers have access to improved genetics and the chickens have a high chance to survive due to their good start. Recently Hendrix Genetics received a grant from the Bill & Melinda Gates Foundation to further enhance the use of improved poultry genetics in rural Africa. The program named “Sustainable Access to Poultry Parent Stock for Africa (SAPPSA)” aims to 1) secure access of poultry parent stock, 2) grow the APMI-like initiatives within and across countries and 3) improve the dual purpose better breeds for African smallholder farmers. By securing access to high quality PS and improving the breeding program of dual-purpose breeds under African conditions, the APMI can be better implemented in African countries. It will result in 1) increase poultry production and productivity, 2) increase rural household income 3) improved household nutrition and 4) empowerment of women.

Abstract:
Poultry farming has the risk of being attacked by various diseases. One effort to protect the poultry, particularly layer chickens is by implementing a biosecurity system to prevent death due to diseases [1]. The area where most breeders have implemented a biosecurity system is located in Lendah, Kulonprogo because, in 2015, chickens in the district were attacked by Newcastle disease called Tetelo. This study aims to evaluate the implementation of the biosecurity system by analyzing the conditions and the success rate of this system on layer chicken farming, as well as the attitudes of breeders toward the system. The respondents were gathered using census, and the data were analyzed by measuring variables in aspects of biosecurity conditions using a rating scale. The Spearman Rank measured the correlation, whereas breeders’ attitudes toward the implementation of biosecurity were measured qualitatively. The results showed that the implementation of the biosecurity system was at a moderate level, and chicken mortality was quite high. The attitudes of the breeders toward the layer chicken’s biosecurity system as a whole belonged to the good category. In conclusion, layer chicken breeders had a positive response to the biosecurity system.

The purpose of this community service is to prevent the incidence of Newcastle Disease in domestic poultryin Marga Dauh Puri Village, Marga Subdistrict, Tabanan Regency. Newacastle disease is highly contagiousand can cause high mortality in poultry. Kampong chickens has the potential as a transmitter of Newcastledisease because the maintenance system is semi extensive. Banjar Ole is part of the village of Marga DauhPuri, where there are many kampong chickens kept extensively. The village of Marga Dauh Puri is highlypotential for contracting Newcastle disease, as it is a chicken trade traffic route from Penebel to Denpasar.Community service activities carried out on September 24, 2017, covering the ways of raising chickens andpreventing Newcastle Disease by vaccination. Noted there are 450 poultry in Banjar Ole, as many as 372(82.6%) successfully vaccinated. This is due to some kampong chickens not extensively so not all can bevaccinated. The amount is sufficient for vaccination coverage to produce group immunity. In order to proofthat the vaccination program is appropriate, ten blood samples were collected and antibody titer was testedprior vaccination (was found to have a mean antibody titer of 22.2 HI units) which means under protective titer(24 HI units).

Abstract:
Immunosuppression of commercial chickens is a serious animal health and economic problem in the poultry industry. The major causes of the immunosuppression are viruses that suppress transcription of interferon genes, especially interferon alpha. There is a need for monitoring immunosuppression in commercially bred chickens. For this purpose, the absolute abundance of interferon alpha transcripts can be measured in blood of chickens by a suitable assay. Such an assay was used to estimate abundance of chicken interferon alpha in a sample of splenic cells induced with polyinosinic polycytidylic acid. The abundance measured was 29 ± 2 attomoles/µg total RNA. This assay can be performed in microtitre plates using samples collected from chickens in poultry houses.

Abstract:
Thesis (MA. Agric. (Animal Production)) -- University of Limpopo, 2014<br>This study determined the effect of carrot meal supplementation on productivity and carcass characteristics of Arbor acres broiler chickens aged one to six weeks. Experiment I determined the effect of carrot meal supplementation on productivity of Arbor acre broiler chicks aged one to 21 days. Two hundred unsexed Arbor acre broiler chickens were randomly assigned to five treatments with five replicates, each replicate having ten birds. A completely randomized design was used in the first experiment. The treatments were 0 (UA0), 20 (AU20), 50 (AU50), 75 (AU75) or 100 (AU100) g of carrot meal supplementation per kg DM feed. Quadratic equations were used to determine levels of carrot meal supplementation for optimal feed intake, metabolisable energy intake and nitrogen retention of Arbor acre broiler chickens aged one to 21 days. Linear equations were used to determine relationships between carrot meal supplementation and productivity variables. Dietary carrot meal supplementation had no (P>0.05) effect on growth rate, live weight and feed conversion ratio of unsexed Arbor acre broiler chickens aged one to 21 days. Carrot meal supplementation, however, improved (P<0.05) metabolisable energy intake and nitrogen retention of the chickens. Dietary metabolisable energy intake and nitrogen retention of the chickens were optimized at different carrot meal supplementation levels of 40.5 and 53.57 g/kg DM feed, respectively. No chicken deaths were recorded. Experiment II determined the effect of carrot meal supplementation on productivity and carcass characteristics of female Arbor acre broiler chickens aged 22 to 42 days. The chickens were randomly allocated to five treatments with five replicates, each having 10 birds, in a completely randomized design. The supplementation levels were 0 (FA0), 20 (FA20), 50 (FA50), 75 (FA75), or 100 (FA100) g of carrot meal per kg DM feed. Quadratic equations were used to determine levels of carrot meal supplementation for optimal feed intake, feed conversion ratio, live weight, metabolisable energy intake and nitrogen retention of broiler chickens aged 22 to 42 days. Linear equations were used to determine relationships between carrot meal supplementation and production variables. Dietary carrot meal supplementation had no (P>0.05) effect on growth rate, live weight and carcass parts of female Arbor acre broiler chickens aged 22 to 42 days. Carrot meal supplementation improved (P<0.05) feed intake, feed conversion ratio, metabolisable energy intake and nitrogen retention of Arbor acre broiler chickens aged vi 22 to 42 days. Dietary feed intake, feed conversion ratio, live weight, metabolisable energy intake and nitrogen retention were optimized at different dietary carrot meal supplementation levels of 52.8, 63.8, 38.0, 42.0 and 44.3 g/kg DM feed, respectively. Dietary carrot meal supplementation had no effect (P>0.05) on tenderness and flavour of female Arbor acre broiler meat. Broiler chickens on diets supplemented with 20, 50 or 100 g of carrot meal per kg DM feed produced meat with better (P<0.05) juiciness values than those of meat from chickens not supplemented with dietary carrot meal and those supplemented with 75 g/kg DM feed. There was a positive relationship between carrot meal supplementation and chicken meat juiciness. It is concluded that carrot meal supplementation improved (P<0.05) metabolisable energy intake and nitrogen retention of unsexed Arbor acre broiler chickens aged one to 21 days. However, carrot meal supplementation had no effect (P>0.05) on growth rate, live weight and feed conversion ratio of unsexed Arbor acre broiler chickens aged one to 21 days. Carrot meal supplementation improved (P<0.05) intake, feed conversion ratio, metabolisable energy and nitrogen retention of female Arbor acre broiler chickens aged 22 to 42 days. However, carrot meal supplementation did not (P>0.05) improve growth rate and live weights of the chickens.

Corrigenda inserted behind title page. Bibliography: leaves 275-306. The pattern of body growth and intestinal development of an Australian strain of broiler chicken, the Steggles x Ross (F1) in response to different diets was studied. Five experiments were designed to examine the pattern of growth and mechanisms involved. In four other experiments, the mechanisms underlying the gross response of the broiler chicks to dietary ingredients, anti-nutritive factors and growth enhancers were examined. Results indicated that a rapid development of the small intestine preceded significant overall body growth. Body growth would, however, depend more on the various physiological events such as those related to mucosal growth and renewal, digestive enzyme function, and nutrient transport. Some of the differences observed in productivity of broiler chickens on different diets were traced to events at the intestinal level.

Thesis (MSc. Agriculture (Animal Production)) -- University of Limpopo, 2014<br>Two experiments were conducted to determine the effect of moringa seed meal supplementation on productivity and carcass characteristics of Ross 308 broiler chickens. The first experiment determined the effect of moringa seed meal supplementation on productivity of Ross 308 broiler chickens aged one to 21 days. Two hundred and fifty unsexed day-old Ross 308 broiler chicks were randomly allocated to five dietary treatments, replicated five times, and each replication having 10 chickens. A completely randomized design was used. The chickens were fed on a grower diet supplemented with 0 (M0), 5 (M5), 10 (M10), 15 (M15) and 20 (M20) g of moringa seed meal/bird/day. Moringa seed meal supplementation had no effect (P>0.05) on feed intake, metabolisable energy intake, nitrogen retention, feed conversion ratio and live weight of unsexed Ross 308 broiler chickens. Moringa seed meal supplementation improved (P<0.05) growth rates of unsexed Ross 308 broiler chickens aged one to 21 days. A moringa seed meal supplementation level of 13.3 g/kg DM feed optimized growth rate of Ross 308 broiler chickens aged one to 21 days. The second experiment determined the effect of moringa seed meal supplementation on productivity and carcass characteristics of female Ross 308 broiler chickens aged 22 to 42 days. The chickens weighing 558 ± 10 g/bird were randomly allocated to five treatments with five replications having 10 birds. The chickens, aged 21 days, were allocated to the treatments in a completely randomized design. The chickens were fed on a grower diet supplemented with 0 (FM0), 5 (FM5), 10 (FM10), 15 (FM15) and 20 (FM20) g of moringa seed meal per kg DM. Moringa seed meal supplementation had no effect (P>0.05) on feed intake, growth rate, feed conversion ratio, live weight, metabolisable energy intake, carcass weight, breast meat weight, abdominal fat pad weight, liver weight, heart weight, thigh weight, meat flavour, juiciness and tenderness of female Ross 308 broiler chickens. However, moringa seed meal supplementation improved (P<0.05) nitrogen retention and gizzard weights of female Ross 308 broiler chickens. vi It was concluded that moringa seed meal supplementation improved growth rate of unsexed Ross 308 broiler chickens aged one to 21 days. Similarly, moringa seed meal supplementation increased nitrogen retention and gizzard weights of female Ross 308 broiler chickens aged 22 to 42 days.

Abstract:
AbstractBoth poultry meat and eggs provide high-quality animal protein [containing sufficient amounts and proper ratios of amino acids (AAs)] for human consumption and, therefore, play an important role in the growth, development, and health of all individuals. Because there are growing concerns about the suboptimal efficiencies of poultry production and its impact on environmental sustainability, much attention has been paid to the formulation of low-protein diets and precision nutrition through the addition of low-cost crystalline AAs or alternative sources of animal-protein feedstuffs. This necessitates a better understanding of AA nutrition and metabolism in chickens. Although historic nutrition research has focused on nutritionally essential amino acids (EAAs) that are not synthesized or are inadequately synthesized in the body, increasing evidence shows that the traditionally classified nutritionally nonessential amino acids (NEAAs), such as glutamine and glutamate, have physiological and regulatory roles other than protein synthesis in chicken growth and egg production. In addition, like other avian species, chickens do not synthesize adequately glycine or proline (the most abundant AAs in the body but present in plant-source feedstuffs at low content) relative to their nutritional and physiological needs. Therefore, these two AAs must be sufficient in poultry diets. Animal proteins (including ruminant meat &amp; bone meal and hydrolyzed feather meal) are abundant sources of both glycine and proline in chicken nutrition. Clearly, chickens (including broilers and laying hens) have dietary requirements for all proteinogenic AAs to achieve their maximum productivity and maintain optimum health particularly under adverse conditions such as heat stress and disease. This is a paradigm shift in poultry nutrition from the 70-year-old “ideal protein” concept that concerned only about EAAs to the focus of functional AAs that include both EAAs and NEAAs.

Abstract:
AbstractGlobal climate change poses a great threat to poultry production. Greenhouse gases (GHGs) are released through both natural and anthropogenic sources into the atmosphere. Though poultry production contributes little to the release of GHGs, the subsector has been shown to be greatly affected by climate change and global warming. Poultry production as a major subsector of agriculture has provided the teeming population with a supply of needed animal protein in terms of meat and egg production all over the world. It is yet a major global employer of labor. Though it occupies a vantage position in meeting human needs, it is being threatened by climate change, especially in Africa where necessary structure to tackle the menace is nonexistent. Broiler chickens that are reared mainly for chicken meat cannot tolerate the high ambient temperature that prevails mostly in the tropical environment. Chickens are homeotherms that homeostatically regulate core body temperature within a narrow range. Elevated ambient temperature above thermal comfort zone, such as envisaged in climate change scenarios, will trigger series of neuroendocrine modulations that are detrimental to the welfare and productivity in broiler chickens. Such birds are said to be undergoing heat stress (HS). Negative effects of HS include reduced feed consumption, growth rate, feed digestion and efficiency, immunity, welfare, and survivability. Various adaptive measures that could be harnessed by broiler farmers, ranging from housing, feeding, watering, stocking, breeding for thermo-tolerant strains, thermal conditioning, use of phytochemicals, and much more, are reviewed upon in this chapter.

Abstract:
"A particularly important aspect of immunology is to develop non-invasive methods of obtaining antibodies which could be a great alternative to traditional ones that based on the harmful procedure of isolation of immunoglobulins from animal blood sera. That’s why the extraction of antibodies from poultry egg yolks (IgY) is the most promising. Due to the fact of variation of IgY structural features that determine the definite immunochemical properties, yolk antibodies in comparison with mammalian immunoglobulins (IgG) does not interact with rheumatoid factor (Rf), contribute to the activation of the complement system, bind to the Fc-receptor (FcR), and also has weak cross-reactivity, which confirms the possibility of their widespread use in medicine and food. Also the presence of phylogenetic distance between chickens and mammalians guarantees immune response against conservative mammalian protein molecules which is highly important for the creation of new generation test systems. The aim of this work is to develop a selective method of producing high-purity immunoglobulin Y preparations from the yolk of chicken eggs. There were adopted selective conditions of isolation of IgY under spontaneous thawing procedure at the room temperature of firstly frozen yolk solution in a sodium-phosphate buffer mixed with water (pH 5.0) in a ratio of 1:6, which leads to receiving a water-soluble fraction further precipitated with the sodium chloride at a concentration of 10% of the solution mass and subsequently concentrated using ultrafiltration with membrane UAM-10, that allows achieving the content of IgY not less than 95% per dry substance in immunoglobulin fraction. It is possible to produce a protein fraction with a protein content of at least 9 g/l. The purity of the immunoglobulin fraction was verified using polyacrylamide gel electrophoresis. The presence of a light chain in the IgY solution was proved to be a low-molecular compound using the method of gel-filtration-chromatography. The immunological activity of IgY was studied with respect to bovine serum albumin (BSA) as an antigen. The enzymatic resistance of IgY against proteolytic enzymes was tested in area of the gastrointestinal tract."

Abstract:
In intensive production, freshly hatched cockerels are culled in the layer hatchery (7 billion males each year), On the other hand, for meat production rearing female birds has not economic benefits because of male broiler chicks have a faster growth rate and better feed efficiency than females. In this regards several methods are being developed for sex determination in the chick embryo during the incubation period. But these methods need to be rapid, cost-efficient, and suitable practical for commercial use. Additionally, sex determination should be done before pain perception has evolved in chick embryos. Biotechnology by in ovo technique to sex determination of between male and female chicks or sex reversal could improve production and eliminate ethical dilemmas for poultry industries. In birds, the differentiation of embryonic gonads is not determined by genetic gender with the certainty that occurs in mammals and can be affected by early treatment with a steroid hormone. During the development of the chick embryo, the genotype of the zygote determines the nature of the gonads, which then caused male or female phenotype. The differentiation of gonads during the period called the "critical period of sexual differentiation" is accompanied by the beginning of secretion of sexual hormones. Namely, any change in the concentration of steroid hormones during the critical period affects the structure of the gonads. Many synthetic anti-aromatases such as federazole and non-synthetic in plants, mushrooms, and fruits containing natural flavonoids have been used in the experiments in ovo injection of anti-aromatase had no negative effect on the growth performance of sexual reversal female chickens. In conclusion, administration of an aromatase inhibitor causes testicular growth in the genetic female gender, and estrogen administration leads to the production of the left ovotestis in the genetic male gender. Therefore, in the early stages of embryonic development, sexual differentiation can be affected by changing the ratio of sexual hormones. In this review, effects of some substances applied by in ovo injection technique on sex reversal and performance in chicks.

Abstract:
Contaminating poultry feed and their products with mycotoxins produced by fungi may cause many health effects on animals and human if they were at high concentrations. Therefore, it is imperative to regularly monitor the concentration of mycotoxins specially aflatoxin and ochratoxin A in the poultry feed and their products. In the present study, we demonstrated that Aspergillus flavus was the major contaminant using DNA extraction and gel electrophoresis. Using ELISA kit for ochratoxin A, Ochratoxin A did not exceed the detection limit 50 ng/kg but in one sample has exceeded the European Union maximum limit for aflatoxins of 20 μg/kg through the ELISA aflatoxin All kit. Aflatoxin B1 was detected in chicken liver samples using ELISA aflatoxin B1. Almost all samples were contaminated with fungi but only 4 feed samples showed aflatoxin concentration within the detection limit. Furthere experiments should be done on different liver samples in Qatar to chek the probability of this presence.
