Anthropologist Steve Striffler begins this book in a poultry processing plant, drawing on his own experiences there as a worker. He also reports on the way chickens are raised today and how they are consumed. What he discovers about America's favorite meat is not just unpleasant but a powerful indictment of our industrial food system. The process of bringing chicken to our dinner tables is unhealthy for all concerned-from farmer to factory worker to consumer. The book traces the development of the poultry industry since the Second World War, analyzing the impact of such changes as the destruction of the family farm, the processing of chicken into nuggets and patties, and the changing makeup of the industrial labor force. The author describes the lives of immigrant workers and their reception in the small towns where they live. The conclusion is clear: there has to be a better way. Striffler proposes radical but practical change, a plan that promises more humane treatment of chickens, better food for the consumer, and fair payment for food workers and farmers.

InThe Chicken Trail, Kathleen C. Schwartzman examines the impact of globalization-and of NAFTA in particular-on the North American poultry industry, focusing on the displacement of African American workers in the southeast United States and workers in Mexico. Schwartzman documents how the transformation of U.S. poultry production in the 1980s increased its export capacity and changed the nature and consequences of labor conflict. She documents how globalization-and NAFTA in particular-forced Mexico to open its commodity and capital markets, and eliminate state support of corporations and rural smallholders. As a consequence, many Mexicans were forced to abandon their no longer sustainable small farms, with some seeking work in industrialized poultry factories north of the border. By following this chicken trail, Schwartzman breaks through the deadlocked immigration debate, highlighting the broader economic and political contexts of immigration flows. The narrative that undocumented worker take jobs that Americans don't want to do is too simplistic. Schwartzman argues instead that illegal immigration is better understood as a labor story in which the hiring of undocumented workers is part of a management response to the crises of profit making and labor-management conflict. By placing the poultry industry at the center of a constellation of competing individual, corporate, and national interests and such factors as national debt, free trade, economic development, industrial restructuring, and African American unemployment,The Chicken Trailmakes a significant contribution to our understanding of the implications of globalization for labor and how the externalities of free trade and neoliberalism become the social problems of nations and the tragedies of individuals.

Chicken coccidiosis is an economically significant disease of commercial chicken industry accounting for losses of more than £10.4 billion (according to 2016 prices). Additionally, the costs incurred in prophylaxis and therapeutics against chicken coccidiosis in developing countries (for instance Pakistan according to 2018 prices) reached US$45,000.00 while production losses for various categories of chicken ranges 104.74 to US $ 2,750,779.00. The infection has been reported from all types of commercial chickens (broiler, layer, breeder) having a range of reported prevalence of 7–90%. The concern of resistance towards major anticoccidials has provided a way forward to vaccine research and development. For prophylaxis of chicken coccidiosis, live virulent, attenuated, ionophore tolerant strains and recombinant vaccines have been extensively trialed and commercialized. Eimeria antigens and novel vaccine adjuvants have elicited the protective efficacy against coccidial challenge. The cost of production and achieving robust immune responses in birds are major challenges for commercial vaccine production. In the future, research should be focused on the development of multivalent anticoccidial vaccines for commercial poultry. Efforts should also be made on the discovery of novel antigens for incorporation into vaccine designs which might be more effective against multiple Eimeria species. This review presents a recap to the overall progress against chicken Eimeria with particular reference to previous decade. The article presents critical analysis of potential areas for future research in chicken Eimeria vaccine development.

Genetically, modern broilers are fast-growing birds which attain the market age at the age of 5 weeks. To maintain optimum production, antibiotics have been commonly included in the diets as growth promoters. However, due to the increase in antimicrobial resistance, their uses have been banned worldwide. To keep the optimum level of production and health in broiler industry, the use of alternative growth promoters such as probiotics, prebiotics, enzymes, and organic acids has been proposed. Chemically, organic acids are weak acids and only partially dissociate. They are considered safe and have been used for preservation of food for centuries. Nowadays, organic acids have been reported for antibacterial, immune potentiating, and growth promoters in broilers. In this review, the effects of dietary inclusion of organic acids on growth, nutrient digestibility, intestinal integrity, immune system, and antibacterial activity in broilers are discussed.

The demand for chicken meat is on the rise, necessitating high level of production and efficient feed conversion which to a certain extent can be actualized by the use of specific trace minerals like zinc (Zn). Zn is a part of several enzymes involved in the metabolism of protein, fat, carbohydrates, and nucleic acids. In addition, Zn has antioxidant properties and is vital for hormone function, including growth, pancreatic, and sex hormones. Its deficiency in animals is characterized by poor fertility, decreased feed intake, poor growth, testicular atrophy, and weakened immunity. Nano-Zn sources have been shown to be more bioavailable than conventional zinc (organic and inorganic) sources. Zn from organic sources, on the other hand, has higher bioavailability than Zn from inorganic sources. Furthermore, Zn supplementation promotes growth, enhances antioxidant capacity, modulates the immunity, and improves health indices in broiler chickens. Published studies have demonstrated that Zn supplementation has the potential to improve carcass yield and meat quality in broilers with various research contradictions. However, a clear understanding of the role of Zn in broiler nutrition is still lacking, necessitating further research. As a result, the purpose of this review was to highlight the influence of Zn (organic or inorganic) supplementation on growth, blood characteristics, antioxidant status, immune responses, Zn tissue/fecal concentrations, intestinal villus histomorphology, and meat quality of broiler chickens as well as Zn bioavailability to understand the role of Zn in broiler nutrition, resolve contradictory research results, and identify knowledge gaps. Understanding the role of dietary Zn in broiler chicken nutrition and meat quality will avail important suggestion on policy advancements and sustainable use of Zn in the broiler chicken industry.

United States is the largest producer and the second largest exporter of broiler meat in the world. In the US, broiler production is largely converting to antibiotic-free programs which has caused an increase in morbidity and mortality within broiler farms. Escherichia coli and Clostridium perfringens are two important pathogenic bacteria readily found in the broiler environment and result in annual billion-dollar losses from colibacillosis, gangrenous dermatitis, and necrotic enteritis. The broiler industry is in search of non-antibiotic alternatives including novel vaccines, prebiotics, probiotics, and housing management strategies to mitigate production losses due to these diseases. This review provides an overview of the broiler industry and antibiotic free production, current challenges, and emerging research on antibiotic alternatives to reduce pathogenic microbial presence and improve bird health.

Background Avian infectious bronchitis (IB) is a highly contagious respiratory disease that affects the poultry industry globally. The disease is caused by avian infectious bronchitis virus (IBV), member of the genus Gammacoronavirus . In Ethiopia, IBV has been reported in both commercial and backyard chickens based on clinical observation. The objectives of this study were to isolate the virus, conduct molecular based identification, and phylogenetic analysis of the circulating IBV isolates. Methods and materials A cross-sectional study was conducted between November 2023 and May 2024 in Mekele and Bishoftu, Ethiopia. A total of 49 clinical samples were collected, comprising 12 tissue samples and 39 pooled swab samples. Of these, 6 samples—specifically, 5 swab samples and 1 tissue sample—tested positive for infectious bronchitis virus (IBV) through virus-specific conventional RT-PCR and real-time PCR. Nested PCR was performed using serotype-specific primers. The purified PCR products, which targeted the spike glycoprotein S1 subunit gene and the 3′ UTR of the IBV, were sequenced, followed by phylogenetic tree analysis. Results The six positive samples propagated into specific pathogen free embryonated eggs and exhibited characteristic IBV lesions and mortality observed over five consecutive passages. IBV isolates from Bishoftu ( n  = 4) and Mekele ( n  = 2) were amplified using one-step RT-PCR to target 466 bp of the S1 subunit gene and 433 bp of the 3ʹUTR. A BLAST search on the S1 partial gene and 3ʹUTR sequences, nested PCR, and phylogenetic analysis revealed that the present IBV isolates are genetically similar to the Massachusetts serotype. The S1 gene sequences of the five IBV isolates were deposited in GenBank with accession numbers PQ389500 to PQ389504. Conclusions This is the first detailed study on IB virus isolation, molecular detection, sequencing, and phylogenetic analysis in Ethiopia. The findings revealed that the outbreaks were caused by the IB virus, which created a serious health risk and economic losses in the chicken industry. To the author’s knowledge, this is the first comprehensive study on the isolation and genetic analysis of IBV in Ethiopia. Further research on the economic impact of IBV in chicken production, farm biosecurity, serotyping of circulating IB virus, and vaccine development based on the local serotypes is recommended.

Beginning in 2003, the USDA’s Food Safety and Inspection Service (FSIS) put forth a series of Federal Register announcements regarding the public disclosure of results of tests for Salmonella in chicken carcasses. In particular, FSIS suggested in 2003 that it might disclose the identities of any slaughter or ground meat plant failing its Salmonella tests if test performance did not improve, and in 2004 the service increased regulatory scrutiny of plants not meeting FSIS Salmonella standards. In 2006, FSIS introduced a more easily-understood measure of food-safety quality and indicated that public disclosure would be forthcoming if results of tests for Salmonella did not improve; FSIS targeted the chicken-slaughter industry with a high degree of specificity. In 2008, FSIS began reporting the names of chicken-slaughter plants with poor performance on tests for Salmonella in chicken carcasses. This article examines the effects of these regulatory actions on Salmonella test outcomes. We find that (1) announcements in 2003 and 2004 were associated with improved performance by the poorest-performing chicken-slaughter plants; (2) the introduction of an easily-understood measure of food-safety quality and the threat of disclosure of the identities of poorly performing plants in 2006 were associated with improved performance by all chicken-slaughter plants; and (3) implementation of a public disclosure program in 2008 was associated with improvements among better-performing chicken-slaughter plants.
