The possible sources of Campylobacter spp. in poultry meat before slaughter were studied by examining samples of feathers, cloaca swabs, litter swabs, transport coops, rinse water from coop washing equipment, and chicken breast supports in the slaughter line just before stunning. The samples were collected from 8 broiler houses and from 8 different producers, from a poultry integration system i...
Avian leukosis viruses (ALVS) cause different types of tumours in poultry and can affect the health and egg production of the birds. To investigate the presence of the virus in chicken layer flocks in Shiraz, 222 egg albumen from local layer breeder (25 eggs), local layer grand parent (30 eggs), broiler breeder (60 eggs), commercial layer (46 eggs) and broiler grand parent (61 eggs) were tested...
Broiler chicken meat is a strategic commodity that growing rapidly. This product occupies the highest consumption rating of products. study examines factors broiler market integration in Indonesia. The data used secondary for monthly time series, which 72 months, period January 2015-December 2020. were analyzed using multiple linear regression analysis approaches. results show significant varia...
The aim of this study was to determine the blood and tissue concentrations profile and effect of tilmicosin on some hematological and biochemical parameters in broiler chicken. Fifty clinically healthy Hubbard chickens were orally administered 25 mg/kg BW of tilmicosin once daily for 5 consecutive days. Tissue residues of tilmicosin in slaughtered healthy chicken could not be detected by microb...
Serological Survey of Avian Metapneumovirus Infection in Broiler Breeder Chicken Farms in Tamil Nadu
Avian metapneumovirus (aMPV) is an important poultry pathogen causing an acute highly contagious upper respiratory tract infection in chickens leading to swollen head syndrome. The disease can cause significant economic losses in turkey and chicken flocks, particularly when exacerbated by secondary pathogens. The purpose of this study was to determine the prevalence of avian metapneumovirus ant...
The aim of the study was to determine co-occurrence of Marek's disease virus (MDV) and chicken parvovirus (ChPV) co-occurrence in field chicken flocks. The materials for the study derived from 115 broiler chickens or layer hens originated from 23 farms with suspicion of Marek's disease (MD). Dual infection with MDV and ChPV was found in 23 (20%) examined chickens. The results obtained suggest a...
The genetic networks that govern the differentiation and growth of major tissues of economic importance in the chicken are largely unknown. Under a functional genomics project, our consortium has generated 30 609 expressed sequence tags (ESTs) and developed several chicken DNA microarrays, which represent the Chicken Metabolic/Somatic (10 K) and Neuroendocrine/Reproductive (8 K) Systems (http:/...
Heterophil chemotaxis, in response to chemotactic factors generated by three different strains of staphylococcal bacteria, was measured using the modified Boyden-chamber technique. Heterophils were obtained from healthy 6-to-8-week-old broiler chickens. Each bacterial strain generated factors that were chemotactic for chicken heterophils. Factors generated by two pathogenic isolates of Staphylo...
A 49-d feeding study evaluated whether standard broiler diets prepared with Syngenta Seeds VIP3A transgenic derived corn grain had any unanticipated adverse effects on male or female broiler chickens as compared with diets prepared with nontransgenic (isoline) control corn grain. Two commercial lots of grain grown in North Carolina during the 1999 (NC 1999) and 2000 (NC 2000) seasons were inclu...
Penicillic acid (PA), a mycotoxin, was originally isolated from the cultures of Penicillium puberulum. The present study was undertaken to find out the sublethal effect of penicillic acid mycotoxicosis on growth rate and immune status of broiler chicken. Forty eight day-old broiler chicks were randomly allotted to four groups of 12 birds each and fed with 0, 7.5, 15 and 30 ppm of penicillic aci...
