BACKGROUND From 2014 to 2015 in China, many broiler breeder and layer hen flocks exhibited a decrease in egg production and some chickens developed hepatitis syndrome including hepatomegaly, hepatic necrosis and hemorrhage. Avian hepatitis E virus (HEV) and avian leucosis virus subgroup J (ALV-J) both cause decreasing in egg production, hepatomegaly and hepatic hemorrhage in broiler breeder and...

The effect of ochratoxin A (OA) on the body weight, feed intake, and feed conversion was investigated in broiler chicken fed dietary levels of OA at 0, 1, and 2 ppm for 28 days from hatch. Feeding OA significantly reduced the growth rate of broiler chicken. The reduction was observed from the first week onwards in OA-treated groups. Feed consumption and feed conversion also showed a diminishing...

3.1 ABSTRACT A randomized complete block design with four treatments (100% pale, soft, and exudative (PSE), 100% PSE + 1.5% chicken collagen, 100% normal, and 100% normal + 1.5% chicken collagen) and six replications was utilized to test the effects of raw material and chicken collagen on protein functionality in the formulation of chunked and formed broiler breast. Addition of 1.5 % chicken co...

The objective of the experiment was to define if in ovo injection of acetylsalicylic acid (ASA) during the final stage of embryogenesis has an effect on morphotic parameters and heart work of chicken embryos subjected to hyperthermia. Eggs (n=420) from a broiler breeder flock were incubated under standard conditions. On the 18 d of incubation, they were injected with 5 mg of ASA/50 μl of 0.9% N...

1,001 faecal samples were obtained from 89 sheep (lambs and adult), 184 goats, 190 horses, 178 rabbits, 110 camels, 200 broiler chicken and 50 turkeys housed in farms from different localities in Tunisia. All samples were analysed for Cryptosporidium oocysts by microscopic examination of smears stained by modified Ziehl Neelsen technique. The parasite was detected in ten lambs and adult sheep (...

Effects of low-density broiler breeder diets on offspring performance and mortality were studied using 2,100 female and 210 male Cobb 500 breeders. Breeder treatments involved 4 experimental groups and a control group with normal density diets (ND, 2,600 kcal of AME/kg during rearing and 2,800 kcal of AME/kg during laying). In treatment 2, nutrient densities were decreased by 12% (LD12) and 11%...

This study was conducted to evaluate the long-term effects of in ovo injection of nano-silver, thyme and savory extracts in broiler breeder eggs on growth performance, lymphoid organ weights, immune and blood parameters and bone mineral concentration of broiler chicks. A total of 560 fertilized broiler breeder eggs were divided into 7 groups. On d 5 of incubation, eggs were treated with the fol...

This research was aimed to study and analyze the costs, revenues, profits of meat chicken breeding projects. The also estimating random frontier profit function, inefficiency function efficiency which based on cross-sectional data that included 59 projects for raising poultry in Waist governorate 2020.The results analysis showed through descriptive cost structure that, costs chicks fodder accou...

Listeria species are widely distributed in environment and L. monocytogenes are the causal agent of Listeriosis, the disease that can be serious and fatal to human and animals. The objectives of this study were to detect, isolate and identify Listeria monocytogenes from retail broiler chicken ready to eat meat products in restaurants-Khartoum state, Sudan. A total of 250 retail broiler chicken ...
