abstract: the extreme polymorphism in mhc b-f genes enables the chickens to recognize enormous numbers of foreign peptides to trigger an immune reaction. study of this genetic resources is very important and it is essential to avoid the loss of genetic variability. genetic polymorphism among arian strain, a endogenous broiler chickens in iran, was investigated. in this study pcr-sscp was carrie...

The Effect of Different Energy Level on Blood Metabolites, Bacterial Population Small Intestine and Performance Arian Broiler Chickens

background: inclusion of antioxidant sources in feed or water reduces the detrimental effects of free radicals and increases the antioxidative potential and stability of lipids in heat stressed broiler chicken. objectives: this study was conducted to examine the effect of satureja khuzistanica essential oils (skeo) on early postmortem and ultimate ph as well as antioxidative potential of breast...

The purpose of this study was to investigate the biological and genetic characterization of persistent Salmonella isolates in an integrated broiler chicken operation, in an attempt to elucidate the source of contamination. From the breeder farm, the hatchery, the broiler farm and the chicken slaughter house of an integrated broiler chicken operation, a total of 6 serotypes were observed. Althou...

A lower price on poultry meat, compared with other meats (beef, pork etc.), affects the increasing demand for poultry meat. The productivity and production cost of broiler chickens are directly related to the amount of feed fed, the proportion of crude protein in the feed, and the biological value and price of the feed. The EU produces only 30% of the protein crops used for feed; thus, the larg...

We examined 29 isolates of Salmonella enterica subspecies enterica serovar Schwarzengrund from broiler chickens (n=19) and retail chicken meats (n=10) in Japan for antimicrobial susceptibility and pulsed-field gel electrophoresis (PFGE) profiling. All isolates exhibited resistance to both bicozamycin and sulfadimethoxine (minimum inhibitory concentration of both antimicrobial agents: >512 micro...

A cross-sectional study was performed to estimate the prevalence of Salmonella on retail market chicken carcasses in Colombia. A total of 1,003 broiler chicken carcasses from 23 departments (one city per department) were collected via a stratified sampling method. Carcass rinses were tested for the presence of Salmonella by conventional culture methods. Salmonella strains were isolated from 27...

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...
