Strain and sex effects on ascites development in commercial broiler chickens
The objective of this study was to assess the importance of strain and sex and their interaction effect on broiler chickens’ performance and susceptibility to ascites. Chicks from three strains (Ross 308, Cobb 500 and Arian, labeled as A, B and C respectively) were obtained from the same age breeder and sexed when one-day-old. Each crosses’ sex was assigned to four pens of 60 broilers each. Bod...
متن کاملEffects of Dietary Octacosanol on Growth Performance, Carcass Characteristics and Meat Quality of Broiler Chicks
Octacosanol, which has prominent physiological activities and functions, has been recognized as a potential growth promoter in animals. A total of 392 1-d-old male Arbor Acres broiler chicks with similar body weight were randomly distributed into four dietary groups of seven replicates with 14 birds each supplemented with 0, 12, 24, or 36 mg octacosanol (extracted from rice bran, purity >92%)/k...

متن کاملGenetic and environmental effects on meat quality.
In order for livestock industries to consistently produce high quality meat, there must be an understanding of the factors that cause quality to vary, as well as the contribution of genetics. A brief overview of meat tenderness is presented to understand how genotype and environment may interact to influence this trait. Essentially, meat tenderness is determined from the contribution of connect...
متن کاملCharacteristics of pale, soft, exudative broiler breast meat.
The objective of the study was to characterize pale breast meat, compare it with normal colored breast meat, and determine whether it should be considered pale, soft, and exudative (PSE). Characteristics of 20 normal and 20 pale broiler breasts, obtained at a commercial slaughter plant, were evaluated. Compared with normal meat, the pale breast meat had a significantly (P < 0.05) lower pH (5.7 ...
