متن کاملThe Genetic Improvement of Carcass Composition in Beef Cattle
Although carcass trait selection programs have primarily focused on carcass marbling (quality grade), recent changes in the North American beef industry will very likely increase the economic importance of carcass composition (yield grade). Ultrasound technology is a valuable tool in these efforts. This review summarizes recent research pertaining to the role of ultrasound in improving carcass ...
متن کاملThe effect of cimaterol and its withdrawal on carcass composition and meat tenderness of broiler chickens.
To examine the effects of cimaterol (CIM) and its withdrawal on meat tenderness and carcass composition, 21-d-old broiler chickens (n = 288) were randomly assigned to one of nine treatments. For Treatments 1 through 6, birds were fed a control diet or a diet containing 1 ppm CIM until slaughter at 35, 42, or 49 d of age. Treatments 7 and 8 consisted of birds fed the CIM diet for 14 d and then w...
متن کاملGenetic and Sex Differences in Carcass Traits of Nigerian Indigenous Chickens
Genetic and sex differences or variation in carcass characteristic and slaughter yield were studied using a total of 150 intensively reared and clinically normal chickens consisted of 50 each of normal feather, naked neck and frizzled matured chickens genotypes. The result showed that genotype as well as sex have significant effect (P<0.05) on carcass characteristics and slaughter yield at twen...
متن کاملResponse time of broiler chickens to cimaterol: meat tenderness, muscle composition fiber size, and carcass characteristics.
The response time to cimaterol (CIM), a beta-adrenergic agonist, by broiler chickens for carcass characteristics, muscle composition, muscle fiber size, catheptic enzyme activity, and tenderness was determined. Two trials were conducted in which chickens were fed a control diet (CON) containing 0 ppm of CIM or a diet containing 1 ppm of CIM. Trial 1 consisted of 55, 31-d-old broiler chickens in...
