Increasing dietary lysine increases final pH and decreases drip loss of broiler breast meat.
Responses to increased dietary Lys concentrations were evaluated on 1,584 Ross 308 male broilers between 21 and 42 d of age housed according to 2 bird densities. The experimental design was composed of 8 factorial treatments: 2 bird densities (22 or 44 broilers/ 1.7 m(2) pen) x 4 true digestible (TD) Lys levels (0.83, 0.93, 1.03, and 1.13%). There were 6 repetitions per treatment. Birds were we...
متن کاملDietary glycine needs of broiler chicks.
Dietary Gly might become a limiting factor in all-vegetable diets fed to broiler chicks when low CP is formulated in combination with marginal levels of dietary Thr and Ser. A study was conducted to evaluate dietary Gly needs of broiler chicks. Day-old Ross 508 male chicks were placed in 32 floor pens (15 chicks/pen). Chicks were fed a common prestarter diet from 0 to 7 d of age and then fed a ...
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 کاملEffect of Dietary Chromium Yeast on Thigh Meat Quality of Broiler Chicks in Heat Stress Condition
This experiment was conducted to investigate the effect of different levels of dietary chromium yeast (Cr-yeast) on thigh meat quality of broiler chicks reared under heat stress condition. Two hundred and forty Ross male chickens in heat stress condition (33±3°C) were allocated to five treatments in a completely randomized design. Treatments were supplemented with 0 (control), 200, 400, 800 and...
متن کاملGrowth Traits, Breast Meat Yield and Quality of Broiler Genotypes under Hot Conditions
The study evaluated the body weight during growth (BWG), body weight at slaughter (BWS), breast meat yield (BMYg), percent breast meat yield (BMY) and breast meat quality (colour and drip loss) of genetically featherless (scsc) broilers compared to their feathered sibs under hot conditions. Two hundred featherless chicks and 200 feathered sibs were reared under hot conditions in two rooms (aver...
