The effect of date fibre supplemented with an exogenous enzyme on the performance and meat quality of broiler chickens

摘要: 1. Two experiments were conducted to evaluate the use of date fibre as a partial replacement maize source energy for growing broiler chicken. In experiment 1, was given alone determine apparent metabolisable (AME) and ileal digestibility amino acids crude fibre. 2. Date had lower AME content (8·7 vs 13·6 MJ/kg) coefficients dry matter (0·35 0·83), (0·20 0·54) acids. 3. Based on results growth study test effect exogenous enzymes nutritive value (experiment 2). 4. Three contents (5, 10 15%) with without enzyme supplementation evaluated. Daily feed intake, body weight gain conversion ratio measured. At end 2, 160 birds randomly selected slaughtered carcase meat quality traits well measuring viscosity. 5. Substitution by a...
