【 摘 要 】

The study determined the effects of feeding reformulated diets with carbohydrase on broilers growth performance, carcass yield, gut parameters and income over chick and feed cost. A total of 180 day-old Cobb straight run broiler chicks were randomly assigned to: Treatment 1 as standard diet with local industry nutrient specifications, Treatment 2 as reformulated diets (-93kcal/kg and -1.5% digestible amino acids) and Treatment 3 as reformulated diets (-93kcal/kg and -1.5% digestible amino acids) with carbohydrase, each treatment diets had six replications with 10 birds. Results showed that birds fed with treatment 3 supported their growth and feed conversion as it was comparable to birds fed with treatment 1. Carcass yield of birds fed with diet 3 were comparable also with birds fed with other treatment diets. Feeding treatment diet 2 on birds caused an increase in relative weight of ceca but, a remarkable decrease in birds fed with treatment diet 3. Moreover, feeding reformulated treatment diets (diet2 and 3) resulted in lower relative size of the large intestine compared with birds fed with treatment diet1. The income over chick feed cost analysis showed the economic benefit of supplementation of carbohydrase in reformulated diets and has the potential for feeding broilers under circumstances that may be favorably influenced raw materials and their cost.
