Influence of Phytase on Tibia Bone Characteristics of Broiler Quail Fed on Corn-Soybean Meal Diets
BACKGROUND: Exogenous phytase enhances the utilization of plant phytate phosphorus in poultry. OBJECTIVES: In the present study the effects of exogenous phytase was investigated on tibia bone characteristics of white quail. METHODS: In a 2x2 factorial arrangement, eighty, 11-day old unsexed chicks were randomly divided into 4 treatments of 20 replicates. All birds received one of four experimen...
متن کاملEffect of enzyme supplementation of broiler diets based on corn and soybeans.
Digestibility of diets based on corn and soybean meal or soybeans treated by roasting or extrusion, with or without an enzyme supplementation, was measured by "true" (Sibbald) methods, by analysis of excreta, and by analysis of ileal digesta. Only analysis of ileal digesta was able to consistently measure differences between soybean and enzyme treatments in the digestibility of CP, starch, fat,...
متن کاملthe effect of multi enzyme supplementation to tomato pomace, as based on corn-soybean meal diets, on performance and carcass traits in broiler chicks
this experiment was carried out to study effect of supplementary multi enzyme (0, 4 gr per 100 kg of diet) to corn-soybean meal based diets with different levels of tomato pomace (tp, 0, 2, 4, 6 and 8 %, respectively) on chick performance and carcass traits. four hundred and eighty 480 day-old chicks (ross-308) were employed [four replicates (n=20)] in a completely randomized experimental desig...
متن کاملEffect of Using Enzyme Complex on Productivity and Hatchability of Broiler Breeders Fed a Corn-Soybean Meal Diet
A total number of 5520 female and 480 male breeders (Arbor Acres plus) at 42wks of age were used in a 10-week-trial to investigate the effect of an enzyme complex on the quality and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. There were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzy...
