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 کاملInfluence of Citric Acid and Microbial Phytase on Growth Performance and Carcass Characteristics of Broiler Chickens
Problem statement: The aim of this study was to investigated the effects of adding citric acid and microbial phytase supplementation (Natuphos) on growth performance and carcass characteristics of broiler chickens fed corn soybean meal base diets. Approach: The experiment included nine treatments with 10 birds in each replicate using a 3×3 factorial design for two main factors of citric acid (0...
متن کاملInfluence of calcium source and a novel microbial phytase on broiler performance and bone
Introduction The total dietary Ca requirement for broilers has previously been determined using limestone, monoor di-calcium phosphate, and in the presence of dietary phytate (Bar et al., 2003). Phytate has been reported to increase the total dietary Ca requirement of chickens from 0.50% to 0.95% (Nelson et al., 1968). The use of exogenous phytase promotes phytate hydrolysis and allows for a ma...
متن کاملThe influence of phytase enzyme supplementation on performance and calcium and phosphorus metabolism of broiler chicks
Two experiments were conducted to study the effect of phytase supplementation to lowphosphorus starter and finisher broiler diets on mineral utilization and growth performance. All diets in this study were isonitrogenous, isocaloric and corn-soybean diets. In Experiment 1, four replicate groups of 15 commercial broiler chicks, one-day old, were randomly assigned to each of two dietary treatment...
متن کاملInfluence of limestone and phytase on broiler performance, gastrointestinal pH, and apparent ileal nutrient digestibility.
An experiment was conducted to determine the influence of 2 levels of dietary Ca from limestone and 3 levels of phytase on broiler performance, bone ash, gastrointestinal pH, and apparent ileal digestibility (AID) of Ca, P, and amino acids. Cobb 500 broilers (n = 576) were allowed access to one of 6 corn-soy diets from 0 to 16 d. Experimental diets contained 1.03% or 0.64% Ca from limestone and...
