The improving of broiler chickens growing efficiency

Abstract

Relevance Insufficient attention is paid to the practical use of enzyme preparations, although numerous studies have proven the effectiveness of these substances in the feeding of animals and poultry. Establishing the feasibility and effectiveness of the use of the enzyme preparation as part of animal feed for growing broiler chickens is an urgent task. Methods To conduct the experiment using the method of analog groups, 4 groups of broiler chickens (1 control and 3 experimental) of the COBB 500 cross-breed at a daily age of 100 animals (50 heads of males and 50 heads of hens) in each were formed. The experiments were carried out from daily from 35.7 to 36.3 days of age. Results Experimentally studied different doses of the multienzyme enzyme Axtra XAP 101 in the composition of feed and the optimum doses in the amount of 7-9% of the dry matter of feed. Multienzyme enzyme preparation Axtra XAP 101 effect on indices of meat productivity of broiler chickens. It is established that this preparation promotes increase of average daily gain, reduction of conversion of a forage and positively influences their safety.
