Efficiency of using chitosan complex in feeding technology for broiler chickens under conditions of increased stocking density
Abstract
The purpose of the research was to determine the effectiveness of using the chitosan complex “KX-1” in the technology of feeding broiler chickens under conditions of increased stocking density of 23.5 birds/m². Broilers of the 1st control group received feed with standard nutritional value; broilers of experimental groups 2-4 were additionally introduced to a similar diet with a chitosan complex at the rate of 50, 70 and 100 g/t throughout the entire growing period. It was found that the highest efficiency of growing broiler chickens was in the 3rd experimental group, which received the chitosan complex “KX-1” at the rate of 70 g per 1 ton of feed. At 39 days of age, the chickens of this group in live weight exceeded their peers from the control group by 3.5%, from the 2nd experimental group - by 1.9%, and from the 4th experimental group - by 1.2%. The European productivity index in the 3rd experimental group was 9-20 units. (2.3-5.3%) higher than in other groups. The chitosan complex “KX-1” had a positive effect on the zootechnical parameters of poultry rearing under conditions of increased stocking density at a broiler factory and is a valuable feed additive for broilers.
