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.
