INFLUENCE OF HUMIC ADDITIVE ON PRODUCTIVE INDICATORS AND BODY CHEMICAL COMPOSITION OF BROILER CHICKENS

Abstract

This study was devoted to assessing the effect of a feed additive based on humic substances on the body of broiler chickens. The broilers were divided into two groups of 10 heads each, and throughout the experiment were in the same conditions of keeping and feeding. Chickens of the experimental group were added to the basic diet with the feed additive "Fulvohumate Ivan Ovsinsky" (Russia), 0.01 ml per 1 kg of live weight. The duration of the experiment was 42 days. The study revealed that the additive based on humic substances has a stimulating effect on the productive and slaughter performance of broiler chickens, in particular, it increases the live weight by 22.91% (P?0.05), while reducing feed costs per 1 kg of live weight gain by 8.83%. Humic substances contribute to the transformational distribution of nutrients in the intestine, which is reflected in the chemical composition of the body, as well as individual tissues and organs of broiler chickens, including an increase in the concentration of protein and fat in the carcass pulp by 2.5 % and 0.7% in comparison with control. Based on the study, it was found that this humic supplement can be used in the cultivation of broiler chickens in order to increase productivity and reduce economic costs.
