Productive and weight indicators of the digestive canal organs of broiler chickens when using a feed additive based on humic acids

Abstract

Relevance. Recently, a promising alternative to antibiotics has become a wide range of feed additives of different composition and different origin, the action of which is aimed at improving the safety of livestock, increasing live weight gain, feed conversion and the quality of the products obtained. One of such feed additives is «Reasil® Humic Health» based on humic acids.Methods. The production experience was carried out on the basis of the poultry farm of LLC «Vremya-91». To conduct production experience on broiler chickens of 21-day-old «Cobb 500» cross, according to the principle of analogues, 2 groups of poultry were formed: control and experimental, with 18,000 heads each. The bird of the control group received the main diet. Broiler chickens of the experimental group, in addition to the main diet, received the feed additive «Reasil® Humic Health» in a concentration of humic acid salts of 2 g/kg of feed.Results. The addition of a humic biologically active feed additive to the diet at a dose of 2 g/kg of feed makes it possible to increase the live weight of broilers by 9.5%, the safety of livestock by 2% and average daily gains by 21%.
