Digestability of nutrient of the diet when using the feed additive “Pulyar”

Abstract

This article presents the results of a study of the possibility of using the feed additive "Pular" in the ration of broiler chickens. As a result of the conducted studies to determine the digestibility of the feed additive "Pular" in broiler chickens of the «ROSS 308» cross, it was found that at the age of 27 and 34 days, the poultry of the II and III experimental groups exceeded the control group almost in all indicators of the digestibility of the feed. The coefficient of digestibility of crude protein was higher in broiler chickens of the II and III experimental groups by 4.13-4.92%, fiber by 1.61 - 2.68%, ash by 85.55 - 97.71% and nitrogen-free extractive substances by 1.58 - 2.28 compared with the control group. In the conclusions based on the analysis of the conducted studies, the authors conclude that the inclusion of the feed mixture "Pular" in the ration contributes to a better assimilation of nutrients in the poultry body, as well as the efficiency of feed using, that contributes to increase of the growth rate of broiler chickens in turn.
