Amino acid preparations in feeding young pigs and laying hens

Abstract

Abstract The paper deals with the effectiveness of the drug “L-lysine monohydrochloride feed”. Animals of the experimental group additionally included in the main diet of 2.5% L-lysine monohydrochloride feed by weight of concentrates. The inclusion of the studied additive in the diets of young pigs contributes to an increase in the average daily gain of 14.1%, reducing the cost of feed by 11.73% compared with the control group. As a result of the research it was found that due to the use of the drug L-lysine monohydrochloride feed, an additional 3.38 kg gain per head or 253.5 rubles was obtained. During the study on laying hens aged 25 to 33 weeks, egg production was studied, which by the end of the experiment was: 93.7% in the control group, 95.2% in the experimental, which is 1.5% more. In addition, there is a tendency to increase egg weight by 1 g or 1.8%, yolk weight and its specific weight in the egg by 2 g or 13.3%, respectively, as well as thickening of the shell by 3 microns or 8.1%, and a decrease in shell content by 1%.
