Abstract
This article presents the results of a study of the amino acid and microelement composition of eggs of laying hens of the egg direction of the Hisex Brown cross when using the Abiotonik feed additive at a dose of 1 ml/kg of body weight every other day. It was found that in the eggs of laying hens of the experimental group, the content of nonessential amino acids increased by 12,3 %, partially nonessential amino acids – by 13,3% and irreplaceable – by 14,7% as compared to the control group. In addition, in the eggs of laying hens of the experimental group, the content of selenium (Se) and iron (Fe) is 59,3 % and 40 % higher, respectively, compared to the control group. As a result of the study of the effect of this feed additive on the egg productivity of laying hens, it was found that the weight of eggs of birds in the experimental group increased by an average of 1,1 g, and egg production over a period of 7 days (44th – 51st days of the experiment) increased by 15 eggs compared to the control group.
