Abstract

5 groups were formed from quails of the Manchurian breed. The control group - the main diet, and the experimental ones were given 0.25% (1 experimental group (EG)); 0.5% (2EG); 0.75 (3EG) and 1% (4EG) Baikal EM-2 solution at the rate of 3 ml per head. Histological studies were performed at the age of 147 days. Egg production per average laying hen in the experimental groups was on average 11.7% higher compared to the control group, the average live weight of quails in the experimental groups is 1.2% higher. In the duodenum, in all experimental groups, there was a better development of villi by 19.8-58.6% (P≤0.001), and in the skinny, the height of the villi was significantly higher in EG1, EG2, and EG4 by 19%-48%. The crypt layer significantly increased in the duodenum of 4EG by 13.9% (P≤0.05). The muscular elements of the duodenum were better developed in the experimental groups. In the cecum, the size of the layers did not differ. We assume that the experienced bird achieved high zootechnical results due to the better development of the villi of the small intestine.
