The aim of the study was to study the effect of diets using the potentially probiotic drug Bacillus amyloliquefaciens KB54 as part of compound feed (the rate of administration is 0.1% of the total diet, the content of viable spores in the final product is 10 6 CFU/g) in the diets of laying hens of the Dekalb cross. In the course of the study, it was established that the viability indicators of laying hens were at a high level and the safety of livestock in the studied groups during the period of the experiment was 100%; egg production in the experimental group was 96.7%, which is 2.3% more than in the control group of laying hens; chickens in the experimental group exceeded the control in growth intensity, which affected an increase in live weight by 12.5%, or 188.5 grams, which is 1.7 percentage points or 25.2 grams more than in the control group; feed costs for 10 eggs and 1 kg of egg mass in the experimental group were 1.43 and 2.36 kg, respectively, which is 11.7 and 14.5% lower than the control values. In this regard, we recommend using the probiotic preparation Bacillus amyloliquefaciens KB54 in the diets of laying hens, introduced into the compound feed in the amount of 0.1% of the total diet with the content of viable spores in the final product 10 6 CFU/g.
