The authors proposed the use of the probiotic "Subtilis" to the ducklings of the experimental group, which allowed them to have a greater increase in body weight throughout the experiment compared to the analogues of the control group. The greatest increase in body weight was observed when weighing a poultry at the age of 36,44,50 days and during these periods it was on average higher by 106.5 g in the experimental groupcompared to the control group. Over the entire period of growing, the dynamics of the body weight of the experimental group of ducklings was higher by 3.7 % from the analogues of the control group. The average daily body weight gain of ducks was 6.1 g (9.2%) more in the period from 16 to 22 days of growing in the experimental group than in the control group. The preservation of the experimental poultry population in the period from 1 to 50 days of life increased by 7%, the growing time was reduced by 4 days.
