Purpose. To study the effect of feeding young guinea fowl and geese with a biologically active additive in the composition of compound feeds on their growth rate, feed consumption and livestock survival. Methods. Analytical methods of research, observation, comparison, analysis, zootechnical experiment. Results. According to the results of research on young guinea fowl and geese, it can be stated that the biological additive of the proposed composition has a positive effect on the living organism and stimulates it to increase growth rate, which is manifested in an increase in average daily gains, a decrease in feed consumption and livestock survival. In the goslings of the experimental group, which received a biologically active additive during the experiment, the livestock was completely preserved. The survival of the birds in the control group was lower by 10.0%. The highest average daily gain was observed in the goslings of the experimental group. It was 62.4 g, which is 7.0% more compared to the birds of the control group. Feed consumption per 1 kg of gain in the goslings of the experimental group was lower compared to the control group by 6.4%. The use of a biologically active additive contributed to an increase in the average daily gains in young guinea fowl during the experimental period by 5.2%. And feed consumption per 1 kg of gain compared to the birds of the control group was lower by 9.1%. Conclusions. Adding 1% of a biologically active additive to the composition of the compound feed for goslings contributes to a decrease in feed consumption per 1 kg of gain in the goslings of the experimental group by 6.4%, an increase in their live weight, compared to the initial one, by 16.6 times and in the experimental ones - by 17.7 times. The use of a biologically active additive in the composition of starter and grower compound feeds contributed to an increase in the average daily gains in young guinea fowl during the experimental period by 5.2%.
