Abstract

Our studies have shown that additional introduction of feed additive “Elevit” into the rearing gilts’ diet at a dosage of 1.0; 1.5; 2.0% during their breeding from 4 to 8 months allows to increase the gilts’ live weight by 3.9; 7.0; 9.5%, respectively, with average daily gains also increasing in comparison to the control group by 6.4; 11.6; 15.7%. Also, when reaching 8 months, gilts of experimental groups exceeded their peers from the control group in heart mass by 3.2; 4.1; 6.3%; lungs - by 3.7; 4.0; 4.2%; liver - by 5.1; 5.8; 6.2%, respectively. When rearing gilts reached the age of 8 months, a study of their reproductive function was carried out. So, we have established that gilts receiving “Elevit” feed additive together with the diet at a dosage of 1.0; 1.5; 2.0% exceeded their peers from the control group in fertilization indicator by 4.5; 5.4; 5.4%, and multifertility - by 4.3; 6.2; 7.5% respectively. The increase in these indicators led to an increase in the total number of experimental piglets received from rearing sows by 36, 3; 47.1; 48.7% compared to control.
