Studies have shown that feeding the feed additive “Elevit” during the preparation of sows for insemination in a dosage of 1.0; 2.0; 3.0; 4.0% over the basic daily diet can increase estrum in replacement sows by 6.6; 20.0; 26.6; 26.6%, respectively, fertilization and prolificacy by 2.1; 5.3; 6.6; 6.6% and 1.0; 4.3; 7.6; 6.5%, respectively. Such a significant increase in the previously mentioned indicators also led to an increase in the total number of piglets by 13.5; 43.2; 60.8; 59.4%, respectively, while their cost at birth decreased by 11.5; 29.7; 37.4; 36.7% compared to the control group. Similar results were obtained from adult sows – estrum increased by 3.4; 10.0; 10.0; 10.0%, fertilization and prolificacy by 0.5; 5.0; 5.0; 5.0% by 0.9; 8.2; 8.2; 9.1%, respectively. At the same time, the total number of piglets at birth increased by 5.8; 28.7; 28.3; 29.1%. Their cost at birth decreased in comparison with the first control group by 5.2; 21.9; 21.5; 21.8%. From the data obtained by us, the best option for feed additive “Elevit” feeding both in terms of zootechnical and economic efficiency is – for replacement gilts in the amount of 3.0%; for adult sows – 2.0% over the basic daily diet for the period of preparation for insemination.
