Improving the reproductive function of replacement and adult sows

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

Rearing gilts breeding with the introduction of “Elevit” feed additive into their diet

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
