Efficiency of feed additive based on liposomal beta-carotine in pig breeding

The article provides information on the study of the effectiveness of feed additives in pig breeding. Scientific and economic experience was carried out in the production conditions of the pig breeding farm of the Orel region in accordance with generally accepted methods of zootechnical research. As a result of the conducted studies, it was found that the use of the feed additive "LipoCar" in the diet of pigs contributes to the high safety of the young stock, more intensive growth and reduction of feed costs per 1 kg of live weight gain. Therefore, this feed additive, according to the author of the article, can be recommended for use in the technology of raising young animals and sows of the second half of pregnancy. One of the decisive factors in the intensification of the development of pig breeding, the full realization of genetic potential and productivity, reducing feed costs per unit of production, maintaining the natural resistance of the animal organism is a full-fledged balanced feeding. As a result of the conducted studies, it was revealed that the use of this additive at a dosage of 2.1 g per head contributes to an increase in multiple fertility by 4.8%, large-fruited by 20.0%, nest weight by 6.5% by 60 days of age and the safety of the young stock by 2.2%. The growth rate of young animals increases by 3.4-16.2% (p≤ 0.05).
