Abstract
Pig breeding is one of the leading agricultural sectors that ensures the country’s food safety. In this regard, pig breeding must become a highly profitable branch of the agro-industrial complex due to growth of range of production performance indicators. Various feed additives are the reserve for increasing the productivity of the animals. The most popular feed supplements used today are probiotics and phytobiotics. Modern probiotic preparations are a complex (symbiotic additives) consisting of various strains of bacteria with addition of enzymes, prebiotics, chelating elements, amino acids and biologically active components. The article provides data on use of the probiotic preparation “Profort” and the phytobiotic “Intebio” in feeding of sows in farrow and nursing sows. According to the results of scientific and economic experience it was found that feed additives increased the following indicators: prolificacy — by 1.9–2.9%, size of the young piglets — by 10.4–12.3%, number of mature piglets in the litter — by 10.8–11.8%, rate of survival of the young piglets — by 4.0–6.1%, weight of the piglets litter by the moment of weaning — by 18.0–22.2%. The use of the preparations led to decrease in feed costs per 1 kg of liveweight gain and increased revenue obtained from the sale of the young livestock.
