Effectiveness of the influence of biopreparations based on bacteria of the genus Bacillus in the technology of growing of weaning pigs

Correct and full-fledged feeding of weaned piglets is the key to obtaining high performance indicators in growing and fattening. Parameters such as the rate of growth and development, the deposition of nutrients in the carcass, the development of the digestive system differ significantly depending on age and live weight. Weaning pigs are especially sensitive to any change in diet. In this regard, balanced and high-quality feeding of piglets in the early rearing periods must meet the current needs of the body in order to ensure maximum productivity. Probiotics, used as prevention and treatment of gastrointestinal diseases, are also used as growth stimulants. In the presented study, the use of spore-forming probiotics "Biosporin" and "Bacell" on the growth performance of weaned pigs was studied. The results showed that the use of both drugs significantly accelerated the growth rate of the animals. Thus, the live weight of piglets in the experimental groups at the end of the experiment exceeded the control by an average of 8%, which indicates the effective action of the additives.
