PROBIOTIC PREPARATIONS USE IN PIG BREEDING
In many farms, the main cause of death of piglets are diseases associated with disorders of the gastrointestinal tract. Stress is also an integral factor affecting the health of animals. There are two types of stress: weaning piglets from the sow and changing the usual feed. In piglets, there is a violation of appetite, lethargy, but after a while, the animals tend to make up for the loss by eating food on an empty stomach, and therefore cannot fully assimilate it. The action of most of the used probiotic preparations, feed additives is aimed at increasing the nonspecific resistance of the body, increasing the average daily gain in live weight, which is very relevant today. In particular, the use of preparations "Bacell" and "Prolam" in the pig industry allows not only to reduce the death of piglets, but also to increase the average daily gain in their live weight. The essence of the method lies in the fact that these drugs are included in the main diet. They contain microorganisms that create a favorable microflora for the gastrointestinal tract, increase nonspecific immunity, which further positively affects the safety of animals, increases their productivity. When using the probiotic preparations "Prolam" and "Bacell", the increase in live weight increased both in the 1st and 2nd experimental groups in comparison with the control group by 9.30 and 12.03%, respectively. In the second experimental group, where the additive "Bacell" was used at a dose of 3.0 g/kg, the most intensive increase in the live weight of young pigs was recorded. In this group, it was higher than in animals of the control group, and amounted to 12.03% (P<0.01).
