Realization of reproductive potential of sows against the background of probiotic preparations

In this work, a scientific and practical justification is given for the appropriateness of using probiotic preparations for the production and raising of piglets in order to achieve results in the field of reproduction of animals and stimulate the effect on the body's resistance in the biological chain "mother - fetus - newborn". It was found that the number of newborn piglets from sows of the first and second group experiments was 7.2 and 10.3 % more than in the control group, but the difference was insignificant (P> 0.05). The number of life opportunities obtained is 8.5 and 12.5 % (P 2 and Immunoflor in sow reproduction technologies, a decrease in piglets of 1.4 and 2.1 times, respectively. The new generation probiotic preparations tested by us for the first time, А2 and Immunoflor, were increased in terms of coarse sows' milk yield by 4.2 kg and 4.7 kgand fertility by 11.4 and 3.6 %. The results obtained include the fact that the probiotic preparations А2 and Immunoflor have a beneficial effect on the intrauterine development of the fetus, increasing the number of live piglets in the litter, increasing coarse fertility, and also improving the milk production of sows.
