USE OF IMMUNOTROPIC DRUGS IN REALIZATION OF REPRODUCTIVE POTENTIAL ОF YOUNG STOCK PIGS

Abstract

In the conditions of modern pig farming, the animal body experiences a high physiological load. Animals are constantly affected by various stress factors due to the peculiarities of the technology of maintenance. Since it is impossible to fully exclude the effect of stress factors, an important role in minimizing negative consequences is played by optimizing the conditions of housing, as well as increasing the resistance and ability of the animal organism to adapt. The purpose of this work is to realize the biopotential of the reproductive qualities of replacement pigs by the immune correction of the animal body with PigStim-V and PigStim-F preparations. For the experiment, 30 suckling pigs (females) were formed into 3 groups of 10 animals each. The pigs of the 1st experimental group were injected intramuscularly the immunotropic preparation PigStim-V at a dose of 1 ml per head three times, on the 15th, 20th and 25th days of life. Pigs of the 2nd experimental group were injected the immunotropic preparation PigStim-F by the similar scheme. No immunotropic drugs were injected to pigs of the control group. Insemination of pigs was carried out in the 4th estrus, at the age of 7.5-8 months and at the optimal live weight. A positive effect of the immunotropic preparations PigStim-V and PigStim-F on the reproductive qualities of replacement pigs was revealed. In the experimental groups, an earlier start of estrus, a decrease in the age of the first insemination, and an increase in its effectiveness have been noticed. Against the background of immune correction, the rate of prolificacy increased, the stillbirth rate, and the index of incidence of postpartum diseases (MMA) decreased, the safety and growth rate increased; in sows, the period from weaning to the onset of the heat reduced.
