The role of correction of microflora of the genital tract of sows in the implementation of reproductive potential
The research is devoted to the study of the influence of probiotic preparation "Bioplus 2B" on the germ of the genital tract and reproductive health of sows. The experiments were carried out in the pig farm on 74 sows, on 108-110-day of pregnancy. The sows weredivided into three groups. The sows of the first group served as a control one. The sows of the second one within 14 days before weaning received probiotic preparation "Bioplus 2B" at a dose of 0.4 g/kg of feed, the third onereceived "Bioplus 2B" within 14 days before the farrow and during the last 14 days before weaning the sows received the same dose. The samples of vaginal swabs before the farrow were received from the animals, 14 days before weaning and on the day of weaning to determine the quantity and quality of microbiota. The indicators of the development and the survival of piglets, the onset of the sow reproductive cyclicism and indicators of impregnation capacity were considered. After prescribing the probiotic preparation "Bioplus 2B" the number of bifidobacteria, lactobacilli, enterococci, bacilli significantly increased and the content of lactic Escherichia, pathogenic staphylococci, yeast-like fungidecreasedin the genital tract of sows. After its single and double prescription on average, more piglets were taken to the nest than in the control respectively by 0.28 and 0.39 heads, which body weight was higher by 0.19 kg and 0.36 kg, safety - more by 4.6% and 6.7%. Sexual cyclicism in sows occurred earlier, respectively, by 0.31 and 0.61 days, latent endometritis manifested less often in 1.3 and 1.8 times, fertilization was higher by 2.4 and 6.1%. Thus, Bioplus 2B, normalizing colonization resistance of the genital tract, helps to increase the reproductive performance of the sows.
