The aim of our study was to determine the prolonged delayed action of probiotic feed protection of the intestinal mucosa of cows in the period before fertilization for the manifestation of the productive potential of their daughters during the first lactation.
Analytical work was carried out during the 2016-2019 economic years, the experimental part of the study was carried out on the basis of a dairy complex-breeder of Ukrainian red dairy cattle (700 dairy heads), located in Odessa region.
The results of a scientific and industrial study of a number of indicators of productivity of replacement heifers / heifers / heifers of the Ukrainian red dairy breed showed that the use of the feed probiotic preparation "Veterinary Multibacterin Bs + La suspension - feed mixture" together with the main diet of mothers before artificial insemination gave a positive prolonged effect on the manifestation of the productive potential of their half-siblings. For standard lactation, first-calf heifers in the experiment had a higher milk productivity by 6.99 % (respectively: 8121 and 7540 kg per head, P <0.05). At the same time, the first-calf heifers of the experimental group had a more physiological term for the interstitial period, namely: 425.39 days, which was 56.28 days shorter than in the control and contributed to the profitability of production.
It has been experimentally established that probiotic protection of the intestinal mucosa of mothers cows has a positive effect on the quality of the offspring, which forms the next generation of the breeding herd.
