Abstract

In a scientific and economic experiment, it was studied the effect of the multifunctional probiotic preparation Bionorm K on the stabilizing digestion process and dairy cow milk productivity-increasing during the transition from one ration composition to another.
The probiotic drug Bionorm K is a multi-strain product, which consists of 14 strains of bifidobacteria and lactobacillus. Moreover, it has a protective shell, which retains the microorganism activity after passing the acid barrier of the cow’s abomasum.
It was found that the diet probiotic addition is advisable to start from the first day after calving and continues for 45 days in a dose of 5 g per head per day.
The experimental group animals outpaced the control animals by the consumption of dry matter of the diet by 2.6 %. At the same time, the likelihood of developing digestive disorders and the incidence of diarrhea is reduced by 2-2.5 times. At the end of the studies, none of the cows suffered from digestive upsets.
Besides, cows, which injected the probiotic to the ration, had improved the ruminative processes due to an increase in the frequency of their contractions compared to the control. Already on the fifth day, the number of ruminal contractions at the experimental animals was 12.5% higher than the control. The higher intensity of rumen work at the experimental cows was maintained during the entire time of probiotic addition into the diet, although the difference with the control was constantly decreasing.
The feed probiotic addition promotes a gradual increase in milk production by 7.64 % and an increase in the fat level in milk by 0.02 % compared to the control. At the same time, feed costs of 1 kg of milk decreased by 5.6 %.
The probiotic stabilizes the biochemical composition of the cow blood quickly and increases the gamma globulin level at blood serum, which indicates an increase in the immune status of cows in the experimental group.
