Feeding of feed additives requires a rational system of use taking into account the peculiarities of cattle breeding.
When analyzing the results of studies, the feed additive Immunobacterin-D with the content of Sacharomyces cerevisiae 2 × 109 CFU / g are characterized by a positive effect on the body of animals. In the experimental groups of animals, we observe larger average daily gains compared to control animals and a steady trend of increasing average daily gains with age. Which directly affects the productivity of future cows. Feeding a feed additive as early as possible after the calving period helps to increase milk yield and increase the fat content of milk.
Feed additive Immunobacterin-D for short-term use in production experiments on dairy farms has proven its effectiveness in increasing the productivity of animals and as a therapeutic and prophylactic agent in particular:
- dry feed probiotic supplement Immunobacterin-D increases the average daily gain in menstrual calves by 9,4-15%, in 3-month-old calves by 29%, and by 20% in heifers 12 months of age.
- the use of probiotic feed additive Immunobacterin-D increases the hopes of cows by 0,7-2,5 liters per day.
The maximum effect in the use of feed additive Immunobacterin-D to cows was obtained in the period of weaning on the 21st day of use, and in the summer there is also an increase in milk fat content by 0,5%. Due to the improvement of quantitative and qualitative indicators of milk of the experimental group, it is necessary to emphasize the better stress resistance to the influence of environmental factors in cows when feeding feed additives.
