Influence of silage preserved with a bio-supplement on the young cattle growth and development

To obtain high-quality feed and improve its safety, many domestic and foreign scientists suggest using biopreservatives. Preparations based on lactic acid bacterial cultures (sourdough) have become widespread. In the Omsk Region, distributors of veterinary drugs are actively introducing Microbiovit Yenisei, which has proven itself as a probiotic for young animals of various animal species, consisting of lactic acid bacteria and yeast cells. The aim of research is to study the effect of silage (sugar sorghum "Galiya" mixed with fodder beans "Sibirskie"), canned by "Mikrobiovit Yenisei", on the growth and development of young cattle. The experimental part of the work was carried out at the Omsk National Research Farm for three months on 6-month-old black-and-white bulls (n=18). The control group consumed the main economic ration, I experimental - the main ration + silage from sugar sorghum "Galia" mixed with fodder beans "Sibirskie", preserved with the bioadditive "Mikrobiovit Yenisei" at a dilution of 1:100, II experimental - the main ration + silage from sorghum sugar "Galia" mixed with fodder beans "Siberian". In bulls of I and II experimental groups, growth activity increased due to nutritional value silage (BEV, crude protein, crude fat, etc.). The introduction of the preservative bioadditive "Mikrobiovit Yenisei" into the silage of the I experimental group made it possible to increase the digestibility of the feed by 1.9-6.4 % according to the coefficient of digestibility. The average daily gain in live weight in animals of the I experimental group was 6.6-14.2 % higher than in the II experimental and control groups, respectively. Thus, all of the above indicates the positive effect of "Microbiovit Yenisei" on the quality and nutritional value of silage, which contributes to better absorption of nutrients in the stomach of ruminants.
