Influence of vegetable biostimulators on physical and chemical parameters of cows’ milk

The results of a comparative study of the effectiveness of plant biostimulators “Biosvit” and “Megasvit” on changes in the physicochemical composition of milk, which was obtained from dairy cows of the Ukrainian black-and-white dairy breed, kept in Ltd “Renaissance +1881” Zolochivskyi district of Kharkiv region are reflected in the article. There were used 2 biological batches in our studies. One batch of the biological product was made on the basis of a dry mixture, which is called ‘11-Tigers by “Eleven Tigers Herbal Bar Energizer” and consists of seven species of plants of foreign origin. The other type is based on a dry mixture of 7 plants of domestic origin. Biologicals “Biosvit” and “Megasvit” experimental groups of animals (D 1) and (D 2) were injected subcutaneously at the rate of 3-4 mg of active substance per 1 kg of the body weight (on average 15 ml) per 1 animal. Biologicals were injected to the above animals five times, every 72 hours. Milk samples, taken from the formed groups of cows, were monitored for physico-chemical parameters. It was carried out that under the influence of two types of drugs “Biosvit” and “Megasvi” the productivity of cows in experimental groups increased, and in the milk samples from the cows in these groups (D 1) and (D 2), there was an increase in mass fraction: fat by 0,19 and 0,2%; protein by 0,15 and 0,16%; lactose by 0,13 and 0,14%; dry matter by 0,35 and 0,45%, skimmed milk powder by 0,15 and 0,19%, protein by 0,16 (P ≥ 0,95) and 0,28% respectively, compared with the control group of cows (K(controlled)). It can be noted that under the influence of the biological product “Megasvit” there was a more significant increase in the mass fraction of fat by 0,11%; protein by 0,25%, compared with similar indicators of the biological product “Biosvit”.
