Efficiency of application in diets of high-productive cows of Actisaf SC 47

Abstract

The paper discusses the technology of growing, keeping and feeding dairy cows in the conditions of Zolotaya Niva LLC, one of the largest high-tech dairy complex in the Smolensk region, a European type for the production of raw cow milk, which has the status of pedigree producer. The structure of the feed and the quality of mixing are determined by means of the Pennsylvania sorting system, the level of feed on the sieves is in line with the normative. The results of the production experiment on feeding dairy cows with Actisaf Sc 47, which has a probiotic effect, indicate better digestibility of the feed when the additive is introduced, the use of the drug contributes to: reducing ketone bodies in milk, the beneficial effect of improved feeding, by including yeast on the health of animals, improving the health of the udder, manifested in a decrease in somatic cells in milk. The milk yield with the use of the additive is increased, the milk protein is also increased, since its absorption in the rumen is improved. With the use of additives, the appetite and eatability of the feed improves, so in the group before feeding the probiotic, the percentage of feed residue on the feed table is higher than in the experiment. Dry matter intake is 4.32% higher when feeding supplements, while feed conversion is increased. Saving feed costs per 1 kg of milk is 0.97 rubles. Saving feed costs per year for a livestock of 1800 animals will amount to 523,800 rubles.
