The use of the enzymativeprobiotic additive "Rumit" in feeding lactating cows in the breeding factories of the Vologda region

Abstract

Relevance and methodology. Milk production is effective for producers only in case of high productivity of the farmed livestock. In the prime cost of raw milk, feed costs account for over 60%, in connection with which the main task of modern science is the development of additives and preparations that can improve the use of feed by animals, which will ensure an increase in livestock productivity. The research team of OOO Biotrof has created an experimental preparation "Rumit" — a complex of live bacteria based on cultured strains of cellulolytic bacteria of deer rumen. The effectiveness of the enzymeprobiotic supplement was studied in the breeding farms of the SKHPK collective farm "Peredovoy" and JSC "Plemzavod Rodina" of the Vologda region on lactating cows with a productivity of over 8000 kg of milk per lactation. To conduct the experiment by the method of balanced groups for a complex of economically useful traits and genetic potential, a control and experimental group of 10–12 animals each were formed. Experienced groups were fed with the drug "Rumit" 50 g per head per day during the day.Results. For 90 days of the experiment, the total density of ciliates in the contents of the rumen of the experimental groups increased by 155.9–173.0 thousand ops / ml, and the significant difference with the control was 13.5.9–171.7 thousand ops / ml. The emergence of new genera of ciliates was noted: in the agricultural production complex the collective farm "Peredovoy" — Epidinium, in the JSC "Plemzavod Rodina" — Isotricha and Ophryoscolex. The increase in the average daily milk yield in the experimental groups was from 6.3 to 9.0% in the context of enterprises, an increase in the fat content in milk by 0.05–0.07% and protein by 0.03–0.07% was noted. As a result, in the SKHPK collective farm "Peredovoy" in the experimental group, 283 kg of milk of basic fat content were additionally obtained, and in JSC Plemzavod Rodina — 112 kg. In terms of per day from one head, it is possible to receive additional profit when feeding "Rumit" in the amount of 24.50 rubles. up to 120.15 rubles.
