Dependence of milk productivity of red steppe cows on balanced diets

Abstract

Today, livestock farming is characterized by intensive development, rapid adoption of technology and an active increase in animal productivity. The genetic potential of dairy cattle allows for increased milk production, but feed remains a limiting factor. High cow productivity, increased reproductive capacity, and long-term economic feed use can only be achieved with a complete, balanced diet containing all-sufficient nutrients. The research was conducted at a breeding farm for red steppe cattle of the Azovskoye CJSC, Azovskoye District, Omsk Region. The dairy productivity of cows is determined by the quality of their feed and the adequacy of their nutrition. Rumen and postrumen digestion, feed intake, productivity, and cattle health depend on the ruminant’s diet value. The total content of nutrients, macro-and micro-nutrients, vitamins and amino acids in the feed is determined to assess the nutritional value of the feed. Equally important are the physical properties of the meal. When formulating diets for high-yielding cows, the main parameters to consider are particle size, particle length of feed raw material or feed fragments, and the amount of bulk grass feed. At the Azovskoye farm, feeding is done from the Hostin feeder-mixer three times a day. Dairy cows are fed large quantities of bulky fodder, which is a rich source of fibre, which accounts for the structural value of the ration. Milk production increases every year. In 2019, for example, 6,747.3 tonnes of milk were produced, increasing 248.9 tonnes compared to 2018. High productivity, reproductive capacity and the longevity of economic use of breeding cows can only be achieved with nutritionally balanced feed.
