Polulikh M. Metabolic and productive effect of improved protein-vitamin-mineral additives in feeding of dairy cows

The object of the research: cows, forage, rations, physiological and biochemical parameters of rumen and blood, milk productivity. The aim of the study: to justify the using in the feeding of high yielding dairy cows in the Precarpathians of new PVMS made on the basis of extrudate fava beans, and rapeseed (replacement of sunflower, soybean meal and feed yeast, components of PVS 60-1-89) and scarce in the area BAS (macro- and micronutrients, fat-soluble vitamins). Research methods: zootechnical, colorimetric, spectrographic, microbiological, physiological-biochemical, and statistical. Scientific novelty: for the first time on the basis of high-protein forage crops typical for Precarpathians (beans forage, seeds of winter rape), and limiting zonal BAS developed a new PVMS for dairy cows in winter maintenance. For the first time, against this background, studied a number of physiological-microbiological parameters in the rumen and blood and established their connection with the transformation of nutrients of feeds in production. Degree of implementation: to maximize the genetic potential of dairy cows are encouraged to use in their feeding in Precarpathians new PVMS, the competitiveness of which is confirmed by the patent of Ukraine. Application area: farms of various organizational-legal forms, institutions of higher education in the field of "Forage production", "Animal nutrition and feed technology"
