The aim of the work was to identify the indicators and to study the process of digestion in the rumen of dairy cows when used in typical winter diets with different protein solubility. The peculiarities of digestion in the cattle rumen and nutrient absorption against the using alternative feed which is soilagezernona grass-legume composition (Echinoexloa frymentacea — 40, Vic winter — 25 and Fava beans — 20, pea — 15 % of mass) were deals and analyzed. The advantages of using this type of feed as a substitute for maize silage are shown. In the production of such grass-legume mixtures produced with a well balanced nutritional and mineral substances food, which by its action on the body close to the animal compound feeds and enhances the transformation of feed nutrients into animal products. Implementation of the proposed technology of cultivation and harvesting of succulents allows to organize normalized feeding of dairy cows under modern conditions and to maintain an appropriate level of profitability of milk production while maintaining animal health. Diets with ensilage mixtures optimized composition provided a yield of a certain level.
Partially solved the problem of protein nutrition in cows with a simultaneous decrease of davanat concentrated feed. Found that good effect in feeding dairy cows is achieved by feeding a mixture of pisi with legumes in the form of Serena. The digestibility of crude protein is 63,50–72,15 %, and organic matter 69,76–80,89 %. When corn silage nutrient digestibility is somewhat lower. Experimentally proved that in the rumen of dairy cows in the experimental groups more actively passed the processes of microbial synthesis, as indicated by the high content of total and protein nitrogen and lower ammonia. This is due to the presence of the feed of a larger number of nitrogenous substances of various degrees of solubility.
