Markelova A. Use of ensilaging khrestotsvitykhi cultures in mixture with a cereal in feeding of sucklings cows

The object of study: nutritional feed efficiency of cows, milk quality, blood biochemistry. Objective: to substantiate the effectiveness of the workpiece mixed ensilage of green mass of grass, grass-legume, corn and cruciferous crops and spend zootechnical and economic evaluation of the use of silos at feeding them to ruminants. Methods: technological, chemical, zootechnical, physiological, statistics. Scientific novelty: for the first time conducted a comprehensive study of the preparation of silage from green mass of grass, grass-legume grasses and corn mixed with winter and ardent rape, colza winter, white mustard, oil radish and studied their productive action when used in feeding cows. Degree of implementation: to increase milk production, reduce nutrient losses and improve the quality of Silo is proposed to establish the optimum ratio of the components in silage maize rape staunch 60: 40%, with oil radish - 75: 25% and grass-legumes with rape ardent - 70 30%. Scope of use: higher education institutions in areas of training, "Technology of production and processing of livestock products".
