Vorobel M. Milk productivity and metabolic processes in the organism of cows under the correction of vitamin and mineral nutrition

Object of research: Metabolic processes in the organism of dairy cows and milk productivity against background of the premix P 60-5M and the improved VMA. Objective of research: scientific and practical justification for advantages of using the new VMA in structure of mixed fodder K 60-32-89, improved by Phosphorus and Sulfur over the premix P 60-5M in the structure of mixed fodder K 60-32-89 for dairy cows in the summer-pasture period maintenance of livestock in the Precarpathian region. Methods of research: zootechnical, colorimetric, spectrographic, photometric, physiological, microbiological, biochemical, statistical, analytical. Scientific novelty: for the first time on the basis analysis of forages in the grass-concentrate ration of dairy cows in the Precarpathian region developed VMA a new recipe in the structure of mixed fodder K 60-32-89, optimized by Phosphorus and Sulfur. In the research received of new data on the influence of the improvement VMA on the intensity of metabolism processes in organism of cows, its relation to productivity. The degree of implementation: the approved VMA shall be used in the feeding of dairy cows in the summer-pasture period of maintenance to increase milk production and to improve milk composition. Application area: farms of different forms of ownership, higher education institutions under the program specialization of "Feeding Animals and Technology of Forages" and "Technology of Production of Livestock Products".
