Marykina O. Rationale for use of specialized dairy breeds of different breeding conditions by intensive milk production technology

Object of research: the impact of technological sized groups, feeding full- monomixtures, consumption of dry matter and energy generally mixed diet, maternal behavior in performance, adaptability and bioenergetic parameters animals of different species. Objective: The assessment of the potential inheritance Ukrainian black and white dairy, Ukrainian red and white Holstein dairy breeds and in a large farms with intensive technology of milk and justification of their economic use. Methods: zootechnical - definition of milk production, reproductive ability of cows live weight; technology - forms udder intensity of milk; Laboratory - determination of the quality of milk, feed; ethological - the behavior of cows of various technological groups; statistical - mathematical processing of the results; economic - efficiency in high producing dairy breeds of intensive technologies. Theoretical and practical results, in theoretical terms - expanded range of knowledge of the degree of realization of hereditary potential Ukrainian black and white dairy, Ukrainian red and white Holstein dairy breeds and in a large farms with intensive milk production technology. In practical - it has the advantage of Holstein breed in terms of milk production and adaptation to intensive production technology for comfortable conditions and feeding compared with Ukrainian black and white and red and white dairy breeds. The novelty: for the first time under similar conditions intensive technology comprehensively evaluated and justified the implementation of proven Holstein animals, Ukrainian black and white and red and white dairy breeds genetically caused potential performance under conditions of comfort technology environment, including: Loose-boxed for year-round maintenance-stall system , natural ventilation barn, feeding monomixtures of full-feed table and on the automated milking installation "Carousel." Developed further provisions regarding the usefulness of streaming-guild system of milk production based on the physiological state of high-yielding cows. Degree of implementation: case studies in breeding farms JV "Promin" Arbuzynsk district of Mykolaiv region. Scope - livestock, including dairy cattle.
