Hematological indices of cows with similar year-round feeding
The purpose of this study was to examine the effect of year-round housing content and similar feeding of cows on their morphological and biochemical indices of blood. Scientific and economic experiment was conducted on animals of black-motley breed in the dairy complex with loose-box content. The amount of cows - 646, annual milk production per cow 6885 kg. Animals are formed in the technological group on physiological condition and daily yield of milk. For each group with similar productivity, its formulation of the feed mixture, which remains constant and corresponds to the feeding norms, is made. It includes: hay grass-legume, haylage grass-legume, silage corn, a mixture of concentrated feed, salt and premix.
