EFFICIENCY OF DIET WITH THE RATIO OF HAYLAGE TO GREEN MASS OF PERENNIAL GRASSES 1:1 FOR DIARY COWS
Abstract
Performance traits of animals largely depend on the feeding quality. The paper presents the results of experimental researches on development of diet structures with different ratios of concentrates, corn silage, predominance of haylage of perennial grasses and green mass in ratio of 1:1 in the summer pasture period. As well as impact of the developed diet on diary performance, content of fat, protein, lactose in milk, morphological and biochemical parameters of blood and economic indicators. Qualitative and quantitative composition of rumen microflora has been determined and a comparative analysis of the balance of microorganism has been presented.
