Effect of mineral-vitamin premix on milk productivity and hematological blood parameters of cows

The application of specialized premixes containing all the necessary elements for effective ration enrichment is main direction normalizing mineral and vitamin nutrition cows. introduction biologically active substances into animal diets in form helps to increase efficiency productivity feed application. purpose our study was investigate effect mineral-vitamin premix Biomix on milk hematological blood parameters experiment carried out Ukrainian Blackand-White Dairy Two groups were formed experiment; each group contains 10 heads. animals experimental fed by at rate 50 g per 1 head day as a part diet. control equivalent amount monocalcium phosphate. diet research made it possible eliminate deficiency phosphorus, copper, zinc, cobalt, iodine, bring level D3 normal. Optimizing cows’ through ensured dairy quality increase. average daily yield cows increased 5.9 % 90 days. fat protein content 0.05 0.07 %, respectively. Cows surpassed ones 153.1 kg gross yield, 1.71 terms 4 percent milk; 7.4 relative (P<0.05). dry matter, calcium, lactose have its total energy value has also increased. Feed consumption decreased 5.1 5.4 digestible protein. Feeding did not negative changes body. Morphological biochemical corresponded physiological norms. An (Р≤0.95), hemoglobin creatinine (Р≤0.95) noted. There tendency erythrocytes, glucose, urea, calcium blood. Key words: cows, Biomix, vitamins, minerals, milk, fat, protein, blood, hemoglobin.
