INFLUENCE OF PREMIX ON BASED METALOHELATOV ON DIGESTIBILITY OF NUTRIENTS HIGHLY PRODUCTIVE COWS
Abstract
Using a mixed-ligand complex of cobalt in the diets of highly productive cows in the second half of the dry period and in the first 100 days of lactation improved the digestion of nutrients of rations of highly productive cows. Based on the data obtained during the scientific and business experience proved that the best effect on nutrient digestibility of forages in the high-performance cows were diets, which included pre-mixes with mixed-ligand complex of cobalt in the amount of 75% of the recommended norm.
The highest rates of digestion of organic matter, crude protein, crude fat, crude fiber have been observed in cows third experimental group at the end of the dry period and in the first 100 days of lactation.
