Efficiency of milk cows and physical and chemical properties of milk under the influence of feed additive magnesite
Productive qualities of milk cows studied are: average daily yield of milk, mass fraction of fat, quantity of 1% milk and physical and chemical properties of milk under influence of feed additive magnesite. The magnesite additive in diets of milk cows in a dose of 0,07 g per kg of alive weight increased fat content of milk by 0,13% and increased amount of milk of basic fat content by 4,4%. Inclusion of magnesite in a diet of milk cows of 0,133 g per kg of alive weight allowed to raise their average daily yields of milk by 14,1%, fat content of milk - by 0,15%, amount of milk of basic fat content - by 18,8%. Use of magnesite in diets of milk cows in a dose of 0,203 g per kg of alive weight raised their average daily yields of milk by 16,3%, the content of fat in milk - by 0,21%, amount of milk of basic fat content - by 23%.
