FEED ADDITIVE “LACTUMIN” IN DIETS FOR LACTING COWS
Abstract
The paper presents the results of study of efficiency of the feed additive “Lactumin” used in the diets of lactating cows. According to the data obtained, feed additive “Lactumin” used in compound feeds for highly productive cows in the amount of 0.3, 0.6 and 0.9% or 25, 50 and 75 g per animal per day contributes to extra production of 1.0, 1.2 and 0.9 kg of 3.6% fat milk per cow. The perfect dosage of feed additive “Lactumin” in concentrate portion of diet for highly productive cows is 0.6%, which allows to get additional profit from milk obtained in 96 days in the amount of 79.49 rubles with recoupment of 1 ruble of expense for additive in the amount of 8.7 rubles.
