Diet energy intake and use patterns

Abstract

The purpose of the work is to evaluate the effect of the feed premix "Megamix-Optilak" on the milk productivity of cattle. During research in 2022-2023 in the farms of the Chekmagushevsky district of the Republic of Bashkortostan, the consumption and digestibility of energy of nutrients in diets, energy digestibility coefficients, energy use by dairy cows of the type being created were determined "Bashkir" black-and-white breed, depending on the dose of feeding the feed premix. The object of the research was 80 cows, formed from analogues into 4 groups of 20 heads: control group and I, II, III - experimental. Experimental animals were kept in identical conditions. The difference between the groups was in feeding: animals of groups I – III, in addition to the main diet, received the Megamix-Optilak premix with the diet in doses of 100-200 g/animal per day, the control group was not fed the studied premix. The results of the studies indicate a positive effect feed premix "Megamix-Optilak" on the palatability of ration feed by cows of the experimental groups. Adding the studied premix to the feed mixture at a dosage of 200 g/head. per day contributed to more intensive feed consumption by dairy cows. In addition, the animals absorbed more energy from the main nutrients, including protein - by 10.66%, fat - by 14.14%, fiber - 10.63% (P<0.05).
