Effect of RumiMix-3 premix on milk productivity and rumen content of cows

Introduction. When feeding highly productive cows with complete feed mixtures, the issue of increasing their milk productivity becomes more complicated. It is possible to partially change the composition of the feed mixture and thereby achieve some increase in daily milk yields. In addition, the productivity of animals increases when feeding feeds pretreated in various ways. However, a more effective method would be to include various feed additives and premixes produced by industry in the composition of the feed mixture. For effective management of the cattle breeding industry in modern conditions, it is necessary to observe all elements of technology and, especially, to make a complete feed mixture according to the periods of the physiological state of cows. The most significant period is the period of milking, in which it is necessary to achieve maximum milk yields from cows. Therefore, various feed additives and premixes should be used during this period. In this regard, the study of the use of the Rumimix-3 premix as part of a feed mixture for dairy cows during the milking period is relevant.

Object of the study. The object of the study was dairy cows of Holstein black-and-white breed.

Materials and methods. Scientific and economic experience was conducted in the conditions of Borisov Farms LLC, Borisovsky district, Belgorod region. For its implementation, 4 groups of cows were selected, 10 heads in each group. The first group, the control group, received the main diet in the form of a feed mixture without the addition of the Rumimix-3 premix, the second, third and fourth groups received the same basic diet, but the specified premix was added to it in doses of 200, 250 and 300 grams per head per day, respectively.

Results and conclusions. Our studies on the testing of the Rumimix-3 premix in doses of 200, 250 and 300 grams per head per day for highly productive cows in the milking phase have shown the high effectiveness of this premix. The dairy productivity of cows increased by 2.6-4.9%, the amount of profit by 3.3-6.8% and the level of profitability by 1.9-5.0% compared to the control, where this premix was not used.
