Use of the RumiMiks-3 premix as part of feed mixture for non-milking cows

This article presents the results of studying the effectiveness of the use of the premix "RumiMix–3" as part of a feed mixture for dry cows. The experiment was conducted in the conditions of LLC "Borisov farms", Borisovsky district, Belgorod region. Studies have established the positive effect of the studied feed additive on the productive indicators and reproductive ability of cows.

Introduction. Effective management of any branch of animal husbandry and in particular cattle breeding is impossible without the use of various balancing feed additives that have a positive impact on the preservation of the health of animals and the realization of their genetic potential for productivity. In this regard, the study of the effectiveness of the use of the premix "Rumimix–3" as part of a feed mixture for non-milking cows is relevant.

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

Materials and methods. Scientific and economic experience was conducted in the conditions of LLC "Borisov farms", Borisovsky district, Belgorod region. 4 groups of cows were selected for the experiment, 7 heads in each group. The first control group received the main ration (RR) in the form of a feed mixture without the addition of the premix "Rumimix-3", the second, third and fourth groups received the same RR, but the specified premix was added to it in doses of 200, 250 and 300 g /head/day respectively.

Results and conclusions. In the course of research, it was found that when feeding the studied premix, the feedability of the bark mixture increased by 1.8-4.1% in the first and second periods of non-milking equally. The use of the additive "Rumimix–3" in the non-milking period contributed to an increase in the average daily milk yields of lactating cows. The maximum yield was obtained in the third group of animals, where a premix dosage of 250 g /head /day was used. It was 4.3% higher than the control variant. The studied premix "Rumimix-3" had a positive effect on the reproductive ability of cows. In the experimental groups, all calves were born alive, in the control one calf was born dead. The live weight of the calf at birth in the experimental groups was greater than in the control by 0.4-0.8 kg. At the same time, it was maximum in the third group of animals. After the first insemination, the percentage of fertilized cows in the experimental groups was 14.2-28.5% higher than the control variant. And with this situation in these groups, there is also a lower consumption of seed doses for fruitful insemination, which significantly reduces the cost of cash for insemination of cows.
