The effectiveness of the use of feed additive Agolin Ruminant in the rations of lactating cows

Abstract

An important task for livestock farms is the use of plant feed extracts to improve the effectiveness of dairy production. The development of new alternative drugs based on natural plants allows for the biological protection of animals. Agolin Ruminant is multi-functional feed additive is a mixture of high-quality active ingredients of plant origin, which is designed to optimize consumption and improve feed conversion in the dairy industry. The purpose of the work was to find the increase in the productivity of high-yield cows by using feed additives based on plant extracts on a large number of animals. Production tests have been carried out in the dairy complex of LLC “Tambov-milk” in the Tambov region on Holstein cows with actual productivity at the level of 8500–9000 kg of milk per year. Analysis of cow productivity indicates a positive effect of the introduction of the feed additive Agolin Ruminant in the ration of animals. For example, in the control group of cows for 30 days of lactation the average daily milk yield from 1 cow was 27,44 kg, in the experimental group 28,14 kg, which was more than 700 g or 2,55 %. The introduction of the Agolin Ruminant feed additive into the ration of animals in the experimental group had a positive effect on the fat content in milk, which at the end of the research period was 3,69 % in the control group, and 3,71 % in the experimental group or 0,02 abs.% higher. The protein content in milk in the control group of cows was 3,16 %, and in the experimental group 3,18 % the excess was also equal to 0,02 abs.%. Economic calculations indicate the effectiveness and expediency of using the Agolin Ruminant feed additive in feeding highly productive cows. At the sale price of 1 kg of milk for 29,0 rubles the productivity of cows have been increased by 0,7 kg, and the income from 1 head per day has increased by 17,3 rubles minus the cost of feed additive.

The effect of the Ketostop-EL feed supplement on the clinical and metabolic status of lactating cows

“…The diet during this period cannot provide the animal with energy in full, even if it is maximally balanced in terms of nutrients and biologically active substances. As a result, in the first phase of lactation, a negative energy balance is formed, which the cow compensates by mobilizing the body's resources, which leads to a loss of live weight [3,4,9,10].…”

“…Currently, it is not possible to optimize the feeding of farm animals without the widespread use of biologically active substances. Feed supplements containing growth stimulants, hormones and pharmacological preparations, including antibiotics, are widely used in agricultural enterprises [1][2][3][5][6][7][8][9][10][11][12][13][14].…”
