Effect of Kaufresh and Active Mix feed additives on the physiological and productive indicators of cows

The use of feed additives in the ration of freshly calved cows is becoming almost an integral feature of modern animal husbandry. Feed additives for freshly calved cows are one of the tools for normalizing the cow’s metabolism and, as a result, a more secure transition to the upcoming lactation. The purpose of the research conducted in 2021-2022 at a typical farm in the Amur region has been to study the effect of Kaufresh and Active Mix feed additives on the metabolic processes and productive indicators of lactating cows. The introduction of Kaufresh feed concentrate into the main cow ration for a short time period in the first days in milk, followed by adding the Active Mix liquid premix in the ration to consolidate the achieved result, has had a positive effect on the physiological and productive indicators of dairy cows. It has also made it possible to reduce the loss of live weight and accelerate the cows’ recovery. Consistent use of feed additives has preserved not only quantitative, but also qualitative indicators of the products obtained. Freshly calved red-mottled cows, aged from the first to the third lactation, have been selected according to the principle of analogue pairs and have been taken for the experiment. One control group and three experimental groups have included 10 cows each. Consistent use of Kaufresh additive in the amount of 200 grams per 100 kg of live weight (from the 1st to the 10th day) and Active Mix additive in the amount of 300 grams per cow daily (from the 11th to the 100th day after calving), has significantly (P function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
