The effectiveness of the use of phytoextract based on alfalfa in the feeding of calves

The development of feeding schemes for young animals based on the use of phytobiotic preparations is an urgent task in animal husbandry. The article presents the results of a study on the use of a phytoextract based on alfalfa in feeding calves. The aim of the work was to establish the effectiveness of the use of a phytoextract based on alfalfa in the diets of young black-and-white cattle. The study was carried out in the production conditions of a commodity enterprise of the dairy direction of productivity in the Kemerovo region. For the study, the selection of newborn calves was carried out using the method of pairanalogues. 2 experimental groups (control and experimental) were formed, 20 animals each. Animals of both groups were in the same conditions of keeping and feeding, with the exception of the studied factor. The calves of the experimental group were additionally included in the diet of an extract based on alfalfa by adding to colostrum and milk when drinking (from 1 to 60 days of life, 1.5 mg per head per day). When studying the effectiveness of using an extract based on alfalfa to increase the live weight of calves, the following results were obtained: during 41-60 days of the experiment, the average daily gain in live weight in the experimental group was 675.0 ± 38.1 g, which exceeded by 145.0 g control group (p function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
