Biologically active additives as a way to correct clinical blood indices

An urgent task of modern veterinary medicine and zooengineering is not only the development of new preparation and additives for therapeutic and prophylactic purposes, but also the implementation of ways to increase their effectiveness, as well to obtain high-quality environmentally friendly products for the population. In this regard, industrial enterprises increasingly use biologically active additives, including probiotic ones. The ability to colonize the intestinal epithelium and compete with opportunistic microflora allows such drugs to stimulate the immune system, strengthening resistance to disease. Their use poses the task of finding and implementing ways to increase their effectiveness. This article examines the effect of biologically active additives on the biochemical parameters of the blood of calves. The main components of the studied preparations were bacteria that had undergone lyophilization - Bacillus subtilis and licheniformis, as well as adsorbent substances based on a polymineral mixture. To organize the experiment using the analogue method, three groups of black-and-white dairy calves were formed. The experimental groups, in addition to the main diet, received supplements containing milk replacer for 20 days in the amount of 10 g/g/day. According to the presented studies, the supplements had the greatest effect on the content of zinc, β and γ - globulin fractions in the blood of calves of I and II experimental groups - by 4% (p function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
