BIOCHEMICAL INDICATORS OF BLOOD OF LAMBS OF WESTERN-SIBERIAN MEAT BREED DURING SUCTION WITH EWES, RECEIVED IN THE PERIOD OF LACTATION IOD-POLYMERIC PREPARATION “MONCLAVIT-1”
Obtaining and growing healthy lambs is an important task of sheep breeding and largely depends on the milk content and usefulness of ewe's milk, since milk in the first month of life is the only physiological food product for lambs and, accordingly, a supplier of micronutrients. Therefore, a deficiency in the diet of micronutrients, in particular iodine, can directly affect not only the viability of lambs, but also productivity in subsequent periods of life. The article presents the results of a study of the biochemical parameters of lambs of the West Siberian meat breed during the suction of ewes receiving the iodine-polymer preparation “Monclavit-1”. The object of the study was the lambs (n = 10) of the West Siberian meat breed, which were sucked by ewes of the 1st and 2nd experimental groups, the diet of which included the Monclavit-1 preparation, at a dose of 0.5 and 1 ml per kg live weight, respectively. It was established that the use of the drug by lactating ewes increased the amount of total protein and albumin by 7.4 and 11.7; 9.9 and 13.4; 5.4 and 9.6%, an increase in the concentration of triglycerides - by 12.7 and 23.8% (P <0.05), the content of calcium and phosphorus - by 5.6; 5.8 and 7.1; 8.3%, respectively, in lambs of the 1st and 2nd experimental groups, in comparison with control animals in the first month of life. The most significant was the difference in protein metabolism in lambs of the 2nd experimental group, which indicates an increase in metabolic processes of anabolic nature in the body of lambs.
