INFLUENCE OF ADSORBENT AND PHOSPHOLIPID PREPARATION ON BLOOD MORPHOLOGY AND BIOCHEMISTRY OF BULL-CALVES FATTENING IN TECHNOGENIC ZONE
Due to the presence of a synergistic effect in adsorbents with other biologically active additives, including phospholipids, their combined use in the feed of fattening bull-calves significantly reduces the risk of intoxication with heavy metal salts. The aim of the research is to find out the possibility of using adsorbent Toxisorb and phospholipid Lecithin to increase the intermediate metabolism indicators of bull-calves fattening in the technogenic zone by means of diets with excessive heavy metal salts. The research objects were Swiss bull-calves. During the experiment, it was found that for better elimination of HM salts during bull-calves fattening in the technogenic zone, it is advisable to introduce adsorbent Toxisorb in the amount of 1,25 kg/t feed and preparation Lecithin in the amount of 10 g/100 kg of live weight, which helps to activate intermediate metabolism in the body. A more significant physiological effect was obtained when their joint feeding, while the young animals of the 3rd experimental group vs. their counterparts in the control group had optimization of hematopoietic processes due to an increase in the concentration of red blood cells, hemoglobin, sugar, total proteins, calcium, phosphorus, ALT and AST activity. It was also found that joint feeding both feed preparations had the best detoxification effect. This was manifested in the counterparts of the 3rd experimental group compared to the control in a significant (P>0,95) decrease in the level of zinc, cadmium and lead. The concentration of these elements in the blood of bull-calves in the experimental groups was in all cases less than MPC.
