The research purpose is to study an effect of additives (chelaton adsorbent and santochinum antioxidant) in lactating cows’s diets with increased contents of heavy metals and nitrates on physico-chemical and working properties of milk. The basic approach to the research of this problem was in making experimental groups of cows. Efficiency of the co-fed adsorbent and antioxidant to detox from heavy metals and nitrates was estimated with spectrophotometry by measuring their concentration in milk and its derived products. The findings were statistically processed with SNEDECOR software. The article presents experimental data that substantiate efficiency of chelaton adsorbent and santochinum antioxidant co-added in cow’s diets with increased levels of heavy metals and nitrates to improve physico-chemical and working properties of milk. Thanks to their synergetic affect, in animals of Experimental Group III, the piloted preparations provided significantly (P<0.05) increased levels of milk fat (by 0.22%) and protein (by 0.22%). In the same group, these preparations contributed to the significant (p<0.05) decrease in levels of zinc (by 4.75 times), lead (by 2.65 times) and cadmium (by 5.65 times), nitrates (by 2.63 times), and nitrites (by 3.3 times). Levels of 582 Rustem B. Temiraev et al these elements were not beyond maximum allowable concentrations (MAC) in milk. The article’s content is of practical value for agricultural enterprises to detox cow’s milk from heavy metals and nitrates with co-fed chelaton and santochinum preparations.
