Abstract:

Authors study effect of the additives to the diet on the physics-chemical and technological milk properties of the lactating cows that receive feed with high level of heavy metals chelaton absorbent and santochinum antioxidant. Grouping cows into experimental groups used to be the basic research approach. 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 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.
