Abstract

Abstract The influence of such vegetable crops, as table beet and fodder carrots, and natural coniferous extract in the diets of cows in 8-9 months of pregnancy is investigated. The use of food composition caused a decrease in the concentration of heavy and toxic metals in the milk of highly productive black-and-white cows with annual productivity of 6000 kg in the conditions of anthropogenic pollution. The type of feeding-silage-hay application was investigated. Against the background of the main diet animals of experimental groups are additionally fed is 30, 50 and 80 g per head per day of beets and a similar amount of carrots as fodder. Natural coniferous extract (liquid) in a dose of 5.0 ml/head was fed in a mixture with feed. Table beet, carrot and natural coniferous extract ( liquid) with high antioxidant and sorption simultaneously properties in a mixture with feed rations. In this way, it is carried out to supplement the body of cows with a complex mixture of vitamin C, vitamin B, vitamin E, selenium, spicy-aromatic plants. This method allows more successfully solving the problems associated with metabolism, with the accumulation of heavy metals in the milk of animals with a year-round table method of maintenance. The studied phytogenic feed additives caused an increase in the digestibility of nutrients in diets, a significant decrease in the accumulation of Zn, Cu, Pb, Cd, As, Hg, Fe+2 in the body.
