WAYS TO INCREASE THE BIOLOGICAL VALUE OF COW'S MILK AND USE IT AS A BASIS FOR FUNCTIONAL PRODUCTS
The scientific study was carried out on two groups of cows. The first group received the main ration used in the collective farm + inorganic salts Fe, Cu, Zn, Mn + KI, the second experimental group of cows received the main ration and chelates Fe, Cu, Zn, Mn + KI. The article presents the results of a study of the effect of chelated compounds on the trace element composition of animal blood. In relation to the control group, these data similarly amounted to: Fe - 10.5%, Cu - 36.4%; Zn - 8.5%, Mn - 8.2%. The diffusion of trace elements from blood into milk in comparison with the control group for the II experimental group is 3.2% more for manganese, 10% for copper, 3% for zinc, 21.6% for iron, 7.2% for iodine. In this regard, when feeding chelated forms of mineral additives against control, the level of trace elements in dairy cows of the 2 experimental group was significantly higher: Fe - 34.5%, Zn - 11.8%, Mn - 11.7%, Cu - 50%, I - 7.2%. The high biological value of the milk obtained due to the addition of chelates to the diet of cows, helps to reduce the proportion of trace elements while maintaining the required biological effect, which makes it possible to provide the population with functional food products and makes them indispensable for strengthening the health of the younger generation.
