EVALUATION OF MEAT PRODUCTIVITY AND QUALITY OF MEAT OF CALVES THAT RECEIVED FEED ADDITIVES BASED ON CHELATED COMPLEX COMPOUNDS AND IN-ORGANIC SALTS OF METALS-TRACE ELEMENTS

The influence of the use of feed additives used in the cultivation of calves on the quality of their meat and meat productivity was studied. Calves were given two types of liquid feed additives: 1) freshly prepared solutions of inorganic salts of copper, zinc, cobalt, iron and manganese; 2) solu-tions of chelated complex compounds of these trace elements. A fractional - periodic scheme of their administration was used, which minimizes the effect of physiological antagonism of trace ele-ments. It was shown that the meat of animals treated with complex compounds had a higher content of trace elements and better indicators of fat content and protein.
