PECULIARITIES OF STEERS METABOLISM PROCESS WHEN INCLUDING BIOLOGICALLY ACTIVE SUBSTANCES IN DIET AT INCREASED LEVEL
Increased level of vitamins and trace elements in diets for steers helps to optimize metabolism, as indicated by increase in the amount of nitrogen in the rumen fluid by 0.018 p.p., volatile fatty acids - by 10.8 %, digestibility of dry matter in feed - by 3.28 p.p., protein - by 4.07 p.p., better absorption of mineral substances - by 1.0-5.2 p.p., organic selenium - 1.9 times, fat-soluble vitamins - by 4.4-5.2 percentage points.
