Degradation of forage in the rumen of bull at different duration of their incubation in situ and at addition of chelate compound of chromium injecting into the rumen

Ye. O. Dzen

The data about the degradation of organic matter of wheat, rye and barley in the rumen of bull at addition of chelate compound of chromium-methionine injecting into the rumen at different duration of their incubation in situ were presented. It was established the highest level of of organic matter degradation in all probes of forage observed during 4-hours of incubation both at maintenance of animals on a basic ration and at addition of chromium-methionine into the rumen of bull. The increase of duration of incubation of separate corn ingredients in the rumen caused decrease of their degradation. At addition of chromium compound in to the rumen of bull degree of degradation of nutritives of wheat, rye and barley increased. The greatest degradation determined in a wheat both on a basic ration and with chromium-methionine injecting into the rumen while degradation of rye and barley were almost identical.
