METABOLISM OF FODDER NITROGEN COMPOUNDS IN RUMEN OF BULLS DEPENDING ON TIME AFTER FEEDING

N.S. Shevelev, N.A. Polozkova

In Black-and-White fistulated bulls concentration of nitrogen compounds was estimated in total rumen content, its different fractions and rumen liquid in 3, 6 and 10 hours after feeding. Comparatively constant proportion of nitrogen compounds was shown to be supported during the experiment due to active homeostatic processes.

Key words: cattle, fistulated animals, ruminants, rumen, rumen content fractions, nitrogen compounds, hoemeostasis.
