INFLUENCE OF TIME AFTER FEEDING ON ENZYMA TIC-ACTIVITY IN DIFFERENT MICROBIAL-POPULATIONS FROM RUMEN DIGESTA

The activities of polysaccharidases and glycosidases were monitored in the liquid-associated bacterial (LAB) protozoa (LAP) and solid-associ ated bacterial fractions (SAB) separated from bovine rumen content col lected 1 h before and 3 h after feeding. Enzyme activities were most a ctive in the SAB and remained constant in the LAP. Enzymes involved in the degradation of soluble carbohydrates increased in the LAB 3 h pos t-feed period and at the end of the post-prandial period (1 h before) in the SAB.
