The research of our laboratory is focused on
nitrogen metabolism in the rumen, ammonia utilization, contribution of
soluble and non-protein nitrogen to the non-microbial N flow to the intestine,
manipulation of rumen fermentation and methods of improving the efficiency
of microbial protein synthesis in the rumen. An important part of our
program is studying feed N metabolism in the ruminant by intrinsic labeling
of plant N fractions using stable isotopes (15N). This technique allows
obtaining 15N-labeled plant N fractions having different rate and extent
of digestion and quantitative measurement of the metabolic transactions
occurring in the rumen and post-ruminally..
