[Effect of bicarbonate level rise on utilization of nonprotein nitrogen 15N by the rumen microorganisms].
The intensity of 15N uptake from labelled urea by a mixed population of the rumen contents microorganisms was studied as affected by various HCO3- levels. Practically there exist a relation between a pronounced positive effect of sodium bicarbonate on the efficiency of urea nitrogen utilization by the rumen fluid microorganisms and the protein synthesis which suggests their combined application to be advisable. However, significance of the differences is not high, first of all due to a great viriation of data for certain animals.
