Abstract

Differences in nitrogen and RNA contents were found between liquid-associated and solid-adherent bacteria isolated from the reticulo-rumen of ruminants offered various diets. Consequences on the estimation of the bacterial nitrogen flow to the duodenum are discussed.

摘要

从采食不同日粮的反刍动物瘤网胃中分离出的与液体相关和附着于固体的细菌之间，发现了氮含量和RNA含量的差异。文中讨论了这些差异对估计进入十二指肠的细菌氮流量的影响。
