Amino acid biosynthesis in mixed rumen cultures.
Mixed rumen micro-organisms, maintained in continuous culture readily incorporated labelled HCO3- and acetate into amino acids. Labelled propionate, in contrast, was utilized only for isoleucine biosynthesis, but failed to label other amino acids to any significant extent. Evidence was obtained showing that in these mixed, i.e. symbiotic, cultures foward tricarboxylic acid-cycle reactions only ...
متن کاملRuminal Protein Degradation and Estimation of Rumen Microbial Protein Production
Animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. Nitrogen has been identified as the foremost source of nonpoint water pollution and the potential negative impacts of N have become an area of public concern. protein degradation from feed ingredients is an important factorinfluencing AA supply to the duodenum. Ruminal proteolysis...

متن کاملGlycoprotein Biosynthesis in Small Intestinal Mucosa
An active multiglycosyltransferase system involved in the transfer of N-acetylgalactosamine, N-acetylglucosamine, and galactose to various glycoprotein acceptors was found in the rat small intestinal mucosa. The present studies are concerned with the subcellular localization of these glycosyltransferases. Satisfactory isolation of smooth and rough surfaced microsomes from the intestinal mucosa ...
متن کاملEstimating forage protein degradation in the rumen
Forage proteins are degraded rapidly by rumen microorganisms and therefore supply relatively small quantities of undegraded intake protein (UIP). Growing cattle with high metabolizable protein requirements and lactating beef and dairy cows respond to UIP supplementation when fed high-forage diets, even though degradable intake protein (DIP) is adequate. This observation suggests that an accurat...
