Amino acid concentrations in rumen fluid.
Methods using dialysis or ultrafiltration are described for the collection of extracellular fluid in rumen contents for analysis of amino acids. Marked differences in the concentration of aspartic acid, glutamic acid, and alanine were found in samples of either diffusate or ultrafiltrate and in clarified acidified rumen liquor. Concentrations are given for aspartic acid, glutamic acid, alanine,...
متن کاملAmino 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 کاملMechanisms of Acid Absorption in the Rumen and Impacts on Subacute Rumen Acidosis
A distinguishing feature of ruminants is that they rely on anaerobic fermentation of feeds in the rumen and reticulum (collectively termed the reticulo-rumen) to supply metabolizable energy in the form of short-chain fatty acids (SCFA) and metabolizable protein in the form of microbial protein. While the production of SCFA is a nutritionally desired effect, excessive rates of SCFA production an...

متن کاملEffects of rumen-protected amino acids on ruminant nitrogen balance, plasma amino acid concentrations and performance.
A series of trials was conducted to determine the effects of supplemental rumen-protected methionine (RPMet) and lysine (RPLys) on nutrient metabolism and performance. In situ RPMet N disappearance was less than 4% following 48 h of incubation and was not affected (P greater than .05) by diet or resultant ruminal pH differences, indicating that RPMet was well protected from ruminal microbial de...
