Effects 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...
متن کاملInteraction Between Crude Protein Level and Rumen Protected Amino Acids in Starter Diet on Performance of Dairy Calves
BACKGROUND: A limited number of studies have investigated the inclusion of amino acids in calf starter. OBJECTIVES: This study was aimed to evaluate different levels of crude protein in starter and supplement- ing some protected amino acids on efficiency, health status and blood metabolites of dairy calves and to com- pare it with unprotected amino acids. <st...

متن کاملEffects of Rumen-Protected Methionine on Dairy Performance and Amino Acid Metabolism in Lactating Cows
Problem statement: Free Met as one of the most limiting AA in dairy cows would be mostly degraded in the rumen. This study was to determine the effect of different levels of RumenProtected Met (RPMet) on dairy performance and serum amino acid metabolism. Approach: Thirtysix Holstein cows in similar condition were randomly assigned to six experimental treatments with six replicates each. Levels ...
متن کاملDegradation of amino acids by the mixed rumen microbial population.
Degradation of physiological quantities of amino acids by rumen microbes was determined under both in vitro and in vivo conditions. In vitro rate constants for EAA indicated that Arg and Thr were rapidly degraded (.5 to .9 mM/hr); Lys, Phe, Leu and lie formed an intermediate group (.2 to .3 mM/hr); and Val and Met were least rapidly degraded (.1 to .14 mM/hr). In vivo EAA degradation rates were...
