Effect of supplementing rumen-protected methionine on production and nitrogen excretion in lactating dairy cows.
Two 4 x 4 Latin square trials (4-wk periods; 16 wk total) were conducted to see whether supplementing rumen-protected Met (RPM; fed as Mepron) would allow feeding less crude protein (CP), thereby reducing urinary N excretion, but without losing production. In trial 1, 24 Holsteins were fed 4 diets as total mixed rations containing [dry matter (DM) basis]: 18.6% CP and 0 g of RPM/d; 17.3% CP and...
متن کاملThe effect of rumen protected methionine (RPMet) on milk composition of lactating Cashmere Rayeni goat
BACKGROUND: Methionine has been suggested as the firstlimitingamino acid for milk production in ruminants. It is importanthow to increase milk protein yield and milk fat in dairy ruminants.OBJECTIVES: This study was set to investigate the effect of rumenprotected methionine (RPMet) on milk composition of lactatingCashmere Rayeni goats. METHODS: 40 healthy singletonCashmere Rayeni goats about 3 ...
متن کاملThe Comparison of the Amount of Methionine Supply by Different Rumen-Protected Methionine Sources
Bioavailability of three rumen protected Methionine (Met) sources with different protection methods (Mepron M85, Evonik Industries, Germany; Methioplus, Soda Nutrition, Italy and Methilock, Tehrandaneh Co. Iran) were evaluated in 2 experiments with 6 canulated non-lactating Holstein cows. In experiment 1, the ruminal in situ and mobile bag techniques were used for assessing ruminal degradabilit...

متن کاملEffects of rumen-protected methionine supplementation and bacterial lipopolysaccharide infusion on nitrogen metabolism and hormonal responses of growing beef steers.
Metabolic demand for sulfur-containing AA increases during inflammation in nonruminants. Therefore, Met supplementation may alleviate the negative effects of infection on N balance. Effects of gram-negative bacterial lipopolysaccharide (LPS) and supplemental dietary Met on N balance, serum hormones and haptoglobin, and plasma urea-N and AA were evaluated in 20 Angus-cross steers (BW = 262 +/- 6...
