Effects of a rumen-protected form of methionine and a methionine analogue on the lactation performance of dairy cows
The objective the present study was to determine the influence of a supplemental methionine analogue, the isopropyl ester of 2-hydroxy-4-(methylthio)-butanoic acid, commercially available as MetaSmartTM, on lactation performance, particularly milk protein production. The effects of this preparation were compared with those of a rumen-protected form of methionine, marketed as SmartamineTM M. Exp...

the objective of this study was to evaluate the effects of supplementation of different level protein diets with rumen protected methionine and lysine on performance and ruminal parameters in holstein dairy cows when in their early lactation. twenty one dairy cows in their early lactations were assigned to three treatments in a randomized block design experiment of a 35-d duration period. diets...
متن کاملEffect of feeding rumen-protected methionine on productive and reproductive performance of dairy cows
The objectives of this study were to evaluate the effects of daily top-dressing (individually feeding on the top of the total mixed ration) with rumen-protected methionine (RPM) from 30 ± 3 until 126 ± 3 Days in milk on productive and reproductive performance in lactating dairy cows. A total of 309 lactating dairy Holstein cows (138 primiparous and 171 multiparous) were randomly assigned to tre...
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 کاملRumen-protected choline: A significance effect on dairy cattle nutrition
Choline is a vitamin-like substance it has multi-function in animal production, reproduction, and health. The transition period is most crucial stage in lactation cycle of dairy cows due to its association with negative hormonal and energy balances. Unfortunately, unprotected choline easily degrades in the rumen; therefore, choline added to the diet in a rumen-protected form. The use of rumen-p...
