Effects of dietary protein level and rumen-protected methionine on lactation performance and blood metabolites in postpartum cows.
Lactation responses, such as milk and milk protein yield, to rumen-protected Met (RP-Met) have been inconsistent in studies especially with transition cows and may depend on the MP supply. The objective of this study was to evaluate the interactive effects of RP-Met supplementation with dietary CP levels on lactation p...
