Supplementing dairy cows with low in protein diets with specific amino acids is a promising strategy to counteract the potential negative effect of metabolizable protein deficiency on productivity. The objective of this study was to quantify the productive performance of lactating dairy cows and their milk quality when they are offered two diets with different crude protein (CP) concentration and when they are supplemented with methionine hydroxy analog (HMTBA). This study was carried out in a commercial dairy farm located in Alfaro Ruiz-Alajuela, Costa Rica, during the first semester of 2014. Twenty multiparous Holstein cows under a grazing system were grouped according to days in lactation and calving number. Two diets with different conc...
