Association between reproductive traits and milk yield, in crossbred heifers

Association between reproductive traits and milk yield, in crossbred heifers

This research was carried out in heifers from a crisscrossing program between the red Holstein and Brahman breeds, in Venezuela. (Co)variance components were estimated and the relationship between milk yield (P305), age (AGE1) and fertility at first service (FERT1) in virgin heifers was investigated...
