Genetic relationships between weight loss in early lactation and daily milk production throughout lactation in Holstein cows

Genetic relationships between weight loss in early lactation and daily milk production throughout lactation in Holstein cows

ABSTRACT: After calving, high-yielding dairy cows mobilize body reserves for energy, sometimes to the detriment of health and fertility. This study aimed to estimate the genetic correlation between body weight loss until nadir and daily milk production (MY24) in first- (L1) and second-lactation (L2)...
