417. Impact of Early Life Events on the Health and Productivity of Dairy Heifers

In dairy heifers, early life events—including episodes of disease, dystocia at the time of birth, and colostrum feeding—have been associated with subsequent lactation performance. These events may exert their effect directly on lactation performance or indirectly through their effect on the risk of disease, age and body weight at first calving,, and body condition score at first calving. This session will review the long-term effects of pre-weaning events and management practices on health outcomes, reproductive efficiency, and milk production, thus allowing veterinarians and producers to develop efficient calf rearing protocols for optimized performance.
