Why cows die on dairies

摘要

On-farm death of adult dairy cows is a significant problem for both economic and animal welfare reasons. Adult cow mortality losses on dairies have increased in recent years. These losses and their causes are not carefully monitored or evaluated on most dairies, leaving producers and veterinarians without the information needed to manage them. The reasons cows die are multiple and complex, necessitating an improved approach to diagnosis, information management and analysis.
