Seventy-three Colorado cow/calf operations were monitored for calf mortality from birth to weaning as part of their participation in the National Animal Health Monitoring System. Producer-observed causes of calf mortality, and the costs associated with these deaths were obtained. The overall calf mortality during the study was 4.5%, with a total associated cost of $237,478. The mean cost per calf death was $216, of which $208 was attributed to the potential value of the calf and an additional $8 was for veterinary, drug, producer's labor, and carcass disposal expenses. The most commonly reported causes of calf mortality were dystocia (17.5%), stillbirth (12.4%), hypothermia (12.2%), diarrhea (11.5%), and respiratory infections (7.6%). These 5 disease conditions accounted for60% of all calf deaths. A cause was not determined for 19.7% of the calf deaths. Beef producers and veterinarians have the potential to decrease calf mortality and increase profits in cow/calf operations by implementing management strategies and herd health programs designed to decrease the number of calf deaths caused by these disease conditions. |
