摘要：

A population-based historical cohort study design was used to investigate the effects of a cesarean section on calf mortality, fertility, milk production and culling on 35 Dutch dairy farms. The data were collected during a routine herd health and production control program. Cows undergoing a cesarean section had a higher calf mortality rate, a longer interval from first service to conception and a smaller risk for retained placenta than control cows, those with spontaneous deliveries and those with dystocias. Cumulative milk production at 100 days was lower and the risk of being culled was higher for cows with cesarean sections than for the control cows.
