Dystocia can result in reduced profits due to offspring loss, increased calf morbidity that may be related to hypoxia or poor passive immunity (Arnott et al., 2012), older dam age at first birth and longer calving intervals (Berry and Evans, 2014). In a recent paper in this issue, Saad et al (2020) compared selection for calving ease versus low calf birthweight and report greater calf performance benefits following selection for calving ease.
