Effect of calving difficulty on reproductive performance
Calving difficulty causes economic loss to operations. The loss can be immediate if the calf is lost and is extended to live calf health issues when births are challenging. Additionally, cows recovering from a tough calving can be predisposed to ovarian dysfunction and subsequent reduced fertility. Anestrous in mature cows naturally occurs after calving, and its length is … [Read more...]
