Twin births in beef cattle: Double your pleasure?
Dr. Carl Dahlen
Minnesota Farm Guide
Twin births occur in <1 to 7 percent of cattle depending on breed and genetics. Though fairly rare, it helps to prepare for the possibility of twin births prior to calving season. Gestation length of twins is from 1 to 2 weeks shorter than for single calves, so if a cow became pregnant with twins early in the breeding season she will likely be one of the first to calve. Sometimes this happens unexpectedly ahead of your target calving dates.
