There are more Holstein dairy twins today than in the past – from just over 3 percent in 1975 per herd to 10 percent or more today.

High milk production seems to figure into more twins, and the vast majority of Holstein twins are fraternal. These twin calves come from separate eggs that are released at the same time from an ovary, but are fertilized by separate sperm.

The result is a challenging situation for many dairy farms. The cow’s nutritional requirements are large. The cow may have difficulty giving birth to twins and passing the afterbirth. It’s possible the dairy will lose both the valuable cow and the twin calves…………
