Why we cross-breed our cattle
It was once believed that purebred cattle were the best way to produce great beef. But in the last number of years, scientists and cattle ranchers have recognized the benefits of cross-breeding, or what is called heterosis. Heterosis means hybrid vigor. It is a way to increase the positive traits of a breed. Like mutts among dogs, cross-bred cattle tend to be stronger and healthier and exhibit few of the negative traits that purebred animals can.
