Cross-breeding is widely used in beef breeding. Dairy farmers often have their best cows artificially inseminated with semen from superior dairy bulls. The rest of the cows are then mated to a bull from a beef breed, and the progeny are sold to be fattened. This Hereford bull is being used to cross-breed with Friesian cows. The cow mounting him is coming into heat – cows demonstrate their receptivity by mounting other cattle.
