Artificial insemination (Al) is used widely in the dairy and beef industries and often performed by farmers themselves. By contrast, sheep breeders generally require assistance from vets when frozen semen is to be used. However, recent experiments with frozen semen are indicating that do-it-yourself Al may soon become a reality.
