This might be as a farmer, agriculturalist, or hobbyist, and can be practiced on a large or small scale, for food, fun, or profit.
A breeder can breed purebred pets such as cats or dogs, livestock such as cattle or horses, and may show their animals professionally in assorted forms of competitions.
In these specific instances, the breeder strives to meet standards in each animal set out by organizations.
The US Bureau of Labor Statistics reports that large animal breeders that work as veterinarians earned a median annual income of $61,029 in 2006.
For those who are seeking to breed more exotic animals, such as those in a zoo, a bachelor's degree in veterinary science is needed.
