One of the most interesting careers today is livestock breeding. Breeders assist with reproduction for such animals as cattle, pigs, sheep and goats. They strive to improve favorable characteristics of these animals (such as higher milk production) by selectively breeding livestock to produce offspring with more desirable traits. Breeders may work on a family-owned ranch, at a large agribusiness facility, or as a self-employed consultant helping farms of all sizes with their breeding programs.
