Animal science – once known as animal husbandry – is a sub-discipline of Zoology; the study of all animals. Animal scientists concentrate upon studying the biology of animals that are under the control of human beings. The main focus of animal science has traditionally been upon domestic livestock – such as sheep, goats, horses, pigs, and cattle – but now the discipline has broadened out to include many pet species; including dogs and cats. The Animal Sciences incorporate a holistic understanding of domesticated species – not just understanding their physiology, but also the legal, economic, and ecological significance of rearing animals. Depending upon the course, these broader themes are often available as optional modules. Careers following an Animal Science Masters degree can be very species or specialism-specific. If you choose to focus on cattle, you might yourself suited to a role in the dairy industry for example. An MSc in Animal Science can serve as an route for switching specialisms, and proceeding to veterinary school.
