Concern about the well-being of domesticated animals has increased dramatically in the United States and across many other industrialized countries. The issues involved are complex, and there is widespread disagreement both as to the extent of human responsibilities toward animals and how those responsibilities should be carried out. It is imperative that graduate students are highly trained through education and research endeavors to be able to tackle and work on these issues in their professional career. Therefore the Department of Animal Science at Iowa State University now offers a unique graduate Major in Animal Physiology with a specialization in Ethology along with several new catalogue changes.
