In the Newberry laboratory, our research concerns the behavior and well-being of animals, with a focus on environmental enrichment, social behavior, and human-animal interactions. We use behavioral measures such as vocalizations, exploration, and play to assess affective states. We also investigate animal preferences, motivations, and decision-making to gain insights into the inner subjective lives of animals. Our goal is to develop methods for improving animal care through environmental enrichment, social grouping strategies, handling and training methods, and housing design. We also seek methods to prevent and control abnormal behavior. We work with a variety of species in agricultural, laboratory, and zoo settings, as well as with companion animals.

A current focus is identifying factors contributing to the development and expression of injurious behavior in animals. We are characterizing the behavioral, morphological and neurobiological characteristics of aggressive and cannibalistic individuals with the aim of understanding the mechanisms underlying these behaviors. The role of individual and social learning in the spread of injurious behaviors is also under investigation. This information is used to develop humane animal management systems that reduce the risk of animal injury and promote animal well-being.

Biographical Information

Ruth C. Newberry, Associate Professor, received her B.Sc. in biology and her Ph.D. in agriculture from the University of Edinburgh in 1979 and 1983, respectively. She held a fellowship from the Natural Sciences and Engineering Research Council of Canada at the Pacific Agri-Food Research Centre in Agassiz, British Columbia from 1983-1985. She was subsequently employed there as a research scientist until 1996, when she joined the faculty of the Departments of IPN and Animal Sciences. She
was the first faculty member appointed in the Center for the Study of Animal Well-being (www.vetmed.wsu.edu/depts-CSAW). She is a Past President of the International Society for Applied Ethology (www.applied-ethology.org), and is currently a scientific advisor to various groups addressing issues of farm animal well-being.
