Research Focus

Animal Welfare/Well being and protection:

Stress in agricultural species. OBJECTIVE: Assess the well-being of agricultural animals in various environments, commercial systems, or the application of management practices.

APPROACH: Develop research plans that focus on the well-being of agricultural animals in commercial systems in California and assess alternative systems.

Informational transfer of scientific data on welfare of agricultural species. OBJECTIVE: To develop effective and efficient venues to transfer information on the well-being of agricultural animals to the appropriate audiences including producers, animal protection groups, regulation and policy makers, consumers, and scientists. APPROACH: Using both traditional and innovative communication methods, extend and expand knowledge to end-users that will assist in making economic, political and justifiable welfare decisions and strategies on the use and methodology of agricultural animals as food and companions in California, the US, and globally.
