About the Animal Industry Report

The annual ISU Animal Industry Report summarizes the university's research activities that relate to the animal agriculture industry. The reports combine research papers from faculty from various departments, including Agricultural and Biosystems Engineering, Animal Science, Natural Resource Ecology and Management, Economics, Veterinary Diagnostics, and Production Animal Medicine. Report topics vary by year and include animal products, beef, companion animals, dairy, environment, equine, poultry, sheep and swine industries in Iowa and the teaching areas in ISU's animal science department.
