Animal Science

The Department of Animal Science originally concerned itself with teaching the selection, breeding, feeding and care of livestock. Today it continues this study of the symbiotic relationship between animals and humans, with practical focuses on agribusiness, science, and animal management.

History
The Department of Animal Husbandry was established in 1898. The name of the department was changed to the Department of Animal Science in 1962. The Department of Poultry Science was merged into the department in 1971.

Abstract

Heat stress (HS) is one of the costliest issues in animal production and certainly one of the primary hurdles to efficient animal agriculture in developing countries. Despite advances in heat abatement systems, the warm summer months are still a financial burden for the US swine industry (> $300 million).1 Heat stress-induced economic losses are a result of reduced growth, poor sow performance, decreased carcass quality, increased veterinary costs, and mortality.1 In addition to elevated ambient temperatures, genetic selection for enhanced protein accretion (i.e. leaner phenotypes) results in increased basal heat production, and this decreases a pig’s thermotolerance. 2 Consequently, identifying nutritional strategies to alleviate the negative impact of HS is of critical importance and likely represents a multibillion dollar global market.
