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.

Organizational Unit
Veterinary Diagnostic and Production Animal Medicine
The mission of VDPAM is to educate current and future food animal veterinarians, population medicine scientists and stakeholders by increasing our understanding of issues that impact the health, productivity and well-being of food and fiber producing animals; developing innovative solutions for animal health and food safety; and providing the highest quality, most comprehensive clinical practice and diagnostic services. Our department is made up of highly trained specialists who span a wide range of veterinary disciplines and species interests. We have faculty of all ranks with expertise in diagnostics, medicine, surgery, pathology, microbiology, epidemiology, public health, and production medicine. Most have earned certification from specialty boards. Dozens of additional scientists and laboratory technicians support the research and service components of our department.

Abstract

In recent years, consumer interest in pork raised without or with limited in-feed antibiotics and the introduction of the Veterinary Feed Directive have driven producers to look for alternatives to the use of antibiotic growth promoters (AGPs) in feed. There are numerous products already available that have the potential to be considered as AGP alternatives, although the effectiveness of many of these products has so far not been clearly demonstrated. Current data involving these AGP alternative ingredients are widely variable, and studies evaluating their effects lack consistent methodology and reporting of critical information. This leaves a significant gap in or knowledge about the effectiveness of these products and the ability to make comparisons across studies. In order to most efficiently identify useful AGP alternatives, it is necessary to first increase the consistency with which studies evaluating them are conducted. The objectives of this experiment were: 1) to develop and validate guidelines for studies on alternatives to AGPs to ensure progress in developing and assessing the scientific merit of such projects is as rapid as possible and to facilitate the comparison of research results across multiple studies, and 2) to evaluate the effects of example AGP alternatives in varying pen-group sizes.
