Swine Health and Production Medicine


Focus

North Carolina is the number two swine state in the U.S. The Swine Health & Production Medicine (SHPM) Faculty are actively engaged with the NC swine industry though research and outreach and are committed to training future veterinarians to serve the industry and private clients

 

Research

The SHPM faculty research programs deliver cutting-edge information to support the U.S. Swine industry. All SPHM faculty are engaged in research programs that are nationally and internationally recognized.

SHPM Faculty at NC State have their primary focus in the following areas of research:

Reproductive physiology and immunology research is aimed at investigating the influence of cytokines and the immune system on corpus luteum function in the pig.

Molecular epidemiology is focused on understanding important multidrug resistant (MDR) food borne pathogens at the pre-harvest and post-harvest food safety levels with the specific goal to determine the dynamics of Salmonella, Campylobacter and Clostridium in swine, retail meat and humans.

Gastrointestinal physiology seeks to understand the pathophysiology of important enteric disease affecting swine with the ultimate goal of identifying improved prevention and therapeutic strategies to mitigate these costly diseases.  Special emphasis is on stress physiology of the pig and its role in swine intestinal health and disease susceptibility.

 

Education and Outreach

Teaching for veterinary students is accomplished at the Teaching Animal Unit (TAU), in Swine Selectives for students in the first three classes of the professional curriculum, senior rotations for students, and in lecture primarily during year 3 of the DVM curriculum.

SHPM Faculty develop strong relationships with practicing swine veterinarians and management within the industry in North Carolina. They collaborate with DVM's and their clients to provide better teaching opportunities for our students and graduate students.

The Faculty are actively engaged in the international swine industry, including a training program for international veterinarians who desire to learn more about large scale swine production in order to improve the health of swine in their countries.
