Established in 1980, Carthage Veterinary Service, Ltd. (CVS) provides consulting to independent swine producers and production systems throughout the United States, the Americas, and Asia. In 2013, the practice established a consulting business based in China focused on education, training, farm construction, and systems management. The CVS practice has an active research division, Carthage Innovative Swine Solutions (CISS), which has published findings from health and nutrition trials that are implemented throughout the industry today.  Our investment in quality educational facilities enables us to provide excellent training itineraries with on and off-farm experiences for learners at our Carthage Learning and Development Center (CLDC).
