Veterinary science began at the Agricultural and Mechanical College, now Auburn University, in 1892 with the arrival of Dr. Charles Allen Cary. By 1907, Cary had built the program into a degree-granting school, and in 1922 the program began moving west of the main campus as Alabama Polytechnic Institute expanded enrollment and programs. In 1957, API bought R. E. Hudson's 373-acre farm on Wire Road, named for the telegraph line along the route. By 1960, veterinary medicine moved its large animal program from the main campus to this location, and in 1970 the small animal program, basic sciences, and administration moved there as well. Large animal medicine was first housed in McAdory Hall, small animal medicine in Hoerlein Hall, and basic sciences, administration, and the Cary Veterinary Library in Greene Hall. A small animal disease program, the Scott-Ritchey Research Center, began within the complex in 1984. In 1987, the college built Overton Auditorium/Rudd Student Center, which was expanded with more classrooms in 2014. McAdory Hall was replaced in 2003 by the J.T. Vaughan Large Animal Teaching Hospital and razed in 2012. Hoerlein Hall was repurposed, with the Bailey Small Animal Teaching Hospital opening in 2013. The seventh oldest veterinary college in the U.S., Auburn's college is the oldest in the South. At one time, it contracted to enroll students from Florida, Mississippi, Louisiana, Tennessee, Kentucky, Georgia, North Carolina, and West Virginia through the Southern Regional Education Board agreement. Many of those states opened veterinary schools with Auburn's assistance. Kentucky has continued its contract since 1951. Auburn's veterinary enrollment is about one-third in each class for residents of Alabama and Kentucky and one-third for at-large states.
