The relation of veterinarian manpower of the WICHE (Western Interstate Commission for Higher Education) states to the veterinary medicine graduates of the WICHE student exchange programs (SEP) is presented. The states included in the WICHE program are Alaska, Arizona, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, and Wyoming. Tables include details on the location of the WICHE SEP graduates, the number of veterinarians located in WICHE states, and analysis of the relationship of graduates to manpower by state. Among findings were that 51 percent of the SEP graduates in 1975 were located in the home state that had sent them as exchange students, that of the total number of veterinarians graduated from all schools located in the sending states the SEP graduates represent 41 percent, and that the graduates are mobile (e.g., as many pre-1956 graduates of Colorado State University are located in California as are located in Colorado). Other findings showed that out of a total of 3801 SEP-era graduates located in the WICHE region, 642 (17 percent) are SEP graduates. (PHR)
