Among calves’ diseases, digestive diseases most frequently occur in Korea, and especially viral diarrhea is one of the most important diseases. This study was conducted to get some basic information for the control of the viral diarrhea in calves. The samples were obtained from 319 calves with clinical diarrhea from 195 farms in Gyeongnam south area (Gosung, Tongyung, Hadong) from June 2005 to August 2006, Viral detection was examined by polymerase chain reaction (PCR), Etiological viruses were detected from 171(53,6%) of 319 calves, and bovine rotavirus (BRV) were 130 (40,8%) and bovine viral diarrhea virus (BVDV) 41 (12,9%), and no coronavirus was confirmed, Statistical difference was found in BRV detection between summer (32.6%) and winter (57.7%). However there was no seasonal difference in BVDV. In detection rate of the calves under 19days, BRV was highest (55.1%), but BVDV lowest (5.1%). No big difference was in rate among herd size. However, BRV was lowest (26.8%) in the group over 51 heads, but BVDV was highest (19.5%) in the same.
