Abstract
This study was conducted to examine the enteropathogens and clinical aspects of diarrhea of the 211 Korean native calves during the suckling period. The experimental results were summerized as follows: 1. The 206 Korean native calves (97.6%) were affected with diarrhea during the suckling period. 2. Of 156 diarrheal feces tested, Rotavirus were detected from 108(69.2%) feces of $K^+99$ E coli were detected from 23(14.7%) feces and Eimeria spp were detected from 33(21.2%) feces. But Salmonella spp and Cryptosporidium spp were not detected. 3. Rotavirus were detected from 2 to 84 days of life, $K^+99$ E coli were detected from 5 to 54 days and Eimeria spp were detected from 33 to 84 days of life. 4. Physical appearances of the diarrheal feces were not affected specifically according to the enteropathogens, but were affected by the severity of diarrhea and the diets.
