• For 6 years, 5 Japanese Black cows of the same herd showed anorexia, depression, and dehydration with no feces in the rectum. Biomedical examination of 3 animals showed severe hypokalemia and hypochloremia. Although the first 3 animals died or were slaughtered (causes unknown), necropsy results showed that the cow in case 4 had intestinal obstruction due to phytobezoar derived from napier grass, fed mainly to the cattle as roughage. Therefore, farmers were recommended to avoid the hard root-stem portion of napier grass as roughage. Consequently, less phytobezoar was recovered from the fifth cow, and no similar clinical case of intestinal obstruction was observed thereafter. This is the first report on intestinal obstruction caused by phytobezoars derived from napier grass.
