The relationship between the incidence of calf white scour and alcohol stability of cow's milk (Utrecht abnormality) was investigted in 16 pairs of Japanese black cows and their calves with white scour winthin six weeks after birth as well as 5 pairs of healthy controls. Of 16 cows with diseased calves, 9 (56.3%)(Group A) were positive for alcohol test, while 7 (Group B) were negative. The mean concentrations of blood NEFA and beta-lipoprotein were higher and the milk fat rate was lower in cows with diseased calves than controls, and their calves showed hypoliposis. Also, the mean concentration of blood ammonium was higher and glucose and calcium in whey were lower in group A than B. And the mean TG values were higher in group A than B. Menbutone (5 g/day) was orally administered for 2 days to 9 cows of group A. Resulting in their milk turned to negative in 3 days and calves recovered from scour. Whey glucose were increased after administration of menbutone. The results suggested that the white scour in calves and the Utrecht Abnormality of milk might be due to the negative energy balance in cows, which was improved by menbutone treating
