Abstract: In July and August 1984 the abomasa and duodena of 86 Holstein-Friesian cows, 30 Holstein-Friesian steers and 34 Japanese Black cattle were collected at an abattoir in Hokkaido, Japan, and examined for nematodes. Nematodes were detected in 62 of the cows (72.1%), 3 of the steers (10%) and 19 of the Japanese Black cattle (55.9%). The prevalences of Ostertagia ostertagi and Mecistocirrus digitatus in the cattle were 47.3% and 29.3%, respectively. Other nematodes indentified and their prevalences were : Haemonchus sp. 0.7% ; Trichostrongylus axei 2.7% : Cooperia oncophora 2.7% ; C. punctata 1.3% ; Nematodirus helvetianus 1.3% and Bunostomum phlebotomum 0.7%. The intensity of infection in 93% of the cattle was low ; the number of mature M. digitatus and O. ostertagi estimated was less than 210 and 850 worms per animal, respectively.
