Hematological surveys using Bendixen's and Goetze's Key for bovine lymphosarcoma were made in dairy herds which have been composed of the cows imported from United States, Canada and Japan, and their calves in the area of Taegu and Chung-Nam. The results obtained were summarized as follows: 1. Of 521 cattle, 15(2.9%) were hematologically positive for lymphosarcoma; 28(5.4%) were suspect with Bendixen's Key, and 7 (1.3%) were positive; 26(5.%) were suspect with Goetze's Key. 2. Of 14 herds, 5 were involved in positive or suspect for lymphosarcoma with Bendixen's and Goetze's Key more than 5 per cent. Of the above 5 herds, 3 were involved in positive or suspect more than 30 per cent. These findings suggest that repeated hematological examinations and continuous clinical observations are required in the herds showed higher level of per cent of positive or suspect.
