Effect of Burdizzor’s bloodless castration on blood picture, serum transaminase activity and growth of Korean calves were observed for 90 days period on indoor feeding. The results obtained were as follows;
1. In complete blood count, hemoglobin, hematocrit, total leucccyte count were shown only little changes comparing with that of controls.
2. In diffenential count, the lymphocytes were significantly decreased in first week following castration, while the neutophils were relatively decreased (with a relative lymphocytosis) in later period of experiment (2 to 12 weeks).
3. Serum transaminase(SGOT and SGPT) and alkaline phosphatase activities were not influenced by Burdizzor’s bloodless castration.
4. On average total gain of body weight, no significant differences were found between castrated and noncastrated groups during the experimental period.
