The concentration of serum proteins, lipoproteins, leukocytes and lymphocytes in bursectomy and thymectomy Ogol chickens were examined from 5 days to 150 days of age. Concentration of serum proteins and lipoproteins were measured by cellulose acetate electrophoresis. The results summarized as follows : 1. The gamma-globulin concentrations in growing Korean native chickens and Ogol chickens were increased 0.41pm0.01~0.85pm0.05 mg/㎗ and 0.50pm0.01~0.98pm0.08 mg/㎗ from 1 day after to 5 days of age and gradually decreased at 10 days of age, and thereafter increased 0.82pm0.06 mg/㎗, 1.09pm0.04 mg/㎗ at 100 days of age. 2. The serum apha-, beta-, gamma-lipoprotein concentrations of growing Ogol chickens were 74.1pm6.8~240.2pm9.7 mg/㎗, 89.7 5.7~225.8pm11.3 mg/㎗ and 87.6pm4.7-220.3pm10 mg/㎗, respectively. The serum -lipoprotein concentrations from 5 days to 150 days of age Ogol chickens were significantly decreased. 3. The leukocyte and lymphocyte counts in bursectomy and thymectomy Ogol chickens slightly increased from 10 to 100 days of age. However the leukocyte and lymphocyte counts in thymectomy chickens were lower than in untreated chickens. 4. The Ig concentrations of 1 day to 50 days(0.30pm0.03~0.58pm0.04 g/㎗) in bursectomy chickens were similar to those found in untreated chickens and thereafer increased from 50 to 150 days of age(0.58pm0.04~1.21pm0.05 g/㎗). The Ig concentrations in thymectomy chickens increased significantly.
