This experiment was carried out to test performance of the domentic purebred fowl. The purpose of this experiment was to compare the productive performance of the purebred fowl to obtained basic materials for laying performance improvement by means of cross breeding. In this study, 1, 200 chickens was used-that is 6 purebred strains White Leghorns(720 chickens), 1 purebred strain Rhode Island Reds (120 chickens), 1 purebred strain New Hampshires (120 chickens). The results obtained in this study are as follows; 1. The average Viability of brooding, rearing and laying period was best for Rhode Island Reds and E. Strain among White Leghorns. 2. The average body weight at 8 weeks, first egg production days, 500days of age in W. L. was 546.86g. 1431.37g, 1738.34g, respectively, but there was no significant difference among. purebred strains of W. L. 3. The average Sexual maturity of 50% egg production was 170.58 days in W. L., but R. I. R. and S. N. H. were 189.94 days, 182.42days, respectively. There was significant difference at 1 % level among Strains. 4. The average hen-housed egg production was 214.16 eggs in W. L., but R. I. R. and S. N. H. were 214.22 eggs, 196.74 eggs, respectively. There was significant difference at 1% level among Strains, but the highest hen-housed egg production (231.84 eggs) was E. Strain among strains. 5. The average egg weight was 54. 48g in W. L, but R. I. R. and .S. N. H. were 56.12g, 54.90g, respectively, The highest egg weight (57.69g) was Coronial Strain of W. L. among strains. There was significant difference at 1 % Level among strains. 6. The average feed requirement was 3.01 in W. L. but R. I. R. and S. N. H. were 3.23, 3.52, respectively the highest feed requirement (2.79) was Coronial Strain of W. L. among strains. There was significant difference at 1 % level among strains. 7. On the basis of the results of this study, the productive performance was best for C. D. E. strains among W. L. and R. I. R.
