This experiment was carried out to compare the growth rates and reproductive traits between Korean native cattle and Charolais crossbreeds. The results obtained were summarized as follows: The body weight of Charolais crossbreed (CK) was 41, 39, 44, 29% heavier at the age of 3, 6, 12 and 18 months than that of Korean native cattle(K) on the farm performance and was 26, 47, 58, 51% heavier on the station performance test(S.P.T). In the Charolais back-crossbreed (CCK) was S5, 44, 46, 40% heavier on the farm performance and 50, 49, 69, 55% on S.P.T. Body measurement of the crossbreeds was taller, wider and longer than that of K. Age and body weight at puberty of the crossbreeds was earlier and heavier than that of K. The type of parturition of Charolais crossbreeds was 92.6% in normal and 7.4% in abnormal in CK, and 94%, 6,0% in CCK, respectively.
