Abstract
Values are tabulated for body weights at birth and at 3 and 6 mth of age of 11 Korean, 10 Aberdeen-Angus (AA), 27 Holstein-Friesian X (AA X Korean) and 14 Charolais X Korean calves. Least-squares estimates of the effects of genotype, year of birth, season of birth, age of dam ( less than or equal to 3, 4 or more than or equal to 5 yr) and sex of calf are given. At the 3 ages resp., Charolais X Korean animals weighed 31.48, 93.02 and 172.81 kg (10.35, 36.72 and 42.02 kg heavier than the corresponding weights of Korean native cattle) and Holstein-Friesian X (AA X Korean) animals 32.79, 96.12 and 204.38 kg (11.66, 39.82 and 73.59 kg heavier than the corresponding Korean cattle).
