Full sib sires produced by the transplantation of fertilized ovum and their progenies were investigated in order to clarify the differences within their performance test records and meat production performance of their progenies. The clear differences were found in DG, feed conversion, the rate of roughage intake, and increasing amounts of body measurements (body weight, withers height, chest depth and thurl width) on the performance testing. The sire effect was significant for carcass weight (P<0.05), M. longissimus thoracis area (P<0.01), rib thickness (P<0.01) and subcutaneous fat thickness (P<0.05) of their progenies. The significant effects of sex of progeny were not found on meat of carcass traits without carcass weight. The genetic variations in full sib sires were comparatively large and they may have high influences in meat production performance of their progenies.
