Extract

The Japanese black cattle (Wagyu) is well known for their high marbling and price meat. Usually purebred calves from Japanese black cattle are used for the station or field progeny testing. If genetic variance of particular traits of the dam breed is much smaller than that of the sire breed, breeding values of sires can be estimated accurately from their crossbred progeny because genetic difference among dams is relatively small and can be ignored. The objective of this study was to investigate the possibility of using crossbred for progeny testing of Japanese black sires. Since marbling scores or carcass prices of Holstein cattle are low and do not vary widely, crossbred between Japanese black and Holstein was chosen in this study.
