To find a standardized muscle sample for easy measuring fibre diameter in practical pig production, 10 WannanSpotted growing pigs were operated by means of biopsy sampling of biceps femoris,and 50 growing pigs (Anchen,Huai,Large White×Anchen,Landrace×Large White×Anchen,and Large White×Landrace×Huai, 10 of each ) were tested fortheir finishing traits,carcass traits,and meat quality traits including fibre diameter of biceps femoris (FDB) by means of carcass sampling. The results showed that both biopsy and ca...
