Abstract: Under the practical production conditions, an experiment of weaning at 28 days, 21 days, and 14 days old were done. The results show:On growth traits, the group of weaning at 28 days old grow faster before 70 days old, and the days reach 100kg are fewer; On carcass traits, the carcass of 28 days weaning group is longer, ratio of ham to carcass is higher, but dressing percentage is lower than the other two groups. The difference is significant (P<0.05) on meat quality traits, the group of weaning at 21 days lost more water in meat, and the intramuscular fat of the group of weaning at 28 days is higher. From the economical point of view, weaning at 21 days is better than weaning at 28 days; weaning at 28 days is better than weaning at 14 days. A conclusion can be drawn that early weaning before 21 days old is practicable under the present production conditions if our feeding and husbandry are strict.
