[ Method ] Pigs were given diets with the addition of tetracycline. After 45 d of tetracycline induction, experimental pigs were weighed and slaughtered for parameter determina- tion. [ Result] The lean meat percentage of experimental pigs was improved by 8.92%, but various blood biochemical parameters and carcass components exhibited no significant changes. [ Conclusion ] Under tetracycline induction, transganic pigs harboring IGF-I gane demonstrated an increase in lean meat percentage without abnormal changes in other parameters.展开更多
