| 中文摘要: |
| 以荣昌猪保种核心群为基础，对荣昌猪不同组合的两系和三系杂交后代进行繁殖、生长、胴体及肉质
性能方面的指标测定。结果表明，在繁殖性能上，大约克× 荣昌（YR）二杂经产母猪总产仔数为13.07（±2.5），与
母猪长白× 荣昌（LR）二杂母猪无显著差异，但显著优于纯种荣昌猪，繁殖性能的杂交优势明显；在生长速度方
面，LR 的日增重为635.28 g，显著高于YR 的日增重593.41 g；杜洛克×长白× 荣昌（DLR）三系杂交商品猪的日增
重和达100 kg 日龄分别为775.88 g、190 d，极显著高于杜洛克× 大约克× 荣昌（DYR）商品猪的相应指标。在胴
体和肉质方面，LR 和YR、DLR 与DYR 在大多数指标上无显著差异。 |
| 英文摘要: |
| Using the core group of Rongchang pig as dam line，we produced two lines and three-line hybrid
offsprings by different combinations，and measured the reproduction，growth，carcass and meat quality index to evaluate
those offspring performances. The results showed that about the reproductive performance，Yorkshire × Rongchang
（YR）two hybrid sows farrowing total number was 13.07（±2.5），there was no significant difference with Landrace ×
Rongchang sow（LR）two miscellaneous sow，but significantly better than purebred Rongchang；in terms of growth rate，
the average daily gain（ADG） of LR was 635.28 g，significantly higher than that of YR with 593.41 g；the ADG and up
to 100 kg days of Duroc × Landrace × Rongchang（DLR）three-line hybrid pig were 775.88 g，190 d，respectively，
significantly higher than those of Duroc × Yorkshire × Rongchang（DYR）commercial pig. There was no significant
difference in most of the indicators about carcass and meat quality between LR and YR and between DLR and DYR. |
