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. |
