巴克夏和里岔黑猪不同杂交组合生产性能的比较研究
Comparative Studies on Productive Performances among Different Cross Combinations of Berkshire and Licha Black Pig
摘要
Abstract
In order to test the cross performance of Berkshire and Licha black pigs and pick out the valuable cross combination,seven cross combinations were designed in this study,namely Berkshire × Luchuan (BLu,2 224 heads),Berkshire × Licha black pig (BL,18 555 heads),Berkshire × Yushan black pig (BY,660 heads),Berkshire × Weizhu (BW,366 heads),Licha black pig × Luchuan pig (LL,2 689 heads),Licha black pig × Yushan black pig (LY,706 heads) and Duroc × Licha black pig (DL,1 026 heads),and 16 traits containing growth,fattening,body size and reproductive performance were used to compare pros and cons of the 7 cross combinations.The performance test results showed that DL's overall performance was the best.All of its recorded traits were excellent except litter size and hip width,which were at the ordinary level.BL's overall performance was in the second place:except litter size,feed conversion ratio in fattening period and backfat thickness at 100 kg were not as good as DL.Most recorded traits of the remaining 5 cross combinations were ordinary or bad,so they were not suitable to be commercialized.In order to further understand the productive performances of DL and BL,DL and BL were slaughtered to test their meat production performances.Except marbling score and intramuscular fat content,all carcass and meat quality traits of BL were better than their counterparts of DL.In particular,the thoracic vertebrae number of BL was 1.33 more than that of DL (P=0.003).For the hog,besides of the production performance,body appearances were also very important,especially the coat color.All BL pigs were black,while coat color segregation existed in DL.Most of DL pigs were black,but some of them were covered with some other coat colors.In general,our combining ability test results indicate that the overall performances of BL and DL are better than that of the rest 5 cross combinations,the market prospect of BL is better than that of DL.关键词
