贵州剑河白、黑香猪生长发育测定

Determination of growth and development of White and Black Xiang pig in Guizhou Jianhe

对剑河白香猪、黑香猪零世代、一世代、白香猪与大约克夏猪杂交F1代2～6月龄的生长发育数据进行了测定,在同条件下与从江香猪的生长发育及饲料报酬进行比较。结果表明,白香猪与黑香猪零世代、一世代在体重、体高、体长、胸围等指标上差异不显著(P>0 05),与从江香猪差异也不显著(P>0 05)。剑河白香猪与大约克夏猪正、反交试验显示,除体重外,体长、体高、胸围指标F1代间无显著差异(P>0 05),且正、反交F1比纯繁的剑河白香猪的体重、体尺指标均高,差异极显著(P<0 01)。

The periodical tests have been made to collect data about growth and development of 2-6month pigs,including the zero and the first generations of White and Black Xiang pig,both originated from Jianhe county,Guizhou province and the F1s with Yorkshire as the paternity and White Xiang as maternity.Repeated tests under the same conditions have also been conducted on the growth and the feed conversion rates of White,Black and Congjiang Xiang pig.The results of the tests indicate that the differences between the zero and the first generations of White and Black Xiang pig in weight,length,height and chest size are not distinctive(P>0.05).No difference is also observed in comparison with Congjiang Xiang pigs(P>0.05).The tests on positive and negative F1s of White Xiang pig and Yorkshire indicate of that all indexes of length,height,and chest size except weight show no distinctiveness.As compared with pure breed of White Xiang pig,the weight and length of the F1 are distinctive,that is,larger than those of the pure breed of White Xiang pig(P<0.01).
