摘要: 采用两因子多水平有重复试验设计,对可能影响猪肉品质的品种及氟烷基因型效应进行研究。选取长白猪、约克猪、荣昌猪和约克×长白F1代约长猪4个品种和组合的猪只进行试验,研究表明品种效应对肉质性状的影响较大。各品种和组合按肉质优劣排序为:荣昌猪 >约长猪 >约克猪 >长白猪。约长猪在肉质方面体现出一定程度的杂种优势。氟烷阳性纯合子个体(nn)的肉质性状显著差于阴性纯合子个体(NN)和杂合子个体(Nn);杂合子个体(Nn)的肉质性状居于两纯合子个体(NN和nn)之间,与NN的差异没有达到显著水平,但显著优于nn个体(达5%显著水平)。

关键词: 猪, 肉质性状, 氟烷基因

Abstract: Sixty seven finishing pigs, including Landrace(L), Yorkshire(Y), Rongchang pig(RC), Yorkshire(Y) and Landrace(L) crossbred pigs(YL), were tested in a two factor experiment at multiple levels with repeated observations. The meat quality and carcass traits were studied. The results show that there were significant differences among breeds(P<0.05). In heredity, Rongchang pig has better meat quality than the others breed, and YL has positive heterosis in meat quality. Meat quality was significantly worse(P<0.05) in Halnn pigs than in HalNn and HalNN pigs, but there was no significant difference between HalNn and HalNN pigs.

Key words: PIG, MEAT QUALITY TRAITS, HALOTHANE GENE
