以不同杂交组合的成年山猪背最长肌（M.longissimus dorsi，LD）为研究对象，研究杂交山猪的肉色性状．三元杂交组合猪肉色评分和a^＊值（红度）高于二元杂交组合，且公猪高于母猪，肉色更鲜红．二元杂交组合大理石纹评分高于三元杂交组合，母猪高于公猪；且肉色b^＊值（黄度）也提示母猪高于公猪，二元高于三元；肉色黄度高表示肌内脂肪沉积相对就多．pH24分别与b^＊值、失水率间呈现显著性负相关（P〈0．05）；而肉色黄度b^＊值高，失水率低．肉色评分与L值（亮度）、a^＊值、b^＊值呈显著性相关，回归方程Y=6．83—0．107X1-0．027X2＋0．261X3（R=0．597，P〈0．05），其中L值、b^＊值贡献率比a^＊值大．研究表明，三元杂交组合可以很好地利用山猪优良肉质性状，保持理想的肉色；1／4山猪血统更有利于肉色红度性状表达；1／2山猪血统更有利于肉色黄度性状表达，且有利于肌内脂肪沉积．

The study was to investigate the meat color change of M. longissimus dorsi （LD） from three kinds of Shanzhu crossbred. The results showed that meat color score and a ^＊ value （Red） in three-way cross swine were higher than those in two-way cross swine. Also boar meat was more reddish than sow＇ s. Comparing marbling score and b^ ＊ value （Yellow） between crossbreds and gender, both index indicated that sow meat was more fat than boar＇ s. Pork in two-way cross swine contained more fat than that in three-way cross＇ s. pH24 was negatively correlated with b ^＊ value and drop loss（ P 〈 0. 05 ）. It was also found that the higher b^ ＊ value was, the lower drop loss was. A regression equation was built between meat color score （Y） and L （ Light, X1 ）, a^＊（X2 ）, b^＊（ X3 ） value, Y = 6. 83 - 0. 107X1 - 0. 027X2 ＋ 0. 261X3 （ R = 0. 597,P 〈 0. 05 ）. From this mathematics model, the contribution rate of L and b^＊ value for meat color was more than a^ ＊ value. Conclusion was that meat color in three-way cross （ 1/4 inherited Shanzhu） was more reddish or ideal, while in two-way cross （ 1/2 inherited Shanzhu） was more yellowish or fatty.
