【摘要】 试验探讨了肌肉苹果酸酶(Malic enzyme,ME)活性与猪肌肉品质的关系,比较了鄂西黑猪、长白猪♂×(野猪♂×鄂西黑猪♀)♀三元杂交猪、长白猪×大约克猪二元杂交猪的肌肉苹果酸酶活性与肉质性状的差异。结果表明,鄂西黑猪的肌肉苹果酸酶活性和肌内脂肪(Intramuscular fat,IMF)含量显著高于长白猪♂×(野猪♂×鄂西黑猪♀)♀三元杂交猪和长白猪×大约克猪二元杂交猪(P<0.05),而长白猪×大约克猪二元杂交猪的肌肉24h的pH值、滴水损失和嫩度显著高于鄂西黑猪(P<0.05)。相关分析表明,肌肉苹果酸酶活性与肌内脂肪含量呈显著的正相关,而与滴水损失和嫩度呈显著的负相关(P<0.05),苹果酸酶活性与肉色呈正相关,但相关性不显著(P>0.05)。更多还原

【Abstract】 The relationship between muscular Malic enzyme(ME) activities and meat quality was analyzed.The difference of muscular ME activities and Intramuscular fat(IMF) in E-Xi black boars,Large-Wild boar-E-Xi black boars hybrid boars and Large-York pigs was compared.The results showed that the ME activities and IMF content of E-Xi black boars were higher than those of Large-Wild boar-E-Xi black boars hybrid boars and Large-York pigs(P<0.05).The meat traits of 24 h pH,dropping loss and shear force of Large-York pigs were higher than those of E-Xi black boars(P<0.05).The ME activities had a significantly positive relation-ship with IMF content and negative relationship with dropping loss and shear force(P<0.05),while its relationship with meat color was insignificantly positive(P>0.05).更多还原
