| 摘 要： | 本文用54头ES系和30头斯格猪对血清肌酸激酶CK，EC#-（2，7，3，2）]、乳酸脱氢酶LDH，EC#-（1，1，1，2）]和氟烷敏感性与肌肉品质的关系进行了研究。结果表明：常规和药物应激后采血时血清CK活性与宰后45分钟肉质指标存在显著性相关（P＜0.01），血清LDH#-5同工酶和肉质指标高度相关（P＜0.001）。并且血清1ogCK值和LDH#-5同工酶在轻度PSE和正常肌肉猪之间存在极显著差异（P＜0.01）；氟烷阳性猪宰后表现典型PSE肌肉（斯格猪n=3），氟烷阴性宰后虽然未发生典型PSE肌肉，但存在轻度PSE肌肉胴体。

| Abstract: | Eighty-four pigs (54 line ES, 30 Siger) were used in the experiment to study the possible relationships of serum CK (creatine kinase), LDH (lactate dehydrogenase) and halothane sensitivity to postmortem muscle quality. Serum CK activities in nonstressed and drug-stressed pigs and LDH_5 isoenzyme were significantly related to muscle quality parameters at 45 rain. postmortem (P<0.01, P<0.001). There were significant differences in serum IogCK and LDH_5 isoenzyme between pigs for slight PSE and normal muscle postmortem (P<0.01). Halothane positive pigs (n=3) in Siger showed typical PSE muscle, halothane negative pigs in line ES did not produce typical PSE but slight PSE muscle. |
