【摘要】 选择体重90～110 kg的大约克猪16头（公猪6头、母猪10头）进行屠宰，研究性别对试验猪胴体性能及肉品质的影响。试验结果表明，与母猪组相比，大约克公猪组6～7肋背膘厚和皮脂率显著提高52.31%（P<0.05）、29.35%（P<0.01），眼肌面积和瘦肉率显著降低21.35%（P<0.01）、8.53%（P<0.01）;a、b、b₂₄显著提高12.43%（P<0.05）、19.11%（P<0.01）、10.80%（P<0.05）；肌纤维直径和肌糖原含量母猪组分别比公猪组提高14.63%（P<0.05）、62.82%（P<0.05）。背最长肌氨基酸和脂肪酸含量，胱氨酸、棕榈酸和油酸公猪组比母猪组分别提高9.09%（P<0.05）、5.21%（P<0.05）、8.24%（P<0.05），亚油酸母猪组比公猪组提高45.38%（P<0.01）。更多还原

【Abstract】 To study the effect of sex on carcass performance and meat quality, a total of 16 Duroc pigs, including six boars and ten sows with body weight 90-100 kg, were slaughtered. The results showed that backfat thickness at 6-7 ribs and subcutaneous fat percentage of the Duroc boars were significantly increased by 52.31%(P<0.05) and 29.35%(P<0.01), respectively, and loin muscle area and lean meat percentage of the Duroc boars were significantly decreased by 21.35%(P<0.01) and 8.53%(P<0.01) compare with sows, respectively. A value, b value and b value at 24 h were significantly increased by 12.43%(P<0.05), 19.11%(P<0.01), and 10.80%(P<0.05), respectively,when the meat color indicators of the boars were compared with those of the sows. Moreovere, diameter of muscle fiber and content of muscle glycogen were found to be increased by 14.63%(P<0.05) and 62.82%(P<0.05) in the sows. Meanwhile, content of cystine, palmitic acid, oleic acid were significantly increased by 9.09%(P<0.05), 5.21%(P<0.05), and 8.24%(P<0.05), respectively, and the content of linoleic acid were were significantly decreased by 45.38%(P<0.01) in boars compared with sows.更多还原
