摘　　要：为了研究日粮中添加精氨酸生素(AAA)对环江香猪肉质及抗氧化功能的影响,试验选用体重28～33kg的环江香猪16头,随机分为2组,每组4个重复,每个重复2头猪。试验组在基础日粮中添加0.08%AAA,对照组为基础日粮。饲喂第30 d,将猪放血处死,收集血液,肝素抗凝,离心分离血浆;分割胴体,测定胴体性状;收集肝脏和背最长肌,-20℃保存,用于实验室分析。结果表明,与对照组相比,日粮中添加AAA可显著提高屠宰率(P<0.05),显著降低脂肪率和均膘厚(P<0.05),对瘦肉率和眼肌面积有提高趋势(P>0.05);可显著提高血浆中Zn的含量(P<0.05),对高密度脂蛋白含量和脂肪酶活性有提高趋势(P>0.05),对总胆固醇含量有降低趋势(P>0.05);可显著降低血浆丙二醛含量(P<0.05),对过氧化氢酶活力有提高趋势(P>0.05)。上述结果提示,日粮中添加AAA可显著提高环江香猪的屠宰率和血浆Zn含量,显著降低脂肪率和均膘厚,增强抗氧化能力,从而改善环江香猪的肉质。This study was conducted to determine the effects of dietary supplementation of arginine activator additiw （AAA） on meat quality and anti-oxidant function in Huanjiang mini-pigs. Sixteen Huanjiang mini-pigs with body weigh： of 28-33 kg were used and randomly assigned into two groups （8 pigs per group, housed in 4 pens with 2 pigs per pen） representing supplementation of 0 or 0.08% AAA in basical diet. At the end of a 30 day feeding period, the pigs wen killed by bloodletting,and the plasma were got by centrifugation in heparin-coated tubes. The carcass were divided and carcass traits were measured. The tissues of liver and longissimus dorsi muscle were collected and saved at -20 ℃ for laboratory analysis. Data showed that,compared with the control group, dietary supplementation of AAA increased （P 〈 0. 05 ） the slaughter yield, as wen as the weight radio of lean meat to carcass and lion-eye area （ P 〉 0.05 ）, while decreased （ P 〈 0.05 ） the weight radio of fat to carcass and average backfat thickness. The plasma content of Zn in piglets fed AAA-supplemented diet increased （P 〈 0.05 ）, as well as the plasma content of HDL and activity of LPS （ P 〉 0.05 ）, while decreased （ P 〉 0.05） the plasma content of CHO, compared with the control group. Dietary supplementing AAA decreased （P 〈 0.05） the plasma content of malondialdehyde, while increased （P 〉 0.05 ） the plasma activity of catalase than that of the control group. These findings suggested that dietary supplementing AAA increased significantly the slaughter yield and plasma content of Zn, as well as the antioxidant ability,while decreased significantly the weight ratio of fat to carcass and average backfat thickness, which result in the improvement of meat quality in Huanjiang mini-pigs.
