摘　　要：研究低聚壳聚糖对生长育肥猪抗氧化性能、脂类代谢和肌肉品质的影响。结果表明:与对照组相比,低聚壳聚糖组可显著提高血清总抗氧化能力,其中40mg/kg低聚壳聚糖组达到极显著水平(P<0.01);对血清过氧化氢酶活性、丙二醛浓度和谷胱甘肽过氧化物酶活性无显著影响(P>0.05);可降低血清中总胆固醇、高密度脂蛋白胆固醇和低密度脂蛋白胆固醇的含量,但差异均不显著(P>0.05);20mg/kg低聚壳聚糖能显著提高宰后眼肌L*45min(P<0.05),显著降低眼肌a*45min和a*24h(P<0.05),40mg/kg低聚壳聚糖也能显著降低眼肌a*24h(P<0.05),但两者对眼肌熟肉率、蒸煮损失、失水率、滴水损失和pH值无显著影响(P>0.05)。低聚壳聚糖以40mg/kg添加量较好。This experiment was conducted to study the effect of oligo-chitosan on serum antioxidant capacity, lipid metabo lism and meat quality of growing-finishing pigs. The results showed that serum T AOC was improved,40 mg/kg oligo-ehitosan group reached a significant level（P〈0.01）. There was no significant effect on serum CAT, MDA or GSH-Px（P〉0.05）. Oli go chitosan supplementation tended to decrease the content of TC, HDL C and LDL-C （P〉 0.05）. Supplementation of 20 mg/kg oligo-chitosan increased the loin eye L＂ 4Stain （P〈0. 05） and decreased the loin eye a^＊ 45mis, and （P〉0.05）, and 40 mg/kg oligo-chitosan also decreased the loin eye a^＊ 24 h （P〈0.05）. However, oligo chitosan supplementation did not affect cooked meat ratio, cooking loss, water loss, drip loss or pH （P〉0.05）. The dose of 40 mg/kg was better.
