本试验旨在探讨饲粮异黄酮添加水平对肥育猪抗氧化、生长及屠体性能的影响。选取72头健康（阉公猪和母猪各占1/2）的杜×长×大肥育猪（约60 kg）随机分为6组（每组6个重复，每个重复1头阉公猪与1头母猪），对照组饲喂玉米-豆粕型基础饲粮，试验组饲喂在基础饲粮中分别添加20、40、80、160和320 mg/kg异黄酮的试验饲粮。试验期为64 d。结果表明：1）饲粮添加160 mg/kg异黄酮显著提高了血浆中过氧化氢酶（CAT）活性（P＜0．05）；添加剂水平为80 mg/kg时显著提高肝脏中CAT活性（P＜0．05），而添加水平为160 mg/kg时则显著抑制肝脏CAT活性（ P＜0．05）。2）饲粮添加40和80 mg/kg异黄酮显著降低了血浆中氧化型谷胱甘肽浓度（ P＜0．05），添加水平为40、80、160、320 mg/kg时显著提高了血浆中还原型谷胱甘肽浓度（P＜0．05）；添加水平为80和160 mg/kg时显著降低了血浆中丙二醛浓度（P＜0．05）。3）肝脏中谷胱甘肽过氧化物酶（ Gpx）活性随饲粮异黄酮添加水平增加呈显著的线性下降（ P＜0．05），添加水平为80、160和320 mg/kg时显著降低了肝脏中Gpx活性（P＜0．05）。4）肝脏中氧化平衡系数在各添加水平间无显著差异（P＞0．05），但随饲粮异黄酮添加水平的增加表现出显著的线性升高（ P＜0．05）；添加水平为320 mg/kg时血浆中氧化平衡系数表现出高于对照组的趋势（P＝0．08）。5）饲粮异黄酮添加水平对肥育猪的平均日增重、日均采食量、料重比无显著影响（P＞0．05）；对屠体重/率、眼肌面积、平均背膘厚、瘦肉重/率、脂肪重/率等屠体性能指标无显著影响（P＞0．05）；对背最长肌滴水损失、肉色、嫩度、pH无显著影响（P＞0．05）。结果提示，饲粮中添加适宜水平的异黄酮可提高肥育猪抗氧化性能，而添加过高水平的异黄酮则可能降低其抗氧化性能（尤其在肝脏组织），玉米-豆粕型饲粮中添加异黄酮未影响到肥育猪的生长、屠体性能及肉质。
本試驗旨在探討飼糧異黃酮添加水平對肥育豬抗氧化、生長及屠體性能的影響。選取72頭健康（閹公豬和母豬各佔1/2）的杜×長×大肥育豬（約60 kg）隨機分為6組（每組6箇重複，每箇重複1頭閹公豬與1頭母豬），對照組飼餵玉米-豆粕型基礎飼糧，試驗組飼餵在基礎飼糧中分彆添加20、40、80、160和320 mg/kg異黃酮的試驗飼糧。試驗期為64 d。結果錶明：1）飼糧添加160 mg/kg異黃酮顯著提高瞭血漿中過氧化氫酶（CAT）活性（P＜0．05）；添加劑水平為80 mg/kg時顯著提高肝髒中CAT活性（P＜0．05），而添加水平為160 mg/kg時則顯著抑製肝髒CAT活性（ P＜0．05）。2）飼糧添加40和80 mg/kg異黃酮顯著降低瞭血漿中氧化型穀胱甘肽濃度（ P＜0．05），添加水平為40、80、160、320 mg/kg時顯著提高瞭血漿中還原型穀胱甘肽濃度（P＜0．05）；添加水平為80和160 mg/kg時顯著降低瞭血漿中丙二醛濃度（P＜0．05）。3）肝髒中穀胱甘肽過氧化物酶（ Gpx）活性隨飼糧異黃酮添加水平增加呈顯著的線性下降（ P＜0．05），添加水平為80、160和320 mg/kg時顯著降低瞭肝髒中Gpx活性（P＜0．05）。4）肝髒中氧化平衡繫數在各添加水平間無顯著差異（P＞0．05），但隨飼糧異黃酮添加水平的增加錶現齣顯著的線性升高（ P＜0．05）；添加水平為320 mg/kg時血漿中氧化平衡繫數錶現齣高于對照組的趨勢（P＝0．08）。5）飼糧異黃酮添加水平對肥育豬的平均日增重、日均採食量、料重比無顯著影響（P＞0．05）；對屠體重/率、眼肌麵積、平均揹膘厚、瘦肉重/率、脂肪重/率等屠體性能指標無顯著影響（P＞0．05）；對揹最長肌滴水損失、肉色、嫩度、pH無顯著影響（P＞0．05）。結果提示，飼糧中添加適宜水平的異黃酮可提高肥育豬抗氧化性能，而添加過高水平的異黃酮則可能降低其抗氧化性能（尤其在肝髒組織），玉米-豆粕型飼糧中添加異黃酮未影響到肥育豬的生長、屠體性能及肉質。

This experiment was conducted to investigate the effects of dietary supplemental level of isoflavones on antioxidant, growth and carcass performance of finishing pigs.Seventy-two finishing pigs ( half castrated boars and half sows, Duroc ×Landrace ×Large white) weighted about 60 kg were randomly allocated into 6 groups with 6 replicates in each group and 1 castrated boar and 1 sow per replicate.Pigs in control group were fed a corn-soybean meal basal diet, and those in experimental groups were fed the basal diet supplemented with 40, 80, 160 and 320 mg/kg isoflavones, respectively.The experiment lasted for 64 days.The results showed as follows:1) dietary supplementation of isoflavones at 160 mg/kg significantly increased plasma CAT activity ( P<0 .05 ) , and that at 80 mg/kg significantly increased liver CAT activity ( P <0 .05 ) , while that at 160 mg/kg significantly inhibited liver CAT activity (P<0.05).2) Dietary supplementation of isoflavones at 40 and 80 mg/kg significantly decreased plasma GSSG concentration (P <0.05), that at 40, 80, 160 and 320 mg/kg significantly increased plasma GSH concentration ( P<0 .05 ) , and that at 80 and 160 mg/kg sig-nificantly decreased plasma MDA concentration ( P <0 .05 ) .3 ) Liver Gpx activity was decreased linearly with the increase of isoflavones supplemental level ( P<0 .05 ) , and dietary supplementation of isoflavones at 80, 160 and 320 mg/kg significantly decreased liver Gpx activity ( P <0.05).4) Pro/antioxidant balance ( PAB) value in liver did not differ among different supplemental levels, but it showed liner response to the in-crease of isoflavones supplemental level; compared with control group, dietary supplementation of isoflavones at 320 mg/kg tended to increase PAB value in plasma ( P=0 .08 ) .5 ) Average daily gain, daily feed intake and feed to gain ratio were not affected by dietary supplementation of isofalvones ( P>0 .05 );the carcass indi-ces, dressing weight/percentage, logissimus muscle area, average backfat thickness, lean weight/percentage and fat weight/percentage and so on, did not differ among treatments (P>0.05);drip loss, meat color, ten-derness and pH of logissimus muscle were not affected by dietary supplementation of isoflavones ( P>0 .05 ) . It is concluded that dietary supplementation of isoflavones at proper level can enhance antioxidant performance of finishing pigs, while it exerts inhibitory effects on antioxidant performance when at higher level ( especially in liver tissue) , the supplementation of isoflavones in corn-soybean meal diet does not affect growth perform-ance, carcass performance and meat quality of finishing pigs.
