摘　　要：本试验用发酵花生粕替代育肥猪日粮中的豆粕,通过研究其对育肥猪的生长性能、血清生化指标和抗氧化能力造成的影响,探讨育肥猪日粮中发酵花生粕对豆粕的适宜替代量。试验选用生长育肥期健康生猪60头,品种为“杜×长×大”三元杂交,平均体重为(22±0.89)kg,随机分为3组,每组4个重复,每个重复5头。分别饲喂纯豆粕日粮(对照组),含5%和10%发酵花生粕(试验Ⅰ组和试验Ⅱ组)。预饲期5 d,试验期47 d。结果表明:用发酵花生粕替代日粮中5%、10%豆粕可显著提高育肥猪日增重、降低料重比(P<0.05)。与对照组相比,日粮添加发酵花生粕育肥猪血清中葡萄糖(GLU)、总胆固醇(TC)、总蛋白(TP)、白蛋白(ALB)含量显著升高(P<0.05),尿素氮(BUN)含量显著降低(P<0.05)。发酵花生粕育肥猪血清中超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-PX)、总抗氧化能力(T-AOC)和过氧化氢酶(CAT)等指标显著高于对照组(P<0.05),丙二醛(MDA)含量显著低于对照组(P<0.05)。结论:发酵花生粕可以显著提高育肥猪的日增重,降低料肉比,改善血清生化指标,提高机体抗氧化能力。在本试验条件下,发酵花生粕最大替代量可达10%。This experiment was conducted to investigate the effects of fermented peanut meal in diets on growth performance,serum blochemical index and Antioxidant indexes of fattening pigs.In order to find out the optimal addition ratio of fermented peanut meal in the diets of fattening pigs.60 Du×Ling×Large fattening pigs with an average weight of(22±0.89kg)kg were selected and randomly diveded into 3 groups,with 4 replicates in each group,each repeat with 5 pigs.Only bean meal(control group),5%and 10%fermented peanut mea l(experimental groups I and experimental groupsⅡ).The pre-experiment period was 5 days and the formal experiment period 47.Results:The daily gain was significantly increased(P<0.05),the feed-to-gain ratio was significantly reduced(P<0.05).Compared with the control group,The glucose(GLU),the total cholesterol(TC),the total protein(TP)and the albumin(ALB)in the serum of fattening pigs fed with fermented peanut meal was the significantly increased(P<0.05),the erum urea nitrogen(BUN)was significantly reduced(P<0.05).The activities of antioxidant dismutase(SOD),glutathione peroxidase(GSH-Px),total antioxidant capacity(T-AOC)and catalase(CAT)in the serum of fattening pigs fed with fermented peanut meal was the significantly increased(P<0.05),the content of malondialdehyde(MDA)was significantly reduced(P<0.05).Conclusion:The fermented peanut meal can significantly increase the daily weight gain of fattening pigs,reduce the feed-to-meat ratio,improve serum biochemical indicators and enhance antioxidant capacity,The maximum substitution amount of fermented peanut meal can reach 10%.
