摘　　要：旨在研究复合酸化剂对育肥猪生长性能的影响。选取(154±3)d、体重(90.50±1.12)kg的“杜×长×大”三元育肥猪112头,随机分为2组,每组7个重复,每个重复8头猪,公母各半,对照组饲喂基础日粮,试验组在基础日粮中添加1 500 mg/kg复合酸化剂,试验共70 d,其中预饲期7 d。结果:与对照组相比,试验组平均日采食量(ADFI)无显著差异,料重比(F/G)显著降低(P<0.05),平均日增重(ADG)有升高趋势(P<0.1);试验组粗蛋白质、精氨酸、异亮氨酸、亮氨酸、赖氨酸、苯丙氨酸、苏氨酸和缬氨酸的消化率显著提高(P<0.05);试验组猪血清丙氨酸氨基转移酶(ALT)和乳酸脱氢酶(LDH)活性显著降低(P<0.05),球蛋白(GLO)和总胆固醇(CHOL)含量有升高趋势(P<0.1)。结论:在基础日粮中添加1 500 mg/kg复合酸化剂,有助于提高育肥猪的生长性能,增强养分表观消化率并改善育肥猪的血清生化指标。The aim of this study was to determine the effect of compound acidifier on the growth performance of fattening pigs.A total of 112 “Duroc×Landrace×Large White” ternary fattening pigs,at(154±3) days of age,weighing(90.50±1.12) kg,were used and randomly divided into 2 groups,each with 7 replicates and 8 pigs in each replicate.Half of pigs were males and half females.The control group was fed with the basal diet and the experimental group was fed with the basal diet supplemented with 1 500 mg/kg of the compound acidifier.The results showed that,compared with the control group,the average daily feed intake(ADFI) of the experimental group was not significantly different,their feed-to-weight ratio(F/G) was significantly reduced(P<0.05),and their average daily weight gain(ADG) tended to be increased(P<0.1).The digestibility of crude protein,arginine,isoleucine,leucine,lysine,phenylalanine,threonine and valine in the experimental group was significantly increased(P<0.05);the activities of serum glutathione(ALT) and lactate dehydrogenase(LDH) in the group were significantly decreased(P<0.05),and the contents of globulin(GLO) and total cholesterol(CHOL) tended to be increased in the tested pigs(P<0.1).These results indicated that the addition of 1 500 mg/kg acidifier complex to the basal diet helped to improve the growth performance of fattening pigs,enhance the apparent digestibility of nutrients in the animals,and improve their serum biochemical indexes.
