摘　　要：试验旨在研究复方胍基乙酸对肉羊生长性能、抗氧化指标及经济效益的影响。选取240只体重约37.5 kg的肉羊,随机分成3组,每组8个重复,每个重复10只羊。试验期30 d。对照组肉羊饲喂基础日粮,试验1组和试验2组每只肉羊分别饲喂添加5、10 g/d的复方胍基乙酸的基础日粮。结果显示,与对照组相比,试验2组肉羊的末重显著升高(P<0.05);试验1组和试验2组肉羊的平均日增重显著升高,料重比显著降低(P<0.05)。与对照组相比,试验1组和试验2组肉羊血清的超氧化物歧化酶(T-SOD)和谷胱甘肽过氧化物酶(GSH-Px)活性均显著升高(P<0.05);试验2组的过氧化氢酶(CAT)活性、总抗氧化能力(T-AOC)均显著提高(P<0.05),丙二醛(MDA)含量显著降低(P<0.05)。试验1组和试验2组每只羊每天创造的纯利润分别是0.12元和0.69元。研究表明,每只羊添加10 g/d的复方胍基乙酸可以改善肉羊的生长性能,提高抗氧化能力和经济效益。The experiment was to study the effect of compound guanidine acetic acid on growth performance,antioxidant indices and economic benefit of mutton sheep.A total of 240 sheep with body weight about 37.5 kg were randomly divided into three groups,with eight replicates in each group and ten sheep in each replicate.The experiment lasted for30 d.The sheep in control group were fed with basal diet,and the sheep in experimental group 1 and experimental group 2 were fed with basal diet with 5,10 g/d compound guanidine acetic acid,respectively.The results showed that compared with the control group,the final weight of sheep in experimental group 2 was significantly increased(P<0.05),the average daily gain of sheep in experimental group 1 and experimental group 2 was significantly increased,and the feed to gain ratio was significantly decreased(P<0.05).Compared with the control group,the activities of superoxide dismutase(T-SOD)and glutathione peroxidase(GSH-Px)in experimental group 1 and experimental group 2 were significantly increased(P<0.05),the catalase(CAT)activity and total antioxidant capacity(T-AOC)in experimental group 2 were significantly increased,and malondialdehyde(MDA)content in experimental group 2 was significantly decreased(P<0.05).The net profit of experimental group 1 and experimental group 2 were 0.12 yuan and 0.69 yuan per sheep per day,respectively.The experiment indicates that adding 10 g/d of compound guanidine acetic acid per sheep can increase the weight gain of mutton sheep,reduce the ratio of feed to gain and morbidity,and improve economic benefits.
