摘　　要：试验旨在研究不同精氨酸水平对产蛋期五龙鹅肝脏生化、抗氧化指标和肠道抗氧化、免疫指标的影响。选取150只34周龄产蛋期五龙鹅,随机分成6组,每组5个重复,每个重复5只鹅(1公4母)。对照组鹅饲喂精氨酸水平为0.72%的基础饲粮,各试验组日粮精氨酸水平分别为0.82%、0.92%、1.02%、1.12%、1.22%。预试期1周,正式试验期16周。结果显示,1.02%组鹅肝脏甘油三酯(TG)含量显著低于0.72%组、0.82%组、1.12%组、1.22%组(P<0.05)。0.92%组鹅肝脏总抗氧化能力(T-AOC)显著高于0.72%组、0.82%组、1.12%组、1.22%组(P<0.05);1.02%组鹅肝脏谷胱甘肽过氧化物酶(GSH-Px)活性显著高于0.72%组、1.12%组、1.22%组(P<0.05)。1.02%组鹅空肠GSH-Px活性显著高于0.72%组、0.82%组、1.22%组(P<0.05)。1.02%组和1.12%组鹅回肠分泌型免疫球蛋白A(sIgA)含量显著高于0.72%组和0.82%组(P<0.05)。研究表明,饲粮添加Arg可以调节鹅肝脏脂代谢,提高机体抗氧化能力和免疫功能,产蛋期五龙鹅精氨酸推荐水平为1.02%。The experiment was to study the effect of different arginine levels on liver biochemistry,antioxidant indexes and intestinal antioxidant and immune indexes of Wulong geese during laying period.A total of one hundred and fifty 34-week-old Wulong geese were randomly divided into six groups,with five replicates in each group and five geese in each replicate(one male and four female).Geese in control group were fed with a basal diet with arginine level of 0.72%,The dietary arginine levels of each experimental group were 0.82%,0.92%,1.02%,1.12%and 1.22%,respectively.The pre-test lasted for 1 w and the formal test lasted for 16 w.The results showed that liver TG content of geese in 1.02%group was significantly lower than that in 0.72%group,0.82%group,1.12%group and 1.22%group(P<0.05).Liver T-AOC of geese in 0.92%group was significantly higher than that in 0.72%group,0.82%group,1.12%group and 1.22%group(P<0.05).The liver GSH-Px activity of geese in 1.02%group was significantly higher than that in 0.72%group,1.12%group and 1.22%group(P<0.05).The GSH-Px activity of geese jejunum in 1.02%group was significantly higher than that in 0.72%group,0.82%group and 1.22%group(P<0.05).The sIgA content in geese ileum in 1.02%group and 1.12%group was significantly higher than that in 0.72%group and 0.82%group(P<0.05).The study indicates that dietary arginine can regulate liver lipid metabolism and promote antioxidant capacity and immune function,the recommended level of arginine is 1.02%.
