为探究妊娠湖羊补充左旋精氨酸（L-Arg）和硒（Se）对初乳及羔羊初生重的影响，本试验选取体重相近、同期发情处理的已孕湖羊20只，随机分为4组（每组5只，饲喂相同的基础日粮），分别为Se 组（饲喂 Se 含量为0.3 mg/kg的日粮）、Arg组（每天静脉注射70 mg/kg体重的L-Arg）、AS组（饲喂Se含量为0.3 mg/kg的日粮结合静脉注射70 mg/kg体重的L-Arg）、对照组。结果表明：与对照组比较，Arg组和AS组的羔羊初生重和初乳中乳蛋白含量分别提高了16.2%、11.3%和15.8%、13.3%（P＞0.05），Se组和AS组初乳中的超氧化物歧化酶（SOD）、谷胱甘肽过氧化物酶（GSH-Px）活性显著提高（P ＜0.05），Arg组初乳中的GSH-Px 活性显著提高（P ＜0.05），Se 组、Arg 组和AS组的IgG水平分别较对照组提高了12.7%、16.6%和22.6%（P＞0.05）。由此可见，妊娠湖羊补充L-Arg和Se提高了初乳的抗氧化性、初乳中乳蛋白和IgG的含量及羔羊的初生重。

To study the effects of L-Arg and selenium supplementation to pregnant Hu Sheep on components,anti-oxidative capacity,IgG of colostrum and birth weight of lambs,20 pregnant Hu Sheep ewes with similar weight and estrus synchronization were selected and allotted randomly into 4 groups (five in each group,fed the same basal diets):Se group (diets adding 0.3 mg/kg of Se were fed),Arg group (intravenous injection of 70 mg/kg body weight of L-Arg per day), AS group(diets which adding 0.3 mg/kg of Se were fed and intravenous injection of L-Arg 70 mg/kg body weight simulta-neously per day),control group.The results showed that:compared with control group,the birth weight of lambs and milk protein content in Arg group and AS group increased by 16.2%,11.3%and 15.8%,13.3%respectively(P>0.05),the ac-tivity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) of colostrum in Se group and AS group in-creased significantly(P < 0.05).The activity of GSH-Px of colostrum in Arg group increased significantly(P < 0.05).The levels of IgG of colostrum in Se group,Arg group and AS group increased by 12.7%,16.6% and 22.6% respectively (P >0.05).In conclusion,supplementation of L-Arg and selenium to pregnant Hu Sheep increased the anti-oxidative ca-pacity of colostrum,the content of milk protein and IgG,and the birth weight of lambs.
