为探讨有机硒和无机硒对肉兔生长性能和抗氧化功能的影响，试验选用100只35日龄断奶仔兔，公母各半，随机分为5组，每组5个重复，每个重复4只。Ⅰ组为对照组，饲喂基础日粮；Ⅱ、Ⅲ组在基础日粮中分别添加0.15、0.30 mg/kg的亚硒酸钠，Ⅳ、Ⅴ组分别添加0.15、0.30 mg/kg 的硒代蛋氨酸。预试期7 d，正式期28 d。结果表明：各硒源添加组日增重均显著高于对照组（P＜0.05），其中Ⅳ的日增重最高，料肉比最低，显著低于对照组。Ⅱ、Ⅲ、Ⅴ组间日增重和料肉比差异均不显著（P＞0.05）。Ⅳ组的超氧化物歧化酶（SOD）、谷胱甘肽过氧化物酶（GSH-Px）、过氧化轻酶（CAT）活性均显著高于Ⅰ、Ⅱ组（P＜0.05），丙二醛（MDA）含量显著低于Ⅰ组和Ⅱ组（P＜0.05），但Ⅲ、Ⅳ组间各抗氧化指标差异均不显著（P＞0.05）。由此可见，一定剂量的硒能提高肉兔生长性能和抗氧化功能，且有机硒的添加效果优于无机硒。

Effects of sodium selenite and selenium methionine on the growth performance and antioxidation function of rabbit were studied in this experiment.One hundred 35-day-old New Zealand rabbits were selected and divided into 5 groups with 5 replicats of 4 each,half males and half females.Group Ⅰ (control)was fed with basal diet,and groupⅡand III were fed the basal diet supplemented with 0.15 and 0.30 mg/kg sodium selenite;groupⅣandⅤwere fed the basal diet supplemented with 0.15 mg/kg and 0.30 mg/kg selenium methionine respectively.The whole experiment lasted for 35 days , including 7 d adjustment test,and 28 d formal test.The results showed that:the average daily gain (ADG)of selenium groups was significantly higher than that of control (P < 0.05),and the ADG of low level Se-Met group was the highest and significantly higher than that of sodium selenite groups (P<0.05).There were no significant difference on conversion among groupⅡ,Ⅲ,Ⅳ(P>0.05).Antioxidation index such as SOD,GSH-Px,CAT and MDA in groupⅢ,Ⅳhad signifi-cant effect compared with group ⅠandⅡ (P < 0.05),but no difference was found between group Ⅲ and Ⅳ.The results sshowed that selenium could improved the growth performance and serum antioxidation function of rabbit.The addition ef-fect of organic selenium was better than that of inorganic selenium.
