摘  要:
为了研究有机硒对羔羊生长性能和抗氧化能力的影响,试验选用30只体重20kg左右的滩羊羔羊,分成3组,对照组不添加硒,2个补硒组分别添加富硒酵母、亚硒酸钠,其剂量以硒计均为0.1mg/kg日粮,试验期为60d。结果表明:①富硒酵母不能提高羔羊的生长性能。②在30和60d时,2个补硒组血液中谷胱甘肽过氧化物酶(GSH-Px)活性、SOD酶活性,均显著或极显著高于对照组(P<0.05或P<0.01);血清中MDA含量,均极显著低于对照组(P<0.01)。上述结果说明有机硒提高羔羊抗氧化能力的效果优于无机硒。

摘  要:
In the trial,the effects of organic selenium source on lamb′s growth performance and antixidative activities were investigated. 30 lambs with body weight of 20 kg were randomly divided into three groups,the control group wasn't supplemented any selenium,but selenium-enriched yeast and sodium selenite respectively was added up to two test groups at the dosage of 0.1 mg/kg. The results indicated that selenium-enriched yeast couldn′t improve lamb′s growth performance. At 30 and 60 day ages,superoxidedismutase (SOD)activity and GPx activity in the two test group both were higher than that of the control group,the difference was significant (P< 0.05),but malonaldehyde (MDA) level of serum was lower than that of control with marked difference (P <0.01). In conclusion,antixidative activities of organic selenium were better than that of inorganic selenium.
