| 摘 要： | 选取288只42周龄健康农大3号商品蛋鸡,随机分为6个组,设4个重复,在基础日粮中以亚硒酸钠的形式添加硒0.3mg/kg为对照组;其余各组以纳米硒的形式分别添加硒0.3、0.5、2.5、5.0mg/kg和10.0mg/kg。试验期为60d。结果表明:日粮中添加2.5～10.0mg/kg纳米硒能显著提高全血硒的含量(P0.05)。试验至30d,日粮中添加10.0mg/kg纳米硒显著提高血浆T-AOC活性;日粮添加0.3～10.0mg/kg纳米硒能显著降低血浆MDA和血浆NO含量(P0.05)。试验至60d,添加5、10.0mg/kg纳米硒能显著降低GSH-Px活性,添加2.5～10.0mg/kg显著提高NO含量(P0.05)。综上所述,蛋鸡日粮中添加纳米硒至2.5mg/kg是安全的。 |

| Abstract: | The Experiment was conducted to investigate effects of the different level nano-selenium on blood selenium content and antioxidant abilities in hens.Two hundred and eighty eight 42-weeks-old healthy Nong Da 3 hens were randomly divided into six groups,with 48 each group.The hens of the control group were fed the diet adding selenium 0.3 mg/kg as Na2SeO3.The hens in other groups were fed the diet adding selenium 0.3,0.5,2.5,5.0 and 10 mg/kg as nano-selenium,respectively.The results showed that,at 30 day,the blood selenium content was higher in the 2.5～10 mg/kg nano-selenium groups than that of other groups(P < 0.01).The plasma T-AOC activities were higher in the 10 mg/kg nano-selenium groups than that in other groups(P < 0.01).The plasma MDA content was lower in the nano-selenium groups than that in the control group(P < 0.01 or P < 0.05).The Plasma NO content in all nano-selenium groups was decreased(P < 0.01).At 60 day,the blood selenium content was higher in the 2.5,5.0 and 10 mg/kg nano-selenium group than in the control group and 0.3,0.5 mg/kg nano-selenium groups(P < 0.01).The plasma GSH-Px activities were lower in the 5.0 and 10 mg/kg nano-selenium groups than that in the other groups(P < 0.01).The plasma NO content was higher in the 2.5～10 mg/kg nano-selenium groups than that of the other groups.To sum up,it is feasible that the ration in hen is supplemented with the nano-selenium 2.5 mg/kg. |
