摘　　要：本试验旨在研究不同比例豆油(n-6 PUFAs)和亚麻油(n-3 PUFAs)对育成期蛋用种公鸡血清、肾脏和睾丸抗氧化性能的影响。选用90只10周龄的‘京红1号’蛋用公鸡随机分成5个处理,每个处理3个重复,每个重复6只鸡。用玉米-豆粕型基础饲料,豆油和亚麻油添加剂量为:2%+0(处理1,对照组)、1.5%+0.5%(处理2)、1%+1%(处理3)、0.5%+1.5%(处理4)和0+2%(处理5)。试验预饲期为1周,正式试验8周。结果表明:(1)随日粮中LO剂量的增加,试验鸡血浆T-SOD、CAT活性和T-AOC能力呈先升高,后降低趋势;第28天,与对照组相比,处理3组T-SOD、CAT和T-AOC活性分别提高了0.38%(P>0.05)、12.31%(P>0.05)和28.24%(P<0.05);第56天,处理3组T-SOD、CAT和T-AOC活性较对照组分别升高了5.43%(P>0.05)、10.63%(P>0.05)和13.76%(P<0.05)。(2)处理3组肾脏T-SOD、CAT和T-AOC活性较对照组分别提高了9.26%(P>0.05)、69.36%(P<0.05)和4.91%(P>0.05);处理3组睾丸T-SOD、CAT和T-AOC活性较对照组分别提高了18.86%(P>0.05)、103.95%(P<0.05)和20.40%(P>0.05)。在本试研究中,育成期蛋用种公鸡日粮中添加不同植物油可提高血浆和组织抗氧化酶活性,增强机体的抗氧化能力。当豆油和亚麻油添加量为1%+1%时,机体抗氧化能力最强。The experiment was conducted to learn the effect of different proportion of soybean oil （n-6 PUFAs） and linseed oil （n-3 PUFAs） on antioxidant capacity of young breeder rooster plasma, kidney and testis. 90 10-week-old breeder roosters were randomly divided into 5 groups, each group had 3 repeats, and 6 roosters in each repeat. Using corn-soybean as meal diets, the ratio of soybean oil and linseed oil were： 2% and 0 （Treatment 1, Control）, 1.5% and 0.5% （Treatment 2）, 1% and 1% （Treatment 3）, 0.5% and 1.5% （Treatment 4） and 0 and 2% （Treatment 5）. The results showed that： （1） with the increasing doses of LO, plasma T-SOD, CAT and T-AOC activity was increasing first, then decreasing; compared with the Control, plasma T-SOD, CAT and T-AOC activity of Treatment 3 increased 0.38% （P〉0.05）, 12.31%（P〉0.05）and 28.24%（P〈0.05）at day 28; compared with the Control, plasma T-SOD, CAT and T-AOC activity of Treatment 3 increased 5.43% （P〉0.05）, 10.63% （P〉0.05） and 13.76% （P〈0.05） at day 56; （2） compared with the Control, T-SOD, CAT and T- AOC activity of kidney of Treatment 3 increased 9.26% （P〉0.05）, 69.36% （P〈0.05） and 4.91% （P〉O.05）; compared with the Control, T-SOD, CAT and T-AOC activity of testis of Treatment 3 increased 18.86% （P〉0.05）, 103.95% （P〈0.05） and 20.40% （P〉0.05）. Under the experiment condition, dietary supplementation with different vegetable oil influences the plasma and tissue antioxidant activity of young breeder rooster, and enhanced the body＇ s antioxidant capacity. The body＇ s antioxidant capacity was the best when the dose of soybean oil and linseed oil were 1% and 1%.
