摘要： 选用39周龄岭南黄品种肉用母种鸡240只,按照饲养试验要求分成2组,每组3个重复,分别 饲喂添加0 。30 mg.k g-1硒水平的亚硒酸钠和 DL-硒代蛋氨酸日粮 ;种蛋按重复分别孵化后,初生雏鸡 各选60只,共计360只,饲喂不加硒的相同日粮56 d,研究母种鸡补充不同硒源对后代肉鸡硒沉积、抗 氧化指标及生长性能的影响 。结果表明 :与亚硒酸钠组比,硒代蛋氨酸组显著提高了初生雏鸡、肉成鸡 肝、肾和肌肉组织、雏鸡胸腺、肉成鸡血清及种蛋的硒含量( P<0.0 1) ;提高了初生雏鸡肌肉 GSH-Px、 SOD和肾脏 SOD活力( P<0.0 5)、肌肉和肝脏 T-AOC及肾脏 GSH水平( P<0.0 1),降低了肌肉和胰 脏 MDA含量( P<0.0 5) ;增强了肉成鸡血清和肌肉 GSH-Px活力( P<0.0 1)、血清 SOD活力、胰和肌肉 T-AOC( P<0.0 5) ;降低了后代肉鸡死亡率和料质量比( P<0.0 5) 。上述结果提示,母种鸡补充 DL-硒代 蛋氨酸同比亚硒酸钠能提高种蛋及后代肉鸡组织硒含量,增强后代机体抗氧化功能,降低其死亡率,有 利于生长并提高饲料转化率 。
Abstract: A total of 240 39-week-old Lingnan Yellow broiler breeders were randomly allocated to two groups,which were fed with the basal diet containing0.0 4 mg.k g-1 Se with the supplement of0.3 0 mg Se.k g-1 sodium selenite (SS) and DL-selenomethionine (SM),respectively,and each group was replicated three times with forty birds per replicate . The eggs were collected of each replicate and hatched . The total360 chicks were fed with the basal diet containing 0.0 4 mg.k g-1 Se without other selenium supplementation for56 days,to evaluate the effects of different maternal selenium on selenium deposition,antioxidant indices and growth performance of the progeny .Results indicated that,compared with the SS group,SM group increased significantly the selenium contents in liver,kidney,muscle tissue of the1 and 56-day-old progeny,as well as the selenium contents in thymus of the 1-day-old chicks,serum of the 56-day-old chicks and eggs ( P <0.0 1) . Compared with the SS group,in the 1-day-old chicks of the SM group,the activities of GSH-Px in muscle and SOD in muscle and kidney increased significantly ( P < 0.0 5),and the T-AOC in muscle and liver and the level of GSH in kidney also increased significantly ( P<0.0 1),while the content of MDA decreased significantly ( P<0.0 5) in muscle and pancreas;and in the56-day-old chicks of the SM group,the activities of GSH-Px in serum and muscle,SOD in serum,T-AOC in muscle and pancreas increased significantly ( P<0.0 5),while the death rate and the ratio of feed to mass decreased significantly ( P <0.0 5) . The results above indicate that DL-SM is more effective in improving the tissue selenium contents and antioxidant capabilities,decreasing the death rate of the offspring broilers,helping to their growth and increase of the feed conversion rate than SS,when the broiler breeders were fed with different selenium sources .
