%X 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 .
