摘  要:试验旨在研究玉米DDGS替代豆粕对草鱼(ctenopharvngodon idellus)幼鱼生长性能、血清生化指标和免疫指标的影响,选用360尾初重为(5.52±0.09)g的草鱼苗,随机分为6个处理组,分别设为D0、Dl、D2、D3、D4、D5组,每个处理组设3个重复,每个重复20尾,分别投喂用0、10%、20%、30%、40%、50%玉米DDGS替代豆粕的6种等氮饲料,饲养3周:结果表明:玉米DDGS添加量在30%以下时对草鱼生长性能没有显著影响(P>0。05);添加量在40%~50%时草鱼生长性能显著下降(P<0.05),与对照组比较各试验组血清生化指标无显著差异(P>0.05);免疫指标试验组一氧化氮、超氧化物歧化酶与对照组相比无显著差异(P>0.05);总抗氧化能力50%组显著高于0、10%和30%组(P<0.05);20%组丙二醛含量显著低于对照组(P<0.05);试验组碱性磷酸酶活性与对照组相比有显著差异(P<O.05)An experiment was conducted to study the effects of dietary content of distillers dried grains with soluble (DDGS) on growth perfornlanee, serum biochemical indexes and immunity in Ctenopharyn godon idellus. 360 trail of Ctenopharyngodon idellus [(5.52±0.09) gl were randomly allot'areal into 6 groups, one group contained three replication. After three weeks feeding, the results showed that groups below 30% of DDGS had no significant difference on growth performance (P〉O.05). Adding 40% to 50% of the amount can reduce sinificantly the growth pertbrmanee.Compared with the control group, the serum biochemical index had no significant diference (P〉0.05). Nitric oxide (NO) and superoxide dismu tase (SOD) had no significant difterenee compared with those of the control group (P〉O.05). Total antiox idative capacity (T-AOC) in the 50% group was sinifieantly higher than those in O, 10C% and 30% group (P〈O.05). Malondiahlehyde (MAD) in the 20% group was sinificantlv lower than those in the conlrol group (P〈0.05).
