摘　　要：对体重(15.6±0.84)g的异育银鲫(Carassiusauratus gibelio)进行了不同时间的饥饿处理和再投喂恢复生长试验。研究饥饿和再投喂后对其血液生理指标和非特异性免疫指标的影响。研究发现,饥饿使血糖和MDA含量极显著降低(P<0.01),随饥饿时间的延长,SOD活性显著下降后逐渐升高,短期饥饿对ACP活性无显著影响,进一步延长饥饿时间则先升高后显著下降(P<0.01);恢复投喂后,短期饥饿组血糖浓度、SOD和ACP活性均显著上升,中期饥饿组血糖、血红蛋白含量和ACP活性逐渐上升,SOD活性和MDA含量显著下降(P<0.05),长期饥饿组血糖和MDA含量显著低于对照组(P<0.01),ACP活性逐渐恢复到对照水平。结果表明,短期饥饿后再投喂可提高异育银鲫代谢水平和非特异性免疫机能。The effect of starvation periods and re-feeding on blood physiological and non-specific immune parameters in Carassius auratus gibelio （15.6 ±0.84） were studied.Compared to the control,the content of blood glucose and malondialdehyde （MDA） were significantly decreased during starvation （P0.01）.The starvation led an initial significantly decreased superoxide dismutase （SOD） activity followed by increased.The phosphatase （ACP） activity was not effected in short-term starvation,however prolong the starvation,ACP activity increased,but then sharp declined （P0.01）.The content of blood glucose and MDA,the activity of SOD and ACP were significantly increased in short-term starvation group after re-feeding.The content of blood glucose and Hb,ACP activity also increased,however,SOD activity and content of MDA were significantly declined in middle-term starvation （P0.05） after re-feeding.The content of blood glucose and MDA were remarkable declined compared to control,but ACP activity was gradually restored to the control level in long-term starvation after re-feeding.The results showed that short-term hunger and then re-feeding could enhance metabolism and non-specific immune function of Carassius auratus gibelio.
