摘要：

摘要：对体重(15.6±0.84)g的异育银鲫(Carassius auratus gibelio)进行了不同时间的饥饿处理和再投喂恢复生长实验。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。

Abstract:

Abstract: The effect of starvation periods and refeeding 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 (P <0.01 ). 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 (P<0.01). 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（P<0.05）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 .
