| 摘 要： | 将哲罗鱼(Hucho taimen)幼鱼进行7 d、14 d、21 d和28 d的饥饿处理后恢复投喂,研究饥饿和再投喂对其血液生理与生化指标的影响,各组实验期为56 d。结果显示:饥饿过程中哲罗鱼幼鱼血液红细胞数、血红蛋白和白细胞数均在饥饿14 d后显著上升(P<0.05),21 d后则开始下降;饥饿7 d后血糖浓度显著下降(P<0.05),14 d后趋于稳定;总蛋白、球蛋白和白蛋白均呈下降趋势,分别在饥饿的第21天、28天和7天后与饥饿前差异显著(P<0.05);甘油三酯和总胆固醇分别在饥饿7 d和14 d后显著下降(P<0.05);谷丙转氨酶和谷草转氨酶均在饥饿14 d后显著下降(P<0.05);碱性磷酸酶在饥饿7 d后显著下降(P<0.05);饥饿7 d后Na+和Cl-浓度显著下降(P<0.05),14 d后均显著回升(P<0.05);Ca2+浓度在饥饿14 d后显著升高(P<0.05),28 d后显著降低(P<0.05);K+浓度在饥饿后升高,但与饥饿处理前比较无显著性差异。恢复投喂结束后,哲罗鱼幼鱼血液的各项生理生化指标均有不同程度的恢复。

| Abstract: | Hucho tajmen juveniles were disposed with the starvation for 7 d,14 d,21 d and 28 d,then resumed to refeed for 49 d,42 d,35 d and 28 d respectively.The effects of starvation and refeeding on the physiological and biochemical indices of the blood of H.tajmen juveniles were studied in this experiment.Results were revealed as following:The numbers of the red cell,white cell and the hemoglobin increased obviously(P<0.05)after starvation for 14 d and then decreased after starvation for 21 d.The serum glucose lev... |
