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。
Hucho tajmen juveniles were disposed with the starvation for7 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 levels decreased sharply （ P 〈 0. 05 ） after starvation for 7 d and then kept stably. The concentration of total protein, albumin and globin decreased significantly after starvation for 21 d, 28 d and 7 d respectively. The scram lriglyceride and the total cholesterol decreased sharply（P 〈 0. 05 ）after starvation for 7 d and 14 d. The ALT and AST decreased significantly（ P 〈 0.05 ）after starvation for 14 d. The AKP decreased significantly （P 〈 0. 05 ） after starvation for 7 d. The concentrations of Na^＋ and Cl^- decreased significantly（ P 〈 0. 05 ） after starvation for 7 d, then increased significantly （ P 〈 0. 05 ） again after starvation for 14 d. The concentration of Ca^2 ＋ increased sharply （ P 〈 0. 05 ） after starvation for 14 d, then decreased significantly（ P 〈 0. 05 ） after starvation for 28 d. The concentration of K^＋ increased after starvation, but there were no differences among the groups. Alter re-feeding, the blood indices all recovered with different dedree.
