摘要

动物代谢的主要能源物质为脂肪、碳水化合物和蛋白质，前两者在体内可以完全氧化而生成二氧化碳和水，而蛋白质的代谢终产物是氨、尿素和其它含氮化合物，它们是含能物质。鱼类蛋白质的含氮代谢物质主要通过鳃排出，少量通过尿液排出(Beamish et al.,1984)，这种排泄物的能量损失也称为非粪便失能。鱼类非粪便失能的测定方法主要是直接测定鱼的氨及尿素排泄量，然后通过氨及尿素的含能量来计算；另一种方法是通过氮收支方程来间接估计排泄物的能量损失(Gerking，1955；Savitz，1971； Savitz et al.，1977；Lwata，1970；Porter et al.，1987)，Braaten(1979)，Bower等(1980)，Cameron等(1983)， Brafield(1985)和Knights(1985)对鱼类排泄量的各种测定方法进行了介绍和综述。本研究是应用氮收支方法来间接估算黑鲷的排泄能损失。这对于探讨鱼类对蛋白质的利用效率及代谢产物对养殖水环境的影响都具有一定的指导意义。

Abstract

Feeding-growth experiments on young black porgy (Sparus macrocephalus B., 4.17-69.05g initial weight) were carried out at four ration levels from starvation to satiation and four temperatures ranging from 14.8℃ to 26.8℃. Nitrogen excretion was calculated from the nitrogen budget (CN=FN+UN+GN). At starvation, the energy losses in excretion correlated to body weight in multiple function and the coefficient b ranged from 0.56-0.77. In feeding fish, the relationships between excretion and food consumption were positive linear functions. Stepwise regression yielded the prediction model for energy excretion as: U=0.0098+0.0539C+0.0087W-0.0003WT (r2=0.932, P<0.0001)
