Abstract

Food and energy requirements of captive barn owls were determined at 5, 15 and 25 degrees C. Food consumption, gross energy intake, dry matter intake, and existence metabolism increased as ambient temperature decreased. Barn owl energy assimilation efficiencies at the three test temperatures were approximately 78%. An increase in bioenergetic parameters might be anticipated when a bird is cold-stressed and must increase its metabolism for thermoregulation.

摘要

在5摄氏度、15摄氏度和25摄氏度的环境下测定了圈养仓鸮的食物和能量需求。随着环境温度降低，食物消耗量、总能量摄入量、干物质摄入量和基础代谢率均增加。在这三个测试温度下，仓鸮的能量同化效率约为78%。当鸟类受到冷应激且必须提高新陈代谢以进行体温调节时，生物能量参数可能会增加。
