摘要
在2．0，11．5，16．5，20．5℃温度下，笼养黑琴鸡（Lyrurustetixbaikallensis）能量平衡实验结果表明，其总摄入能、排泄能、维持能、粪便热值均随温度的升高而降低；食物利用率与温度之间的相关不显著，但具有随温度升高而增大的趋势．在165℃时，黑琴鸡的总摄入能、维持能显著低于其他温度组．对黑琴鸡而言，16．5℃是否最适温度。
At 2.0, 11.5, 16.5 and 20.5℃, the energy balance of caged black grouse was measured. The result is: the gross energy consumption, excrement energy, maintain enery and excreta enery increase with trising temperature. There are no significant differences in food usage at various temperatures, but there is a trend that the food usage increaes with in creasing temperature. There is a minimum gross energy consumption, maintain energy at 16.5℃. Further study should be called out to determine whether or not 16.5℃ is the optimal temperature for black grouse (Lyrurus tetrix baikallensin).
