| 摘 要： | 研究了黑羽型番鸭不同生长期的能量代谢、饲料能量摄入及其同化率,结果表明:雏鸭的代谢本与体重呈强的线性负相关(鸭,r=-0.88,t=4.9>t_(0.01);鸭,r=-0.855,t=4.36>t_(0.01)),不同周龄雏鸭的摄食量、能量摄入、可代谢能量和生长能量的增长值与体重的增长情况基本一致,能量同化率除1周龄(42.66％)较低外,其余各周龄均保持在82.44～90.52％之间。

| Abstract: | Energy metabolic and energy intake rates, as well as energy assimilation ratios of Gairina maschata in different growth periods have been investigated. The results show that the ducklings' metabolic rates are negatively correlated to body weights, while their daily metabolic energy consumptions are positively correlated to body weights. In growing ducklings, the relative increasing rates of feed and energy intake, metabolizable energy, daily metabolic energy consumption, and growth energy are parallelel to the relative body weight gain rates. The daily gross energy assimilation ratio of growing ducklings are considerably stable within the range of 82. 44-90. 52, with the only exception at first week, which is 42. 66%. |
