不同能量水平对蓝孔雀生长速度及繁殖性能的影响

采用单因素3水平设计方法对蓝孔雀进行饲养试验，研究不同能量水平对蓝孔雀生长速度及繁殖性能的影响。试验选取2月龄蓝孔雀肉鸟90只，种鸟45只，各分为3个组，每组设3个重复，以能量水平为试验因子，肉鸟日粮代谢能水平为：11．09MJ／kg、11．53MJ／kg和12．24MJ／kg，种鸟日粮代谢能水平为11．33MJ／kg、12．21MJ／kg和12．85MJ／kg，饲养期为5个月。结果表明，肉鸟的日粮代谢能为11．53MJ／kg时其生长性能表现最佳，种鸟日粮代谢能为11．21MJ／kg时其产蛋性能最好。

Effects of Dietary ME Content on Grouth and Reproductive Performance of Blue Peafowl

The purpose of this study was to determine the effect of dietary metabolizable energy （ME） content on growth and reproductive performance of blue peafowl. 90 young peacock and 45 breeding peafowl were chosen and divided randomly into 3 groups respectively in triplicate for each group. The trial was designed in a single factor of 3 levels according to ME content in diets. The ME contents in diets were 11.09MJ/kg, 11.53 MJ/kg and 12.24 MJ/kg for young birds and 11.33 MJ/kg, 12.21 MJ/kg and 12.85 MJ/kg for breeding birds respectively. Results of this trial showed that the young birds consumed the diet with 11.53MJ/kg of ME content had the best growth performance and the breeding had better reproductive performance when they were fed diet with 11.21MJ/kg of ME.
