不同营养水平对兴国灰鹅繁殖性能的影响

Effects of Different Dietary Nutritious Levels on Reproductive Performances of Xingguo Goose

用不同能量及不同蛋白水平的日粮饲喂兴国灰鹅种鹅。试验结果表明:精料补饲低能量、低蛋白组(代谢能10.39MJ/kg、粗蛋白12.97%)的产蛋性能和经济效益,虽略优于高能量、高蛋白组(代谢能12.34MJ/kg、粗蛋白15.23%),但远不如中等能量、中等蛋白组(代谢能11.39 MJ/kg、粗蛋白14.11%)。高能量、高蛋白组虽然有较好的受精率和出雏率,但它的产蛋性能、雏均耗代谢能和雏均耗粗蛋白均劣于中等能量、中等蛋白组。

Three groups of Xingguo goose were fed by daily diet with different nutrhious levels. The testing resuhs showed that the reproductive pefformances and economic benefit of geese in group Ⅱ（ metabolism energy 11,39MJ/kg , coarse protein 14.11% ） were better than those of geese in group Ⅲ （metabolism energy 10. 39MJ/kg , coarse protein 12, 97% ） ,the reproductive performances and economic benefit of geese in group Ⅰ（ metabolism energy 12.34MJ/kg , coarse protein 15.23% ） were the lowest.
