玉米秸型配合饲料饲喂生长育肥鹅的试验

Experiment on Fatting Goose by Feed Corn Stem Type Compound Feedstuff

在舍饲条件下 ,完成了玉米秸型配合饲料饲喂生长育肥鹅试验。试验期为 60d ,玉米秸在配合饲料中的比例为 2 0 %、30 %和 4 0 %。试验鹅 90日龄体重对照组为 360 7g ,试验A组( 2 0 % )为 312 0g ,试验B组 ( 30 % )为 2 952g ,试验C组 ( 4 0 % )为 2 4 0 0g ;试验期相应增重为 3170、2 616、2 4 4 5和 1898g ;配合饲料的料重比相应为 2 4∶1、2 8∶1、3 0∶1和 4 6∶1;每只鹅的纯利润相应为 13 4 1、11 36、10 83和 6 2 0元。随玉米秸用量的增加 ,以上各项指标均降低。但玉米秸在 30 %以内时 ,饲料成本利润率为 1 4 9、1 55和 1 64,呈增加趋势。

An experiment on corn stem_type compound feed in growing goose was complished under the condition of house feeding.The experiment was designed as control,experiment A,B,and C with two monthes.Corn stem meal in compound feed were 20,30 and 40 percent for the experiment groups in response.Live weight of experiment goose were 3 607 g,3 120 g,2 952 g and 2 400 g by the age of 90 days correspondingly.Weight gains were 3 107 g,2 616 g,2 445 g and 1 898 g in response.Efficiency of compound feed were 2.4∶1,2.8∶1,3.0∶1and 4.6∶1.Pure profit were 13.41,11.36, 10.83 and 6.20 yuan in PMB.All the index above went down with the increase of corn stem proportion.But profit rate of feed cost increased as 1.49,1.55 and 1.64 when corn stem were within 30 percent in compound feed.
