小麦青稞型日粮代替玉米型日粮饲喂种鸡的效果

为了用当地饲料资源代替依赖外省调入、价格昂贵的玉米，我们用当地产小麦、青稞为主组成日粮（试验组），与玉米型日粮（对照组）对比，在代谢能与粗蛋白质水平基本一致的情况下，对京白种鸡进行饲喂试验。试验结果：两组在成活率、产蛋率、孵化率、平均蛋重均无显著差异（Ｐ＞０．０５），而经济效益试验组明显优于对照组，平均每只母鸡多盈利３．９６元。结果表明，小麦青稞型日粮代替玉米型日粮完全可行。

The Effect of Substituting Wheat- nudebarley Diet for Maize Diet in Breeding Chicken Feeding

In order to malse use of local feed resources such as wheat and nudebarley , Wecarried out this feeding experiment, in which the Beijing Bai layer were used and given twoisocalovic and isonitrogenous diets mainly composed of wheat,nude barley ( experimentalgroup )and maize(control group). No significant difference between the two groups in livabili-ty,laying rate,hatchability and mean egg weight was found. However ,the economic benefit ofthe experimental group was significanily high as compared with that of the control group,theprofit of each hen in experimental group increased by 3. 96 yuan RMB. The experiment com-firmed that maize diet may be replaced by wheat-nude barley diet.
