摘要
选用192只23周龄产蛋良好的海兰褐商品蛋鸡探讨日粮中添加不同比例的酶解羽毛粉对蛋鸡生产性能的影响，共计3个处理，每个处理4个重复，每个重复16只鸡，三层阶梯式笼养，自由采食、饮水，进行饲养试验。试验期为30天。对各处理组的蛋鸡日只耗料量、产蛋率、日只产蛋量、平均蛋重、料蛋比的记录数据进行统计分析，研究用羽毛粉代替部分植物蛋白饲料（豆粕）的可行性。结果表明，日粮中添加2．5％、5％酶解羽毛粉对蛋鸡日只耗料量、产蛋率、日只产蛋量、平均蛋重、料蛋比五项指标均无显著影响（P〉0．05）。因此，在蛋鸡日粮中用羽毛粉代替部分植物蛋白饲料原料是经济的。可行的。大力开发利用羽毛粉，对解决我国目前蛋白资源紧缺的状况具有重要的理论和实践意义。
Selecting 192 chickens,23 week ages and produce good eggs Hiran browncommodity layer to discuss the influence to the layer production performance , increasing different proportion of the enzymolysis feather powder to the ration , total 3 processing, each processes 4 repetitions, each duplicates 16 chickens, three steps and ladders types raising in cages, taking food,water freely . The experi.nental time is 30 days. Statistical analysis the data according to the date consumes of every dealed layer, the laying rate, date egg quantity, heavy of average egg, feed/egg, and studies the feasibility replacing the oartial albumen feed with the feather powder （bean cake） . The result indicated that increases 2.5% , 5% enzymolysis feather powder to the ration, it has not remarkable influenee （ P 〉 0.05） on the five targets ineluding the date eonsumes of every dealed layer, the laying rate, date egg quantity, heavy of average egg, feed/egg. There- fore, replacing the partial plant albumen feed raw material in the layer ration with the feather powder is economical, feasible. Developing and using feather powder vigorously have the important theory and the practice significance to solves the protein resources scarce of our country at present.
