摘　　要：为了探讨在玉米—豆粕型日粮中小麦代替部分玉米并添加酶制剂对育肥蛋公雏的饲喂效果，我们用１ 日龄新罗曼蛋公雏为试验动物， 用小麦代替玉米用量的１／３ 和２／ ３ 并添加好特美 Ｘ 或华芬酶Ⅰ，试验期７０ 天。结果表明：小麦代替不同比例的玉米并添加酶制剂后， 对其成活率和采食量无影响， 但腿部色泽随玉米用量减少黄色度下降。用小麦代替玉米用量的１／ ３ 和２／ ３ 并添加好特美 Ｘ ， 对育肥蛋公雏的日增重、饲料报酬有促进作用， 经济效益也好于玉米—豆粕型日粮， 但发现用小麦代替玉米用量的２／ ３ 时腿部色泽较浅， 影响商品性。用小麦代替１／ ３ 和２／ ３ 的玉米并添加华芬酶 Ｉ， 前者有利于育肥蛋公雏的增重和提高饲料报酬， 后者可导致日增重和饲料报酬下降，２ 种代替比例并添加华芬酶 Ｉ 经济上均不合算。因此目前情况下， 综合考虑， 以小麦代替１／ ３ 玉米并添加好特美 Ｘ 在生产上有推广意义。Taking ld age new Roman eggtype cocklets as test animal and replacing 1/3 and 2/3 amount of corn with wheat while adding haotemeix or Huafeng Enzyme Preparation of the same time ,We tested 70d to study the feeding effects of eggtype cocklets with a corn-soybean meal type ration in which part of corn indigrent was replaccd with wheat and some enzyme preparation was added The results showed that replacing different rate of corn with wheat while adding enzyme preparation had no effect on survival rate and feed consumption ,but leg yellow condensity faded whilt the amount of corn used in the ration decreased replacing 1/3 or 2/3 corn with wheat while adding Haotemei X increased daily gain and improved feed conversion rate of egg-type cocklets,ecomic benefit better than feeding cornsoybean meal ration ,but the yellow leg became pale when 2/3 corn was replaced with wheat ,which would affect the cocklet's commodity value. Replacing 1/3 corn with wheat while adding Huafen Enzyme Preparetion I could improve weight gain and feed conversion race ,while replacing 2/3 corn with wheat and adding Huafen Enzyme Preparation I caused the decline of daily gain and feed conversion rate ,but adding Huafen Enzyme Preparation I in both the two cases was not worth while econmicly, Considering comprehensively ,replacing 1/3 corn with wheat while adding Haotemei X is worth spreading in animal prodution at present.
