【摘要】 用两种单宁含量不同的杂交种高粱“原杂10号”(红色,含单宁0.92％,下称HT-高粱)和“渤杂1号”(白色,含单宁0.11％,下称LT-高粱)代替玉米-豆饼日粮中玉米的0,25,50,75和100％,饲养7～42日龄Hubbard肉用小公鸡,结果指出:用HT-高粱代替肉鸡日粮中的玉米,代替量不应超过50％,否则鸡的增重和饲料利用率降低;用LT-高粱,代替量从25％到100％,均可获得与玉米为能量饲料大致相同的增重和饲料报酬。更多还原

【Abstract】 High-tannin ( HT ) containing 0.92% tannin and low-tannin ( LT ) containing 0.11% tannin sorghums were used in different rations to replace 0 , 25, 50, 75 and 100% of corn fed 7-42 day old Hubbard male broilers, and the body weight, feed intake and feed conversion were compared with the control ration using corn only. It showed that corn can be at all replaced by LT-sorghum, however, for the HT-sorghum, rate of growth and feed efficiency were lowered if the replacement of corn was higher than 50%.更多还原
