摘要
选用体重约15 kg、35 kg、70 kg三个阶段的三元杂交(杜×长×大)生长肥育猪36头、32头、32头,每个阶段按性别、体重随机分为两组,一组作为对照组,饲喂玉米-豆粕型日粮;另一组为试验组,试验组日粮用豆粕替代品(替宝100)取代对照组中部分或全部豆粕。15 kg阶段试验组比对照组日增重提高2.25%,饲料报酬提高4.50%。35 kg阶段试验组比对照组日增重提高11.69%,饲料报酬提高6.34%(P<0.05)。70 kg阶段试验组比对照组日增重提高7.92%,饲料报酬提高7.97%(P<0.05)。
With an initial body weight of about 15 kg, 35 kg and 70 kg, 36, 32 and 32 three -way -cross growing -finishing pigs ( Duroc × Landrace × Large Yorkshire} were selected respectively. At each stage, the pigs were randomly divided into two groups based on sex and body weight. One was fed a corn - soybean meal diet as a control, and the other Tibao 100 as a test, a soybean meal substitute that replaced some or all soybean meal in the control diet. At the 15 - kg stage, the test group had a daily weight gain increase of 2.25% and a feed efficiency improvement of 4.50% compared with the control group. At the 35 - kg stage, the test group had a daily weight gain increase of 11.69% and a feed efficiency improvement of 6.34% ( P 〈 0.05 ) compared with the control group. At the 70 -kg stage, the test group had a daily weight gain increase of 7.92% and a feed efficiency improvement of 7. 97 % ( P 〈 0.05 ) compared with the control group.
