早籼稻糙米代替玉米育肥猪的增重效果

选用个体重 30kg左右 ,日龄相近的“杜长大”育肥猪 6 0头 ,随机分为 4组 ,每组 15头 ,公母比例相同且均阉割去势过。Ⅰ组为对照 (玉米 47% ,早稻糙米为 0 ) ,ⅡⅢⅣ组日粮分别用早籼稻糙米 40 %、70 %、10 0 %代替玉米进行 6 0d饲养。结果 4个组的平均个体日增重分别为 787、788、796、80 1g ,各组间差异不显著 (p >0 .0 5 )。结果表明 ,用早籼稻米代替部分或全部玉米作为育肥猪日粮中的能量饲料对育肥猪增重无不良影响 ,是实现粮食转化的可行方法。

Study on the Effect of Husked Rice Instead of Maize on Pig Growth

Duchangdai Pigs with same day-old and 30 kg weight divided into four groups were experimented in the feed application. Group I was the control group with the feed containing 47% Maize, and Group Ⅱ,Ⅲ and Ⅳ was with the feed containing 40%, 70% and 100% husked rice instead of maize for 60 days application. The result indicated that the increasing weight of individual pig per day of four groups was 787g, 788g, 796g and 801g respectively and there were not significant differences among four groups (P>0.05). Pig growth was normal with using the feed containing husked rice partially or completely.
