摘　　要：选用30头2月龄的贵州剑河白香猪,与剑河九仰黑香猪进行营养需要的比较饲养试验。结果表明,两品种6月龄体重分别为25.00±6.46kg和27.20±8.91kg,均属同一体重类型的小型猪种;剑河白香猪3～6月龄阶段平均每kg增重的饲料采食量为3.735kg,消化能(DE)、粗蛋白(CP)和钙(Ca)、磷(P)的需要量分别为44.33MJ,498g,26.1g,19.4g,饲料利用率较九仰香猪略低而营养需要则较九仰香猪为高。An experiment on nutrient requirement of Jiaohe White Xiang Pig in Guizhou was carried out with 30 two month age pigs. The results indicated that, compared with Guizhou Jianhe Black Xiang pig, the average body weights of two breeds at 6 months old were 25.00±6.46kg, 27.20±8.91kg respectively. They are considered belonging to the same kind of body weight type of small size pig.The feed intake is 3.735kg per kilogram growing body weight at 3～6 months old stage and the requirements of digestable energy (DE), cruse protein (CP), calicium (Ca),phosphorous (P) are 44.33 MJ, 498g, 26.1g, 19.4g successively, and its feed conversion efficiency is a little bit lower but its nutrient requirement per kilogram growing body weight in Jianhe White Xiang pig is somewhat higher than those of in Jianhe Black Xiang pig.
