摘　　要：目的测定融水小型猪F1代体重和体尺。方法选取F1代融水小型猪83头（雌性48头,雄性35头）,测定初生至12月龄的体重、体长、体高、胸围、胸宽、胸深、管围、腿围、嘴裂长度共9个生长发育指标,并应用SPSS统计软件和Logistic非线性生长模型进行分析。结果融水小型猪F1代的初生体重雌雄分别为0.61±0.14kg和0.55±0.13kg,6月龄体重雌雄分别为17.21±5.20kg和16.35±5.23kg,12月龄体重雌雄分别为26.97±6.49kg和26.53±5.65kg。雌雄比较,9项指标所测结果接近,除了初生体重和体长、10月龄胸宽有差异（P〈0.05）,其余指标同月龄雌雄之间均无明显差异。应用Logistic模型分析,体重生长拐点在5~6月龄间,体长和腿围生长拐点在2~3月龄间,体高、胸围、胸宽、胸深、管围和嘴裂长度的生长拐点在1~2月龄间。结论融水小型猪F1代成年体重轻,性情温顺,具备培养成实验用小型猪基本条件。Objective To measure the body weight and body size of the F1 generation in Rongshui miniature pig （ RMP ）. Methods 83 F1 generations of RMPs （48 females and 35 males） were selected randomly. 9 traits included body-weight, body-length, body-height, chest-circumference, chest-breadth, chest-depth, circum of pastern, girth of leg and rictus were measured, and analyzed statistically by SPSS statistical software and Logistic nonlinear growth analysis model. Results In the F1 generations of RMP, the weights of birth day,6＇hmonth and 12th month of female and male were 0.61±0.14 kg and 0.55±0.13 kg, 17.21±5.20 kg and 16.35±5.23 kg, 26.97±6.49 kg and 26.53±5.65 kg respectively. There was no difference significantly between the genders of the 9 measured traits except for born-weight, born-length and chest-breadth in 10th month （ P 〈 0. 05 ）. According to the analysis in Logistic model, body-weight inflection point was between 5th -6th month, body length and girth of leg inflection points were 2nd ~ 3th month, while inflection points of other traits were It 2ha month. Conclusion The F1 generations of RMP showed low mature body weight and sweet temper. It should be breed as good laboratory miniature pig.
