Objective To measure the indexes including body weight, organ weight and organ coefficient in outbred Diannan mini-pigs. Methods 24 outbred Diannan Mini-pigs in 5-6 months (12females and 12 males) were chosen, and the body weight and 17 organs' weight were determined, then the organ coefficients were counted. The organ coefficient between males and females were compared. The correlation and regression analysis was performed. Results Between female and male outbred Diannan mini-pigs in 5-6 months, the lung weight showed obvious difference ( P < 0.05). The coefficient of lung and submandibular gland had obvious difference (P<0.05). Linear analysis showed that there were obvious linear relations between body mass and the weight of heart, spleen, pancreas, parotid in male mini-pigs. There were linear relation between body weight and heart, uterus in female. Conclusion Differences of organ coefficient are not significant between males and females, and there are linear correlation between body weight and some organ weight.%目的 测定5～6月龄滇南小耳猪体重、脏器重量,并对其进行相关分析.方法 选用5～6月龄封闭群滇南小耳猪24只,雌雄各半,分别测定体重和17个脏器和腺体重量,计算脏器系数,通过SPSS软件进行脏器系数的性别间比较和脏器重量与体重间的相关性与回归分析.结果 封闭群小耳猪脏器重量雌雄间仅肺脏差异有统计学意义(P＜0.05)；脏器系数雌雄间仅有肺系数和颌下腺系数差异有统计学意义(P＜0.05).体重和脏器重量相关分析表明,雄性滇南小耳猪体重与心、脾、胰腺、腮腺有相关性(P＜0.05)；雌性的体重与心、膀胱有相关性(P＜0.05),进一步的回归分析显示,雄性的心、脾、胰腺、腮腺,雌性的心、膀胱与体重呈线性相关(P＜0.05).结论 封闭群滇南小耳猪主要脏器系数性别间差异小,其体重与某些脏器重量存在一定的线性关系.
