Abstract: Objective To measure the body weight,weight of major organs,and organ coefficient,in new-born and one-month old Guizhou miniature pigs and analyse the correlation.Methods 20 new-born Guizhou miniature pigs with equal of the sexes and 20 Guizhou miniature pigs of age of one month,with equal of the sexes were used in this series.The body weight,weight of major organs,and organ coefficient of new-born and one-month old Guizhou miniature pigs were measured and compared,then the growth rate of organ coefficient was worked out.Results The body weight and weight of major organs were increased with age.Some organs coefficient were increased with age,and some organs coefficient were decreased with age.Conclusion These results filled in the gaps in the some physiological indexes of Guizhou miniature pig,and provided basic data for relative researches.

摘要： 目的测定幼龄贵州小型猪脏器重量、脏器系数的生物学特性指标。方法选用初生(0 d)和一月龄(30 d)普通级贵州小型猪各20只,雌雄各半,分别测定体重和10个脏器重量,计算脏器系数。结果雌雄贵州小型猪初生组体重、肝重量、肾重量、胃系数差异均有极显著性(P<0.01),胃、心重量有显著性差异(P<0.05),而一月龄组雌雄体重和脏器重量均无显著性差异(P>0.05),肺系数有极显著性差异(P<0.01)。结论雌雄幼龄贵州小型猪的体重、肝重量、胃重量、心重量、肾重量、胃系数、肺系数具有差异。
