Abstract: Twenty-four haemal physiological parameters in Ba-ma mini-pigs （♂20，♀30）from 4 to 12 months of ages were determined and analyzed. The results showed that no significant difference were observed between sex in haemal physiological parameters in Ba-ma mini-pigs. Whereas most of the detected items were different among the different months of ages （P＜0. 05 orP＜0.01）. Moreover, the values of almost half of the items showed increasing or decreasing with the increase of months of ages. The majority items of Ba-ma min-ipigs were similar to those of common pigs, and 14 haemal physio-logical parameters of Ba-ma mini-pigs were similar to those of human beings，for cxample, Neutrophilic granulocyte, Lymphoyte, Monocyte, Eosinophil, Basophilic cell, Hemohlobin concentration etc. It is concluded that there are some sinilarities in physiological charactcrs betwcen Ba-ma mini-pigs and human beings.
