摘　　要：目的研究西藏小型猪早期生长发育的规律。方法对本基地F1代西藏小型猪的体重、体长、胸围、体高、体温、呼吸频率、心率及血液生理生化指标进行了测定。结果西藏小型猪体型小,生长性能稳定,生长速度与原产地西藏小型猪基本一致;西藏小型猪的体温、呼吸次数和心率与原产地西藏小型猪相近,且雌雄之间差异不显著(P>0.05);F1代雌雄间除嗜碱性粒细胞、单核细胞数和尿素氮外其他指标也基本一致,大部分指标与人接近。结论由于西藏小型猪体型小、生长性能稳定,血液生理生化值与人类相近,因而是理想的医学研究用实验动物。Objective To characterize the growth and development traits of the first generation young Tibet mini-pigs. Methods The measurements of body weight, body length, chest girth, wither height, rectal temperature, respiratory rate, heart rate, blood physiological and biochemical traits of the first generation young Tibet mini-pigs were carried out at a breeding farm in Guangzhou. Results The Tibet mini-pigs in Guangzhou area had smaller size, stable growth performance and the same growth rate as that reared in original area. It demonstrated that rectal temperature, respiratory rate and heart rate were similar among the first generation and generations raised in original area. Meanwhile, no significant difference was found between boar and gilts （ P 〉 0.05）. Except basophils, monocytes and serum BUN, other parameters of the F1 male and female pigs were also approximate and close to that of human beings. Condusion The present study indicates that Tibet mini-pig is an ideal experimental animal for medical researches due to its smaller size, stable growth performance and physiologically and biochemically closely related to human beings.
