Abstract: Abstract: Objective To discuss the suitable training bouts for Bama mini-pigs，and the treadmill exercise parameters of Bama mini-pigs． Method The exercise training last consecutive 4 weeks，once a day． Speed was progressively increased by 0. 3km /h or its multiples depending on the ability of the the Bama mini-pigs until they can not tolerance． The speed and duration and the changes of vital signs before and after the treadmill exercise were measured． The eight Bama mini-pigs used were 9 － month old，male and castrated，and with the mean body weight of ( 53. 46 ± 2. 52) kg． Ｒesult The 8 Bama mini-pigs could run smoothly after 1 week training． After the 3 － week process of skilled treadmill exercise，training bouts included a slow acceleration，a rapid acceleration，a rapid deceleration，and a slow deceleration，with the maximal speed of ( 3. 4—7. 5 ) km /h，the longest duration of 1 530 seconds，and the average duration of 735. 26 seconds． The ear temperature，crissum temperature，heart rate，respiratory rate and systolic pressure incresed significantly． while the respiratory rate was significantly increased after the 3 － week skilled treadmill exercise，the changes of the others of vital signs under the rest state were without statistical significance． Conclusion The training bouts of Bama mini-pigs included a slow acceleration，a rapid acceleration，a rapid deceleration，and a slow deceleration． Nevertheless， it needs further research whether the daily maximum speed and duration can reach the level of the foreign swines．
