Abstract
Abomasal motility was observed by needling to acupoints for 20 min. The acupoints used were guan yuan yurt da chang yurt dei yup pi yurt and hou hoi. The acupoint which showed the increase of the largest wave type was pi yu and the increase of wave type was observed 20 minutes after needling in hou hoi and dei yu acupoint. But there was no effect on abomasal motility after needling to guan yuan yu and da chang yu. On the other hands change in amplitude of the abomasal contraction after needling to these acupoints was not abserved. These results indicate that stimulation to pi yu acupoint would be the most useful to increase the abomasal motility.
