Effects of Electroacupuncture on Motility of the Rumen and Abomasum of Goats

전침자극(電針刺戟)이 염소의 제일(第一) 및 사위운동(四胃運動)에 미치는 영향

Ruminal and abomasal motility after electroacupuncture was investigated in normal goats and in goats with induced hypocalcaemia. Electroacupuncture was performed with a current of 1 volt and 3Hz at the acupoints of Tien Ping(positive) and Pai Hui(negative) for 30 minutes. The adequate range of electroacupuncture stimulation for goats was 1 to 2 volt and 2 to 3 Hz. After electroacupuncture stimulation in normal goats, rates of rumen and abomasal contractions were not changed or were slightly increased, but amplitudes of rumen and abomasal motility markedly increased. The effects of electroacupuncture stimulation lasted from about 10 minutes to 30 minutes after the end of electroacupuncture. The amplitudes of rumen motility were increased by the administration of bethanechol chlorids in goats. Ruminal contractions were not influenced by electroacupuncture following atropine sulphate. The rates of rumen and abomasal movements were not changed, but its amplitudes were reduced by inducing hypocalcaemia in goats. Motilily of the rumen and abomasum was not accelerated by electroacupuncture in goats with induced hypocalcaemia.
