The ileus is classified as a decrease or absence of gastrointestinal motility and often leads to death of the animal. It is known that the use of electroacupuncture has influence on the gastrointestinal motility in humans and animals. The aim of this study is to evaluate the effect of electroacupuncture on the intestinal motility and transit of healthy horses. Eight equines will be distributed in the following groups: Group Metoclopramide (GM), in which 0.04mg/kg of metoclopramide, IM, will be administered in two moments, with an interval of one hour between them; Group Electroacupuncture (GE) in which electric stimulation will be performed in the acupoints E21-E25 and E36, in a dense-dispersed alternating frequency (F1 = 3 Hz; F2 = 10 Hz) for 15 minutes in two moments, with an interval of one hour between them; Group False Electroacupuncture (GF), in which electroacupuncture will be performed in the same way, but in false points (sham). Intestinal motility evaluations, through auscultation and ultrasonography, will be performed at T0 times (immediately before treatment, considered the baseline parameter), T1 (20 minutes after the start of the first treatment), T2 (20 minutes after the start of the second treatment), T3 (60 minutes after T2), T4 (120 minutes after T2), T5 (180 minutes after T2), T6 (240 minutes after T2) and T7 (360 minutes after T2). The evaluation of intestinal transit will be performed using the chromium oxide marker. The hypothesis is that electroacupuncture in E36, E21-E25 acupoints has a prokinetic effect on horses. (AU)
