The rate of flow of fluid from the caecum and from the large colon was measured in four Shetland-type ponies fed a hay diet. In two ponies with cannulas in the caecum and at the origin of the right ventral colon, a continuous intracaecal infusion of a solution of chromium EDTA was used and samples were obtained from the cannula at the origin of the right ventral colon. Based on four determinations, the liquid flow from the caecum was 54.2 +/- 1.89 litres d-1. In the other two ponies with cannulas in the origin of the right ventral colon and near the end of the right dorsal colon, a continuous infusion of chromium EDTA was made into the right ventral colon and samples were obtained from the right dorsal colon. The flow rate towards the end of the dorsal colon was 49.4 +/- 1.25 litres d-1, based on four determinations. The capacities of the caecum and large colon after death were 7.0 +/- 0.8 and 17.7 +/- 3.7 litres, respectively.
对四匹以干草为食的设得兰型矮种马，测量了来自盲肠和大结肠的液体流速。在两匹在盲肠和右腹侧结肠起始处置有插管的矮种马中，持续向盲肠内输注铬乙二胺四乙酸溶液，并从右腹侧结肠起始处的插管获取样本。基于四次测定，来自盲肠的液体流量为54.2±1.89升/天。在另外两匹在右腹侧结肠起始处和右背侧结肠末端附近置有插管的矮种马中，持续向右腹侧结肠内输注铬乙二胺四乙酸，并从右背侧结肠获取样本。基于四次测定，朝向背侧结肠末端的流速为49.4±1.25升/天。死后盲肠和大结肠的容量分别为7.0±0.8升和17.7±3.7升。
