The effect of resection of 75% (length measurement) of the large colon in ponies was studied. Ten ponies in good physical condition were divided into two groups: group I consisted of the six experimental ponies and group II of four control ponies. Preoperatively and postoperatively for five months, ten clinicopathological parameters were determined: body weight, venous blood pH, plasma bicarbonate, total plasma protein concentration, serum electrolyte values (sodium, potassium, chloride), and fecal osmolarity. Subjective assessment of attitude and appetite revealed no difference between the groups or within groups at any time. Resection of a major portion of the large colon did not significantly influence the clinicopathological parameters evaluated. The hematocrit of the ponies in group I did decrease during the first postoperative month and this was attributed to whole blood loss associated with the resection procedures. The results of this investigation indicated that resection of 75% of the large colon in ponies is compatible with life.
研究了切除小马75%（长度测量）的大结肠的效果。将10匹身体状况良好的小马分为两组：第一组由6匹实验小马组成，第二组由4匹对照小马组成。在术前和术后五个月，测定了10项临床病理参数：体重、静脉血pH值、血浆碳酸氢盐、总血浆蛋白浓度、血清电解质值（钠、钾、氯）和粪便渗透压。对态度和食欲的主观评估显示，两组之间或组内任何时候均无差异。切除大部分大结肠对所评估的临床病理参数没有显著影响。第一组小马的血细胞比容在术后第一个月确实有所下降，这归因于与切除手术相关的全血流失。这项研究的结果表明，切除小马75%的大结肠与生命相容。
