Ten gastrointestinal contrast studies were performed with barium on seven clinically healthy ostriches. Concentrations of 25-100% w/vol liquid barium sulfate at 7 and 10 ml/kg were administered by stomach tube after withholding food for 16 h. A 6-frame technique for left-to-right lateral views in standing and a 3-frame technique for the dorsoventral views in sternally recumbent adult ostriches were used for survey and contrast radiographs. Objectives were to describe the appearance of the normal gastrointestinal tract with contrast radiography and to provide a guideline for optimal dosage and concentration of barium sulfate as well as a reliable protocol for frequency of radiographs. Structures that were consistently identified included the esophagus, proventriculus, ventriculus, duodenum, jejunum, proximal, and distal rectum. Due to the superimposition of the remainder of the small intestine, individual components were difficult to differentiate. The caeca were inconsistently highlighted and only for a short time. The ventral pouch of the coprodeum never filled with contrast medium.
对7只临床健康的鸵鸟进行了10次胃肠道钡剂造影检查。禁食16小时后，通过胃管给予浓度为25 - 100%（重量/体积）的液体硫酸钡，剂量为7和10毫升/千克。采用6帧技术拍摄成年鸵鸟站立时从左到右的侧位片，以及3帧技术拍摄成年鸵鸟胸骨卧位时的背腹位片，用于进行普查和对比造影X线片拍摄。目的是描述正常胃肠道造影X线表现，提供硫酸钡最佳剂量和浓度指南以及可靠的X线片拍摄频率方案。始终能识别出的结构包括食管、腺胃、肌胃、十二指肠、空肠、直肠近端和远端。由于小肠其余部分相互重叠，难以区分各个组成部分。盲肠显影不一致，且仅在短时间内显影。粪道腹侧囊从未充满造影剂。
