Potorous Tridactylus

The gastric distribution of barium sulphate and its subsequent intestinal passage were examined by radiography in Potorous tridactylus. Barium sulphate administered in association with solid food passed to the sacciform forestomach from the tubiform forestomach. However, ingested barium sulphate suspension mainly entered the hindstomach via the gastric sulcus. Barium sulphate which entered the sacciform forestomach remained for no more than 1 h before passing to the hindstomach via the tubiform forestomach. The passage of contrast medium through the intestine was followed in adults administered barium sulphate suspension only. Contrast medium which entered the hindstomach was not detectable there after 10 min. Barium sulphate first arrived at the caecum and proximal colon after 20 min, and by 45 min the majority had reached these organs. It persisted in the caecum and proximal colon for several hours, during which there was some movement into the descending colon and rectum. These results lead towards a new interpretation of the role of the potoroine foregut and hindgut.

Potorous Tridactylus

The structure and function of the gastrointestinal tracts of 2 potoroine marsupials, Aepyprymnus rufescens, the rufous rat-kangaroo, and Potorous tridactylus, the long-nosed potoroo, were examined by the use of radiographic and fluoroscopic techniques. In both species barium sulphate given by mouth entered the sacciform forestomach within 20 min of dosing, but in the same time the hindstomach and duodenum were clearly outlined. Contrast medium reached the hindgut within 1 to 2 h, but was retained there for at least 24 h. A proportion of radio-opaque particles given by mouth also bypassed the sacciform forestomach, but those that entered the gastric region were retained there for up to 93 h. The stomach constituted 50% of total gut capacity, and the hindgut (caecum and colon) 35%. The sacciform forestomach was the largest gastric region. It is concluded that, on the basis of anatomy and digesta movements, the forestomach may be less important, and the hindgut more important, in fermentative digestion in the Potoroinae than in the Macropodidae.

Potorous Tridactylus

Radiographic techniques were used to follow the movement of barium sulfate given orally, either as a suspension or incorporated into feed pellets, through the gastrointestinal tract of two potoroine marsupials, Aepyprymnus rufescens, the rufous rat-kangaroo; and Potorous tridactylus, the long-nosed potoroo. Compared with previously reported results from fed animals, fasting for 12-15 h delayed the passage of contrast medium into the small intestine, but sedation with ketamine hydrochloride visibly increased gastrointestinal tract activity and significantly reduced retention times of contrast medium in the stomach. A daily cycle of ingesta movements within the potoroine stomach, consequent upon the discontinuous feeding pattern and nature of the diet of these small marsupials, is proposed. In this proposal the sacciform region of the forestomach plays a primary role in storage of ingesta for later digestion in the intestine, and fermentative digestion of fibre is of secondary importance.
