肠麻痹或嵌塞性梗阻显著延缓了动物体内的肠梗阻的通过速率，并可导致严重的临床问题。在许多圈养动物中，食物通过的大致速率是众所周知的，因此如果发生肠阻塞，可以快速诊断和治疗。虽然鳍足类动物通常被圈养，但这些动物中的寄生虫的传播速度尚不清楚。在这项研究中，经过的时间段之前，最初的排便的染料标记的膳食确定为20鳍足类代表三个物种。该初始排便时间（IDT）可作为粪便排出速率的良好指标。测定的鳍足类平均IDT非常快，平均为5小时或更短。没有其他中大型食肉动物或杂食动物显示出如此快的通过速度。 考虑到这些动物的肠道与身体长度之比是人类中最大的，这些动物的排泄速度非常快。
Torpid bowels or an impaction obstruction significantly retards the rate of passage of digesta in an animal and can lead to serious clinical problems. In many captive animals the approximate rate of food passage is well-known, thus allowing for rapid diagnosis and treatment if an intestinal blockage occurs. Although pinnipeds are commonly kept in captivity, the rate of passage of digesta in these animals is not known. In this study, the time period that elapsed before the initial defecation of a dye-marked meal was determined for 20 pinnipeds representing three species. This initial defecation time (IDT) serves as a good indicator of the rate of passage of digesta. The mean IDTs determined for pinnipeds were very fast averaging 5 h or less. No other medium to large carnivore or omnivore has been shown to exhibit such a rapid rate of passage. The extraordinarily fast excretion rate of these animals is even more remarkable considering that their intestine to body length ratios are among the largest in the a...
