Regional differences in hindgut structure and function in the nutria, Myocastor coypus

Abstract: Morphologically the large intestine of the nutria resembles that of other caviomorphs, notably the guinea pig. The cecum is voluminous: it contributes 8.6% of the total intestinal length and 12.7% of the total intestinal surface area (considering the surface enlargement factor). It contains 27-32% of the wet ingesta and 20-23% of the dry matter in the gastrointestinal tract. In the colon the corresponding figures are: 21.8% of length, 12.6% of surface area, 16-21% of wet ingesta, and 16-40% of dry matter. The … Show more

“…We recognize the transverse colon in the capybara, but Snipes et al (1988) did not mention the transverse colon in their study about the nutria and Alogninouwa et al (1996) did not mention the transverse colon in the grasscutter.…”

“…The cecum of rodents has been divided into ampulla ceci (Basis ceci), corpus ceci and apex ceci (Snipes, 1979a;1979b;Perrin and Curtis, 1980;Snipes, 1981;1982a;1982b;Snipes et al, 1988;1990). In the capybara, we recognized the same parts.…”

“…In a comprehensive compara-tive rodent gastrointestinal anatomical study, Gorgas (1967) observes two longitudinally arranged folds in the proximal colon forming a groove in various caviomorph and hystricomorphic rodents. A colonic mucosal furrow or groove was also later described in the nutria (Snipes et al, 1988;Takahashi and Sakaguchi, 2000), chinchilla and guinea pig (Holtenius and Björnhag, 1985), and the Patagonian mara (Gorgas, 1967;Weissengruber, 2000). Within the wall of the groove of the latter species, Gorgas (1967) reports prominent venous sinusoids which he postulates, upon filling, may compartmentalize the colonic lumen.…”

“…This mechanism is particularly used in small herbivorous mammals and has been studied extensively in the rabbit (Björnhag, 1981), marsupials (Björnhag, 1994;Hume and Moyle, 1995), and certain myomorph rodents such as the Scandinavian lemming and rat (Sperber et al, 1983), the guinea-pig and chinchilla (Holtenius and Björn-hag, 1985), as well as nutrias (Snipes et al, 1988).…”
