Surgical removal of the forestomach, the caecum or both the forestomach and the caecum, was performed on growing male golden hamsters (<jats:italic>Mesocricetus auratus<\/jats:italic>) given a low-or high-fibre diet.<\/jats:p><jats:p>2. In Expt J, 18 d after surgery, the hamsters which were given a concentrate before surgery were given an experimental low-fibre diet containing urea or [<jats:sup>15<\/jats:sup>N]urea (10 g\/kg diet) for 9 d. In Expt 2, 5 d after surgery, the hamsters which were given a forage diet before surgery were adapted to an experimental high-fibre diet containing urea (10 g\/kg) and dried Italian ryegrass (<jats:italic>Lolium italicum<\/jats:italic>) powder (400 g\/kg diet) for 5 d, and 10 d after surgery, given a diet containing [<jats:sup>l5<\/jats:sup>N]urea (10 g\/kg diet) for 9 d.<\/jats:p><jats:p>3. In both experiments, removal of the caecum resulted in a significant lowering of both weight-gain and the digestibility of the dry matter, and removal of the forestomach resulted in a significant decrease of both accumulation of<jats:sup>15<\/jats:sup>N in the body protein and proportion of<jats:sup>l5<\/jats:sup>N retained in the body protein as a proportion of the administered dosage.<\/jats:p><jats:p>4. The effect of removal of the caecum on the utilization of [<jats:sup>15<\/jats:sup>N]urea was not apparent in Expt 1, but the utilization of [<jats:sup>15<\/jats:sup>N]urea was significantly lowered by removal of the caecum in Expt 2.<\/jats:p><jats:p>5. These results suggest that the caecum may play a more important role in food utilization than the forestomach. However, the forestomach of the golden hamster plays a significant role in the utilization of dietary urea. It is presumed that the role of the caecum in the utilization of urea may vary under different dietary conditions.<\/jats:p>","DOI":"10.1079\/bjn19810059","type":"journal-article","created":{"date-parts":[[2005,5,18]],"date-time":"2005-05-18T23:51:57Z","timestamp":1116460317000},"page":"503-512","source":"Crossref","is-referenced-by-count":9,"title":["Effects of removal of the forestomach and caecum on the utilization of dietary urea in golden hamsters (<i>Mesocricetus auratus<\/i>) given two different diets"],"prefix":"10.1017","volume":"46","author":[{"given":"Ei","family":"Sakaguchi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junichi","family":"Itoh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hisashi","family":"Shinohara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuro","family":"Matsumoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2007,3,9]]},"reference":[{"key":"S0007114581001359_ref026","volume-title":"Statistical Methods","author":"Snedecor","year":"1967"},{"key":"S0007114581001359_ref019","first-page":"70","volume":"2","author":"Murai","year":"1977","journal-title":"Exp.
