We collated data on body mass (BM), as well as small intestine, caecum, colon\/rectum, large and total intestine length in 68 ruminant species, and, while accounting for the phylogenetic structure of the dataset, evaluated both allometric scaling and the potential influence of diet, digestive physiology or climate proxies on measures of intestine length. Intestinal length generally scaled to BM at an exponent higher than the 0.33 expected due to geometry. Diet or digestive physiology proxies did not have an influence on any intestinal length measures, though some proxies indicating more arid natural habitats were positively correlated with measures of the large intestine. The relative size of a forestomach compartment, the omasum, was negatively correlated with intestine length. The results indicate that intestine length measures provide little indication of feeding type or digestive physiology, but rather indicate adaptations to aridity. Higher\u2010than\u2010geometry scaling of intestinal length may be related to the necessity of maintaining geometric (or metabolic) scaling of intestinal surface area while keeping gut diameter, and hence the diffusion distances, small. The way in which space trade\u2010offs determine the macroanatomy of different organs in the abdominal cavity, such as the omasum and the intestine, deserves further investigation.<\/jats:p>","DOI":"10.1002\/jmor.21028","type":"journal-article","created":{"date-parts":[[2019,6,26]],"date-time":"2019-06-26T14:43:36Z","timestamp":1561560216000},"page":"1254-1266","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Gross intestinal morphometry and allometry in ruminants"],"prefix":"10.1002","volume":"280","author":[{"given":"Amanda","family":"McGrosky","sequence":"first","affiliation":[{"name":"Department of Anthropology University of Zurich  Zurich Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daryl","family":"Codron","sequence":"additional","affiliation":[{"name":"Department of Zoology and Entomology University of the Free State  Bloemfontein South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dennis W.
