The parameter for analysing the results was defined as \u0394\u00a0=\u00a0dietary calcium\/phosphorus (Ca\/P) ratio \u2013 faecal Ca\/P ratio. In previous studies, hindgut fermenters had significantly higher \u0394 values than ruminants (sheep, cattle, goats), which was explained by the high calcium digestibilities in hindgut fermenters in contrast to highly efficient phosphorus recycling in ruminants. The first hypothesis of the present study was that different types of ruminants (grazer, browser, intermediate feeder) would show differences in \u0394 as a proxy for quantitative calcium and phosphorus metabolism. The second hypothesis was that camelids as functional, but not taxonomic ruminants would show \u0394 values similar to ruminants. We used herbivorous zoo animals (17 species, hindgut and foregut fermenters), which were kept on their regular diet without variation for 1 week. Then, faecal samples were obtained from the individual animals. Feed items and faecal samples were analysed for calcium and phosphorus, and dietary and faecal Ca\/P ratios as well as \u0394 were calculated. A comparison of the species groups (one\u2010way ANOVA on ranks, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.05) showed that zoo hindgut fermenters had significantly higher \u0394 values (0.67 \u00b1 0.34) than camelids and zoo ruminants (\u20131.07 \u00b1 0.35 and \u20131.87 \u00b1 1.56). There was no significant difference between camelids, grazers (\u20131.49 \u00b1 1.31), browsers (\u20131.63 \u00b1 0.88) and intermediate feeders (\u20132.11 \u00b1 1.76). The ruminant species from this study had markedly lower \u0394 than domestic ruminants from literature data. Especially intermediate feeders had low \u0394, possibly due to more efficient phosphorus recycling than the domestic ruminants.<\/jats:p>","DOI":"10.1002\/vms3.667","type":"journal-article","created":{"date-parts":[[2021,11,23]],"date-time":"2021-11-23T04:46:50Z","timestamp":1637642810000},"page":"349-356","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A pilot study on dietary and faecal calcium\/phosphorus ratios in different types of captive ruminating herbivores"],"prefix":"10.1002","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5363-335X","authenticated-orcid":false,"given":"Linda","family":"B\u00f6swald","sequence":"first","affiliation":[{"name":"Chair for Animal Nutrition and Dietetics Faculty of Veterinary Medicine, Department of Veterinary Sciences Ludwig\u2010Maximilians\u2010Universit\u00e4t M\u00fcnchen  Munich Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Britta","family":"Dobenecker","sequence":"additional","affiliation":[{"name":"Chair for Animal Nutrition and Dietetics Faculty of Veterinary Medicine, Department of Veterinary Sciences Ludwig\u2010Maximilians\u2010Universit\u00e4t M\u00fcnchen  Munich Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maike","family":"L\u00fccht","sequence":"additional","affiliation":[{"name":"M\u00fcnchener Tierpark Hellabrunn AG  Munich Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christine","family":"Gohl","sequence":"additional","affiliation":[{"name":"M\u00fcnchener Tierpark Hellabrunn AG  Munich Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ellen","family":"Kienzle","sequence":"additional","affiliation":[{"name":"Chair for Animal Nutrition and Dietetics Faculty of Veterinary Medicine, Department of Veterinary Sciences Ludwig\u2010Maximilians\u2010Universit\u00e4t M\u00fcnchen  Munich Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,11,22]]},"reference":[{"doi-asserted-by":"publisher","key":"e_1_2_9_2_1","DOI":"10.1007\/978-1-4020-6860-7"},{"doi-asserted-by":"publisher","key":"e_1_2_9_3_1","DOI":"10.1007\/BF01014834"},{"doi-asserted-by":"publisher","key":"e_1_2_9_4_1","DOI":"10.4102\/jsava.v83i1.508"},{"volume-title":"Dietary and faecal Ca\/P ratios in mammals","year":"2017","author":"B\u00f6swald L.","key":"e_1_2_9_5_1"},{"doi-asserted-by":"publisher","key":"e_1_2_9_6_1","DOI":"10.1111\/jpn.12844"},{"volume-title":"Investigations on dietary and faecal Ca\/P ratios in hindgut and foregut fermenters","year":"2019","author":"B\u00f6swald L.","key":"e_1_2_9_7_1"},{"doi-asserted-by":"publisher","key":"e_1_2_9_8_1","DOI":"10.1079\/NRR19910011"},{"doi-asserted-by":"publisher","key":"e_1_2_9_9_1","DOI":"10.2527\/jas1973.372450x"},{"volume-title":"Getting it out of the (digestive) system: Hindgut fermenters and calcium","year":"2008","author":"Clauss M.","key":"e_1_2_9_10_1"},{"doi-asserted-by":"publisher","key":"e_1_2_9_11_1","DOI":"10.1007\/978-3-540-72422-3_3"},{"doi-asserted-by":"publisher","key":"e_1_2_9_12_1","DOI":"10.1007\/s00360-015-0904-x"},{"doi-asserted-by":"publisher","key":"e_1_2_9_13_1","DOI":"10.1007\/s003600050144"},{"doi-asserted-by":"publisher","key":"e_1_2_9_14_1","DOI":"10.1007\/BF00452421"},{"doi-asserted-by":"publisher","key":"e_1_2_9_15_1","DOI":"10.1079\/BJN19480065"},{"doi-asserted-by":"publisher","key":"e_1_2_9_16_1","DOI":"10.1007\/BF00378733"},{"doi-asserted-by":"publisher","key":"e_1_2_9_17_1","DOI":"10.1515\/mamm.1972.36.2.226"},{"doi-asserted-by":"publisher","key":"e_1_2_9_18_1","DOI":"10.1002\/jmor.10580"},{"doi-asserted-by":"publisher","key":"e_1_2_9_19_1","DOI":"10.3168\/jds.S0022-0302(94)77140-X"},{"doi-asserted-by":"publisher","key":"e_1_2_9_20_1","DOI":"10.3177\/jnsv.66.60"},{"volume-title":"Supplemente zur Tierern\u00e4hrung f\u00fcr Studium und Praxis","year":"2014","author":"Kamphues J.","key":"e_1_2_9_21_1"},{"doi-asserted-by":"publisher","key":"e_1_2_9_22_1","DOI":"10.1111\/j.1469-7998.1987.tb01544.x"},{"issue":"13","key":"e_1_2_9_23_1","first-page":"19","article-title":"Particularities in forestomach anatomy, physiology and biochemistry of camelids compared to ruminants","author":"Lechner\u2010Doll M.","year":"1995","journal-title":"Elevage et Alimentation du Dromadaire\u2014Camel Production and Nutrition Options M\u00e9diterran\u00e9ennes, Serie B.
