They were kept in family groups of 2-10. Litter size varied from 1-4; singletons (2%), twins (35%), triplets (55%), and quadruplets (8%). The mean annual increase of weaned young was 3\u00b724 per pair. <\/jats:p><jats:p> The median interbirth interval was 154 days. Of 46 pairs of marmosets, 8 failed to produce young. <\/jats:p><jats:p> Approximately 11% of young born were stillborn and a further 32% of all young born died within 3 weeks; perinatal mortality is largely a result of the failure of parents to rear more than 2 young. In only 2 of 68 triplet births did the parents rear the young unaided. <\/jats:p><jats:p> 53% of young born were males but differential mortality reduced the final sex ratio for live young to 50\u00b75% males. Females did not accept and rear the young after caesarian sections. <\/jats:p><jats:p> The linear regression of the growth curve from 5-17 months (where y = weight in grams and x = months) could be expressed as y = 16\u00b76 x + 163\u00b76. <\/jats:p><jats:p> The data from 4 marmoset colonies are compared and the relative efficiency of breeding methods discussed. <\/jats:p>","DOI":"10.1258\/002367782780908760","type":"journal-article","created":{"date-parts":[[2007,6,10]],"date-time":"2007-06-10T23:36:30Z","timestamp":1181518590000},"page":"88-97","source":"Crossref","is-referenced-by-count":55,"title":["Reproduction, infant survival and productivity of a colony of common marmosets (<i>Callithrix jacchus jacchus<\/i>)"],"prefix":"10.1177","volume":"16","author":[{"given":"Trevor B.","family":"Poole","sequence":"first","affiliation":[{"name":"Department of Zoology, University College of Wales, Penglais, Aberystwyth, Dyfed, SY23 3DA, United Kingdom; Department of Zoology, National University of Singapore, Kent Ridge, Singapore 0511"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rosemary G.","family":"Evans","sequence":"additional","affiliation":[{"name":"Department of Zoology, University College of Wales, Penglais, Aberystwyth, Dyfed, SY23 3DA, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1982,1,1]]},"container-title":["Laboratory Animals"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1258\/002367782780908760","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1258\/002367782780908760","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,4]],"date-time":"2025-03-04T16:33:09Z","timestamp":1741105989000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1258\/002367782780908760"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1982,1,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1982,1,1]]}},"alternative-id":["10.1258\/002367782780908760"],"URL":"https:\/\/doi.org\/10.1258\/002367782780908760","relation":{},"ISSN":["0023-6772","1758-1117"],"issn-type":[{"value":"0023-6772","type":"print"},{"value":"1758-1117","type":"electronic"}],"subject":[],"published":{"date-parts":[[1982,1,1]]}}}
