The first AI was conducted at 16 weeks of age in 137 rabbit does that weighted 3.91 \u00b1 0.46 kg. Their body chemical composition was 17.4 \u00b1 0.50%, 16.1 \u00b1 2.6%, 1067 \u00b1 219 kJ\/100 g body weight, for protein, fat and energy, respectively. An increase in body protein, fat and energy content at the first AI did not affect fertility at the first AI but improved it at the second AI (p \u2264 0.030). Moreover, an increase in body fat and energy content at the second AI improved fertility at the second AI (p \u2264 0.001). Fertility at the third AI was positively influenced by body protein at the third AI and the increase in body protein and fat between the second parturition and the third AI (p \u2264 0.030). The percentage of kits born alive at the first and at the second AI improved with the increase in body protein at the first AI (p \u2264 0.040). In conclusion, a minimal body protein and fat content is required at the first AI to optimize the reproductive performance in young does.<\/jats:p>","DOI":"10.3390\/ani11082299","type":"journal-article","created":{"date-parts":[[2021,8,4]],"date-time":"2021-08-04T21:44:24Z","timestamp":1628113464000},"page":"2299","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Relationship between Body Chemical Composition and Reproductive Traits in Rabbit Does"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6180-0181","authenticated-orcid":false,"given":"Meriem","family":"Taghouti","sequence":"first","affiliation":[{"name":"FeedInov CoLab, Integrated Production Systems, Quinta da Fonte Boa, 2005-048 Santar\u00e9m, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2053-9225","authenticated-orcid":false,"given":"Javier","family":"Garc\u00eda","sequence":"additional","affiliation":[{"name":"Departamento de Producci\u00f3n Agraria, Escuela T\u00e9cnica Superior de Ingenier\u00eda Agron\u00f3mica, Agroalimentaria y de Biosistemas, Universidad Polit\u00e9cnica de Madrid, C\/Senda del Rey 18, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5761-5119","authenticated-orcid":false,"given":"Miguel A.","family":"Ib\u00e1\u00f1ez","sequence":"additional","affiliation":[{"name":"Departamento de Econom\u00eda Agraria, Estad\u00edstica y Gesti\u00f3n de Empresas, Escuela T\u00e9cnica Superior de Ingenier\u00eda Agron\u00f3mica, Agroalimentaria y de Biosistemas, Universidad Polit\u00e9cnica de Madrid, C\/Senda del Rey 18, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3727-6874","authenticated-orcid":false,"given":"Ra\u00fal E.","family":"Macchiavelli","sequence":"additional","affiliation":[{"name":"Colegio de Ciencias Agr\u00edcolas, Universidad de Puerto Rico, Mayag\u00fcez 00681-9000, Puerto Rico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2981-8503","authenticated-orcid":false,"given":"Nuria","family":"Nicodemus","sequence":"additional","affiliation":[{"name":"Departamento de Producci\u00f3n Agraria, Escuela T\u00e9cnica Superior de Ingenier\u00eda Agron\u00f3mica, Agroalimentaria y de Biosistemas, Universidad Polit\u00e9cnica de Madrid, C\/Senda del Rey 18, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,4]]},"reference":[{"key":"ref_1","first-page":"29","article-title":"Nutrition of lactating does","volume":"Volume 1","author":"Xiccato","year":"1996","journal-title":"Proceedings of the 6th World Rabbit Congress"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Xiccato, G., and Trocino, A.
