The study tested four feeding strategies: Control group (CC) fed exclusively with concentrate feed; group CT supplemented with whole carrot; group OH supplemented with oat hay; and Group CO supplemented with oat hay and whole carrot. Each feeding strategy was tested in 20 rabbits, randomly allocated in five cages with four rabbits each. The average daily weight gain (ADG), feed conversion ratio (FCR), and the amount of concentrated feed consumed daily were estimated in all experimental groups. Group CC displayed the best ADG (37.1 g\/rabbit\/day), carrot had no significant influence on ADG (34.2 g\/rabbit\/day), but oat hay had a negative impact (p &lt; 0.05), either used alone or in combination with carrot (33.0 and 32.6 g\/rabbit\/day, respectively). Supplementation with carrot, oat hay, or both increased the FCR (p &lt; 0.001). Nevertheless, there were no significant differences in final live weight or carcass weight between the rabbits in the different experimental groups. In conclusion, supplementation with oat hay, carrot, or both can be a valid approach to reducing production costs by decreasing concentrate feed without affecting rabbit\u2019s health and meat yield. The combined supplementation with oat hay and carrot proved to be the best option in reducing the amount of concentrate feed ingested by rabbits (less than 1107 g\/animal), but at current market values, supplementation exclusively with oat hay was the less expensive feeding strategy (less 14% than fed exclusively with concentrate feeding).<\/jats:p>","DOI":"10.3390\/ani13193138","type":"journal-article","created":{"date-parts":[[2023,10,9]],"date-time":"2023-10-09T04:48:24Z","timestamp":1696826904000},"page":"3138","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Effect of Diet Supplementation with Oat Hay and Whole Carrot on Rabbit Growth and Productive Efficiency"],"prefix":"10.3390","volume":"13","author":[{"given":"M\u00e1rio","family":"Quaresma","sequence":"first","affiliation":[{"name":"CIISA\u2014Centre for Interdisciplinary Research in Animal Health, Faculty of Veterinary Medicine, University of Lisbon, 1300-477 Lisboa, Portugal"},{"name":"AL4AnimalS\u2014Associate Laboratory for Animal and Veterinary Sciences, Faculty of Veterinary Medicine, University of Lisbon, 1300-477 Lisboa, Portugal"}]},{"given":"Luisa Cristina","family":"Roseiro","sequence":"additional","affiliation":[{"name":"INIAV\u2014Food Technology and Safety Division, National Institute for Agricultural and Veterinary Research (INIAV, IP), Quinta do Marqu\u00eas, 2780-159 Oeiras, Portugal"},{"name":"GeoBioTec\u2014Geobiosciences, Geoengineering e Geobiotechnologies, NOVA School of Science and Technology, Campus de Caparica, 2829-516 Caparica, Portugal"}]},{"given":"Tatiana","family":"Ferreira","sequence":"additional","affiliation":[{"name":"CIISA\u2014Centre for Interdisciplinary Research in Animal Health, Faculty of Veterinary Medicine, University of Lisbon, 1300-477 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4393-2150","authenticated-orcid":false,"given":"Maria Leonor","family":"Nunes","sequence":"additional","affiliation":[{"name":"CIIMAR\u2014Interdisciplinary Centre of Marine and Environmental Research, University of Porto, Terminal de Cruzeiros do Porto de Leix\u00f5es, Av.
