We randomly divided five hundred and seventy-six one-day-old male broilers into four groups each with six replicates and 24 chickens in each replicate. The control group (CG) was fed the basal diet, and the other groups were given powder lycopene of 10, 20, and 30 mg\/kg lycopene (LP10, LP20, and LP30, respectively). Compared with the control group, (1) the dietary lycopene increased (p = 0.001) the average daily gain and decreased (p = 0.033) the feed conversion ratio in the experimental groups; (2) the glutathione peroxidase enzyme contents in LP20 were higher (p =&lt; 0.001) in myocardium; (3) the crude protein contents were higher (p = 0.007) in the group treated with 30 mg\/kg dietary lycopene; (4) the jejunum villous height was higher (p = 0.040) in LP20; (5) the Unclassified-f-Ruminococcaceae relative abundance was significantly higher (p = 0.043) in LP20. In this study, adding 20 mg\/kg dietary lycopene to the broiler chickens\u2019 diets improved the growth performance, antioxidant capacity, meat quality, intestine histomorphology, and cecal microbiota in broiler chickens.<\/jats:p>","DOI":"10.3390\/ani14020203","type":"journal-article","created":{"date-parts":[[2024,1,8]],"date-time":"2024-01-08T05:21:38Z","timestamp":1704691298000},"page":"203","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Effects of Dietary Lycopene on the Growth Performance, Antioxidant Capacity, Meat Quality, Intestine Histomorphology, and Cecal Microbiota in Broiler Chickens"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5722-9357","authenticated-orcid":false,"given":"Hongzhi","family":"Wu","sequence":"first","affiliation":[{"name":"Tropical Crop Genetic Resource Research Institute, Chinese Academy of Tropical Agricultural Sciences, Haikou 571101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sibo","family":"Wang","sequence":"additional","affiliation":[{"name":"Abna Management (Shangai) Co., Ltd., Shanghai 200050, China"},{"name":"College of Animal Science and Technology, Northeast Agricultural University, Harbin 150030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiajun","family":"Xie","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Northeast Agricultural University, Harbin 150030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fengjie","family":"Ji","sequence":"additional","affiliation":[{"name":"Tropical Crop Genetic Resource Research Institute, Chinese Academy of Tropical Agricultural Sciences, Haikou 571101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiqi","family":"Peng","sequence":"additional","affiliation":[{"name":"Tropical Crop Genetic Resource Research Institute, Chinese Academy of Tropical Agricultural Sciences, Haikou 571101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinyu","family":"Qian","sequence":"additional","affiliation":[{"name":"Tropical Crop Genetic Resource Research Institute, Chinese Academy of Tropical Agricultural Sciences, Haikou 571101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"Shen","sequence":"additional","affiliation":[{"name":"Hainan Xuhuai Technology Co., Ltd., Haikou 571127, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guanyu","family":"Hou","sequence":"additional","affiliation":[{"name":"Tropical Crop Genetic Resource Research Institute, Chinese Academy of Tropical Agricultural Sciences, Haikou 571101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"101174","DOI":"10.1016\/j.psj.2021.101174","article-title":"Prebiotics and alternative poultry production","volume":"100","author":"Ricke","year":"2021","journal-title":"Poult.
