A total of 240 one-day-old female yellow-feathered (Hexi dwarf) chickens were randomly divided into two treatment groups, with six replicates per group and 20 chickens per replicate. The control group (CK) received a basal diet, whereas the experimental group was fed a basal diet of +2.00% fermented feed (FJ). The trial lasted for 22 days. Compared with the CK, (1) the growth performance was not affected (p &gt; 0.05); (2) immunoglobin a, immunoglobin g, immunoglobin m, interleukin-1\u03b2, and interleukin-6 were affected (p &lt; 0.05); (3) liver superoxide dismutase, glutathione peroxidase, and catalase were higher (p &lt; 0.05); (4) trypsin activity in the duodenum and cecal Shannon index were increased (p &lt; 0.05); (5) the relative abundance of Actinobacteriota in cecum was increased (p &lt; 0.05); (6) the abundance of dominant microflora of Bacteroides as well as Clostridia UCG-014_norank were increased (p &lt; 0.05). In summary, the fermented feed improved the growth performance, antioxidant activity, immune function, intestinal digestive enzyme activity, morphology, and microflora of yellow-feather chickens.<\/jats:p>","DOI":"10.3390\/ani13223545","type":"journal-article","created":{"date-parts":[[2023,11,16]],"date-time":"2023-11-16T07:11:27Z","timestamp":1700118687000},"page":"3545","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["The Effects of Fermented Feed on the Growth Performance, Antioxidant Activity, Immune Function, Intestinal Digestive Enzyme Activity, Morphology, and Microflora of Yellow-Feather Chickens"],"prefix":"10.3390","volume":"13","author":[{"given":"Fei","family":"Xu","sequence":"first","affiliation":[{"name":"State Key Laboratory for Managing Biotic and Chemical Threats to the Quality and Safety of Agro-Products, Institute of Animal Husbandry and Veterinary Science, Zhejiang Academy of Agricultural Sciences, Hangzhou 310002, China"},{"name":"Junan Agriculture and Rural Bureau, Linyi 276600, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5722-9357","authenticated-orcid":false,"given":"Hongzhi","family":"Wu","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":"Jiajun","family":"Xie","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":"Tao","family":"Zeng","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Managing Biotic and Chemical Threats to the Quality and Safety of Agro-Products, Institute of Animal Husbandry and Veterinary Science, Zhejiang Academy of Agricultural Sciences, Hangzhou 310002, China"},{"name":"Laboratory of Livestock and Poultry Resources (Poultry) Evaluation and Utilization, Ministry of Agriculture and Rural Affairs of China, Hangzhou 310002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijian","family":"Hao","sequence":"additional","affiliation":[{"name":"Junan Agriculture and Rural Bureau, Linyi 276600, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenwu","family":"Xu","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Managing Biotic and Chemical Threats to the Quality and Safety of Agro-Products, Institute of Animal Husbandry and Veterinary Science, Zhejiang Academy of Agricultural Sciences, Hangzhou 310002, China"},{"name":"Laboratory of Livestock and Poultry Resources (Poultry) Evaluation and Utilization, Ministry of Agriculture and Rural Affairs of China, Hangzhou 310002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lizhi","family":"Lu","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Managing Biotic and Chemical Threats to the Quality and Safety of Agro-Products, Institute of Animal Husbandry and Veterinary Science, Zhejiang Academy of Agricultural Sciences, Hangzhou 310002, China"},{"name":"Laboratory of Livestock and Poultry Resources (Poultry) Evaluation and Utilization, Ministry of Agriculture and Rural Affairs of China, Hangzhou 310002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Wickramasuriya, S.S., Park, I., Lee, K., Lee, Y., Kim, W.H., Nam, H., and Lillehoj, H.S.
