A total of 600 one-day-old Arbor Acres male broilers with similar body weights were randomly divided into three groups (10 replicates\/group, 20 broilers\/replicate). Birds in the three experimental groups were fed a basal diet with CA at 0, 300, and 500 mg\/kg. The results showed that supplementing with 300 mg\/kg CA significantly increased (p &lt; 0.05) 42 d BW and 22\u201342 d ADG, and markedly decreased (p &lt; 0.05) 22\u201342 d F: G ratio in comparison to the control group. Birds fed a diet with 300 mg\/kg CA had a higher (p &lt; 0.05) pH of chicken meat at 24 h and 48 h post mortem and lower (p &lt; 0.05) yellowness values (b*) of chicken meat at 45 min and 24 h post mortem, along with a lower (p &lt; 0.05) cooking loss. Supplementing with 300 mg\/kg CA significantly increased (p &lt; 0.05) serum and liver T-SOD activity, serum T-AOC level, as well as jejunual GST activity, and significantly decreased (p &lt; 0.05) liver MDA content when compared with the control group. These results indicate that diet supplementation with 300 mg\/kg CA containing TBHQ and TP could improve growth performance and meat quality by increasing the antioxidant capacity of broilers.<\/jats:p>","DOI":"10.3390\/ani14030360","type":"journal-article","created":{"date-parts":[[2024,1,23]],"date-time":"2024-01-23T07:22:32Z","timestamp":1705994552000},"page":"360","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Effects of Complex Antioxidants Added to Chicken Diet on Growth Performance, Serum Biochemical Indices, Meat Quality, and Antioxidant Capacity"],"prefix":"10.3390","volume":"14","author":[{"given":"Xiaochun","family":"Chen","sequence":"first","affiliation":[{"name":"Institute of Animal Science, Chengdu Agricultural College, Chengdu 611130, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Zeng","sequence":"additional","affiliation":[{"name":"Key Laboratory for Animal Disease-Resistance Nutrition of Ministry of Education, Institute of Animal Nutrition, Ministry of Agriculture and Rural Affairs, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangyi","family":"Zeng","sequence":"additional","affiliation":[{"name":"Key Laboratory for Animal Disease-Resistance Nutrition of Ministry of Education, Institute of Animal Nutrition, Ministry of Agriculture and Rural Affairs, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiufeng","family":"Zeng","sequence":"additional","affiliation":[{"name":"Key Laboratory for Animal Disease-Resistance Nutrition of Ministry of Education, Institute of Animal Nutrition, Ministry of Agriculture and Rural Affairs, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,23]]},"reference":[{"key":"ref_1","first-page":"20","article-title":"Breeding for efficiency in the broiler chicken: A review","volume":"4","author":"Tallentire","year":"2016","journal-title":"Agron.
