The experiment attempted to investigate whether dietary polyphenols (Polygain (POL)) could ameliorate the aforementioned adverse effects of HS on performance and meat quality. One hundred and twenty one day-old-male chicks were allocated to two temperature conditions, thermoneutral (TN) or HS, and fed with either a control diet (CON) or the CON plus four different doses of POL (2, 4, 6 and 10 g\/kg). Heat stress caused respiratory alkalosis as evidenced by increased rectal temperature (p &lt; 0.001) and respiration rate (p &lt; 0.001) due to increased blood pH (p &lt; 0.001). Heat stress decreased final body weight (p = 0.061) and breast muscle water content (p = 0.013) while POL improved both (p = 0.002 and p = 0.003, respectively). Heat stress amplified muscle damages, indicated by increased thiobarbituric acid reactive substances (p &lt; 0.001) and reduced myofibril fragmentation index (p = 0.006) whereas POL improved both (p = 0.037 and p = 0.092, respectively). Heat stress impaired meat tenderness (p &lt; 0.001) while POL improved it (p = 0.003). In conclusion, HS impaired growth performance and meat quality whereas POL ameliorated these responses in a dose-dependent manner, and effects of POL were evident under both temperature conditions.<\/jats:p>","DOI":"10.3390\/ani10071158","type":"journal-article","created":{"date-parts":[[2020,7,10]],"date-time":"2020-07-10T09:25:28Z","timestamp":1594373128000},"page":"1158","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["A Dietary Sugarcane-Derived Polyphenol Mix Reduces the Negative Effects of Cyclic Heat Exposure on Growth Performance, Blood Gas Status, and Meat Quality in Broiler Chickens"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1857-2133","authenticated-orcid":false,"given":"Majid","family":"Shakeri","sequence":"first","affiliation":[{"name":"Department of Medicine, The University of Washington, Seattle WA 98102, USA"},{"name":"Faculty of Veterinary and Agricultural Sciences, The University of Melbourne, Parkville Melbourne, Victoria 3010, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1899-2090","authenticated-orcid":false,"given":"Jeremy J.","family":"Cottrell","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary and Agricultural Sciences, The University of Melbourne, Parkville Melbourne, Victoria 3010, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stuart","family":"Wilkinson","sequence":"additional","affiliation":[{"name":"Feedworks Pty Ltd., Romsey, Victoria 3434, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8649-6892","authenticated-orcid":false,"given":"Hieu H.","family":"Le","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary and Agricultural Sciences, The University of Melbourne, Parkville Melbourne, Victoria 3010, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2450-0830","authenticated-orcid":false,"given":"Hafiz A.
