In our experimental condition, 180 chicks were randomly distributed into four environmentally controlled rooms (three replicates\/treatment). The experimental design consisted of four light sources: neon (Control), Neutral (Neutral LED; K = 3500\u20133700), Cool (Cool LED; K = 5500\u20136000), and Warm (Warm LED; K = 3000\u20132500). Upon reaching the commercial weight (3.30 \u00b1 0.20 kg live weight), 30 birds from each group were randomly selected, and live and carcass weight were evaluated to determinate the carcass yield. Following the slaughtering, samples of hemibreast meat were collected from each group and analyzed for physical and chemical properties, fatty acids composition, and volatile compounds. Live weight and carcass weight were negatively influenced by the Warm LED; however, no significant differences were observed in carcass yield in any of the experimental conditions. Higher drip loss values were detected in breast meat samples obtained by broilers reared under Neutral and Cool LEDs. In regard to the meat fatty acids profiles, higher polyunsaturated fatty acids (PUFA) values were detected with the Warm LED; however, the ratio of PUFA\/saturated fatty acids (SFA) did not change in any group. The evaluation of volatile profiles in cooked chicken meat led to the identification of 18 compounds belonging to the family of aldehydes, alcohols, ketones, and phenolic compounds, both at 0 (T0) and 7 (T7) d after the cooking. The results of the present study suggest that the LED represents an alternative technology that is cheaper and more sustainable than traditional light sources, since it allows economic savings for poultry farming without significant alterations on the production parameters or the quality of the product.<\/jats:p>","DOI":"10.3390\/ani11061505","type":"journal-article","created":{"date-parts":[[2021,5,23]],"date-time":"2021-05-23T23:58:05Z","timestamp":1621814285000},"page":"1505","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Evaluation of Chemical Composition and Meat Quality of Breast Muscle in Broilers Reared under Light-Emitting Diode"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9030-4881","authenticated-orcid":false,"given":"Francesca","family":"Bennato","sequence":"first","affiliation":[{"name":"Faculty of Bioscience and Technology for Food, Agriculture and Environment, University of Teramo, 64100 Teramo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3102-6804","authenticated-orcid":false,"given":"Andrea","family":"Ianni","sequence":"additional","affiliation":[{"name":"Faculty of Bioscience and Technology for Food, Agriculture and Environment, University of Teramo, 64100 Teramo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5927-6680","authenticated-orcid":false,"given":"Camillo","family":"Martino","sequence":"additional","affiliation":[{"name":"Istituto Zooprofilattico Sperimentale dell\u2019Abruzzo e del Molise G.
