SIGLER GALVAN, Sergio et al. Effect of alpha-lipoic acid on productive parameters and carcass quality in broiler chickens. Rev. mex. de cienc. pecuarias [online]. 2015, vol.6, n.2, pp.207-219. ISSN 2448-6698.

Broilers production has been employed various additives, including antioxidants that have played an important role in it. Within these products, alpha lipoic acid (ALA) has distinguished; its addition in the diet provides different benefits to the animals. Therefore, the objective of this study was to evaluate the productive performance and meat quality of broilers with use of ALA in different doses (0, 40, 80, 160 and 320 ppm). The experiment was divided into two phases, the first productive performance was evaluated using 1,000 birds that were divided into five treatments with 200 animals each; the duration of this test was 49 d. In the second phase the sacrifice of animals was performed, 20 samples were obtained by treatment and testing the meat quality of them. The results of the production and quality meat variables were analyzed in a completely randomized design. No significant differences (P>0.05) were found by the addition of ALA on productive variables; however, chicks receiving 40 ppm of ALA lost less water by cooking.
