MACHADO, CA et al. Performance of Chicks Submitted to Fasting Post-Hatching and with Maltodextrine Supplementing to Diet as Hydrating and Energetic Additive. Rev. Bras. Cienc. Avic. [online]. 2017, vol.19, n.spe, pp.9-14. ISSN 1516-635X.  https://doi.org/10.1590/1806-9061-2015-0140.

This study aimed to evaluate the effect of maltodextrin on performance of chicks passed through four fasting periods. A completely randomized design was performed, consisting of three treatments (1 - control, 2 - 4% saccharose; 3-4% maltodextrin 20) and four fasting periods after hatching (0, 12, 24 and 36 hours) with four replications, totaling 1920 birds of both sexes. The studied variables were: water intake in the first 12 hours, average food intake, average body weight and real feed conversion. Data was submitted to analysis of variance and means were compared with each other by Dunnett test at 5% significance. The use of additives and imposing of different fasting periods did not influence the performance at 42 days old. Therefore, fasted chicks consumed significantly more water. At 7 days old, chicks fasted showed higher body weight and higher feed intake, however, the viability did not suffer any influence, the weight remained higher after 21days with the fast imposition and there was no influence on other variables. There was no effect of fasting on broiler chiken's performance at 42 days old. The inclusion of sucrose and maltodextrin to drinking water stimulated the chick´s water intake and provided higher viability after seven days old.
