Resumo: | ABSTRACT Post-hatch delayed placement damages, physical and physiological development of broiler chicks. The objective of this study was to ascertain adequate levels of glutamine inclusion in post-hatch and pre-starter feed, in order to minimize the negative effects of post-hatch delayed placement on broiler chicks. The birds were distributed in a completely randomized design, with four treatments and five replicates of ten birds each. Four levels of glutamine supplementation (0, 1, 2 and 3%) were used in the pre-starter feed, which was given to the chicks in the transportation box and during the pre-starter phase. After 24 hours of access to this feed, and at 7 days of age, the chicks’ performance, yolk sac retraction, plasma glucose concentration, weight and small-intestine histomorphometry were evaluated. From seven to ten days of age, a metabolizability assay was performed. Glutamine supplementation tended to increase the use of the yolk sac, the concentration of plasma glucose (p&lt;0.10) and the depth of the crypt in the ileum after 24 hours of life (p&lt;0.05). There was no statistical difference between the glutamine supplementation levels, in relation to glucose, histomorphometry or metabolizability in the pre-starter phase. Glutamine concentrations did not differ in relation to performance, histomorphometry of the small intestine or metabolizability of nutrients in the pre-starter phase.
