Resumo

The study aimed to evaluate the effect of organic acids and the combination of organic acids and essential oils on performance of replacement pullets hens. 360 animals from Hy-Line Brown lineage with eight weeks of age were distributed in a completely randomized design with four treatments and ten replicates. The experiment lasted 63 days. The treatments (diets) were: Treatment 1 - negative control (no growth promoter); Treatment 2 - positive control (with growth promoter); Treatment 3 – basal ration + organic acids; Treatment 4 – basal ration + organic acids + essential oils. The variables evaluated were the initial and final weights, weight gain, accumulated consumption and feed conversion. There was no significant effect of treatment on any of the investigated parameters. It was concluded that the inclusion of organic acids or a combination of acids and essential oils do not affect the productive performance of replacement pullets.
