In this study, the effect of ginseng supplementation in the diet of laying hens reared in hot weather was evaluated. A total of 144 laying hens (Hisex Brown) aged 41 weeks were used. The experimental design used was completely randomized in a 2 x 2 factorial arrangement, with the following factors: powdered ginseng supplementation (0 and 125 mg/kg of ginseng) and housing systems (housing in cages and cage-free system). The productive performance and the internal and external quality of the eggs were evaluated, the data were subjected to analysis of variance at 5% probability using the statistical software R (R STUDIO, 2018). Subsequently, the averages of the treatments were compared by the Tukey test, considering the results of (P>0.05). Supplementation with ginseng at a dosage of 125 mg/bird caused relevant variations in the laying rate and in the characteristics of the shell, where birds supplemented with 125 mg/kg of ginseng obtained higher percentage means. The production of eggs by laying hens in the rearing system on the floor at high temperatures and supplemented with ginseng can achieve satisfactory results when compared with the rearing system in conventional cages.
