| The objective of this study was to evaluate productive performance and egg quality of Japanese quails (Cortunix japonica) fed with synthetic and natural pigments. The treatments used were: 0.8% paprika extract (Capsicum annuum), 0.8% marigold flower extract, 4% paprika extract and 4% marigold flower extract and 0.045% synthetic pigment (Canthaxanthin) in feed. A total of 240 Japanese quails at 20 weeks of age were distributed in a completely randomized experimental design with five treatments and six replicates, with eight quails per experimental unit (30 experimental units). There was no difference (p > 0.05) for the evaluated parameters, except for yolk color which showed significant difference (p < 0.05) between the treatments used. The... |

| The objective was to evaluate the performance, egg quality, thermoregulation, body morphology and behavior of different categories of laying poultry. Two treatments with two genetic groups were used, 50 birds of the Hisex Brown strain and 50 birds of the Black Avifran chicken breed with 55 weeks, distributed in a completely randomized design with 10 replicates and 5 birds in each experimental unit. The variables egg weight, weight and percentage of albumen, yolk and shell, marketable eggs, specific gravity, color b *, egg / poultry production day-1 were not different (p > 0.05) between the two groups. Feed conversion by egg mass and dozen eggs, yolk color, L color, diameter, height, shell color presented a difference (p < 0.05), being higher values... |
