| 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... |

| ABSTRACT Corn is the major energy ingredient in diets, and many ingredients have been tested aiming to replace it. In this regard, sorghum stands out for its chemical profile similar to that of corn. However, because it is low in carotenoids, its inclusion in diets reduces the egg yolk color pigmentation, which can be corrected by the addition of synthetic pigments. This study aimed to evaluate the performance and egg quality of Japanese quail (Coturnix japonica) supplemented with red (canthaxanthin) and yellow (apo-ester 10%) synthetic pigments. A total of 150 quail at 70 days of age were distributed according to the experimental diet [R1: corn-based control diet (DC); R2: sorghum-based diet (DS); R3: DS + yellow; R4: DS + yellow + red; and R5: DS + red]... |
