| Popis: | This study was conducted to evaluate the effects of paprika and marigold extracts on the productivity of Japanese quails, quality and sensorial analysis of eggs. Japanese quails were allocated in a completely randomized design and factorial arrangement 2 × 2 + 1, and four replicates. Diets were formulated based on: 1) corn (control), and 2) sorghum (S) without pigments, 3) S + 0.06% paprika extract (PE), 4) S + 0.01% marigold extract (ME), and 5) S + 0.06% PE and 0.01% ME. There was no effect of the control and factorial interaction on feed intake, egg-laying rate, or egg mass; however, the feed: gain ratio was lower among quail fed with diets containing both extracts. The inclusion of PE and ME in the diets improved the feed: gain ratio and yolk color; the inclusion of PE reduced the feed intake and specific weight of the eggs. Compared to the control, treatments based on sorghum or sorghum + PE led to a difference in egg taste and yolk color in the sensorial analysis. It was concluded that paprika and marigold extracts could be included in quail diets because of improvements in feed: gain ratio and yolk color.Key words: feed additives, poultry feeding, yolk pigmentation |
