Pigmentantes vegetais e sintéticos em dietas de galinhas poedeiras Negras

The objective of this work was to evaluate the performance and quality of eggs of laying hens fed Avifran Black with the inclusion of 0.8% of plant extracts pigmentation solutions (extract of paprika (Capsicum annuum), flower marigold (Tagetes erectus) and 0.045% of synthetic pigmentante (canthaxanthin) in the feed. We used 120 layers Avifran distributed in Black 4 treatments, 6 reps with 5 birds each, totaling 24 experimental plots. Zootechnical performance analyses were undertaken, quality of the eggs and egg yolk color via color range and color matching methods using digital calorimeter. The inclusion of 0.8% of natural pigmentation solutions in the diet of laying hens Avifran created under warm, Black, can be used as a way to replace the canthaxanthin (synthetic pigment), as it provides the egg yolk coloring, encouraging the marketing of eggs, and does not affect the performance and the internal and external quality of eggs (P > 0.05).
