Resumen

The aim of this study was to evaluate the effect of dietary supplementation with ethanolic extract of mango residues (EERM) in two genotypes of hens on egg production, egg quality, nutritional composition, and yolk fatty acid profile. For 12 weeks, 200 30- week-old laying hens were randomly assigned to 10 treatments arranged in a 2×5 factorial design (2 genotypes, Creole and Novogen Brown, and 5 levels of EERM [0, 500, 1000, 1500, and 2000 ppm]). EERM at 2000 ppm maximized yield, albumen height, Haugh unit, and yolk yellowness. Eggs from the Criolla hen presented higher proportions of fat and ash. EERM did not cause changes in egg moisture, protein, fat, ash, or carbohydrates. The fatty acid profile in the egg yolk of free-range hens showed higher amounts of docosahexaenoic acid (DHA) and total ω-3, with an improved ω-6/ω-3 ratio. The MMRE at doses of 1500 and 2000 ppm resulted in an improved ω-6/ω-3 ratio. In conclusion, MMRE in the diet of hens could stimulate the production of functional eggs for human consumption. © (2026), (Universidad Nacional Mayor de San Marcos). All rights reserved.
