Comparison in the quality of eggs obtained in an outdoor pen production system and those produced in a cage system
Mexico is the main consumer of eggs worldwide with more than 23.22 kg of egg per capita per year. In recent years, production systems have diversified with the introduction of systems that promote animal welfare. The present study was carried out with the aim of comparing the quality of eggs produced in an outdoor pen system against those of a semi-technified cage system. The internal and external physical characteristics of the eggs were evaluated at 3 and 15 d after laying. The results of the present study showed that the egg produced in an outdoor pen system has less cleanliness (P<0.001), and lower quality (P<0.005) than eggs produced in the cage system, according to the classification of the Mexican Standard of “Poultry Products -fresh chicken egg- specifications and test methods” (NMX-FF-127-SCFI-2016). Finally, the storage time significantly decreased the quality of the egg produced in the outdoor pen system (P<0.001), but not that of the eggs from the conventional cage system. In conclusion, under the conditions of the present work, the quality of the egg from conventional systems is better than that of the egg produced in outdoor pen systems, especially after 15 d of storage. These results suggest that more studies are needed to evaluate the effects of management practices, preventive medicine and the environmental conditions of cage-free systems on animal health and final egg quality.

México es el principal consumidor de huevo a nivel mundial con más de 23.22 kg de huevo per capita al año. En años recientes se han diversificado los sistemas de producción con la introducción de sistemas que promueven el bienestar animal. El presente estudio se realizó con el objetivo de comparar la calidad de los huevos producidos en un sistema de corral al aire libre contra los de un sistema semi-tecnificado en jaula. Se evaluaron las características físicas internas y externas de los huevos a los 3 y a los 15 días de la puesta. Los resultados del presente estudio mostraron que el huevo producido en un sistema de corral al aire libre posee menor limpieza (P<0.001), y menor calidad (P<0.005) que el de los huevos producidos en el sistema de jaula, de acuerdo a la clasificación de la Norma mexicana de “Productos avícolas -huevo fresco de gallina- especificaciones y métodos de prueba” (NMX-FF-127-SCFI-2016). Finalmente, el tiempo de almacenamiento disminuyó significativamente la calidad del huevo producido en el sistema de corral al aire libre (P<0.001), pero no la de los huevos provenientes del sistema convencional en jaula. En conclusión, bajo las condiciones del presente trabajo, la calidad del huevo proveniente de sistemas convencionales es mejor que la del huevo producido en sistemas de corral al aire libre, especialmente después de 15 días de almacenamiento. Estos resultados sugieren que se requieren más estudios que evalúen los efectos de las prácticas de manejo, la medicina preventiva y las condiciones medioambientales de los sistemas libres de jaulas, sobre la salud animal y la calidad final del huevo.
