The aim of this study was to evaluate the effect of supplementation with oregano essential oil in the quail diet on the performance and oxidative stability of the egg. A total of 300 quail, 110 days old, were distributed in five groups: Control (diet without supplementation), E&C (diet plus 0.01% enramycin and 0.025% colistin sulfate) and treatments A, B and C (diets supplemented with 100, 150 and 200 mg/kg of oregano essential oil, respectively). The study was carried out for 12 weeks. The oxidative stability of the egg yolk was evaluated on days 0, 7 and 15 of storage. The results showed that dietary supplementation with essential oil of oregano improved productive parameters compared to control (p<0.05), although it was surpassed by E&C. Group A (100 mg/kg) decreased lipid peroxidation in egg yolk on days 0 ...

El objetivo de este estudio fue evaluar el efecto de la suplementación con aceite esencial de orégano en la dieta de codornices sobre el rendimiento y la estabilidad oxidativa del huevo. Se utilizaron 300 codornices de 110 días de edad, distribuidas en cinco grupos: Control (dieta sin suplementación), E&C (dieta más 0.01% de enramicina y 0.025% de sulfato de colistina) y tratamientos A, B y C (dietas suplementadas con 100, 150 y 200 mg/kg de aceite esencial de orégano, respectivamente). La administración de los tratamientos se realizó durante 12 semanas. La estabilidad oxidativa de la yema de huevo se evaluó en los días 0, 7 y 15 de almacenamiento. Los resultados mostraron que la suplementación dietética con aceite esencial de orégano mejoró los parámetros productivos en comparación al control (p<0.05), aunque fue superado por E&C. El grupo A (100 mg/kg) dismin...

The aim of this research was to determine the effect of dietary oregano essential oil (OEO) at performance and oxidative stability; were evaluated 240 quails of 110 days old were divided into 4 groups. One of the groups was given the control diet with antibiotics (0.01% enramycin and 0.025% colistin sulfate) and other groups with 100, 150 and 200 mg/kg levels of supplementation of oregano essential oil supplements for 12 weeks. Quail performance and the oxidative stability of egg yolk with 0, 7 and 15 days of storage were determined. The results show that the diet supplemented with OEO 200 mg/kg exerts positive effects on feed intake in quail (p < 0.05), the control diet and the OEO diet 200 mg / kg were higher in egg production and feed conversion (p < 0.01), referring to egg weight and egg mass, no statistical differences were found (p > 0.05), finally the OEO diet 200 mg / kg obtained...
