Diseño de huevos enriquecidos con astaxantina y hierro para reducir anemia infantil en la región Ica
Design of eggs enriched with astaxanthin and iron to reduce childhood anemia in the Ica regionContenido principal del artículo
La anemia y desnutrición infantil son problemas de salud pública en la región. La región de Ica es la principal productora de huevos del país. Modular la dieta para diseñar un huevo fortificado con Hierro y astaxantina podría ser una estrategia que contribuya a combatir este problema de salud pública. En este sentido se planteó el presente estudio con el objetivo de evaluar una dieta suplementada con Fe orgánico y astaxantina y su efecto sobre la composición de Fe del huevo, respuesta productiva y calidad de huevo. Se utilizaron 140 gallinas de la línea DEKALB White de 50 semanas de edad, que fueron distribuidas bajo un Diseño de bloques completo al Azar. Se establecieron cuatro tratamientos: dieta testigo (T-1), dieta con astaxantina (T-2), dieta con Fe orgánico (T-3) y dieta con astaxantina + Fe orgánico (T-4). Se evaluó la respuesta productiva, contenido de Fe en el huevo y calidad de huevo. Para los análisis estadísticos se usó el procedimiento GLM de SAS v 9.4. El consumo de alimento fue significativamente (P<0.05) más alto para la dieta testigo comparado a los otros tres tratamientos. El color de yema fue significativamente (P<0.05) más alto en las dietas con astaxantina. El índice de yema fue más alto con la dieta con astaxantina + Fe orgánico. Las otras características productivas y calidad de huevo no fueron afectadas (P>0.05). Se concluye que la suplementación de astaxantina y Fe orgánico mejoran el índice de yema y color de yema de huevo de gallinas de postura
Anemia and child malnutrition are public health problems in the region. The Ica region is the main egg producer in the country. Modulating the diet to design an egg fortified with iron and astaxanthin could be a strategy that contributes to combat this public health problem. The objective of the present study was to evaluate a diet supplemented with organic Fe and astaxanthin and its effect on egg Fe composition, productive response and egg quality. A total of 140 hens of the DEKALB White line of 50 weeks of age were used, which were distributed under a Randomized Complete Block Design. Four treatments were established: control diet (T-1), diet with astaxanthin (T-2), diet with organic Fe (T-3) and diet with astaxanthin + organic Fe (T-4). The productive response, egg Fe content and egg quality were evaluated. The GLM procedure of SAS v 9.4 was used for statistical analysis. Feed intake was significantly (P<0.05) higher for the control diet compared to the other three treatments. Yolk color was significantly (P<0.05) higher for the diets with astaxanthin. The yolk index was higher for the astaxanthin + organic Fe diet. The other productive characteristics and egg quality were not affected (P>0.05). It is concluded that astaxanthin and organic Fe supplementation improve yolk index and yolk color of laying hen eggs.
