Estudio comparativo de la calidad interna del huevo en tres genotipos de ponedoras camperas.

Abstract

Comparative study of the internal egg quality in three genotypes of free-range layers. The internal quality of the eggs laid by three genotypes of hens destined for semi-intensive systems: the three-way cross Campero Casilda, the self-sexing layer Negra INTA and a Rhode Island Red strain was evaluated. Between 26 and 70 weeks of age random samples of 15 eggs from each group were removed at regular intervals of four weeks. In each egg, the height and the greater and lesser diameters of the yolk and the height, length and width of the albumen were measured. As indicators of internal quality, the yolk and albumen indices and the Haug units were calculated. The dynamic pattern of the three indicators and the variables involved in their calculation was evaluated by non-linear and linear regression on hens age. The eggs of the three genetic groups presented a high internal quality, which was maintained throughout the laying cycle without differences in the indicators related to the albumen but with a more advantageous behavior of the yolk component in the case of the three way cross Campero Casilda, which valorizes ​​it as a dual-purpose option for semi-intensive systems.

Se evaluó la calidad interna de los huevos puestos por tres genotipos de gallinas destinadas a sistemas semi-intensivos: el cruzamiento de tres vías Campero Casilda, la ponedora autosexante Negra INTA y una estirpe Rhode Island Red. Entre las 26 y las 70 semanas de edad se extrajeron, a intervalos regulares de cuatro semanas muestras aleatorias de 15 huevos de cada grupo. En cada huevo se midió la altura y los diámetros mayor y menor de la yema y la altura, longitud y ancho del albumen. Como indicadores de la calidad interna se calcularon los índices de yema y albumen y las unidades Haugh. El patrón dinámico de los tres indicadores y de las variables que intervienen en su cálculo en función de la edad de las aves se evaluó por regresión no lineal y lineal. Los huevos de los tres grupos genéticos presentaron una elevada calidad interna la que se mantuvo a lo largo de todo el ciclo de postura sin diferencias en los indicadores vinculados con el albumen, pero con un comportamiento más ventajoso del componente yema en el caso del cruzamiento de tres vías Campero Casilda lo que lo valoriza como ave doble propósito para sistemas semi-intensivos.
