| description |
The shape of the eggs laid by three genotypes of hens suitable for semi-intensive systems: Campero Casilda, Negra INTA and Rhode Island Red was evaluated with the aim of studying, with a dynamic criterion, its modification throughout the cycle given its relationship with the resistance to breakage and its aptitude as incubating eggs. Random samples of 50 eggs from each group were collected monthly from 25 to 69 weeks of age. Egg length and width were measured and the shape index (IF= (width / length) x 100) was calculated. Eggs were classified as elongated IF < 72, satisfactory 72 ? IF ?76 and rounded IF > 76. Egg length-age and width-age data were fitted with the Brody function. Shape index-age data were fitted by linear regression. The positive association between shape index and shell strength and the negative association with hatchability determines that rounded eggs have higher strength but less aptitude as hatching eggs and vice versa. As a comparative advantage, Campero Casilda eggs present during a greater proportion of the production cycle a rounded shape associated with a better behavior against breakage, but with the disadvantage of being less suitable for incubation purposes. |

Di Masso, R.J. 2022 Se evaluó la forma de los huevos puestos por tres genotipos de gallinas destinadas a sistemas semiintensivos: Campero Casilda, Negra INTA y Rhode Island Red, con el objetivo de estudiar, con un criteriodinámico, su modificación a lo largo del ciclo de postura dada su relación con la resistencia a la rotura y su aptitud para la incubación. Entre las 25 y 69 semanas de edad se recolectaron mensualmente muestras aleatorias de 50 huevos de cada grupo, se midió su longitud y ancho, se calculó el índice de forma (IF= (ancho / largo) x 100) y se los clasificó en alargados IF < 72, satisfactorios 72 ? IF ?76 y redondeados IF > 76. Los datos longitud y ancho del huevo se ajustaron en función de la edad con el modelo de Brody y los del índice de forma por regresión lineal. La asociación positiva entre el índice de forma y la resistencia de la cáscara y negativa con la incubabilidad determina que los huevos redondeados presenten mayor resistencia pero menor aptitud como huevos incubables y viceversa. Los huevos Campero Casilda presentan como ventaja comparativa durante una mayor proporción del ciclo una forma redondeada asociada a un mejor comportamiento frente a las roturas y como desventaja su menor adecuación como huevos incubables.\n application/pdf ISSN 1668-3498 (en línea) índice de forma longitud del huevo ancho del huevo avicultura alternativa shape index egg length egg width alternative poultry spa Universidad de Buenos Aires.
