| description |
In order to associate the size of sexual ornaments with reproductive and productive characters in hens from the three-way cross Campero Casilda, the comb [CI: length x height] and wattle indices [BI: length x width] were calculated. Individual data were graphed in a Cartesian system (X: IC; Y: IB) which was divided into four quadrants by two lines that intersect each axis at the level of their mean values. Birds with extreme values of both indices [Quadrant I (CI):> CI> IB and Quadrant III (CIII): <CI <IB] were identified and, for each of them, the productive characters at sexual maturity, four indicators of bone development at 30 and 71 weeks, the dynamic patterns of body weight and egg weight and the ratio of feed conversion to eggs in the first part of the laying cycle, were recorded. Birds with greater development of sexual ornaments (a) were precocious and began laying with eggs of lower weight, but with similar regularity and uniformity and presented (b) greater length of the tarsus and femur in both ages, greater diameter of the tarsus at 30 weeks and greater length of the tibia at 71 weeks of age, (c) higher exponential growth rate between the sixth and twentieth week but similar global growth pattern, (d) lower asymptotic egg weight, lower maturation rate for the character and lower theoretical weight of the first egg and (e) higher number of eggs of lower weight and similar feed conversion ratio between 26 and 35 weeks. Size combination of sexual ornaments is presented as an alternative for the early selection of the breeders. |

Individual data were graphed in a Cartesian system (X: IC; Y: IB) which was divided into four quadrants by two lines that intersect each axis at the level of their mean values. Birds with extreme values of both indices [Quadrant I (CI):> CI> IB and Quadrant III (CIII): <CI <IB] were identified and, for each of them, the productive characters at sexual maturity, four indicators of bone development at 30 and 71 weeks, the dynamic patterns of body weight and egg weight and the ratio of feed conversion to eggs in the first part of the laying cycle, were recorded. Birds with greater development of sexual ornaments (a) were precocious and began laying with eggs of lower weight, but with similar regularity and uniformity and presented (b) greater length of the tarsus and femur in both ages, greater diameter of the tarsus at 30 weeks and greater length of the tibia at 71 weeks of age, (c) higher exponential growth rate between the sixth and twentieth week but similar global growth pattern, (d) lower asymptotic egg weight, lower maturation rate for the character and lower theoretical weight of the first egg and (e) higher number of eggs of lower weight and similar feed conversion ratio between 26 and 35 weeks. Size combination of sexual ornaments is presented as an alternative for the early selection of the breeders. Con el objetivo de asociar el tamaño de los ornamentos sexuales con caracteres reproductivos y productivos en gallinas del cruzamiento de tres vías Campero Casilda se calcularon, en 97 aves de 30 semanas, los índices de cresta [IC: longitud x alto] y barbilla [IB: longitud x ancho]. Los datos individuales se graficaron en un sistema de ejes cartesianos (X: IC; Y: IB) el que se dividió en cuatro cuadrantes mediante dos rectas que intersectan a cada eje a nivel de los valores medios. Se identificaron las aves con valores extremos de ambos índices [Cuadrante I (CI): > IC > IB y Cuadrante III (CIII): < IC < IB] y, para cada una de ellas, se registraron los caracteres productivos a la madurez sexual, cuatro indicadores de desarrollo óseo a las 30 y 71 semanas, los patrones dinámicos del peso corporal y el peso del huevo y la relación de conversión en huevos en la primera parte del ciclo de postura. Las aves con mayor desarrollo de los ornamentos sexuales (a) fueron más precoces y comenzaron la postura con huevos de menor peso, pero con similar regularidad y uniformidad, presentando (b) mayor longitud del tarso y del fémur en ambas edades, mayor diámetro del tarso a las 30 semanas y mayor longitud de la tibia a las 71 semanas de edad (c) mayor tasa de crecimiento exponencial entre la sexta y la vigésima semana pero similar patrón de crecimiento global, (d) menor peso asintótico del huevo, menor tasa de maduración para el carácter y menor peso teórico del primer huevo y (e) mayor número de huevos de menor peso y similar relación de conversión entre las 26 y 35 semanas. La combinación del tamaño de los ornamentos sexuales se presenta como una alternativa para la selección temprana de los reproductores.
