Genetic parameters for egg number, egg weight, and eggshell color in three Catalan poultry breeds.

Poultry science - 1 Dec 1997

Francesch A, Estany J, Alfonso L, Iglesias M

Abstract excerpt

Heritabilities for egg number, egg weight, and eggshell color (percentage light absorbance) at 39 wk of age, and the genetic correlations between them were estimated by restricted maximum likelihood in three Catalan poultry breeds: Penedesenca Negra (PN), Prat Lleonada (PL), and Empordanesa Roja (ER). Additive genetic differences between these breeds were also estimated. Data were from the IRTA Poultry Genetic...
