In this work is done an approach to the productive characterization of the breed sobrarbe hen, so much in the growth (study of the growth, indexes of conversion and carcass) as in the lay phase (number and quality of eggs). The males reached 2,1 kg of live weight at 19 weeks of life, with an index of conversion of 4,5 and a performance of the eviscerated carcass close to 83 %. Hens started laying at 20 weeks of age, with an annual result of 170 eggs. significant differences between varieties were only observed in the Haugh Units.
