The rearing of Creole backyard chickens constitutes an important economic resource that contributes to food security in Ecuador (Tolombo, 2020). However, its conventional ways of crossing suppose a high genetic variability (Wang et al., 2020). The extensive management of traditional poultry farms (in backyards) has facilitated high inbreeding between hen populations, in such a way that the same individual has common characteristics of several biotypes (Villacís et al., 2016). In Ecuador, three main biotypes (lines) of Creole roosters have been morphometrically identified: the barbona, Cuban and guarica. In this sense, it is a priority to identify these biotypes of Creole roosters in order to develop selection and improvement programs, for t...
