Biometric characterization of local chicken “Gallus gallus domesticus” according to the sex and phenotype from traditional breedings of Dabakala (Côte d’Ivoire)

Abstract— A study having for objective the biometric characterization of the local chicken according to the sex and the type of feathering was conducted in the department of Dabakala. A sample of 116 local reared chickens (39 cocks and 77 hens) from traditional breeding was the object of a description by observation, weighing and physical measurement. This study has shown a sexual dimorphism between the cock and the hen. Thus cock’s average weight was 1571.79 ± 60.69 g against 1120.78 ± 29.70 g for the hen. The whole population of chicken weight average was 1272.41 ± 34. 51 g. The eight (8) biometric traits studied were distributed in five (5) phenotypes and three (3) subgroups according to the number of common traits. The biometric parameter that could best serve the determination of body weight of a chicken without actually weighing it, was thoracic perimeter with better correlation with weight.

Keywords Dabakala, biometric characterization, traditional breeding, local chickens.
