Caracterización morfológica de la gallina de campo de la región interandina del Ecuador

Abstract

At the Tunshi Experimental Station, Licto parish, Riobamba canton, a hundred field hens from Ecuadorian highland provinces, exception of Carchi and Imbabura (Agricultural Census of 2010) were morphologically characterized. The zoometric measurements data were analyzed by descriptive statistics, getting an alive weight (1.957 grams); head length (6.43 cm); head width (3.41 cm); ear length (2.32 cm); width of earrings (0.29 cm); crest length (3.78 cm); crest width (3.40 cm); peak length (3.27 cm); neck length (14.15 cm); dorsal length (22.58 cm); ventral length (24.09 cm); femoroilioischiatic width (8.61 cm); chest perimeter (34.77 cm); wing length (19.61 cm); proximal wing length (8.08 cm); length of the middle wing (8.62 cm); distal wing length (6.78cm); length of thigh (10.91 cm); leg length (12.78 cm); leg circumference (10.74 cm): length of reed (8.03 cm); length of the middle finger (5.61 cm); length of spur (0.40 cm). Defining to Loja with an obvious superiority in zoometric measures, except for: ears length (Bolivar), crest width (Pichincha), peak length (Azogues), ventral length (Tungurahua), femoroilioischiatic width (Chimborazo); distal wing length (Bolivar), leg circumference (Tungurahua); showing that within the region there is no homogeneity, and that thanks to this variability it would allow the creation of productive lines with rusticity. Therefore it is recommended to carry out genetic analysis based on molecular marks to consider that a group of poultry belongs to the creole biotype.
