Resumen
The objective of this research was to morphologically characterize the free-range hens in
the province of Orellana using 100 hens from the 4 towns (Loreto, Sacha, Aguarico and
Puerto Francisco de Orellana). The corresponding zoometric measurements were
analyzed using descriptive statistics. The results indicated: live weight (2.84 kg); head
length (6.45 cm); head width (3.7 cm); ear length (2.28 cm); ear width (0.34 cm), crest
length (4.95 cm), crest width (0.72 cm), beak length (3.91 cm); neck length (14.1 cm);
dorsal length (24.74 cm); ventral length (26.78cm); femoroilioischiatic width (10.08 cm);
chest circumference (37.79cm); brim length (23.95cm); proximal wing length (11.5cm);
medium brim length (9.41cm); distal wing length (7.61 cm); thigh length (11.69cm); leg
length (13.63cm); leg circumference (13.29 cm); cane length (8.05cm); middle finger
length (6.19cm); and spur length (0.77cm). It was concluded that hens from Sacha town
showed superiority regarding the zoometric measurements of the free-range hens. It was
demonstrated that within the region there is no homogeneity. Knowing these variabilities
will allow the creation of rustic productive lines, so it is recommended to study, in depth,
the free-range hens to obtain more information on the morphological characteristics to
strengthen the sustainable livestock work.
