Abstract

Investigation on morphological characteristics of 198 normal feathered indigenous chickens of Central part of Borno State, North East Nigeria was carried out using Principal Component Analysis. Value for body weight (g), ornithological measurement (cm), wing span (cm), neck length (cm), back length (cm), keel length (cm), tail length (cm), thigh length (cm) and shank length (cm) were 1491.11, 60.80, 64.36, 13.39, 21.45, 11.99, 20.80, 13.10 and 9.34, respectively. Sexual dimorphism was observed in all the traits as higher values were obtained for males. The first Principal Component (PC 1) accounted for the greatest percentage (46.67 %) and is a descriptor of body weight, ornithological traits and wing span; the second Component (PC 2) accounted for 17.35 % and is a descriptor of neck length, thigh length and shank length; the third Component (PC 3) accounted for 11.12 %, of the total variance and it described keel length.
