Abstract

The study was conducted in Katsina-Ala local Government Area of Benue State, in four villages
each with a minimum distance of thirty kilometers apart. Body linear measurement and body
weight were measured on 1378 adult chickens. The data generated were subjected to
discriminant analysis.Discirminant function models were utilized to estimate canonical
discriminant functions, canonical correlation coefficients and structure matrix. The
discriminating power of tail width (TW) was the highest followed by shank length (SL), tail
length (TL), comb height (CH) and thigh length (THL).These five variables have large
canonical discriminant coefficients with strong discriminating power which aided the allocation
of the chicken populations to the four groups. The five variables showed strong discriminating
power that can be used on the field for characterization, to differentiate and identify phenotypic
variability between populations of local chicken ecotype.
