The objectives of this study were to compare the performance characteristics of four strains of
broiler chicken from 2 to 8 weeks of age and predict body weight of the broilers using linear body
measurements. The four strains of broiler chicken used were Anak, Arbor Acre, Ross and Marshall. The
parameters recorded were bodyweight, weight gain, total feed intake, feed conversion ratio, mortality and some
linear body measurements (body length, body width, breast width, drumstick length, shank length, thigh length
and wing length). Prediction equations relating body weight to linear body measurements at 2 and 8 weeks of
age were established for the four strains of broilers using multiple regression method. The results indicated
similarity in bod y weight at 8 weeks, weight gain and feed conversion ratio among Anak, Arbor Acre and Ross
broilers. They were however, significantly (p<0.01) superior to Marshal in all these traits. The regression
analysis were highly significant (p<0.001) for the two age periods and in all the strains. The coefficient of
multiple determinants (R2) were more than 50% in most of the groups indicating that the prediction equations
obtained in this study co uld be used to predict body weight of broilers.
