ABSTRACT
Body weight and nine morphostructural characters (withers height, rump height, heart girth, body length, head width, cannon circumference, shoulder width, rump width and rump length) of 83 White Fulani cows aged 1.5-2.4 years old were used to study the problem of multicollinearity instability in the estimation of body weight from morphological indices. Pairwise phenotypic correlations indicated a high and positive significant relationship between body weight and body dimensions (r = 0.61- 0.94; P
