Body Length (BL), Heart Girth (HG), Rump Height (RH), Rump Width (RW), Ear Length (EL), Cannon Circumference (CC) and Heard Width (HW) and to establish a model for the prediction of BW using linear body measurement traits. Pearson correlation results indicated that BW in Boer goats had a positively high statistically association (P<0.01) with BL (r = 0.86**), HG (r = 0.89**), RH (r = 0.75**), CC (r = 0.58**) and HW (r = 0.65**). Furthermore, the results showed that BW in bucks had a positively high statistical correlation (P<0.01) with BL (r = 0.62**), HG (r = 0.83**), RH (r = 0. 56**) and HW (r = 0.51**) and a positive statistical correlation (P<0.05) with RW (r = 0.31*) and CC (r = 0.36*), as well as a negative statistical association (P<0.05) with EL (r = -0.25*). The regression results suggest that improving BL and HG might result in the improvement of BW in Boer goats.
