Result revealed that the daily gain, feed efficiency, dressing percentage based on live body weight, rib eye area and fat thickness, lean, fat and bone percentage averaged 98.73gm, 5.12 kg/kg, 46.96%, 9.44cm2, 1.15 mm, 64.07%, 16.89 % and 19.02 % respectively for Meriz, while the corresponding values for Black goat were 75.58 gm, 6.43 kg/kg, 49.42 %, 12.47 cm2, 1.75 mm, 63.73 %, 16.82 % and 19.44 %, respectively. No significant differences between 90 and 150 days fattening period was observed in all studied traits except some commercial cuts. | ||
