ABSTRACT
A total of 180 broiler was supplemented with organic acid (OA) at the rate of 0, (OA-0), 0.5 (OA-0.5), 1 (OA-1), 1.5 (OA-1.5) and 2 ml/l (OA-2) in drinking water during the starter period for 21 days. Feed intake was significantly (P<0.05) lower and weight gain and dressing percentage were significantly (P<0.05) higher in the OA-2 group, resultantly, the best feed conversion ratio (FCR) was recorded in the same group. Tibia dry matter, ash, calcium (Ca) and phosphorous (P) were significantly (P<0.05) higher in OA-2. On the other hand, fecal Ca and P decreased significantly (P<0.05) in OA-2. Mean dry matter and ash contents increased significantly (P<0.05) in OA-2, while crude protein, crude fibre, ether extract and metabolizable energy increased significantly (P<0.05) in OA-1.5 and OA-2. In conclusion, addition of OA in drinking water at the rate of 2 ml/L improved weight gain, feed efficiency, nutrient digestibility, and tibial mineralization of Ca and P in broiler.
