The aim of the study was to evaluate the growth stimulating drugs (GSD) on growth performance, haematology, feed conversion ratio (FCR), dressing % and meat quality of cattle. The GSD had significant effect on daily body weight gain of cattle. The daily average live weight gain by vitamin, Tonic powder, steroids, tonic drugs-parenteral, iodine+UMS and no drugs were 566, 775, 541, 525, 675 and 683 gm/day, respectively. Total erythrocyte count in all treated groups increased significantly. After treatment the Haemoglobin % increases significantly. FCR was lowest (4.90) in tonic powder-oral and highest (7.23) in tonic drugs-parenteral. Significantly the highest dressing (55.57) % was observed in control group and the lowest (45.97%) in group of tonic drugs- parenteral. The dry matter, crude protein, ether extraction and ash values were found to be significantly increased in iodine (parenteral)+tonic powder (oral) group. It is concluded that to increase meat production in a very cheapest way to may be the use of tonic powder-oral (Growth tonic powder, Speed care) + Caldee plus bolus, Speed care) and Iodine-parenteral+UMS-oral (Inj. Lugol´s iodine (2%) solution+UMS) administration.
