Abstract :

Oxymetholone at 0.6 mg/kg feed or mixed with ZnSO (45mg/kg feed), testosterone at 10 mg/kg 4
feed or mixed with ZnSO (45 mg/kg feed) and 0 mg/kg of either one were given to 180 turkey chicks (n = 9; 4 r = 4) from 6-18 weeks of age to determine their effects on growth performance. Body Weight (BW) was
increased gradually in all treatments when compared to the control group with the highest level for
oxymetholone and testosterone alone respectively. Feed Intake (FI) during 12 weeks of study decline slightly in all treatments with the lowest level for oxymetholone + ZnSO and the highest level for control group. Feed 4 Conversion Ratio (FCR) at the end of study was 4.77 for control group and 4.15, 4.32, 4.50 and 4.69 for different treatments, respectively. Growth Rate (GR) differed for each week and treatment. Overall, the treatment groups showed higher GR when compared to control group in every week. The percentage of  Carcass Weight (%CW) was increased significantly (p<0.05) in all treatments in comparison with control group with highest level for testosterone + ZnSO . The treatments did not influence significantly on the 4 internal organs by the end of study. Oxymetholone induced BW and %CW (p<0.05) with less FI and FCR when compared to testosterone and control group in turkey chicks.
