In a completely randomized design experiment, 60 male turkeys of 8-weeks-old were randomly divided into different levels of terbutaline kg -1 of diet (TE1 = 0 mg kg-1, TE2 = 7.5 mg kg-1 and TE3 = 15 mg kg-1). The period of experiment was 8 weeks. Birds and feed were weighed weekly. At 8th weeks, blood samples taken from four birds per pen for the determination of triiodothyronine (T3), thyroxine (T4) and hematocrit. Hearts were collected from all birds and scored for ascites. Weight and feed intake in birds received oral administration of terbutaline (TE2 and TE3) were significantly higher than control group (p<0.01). Hematocrits were significantly higher in asctic birds (TE1) (p<0.05). Adding terbutaline to the feed significantly reduced ascites mortality (p<0.01). T3 value was not affected by the dietary treatments, but terbutaline reduced significantly the plasma T4 concentration (p<0.05). Right/total ventricular weight ratio (RV/TV) in right ventricular failure turkeys (TE1) was significantly (p<0.01) higher compared with healthy birds (TE2 and TE3). This study showed that supplemented diet with terbutaline (7.5 and 15 mg kg -1) may decrease heart failure syndrome in birds, of course adequate withdrawal times are ensured. © 2008 Academic Journals Inc.
