Birds were raised incages and randomly distributed into 5 treatments with 3 riplicates/ treat and 20 birds per riplicate, birds exposed to the temperature droah( 28-36-28)˚C. Treatments as follows : T1: Control treatment (without addition) . T2 : Control diet with addition of Betaine at rate of 500mg /kg . T3 : Control diet with addition of Betaine at rate of 1000 mg /kg . T4 : Control diet with addition of Betaine at rate of 1500 mg /kg . T5 : Control diet with addition of Betaine at rate of 2000 mg /kg . The results were as follows: There was a significant (p<0.01) superiority in dressing percentage for birds treated with betaineas compared with those of control treatment . A significant (p<0.01) superiority in theweigh of Chest muscle was also noticed for birds of T2 and T5 as compared with those of T1 and T4 .
