The objective of this study was to determine the effects of supplemental betaine and choline on productive performance of broiler chickens. A total of 240 oneday old of Ross strain unsexed chicks were randomly distributed into four treated groups: T1control group (basal diet without any addition)?T2, T3and T4 were content basal diet plus 6000 PPM betain and 0.5,1.0,1.5 gm choline / kg feed respectively. The results showed that the diet with 6000 PPM betaine supplementation plus 1.5gm choline/ kg feed increased )P <0.05(live body weight ?body weight gain ,and the feed conversion ratio at (2-5) week of age, however feed consumption during the 3rd to the 5th weeks of age. Meanwhile an improving in dressing percentage and reducing in mortality rate of birds were seen during the completely rearing period.
