Abstract: This experiment was carried out to evaluation usage different levels of Choline Chloride Supplement (CCS 60%) (0, 500 and 1000 mg kg-1) in the basal diet (corn and soybean meal) and their effects on the different parts of carcass weight (breast and thigh) and internal organs weight (liver, heart, spleen, gizzard, proventriculus and abdominal fat) in broiler chick�s. A total of 90 Ross 308 strain mail broiler were randomly divided in to 3 experimental treatments with 3 replicates (10 chicks per pen) and arranged in a completely randomized design. The experimental period lasted 6 weeks and during this period, the birds had free access to feed and water. Experimental diets consisted of: Basal diet 0 mg kg-1 choline chloride supplement, basal diet with 500 mg kg-1 choline chloride supplement and basal diet with 1000 mg kg-1 choline chloride supplement. These diets were isonitrogenous and isoenergetic were given to broiler chickens throughout a 42 day growth period. Data was analyzed with one way ANOVA and means compared with Duncan test. Three male birds selected with each pen and slaughtered. Result showed choline chloride supplement in all levels not significantly effects on the chilled carcass weight, breasts, thighs, gizzards and proventriculus weight. But, result showed choline chloride supplement in levels of 1000 and 500 mg kg-1 (T3 and T2, respectively) significantly decrease the livers, spleen, hearts weight and abdominal fat deposition (p<0.0001) in relationship to basal diet, as the 3 treatment include of 1000 mg kg-1 has a highest effects.
