Choline serves several crucial metabolic functions, making it an essential component in poultry diets which include lipid transport, cell signalling, and biosynthesis of methylated compounds. The objective of this study was to evaluate the performance and carcass characteristics of the Cobb 500 chickens fed dietary choline. One hundred- and forty-four-day-old (42.16 +0.15), unsexed Cobb 500 chickens were randomly assigned to three treatment groups with four replications of twelve (12) chicks each in a Completely Randomized Design. Three levels of choline (0, 1200, 1400 ppm/100 kg of feed) were supplemented in the chick's feed at the starter phase (0-21days), while at the finisher phase (21-49 days) three levels of choline (0, 800, 1000 ppm/100 kg feed) were also supplemented in the chicken's feed. Results showed that different levels of choline had no significant effect (P > 0.05) on the weight changes of broiler chickens at the starter and finisher phases. However, the feed conversion ratio was best (P < 0.05) for chicks supplemented with 1200 ppm at the starter phase compared to the finisher phase. At the finisher phase, feed intake (3216.93 g/bird) of birds offered 800 ppm choline were significantly (P < 0.05) reduced when compared to control diets (3380.11 g/bird). Dressing percentage significantly (P < 0.05) increased at 800 ppm while the thigh decreased (P < 0.05) with choline increment. In conclusion, choline supplementation in the diets of broiler chickens at 1200 and 800 ppm/100 kg feed improved the growth performance and carcass characteristics of Cobb 500 broiler strain chickens at starter and finisher phases respectively.
