results and conclusions – DMI at different times did not differ between treatments. Mean (±SEM) group DMI were 81.48±6.5 and 88.76±7.0, on day 89, and 122 of the study, respectively. By contrast in term of growth performance, results obtained in the present study indicated that choline supplementation increased (P�.05) body weight (BW) and average daily gain (AD�) on day 89 of the experiment but not later on. Feed conversion rate (FCR) and killing out percentage did not differ between treatments through the experiment. Mean feed conversion rate were 6.5 and 6.8 on day 89, and 122, respectively. Killing out percentage was 59% vs 60% in CRT and RPC group, respectively.
