Abstract :
Two hundred and forty Hubbard Classic broiler chicks were used in a 35 day trial at Chittagong Veterinary and Animal Science University farm, Bangladesh to study the effects of supplemental choline chloride on performance parameters, carcass characteristics and their association in commercial broiler. All birds had free access to ad libitum feeding. Birds were fed four types of diet i.e. diet without choline chloride (T0), diet containing 0.1 g / 100 g choline chloride (T1), 0.2 g / 100 g choline chloride (T2) and 0.3 g / 100 g cho-line chloride (T3). Results indicated that weight gain differed (P < 0.05) at 5th week irrespective of the level of supplemental choline. Similar to weight gain, feed intake also differed (P < 0.05) at 5th week. However, feed conversion ratio differed from the 3rd to the 5th weeks. Weight gain and feed intake were positively correlated and feed conversion ratio was negatively correlated with carcass parameters. It could therefore be inferred that increasing levels of supplemental choline may progressively improve weight gain, feed effi-ciency and carcass characteristics in commercial broiler.
