Effects of supplemental choline on deposition of cardiac, hepatic and abdominal fat in broiler

Abstract

Two hundred forty Hubbard Classic broiler chicks were used in a 35-day trial to study the effects of supplemental choline on deposition of cardiac, hepatic and abdominal fat in broiler. Birds were fed four types of diet: control diet without choline chloride (T₀), diet containing 0.1% choline chloride (T₁), 0.2% choline chloride (T₂) and 0.3% choline chloride. All birds had access to feed and water ad libitum. Results indicated that, trends for deposition of cardiac, hepatic and abdominal fat was decreasing (P<0.01) in a linear fashion both at 4^th and 5^th weeks as the level of supplemental choline increased linearly. Maximum deposition of cardiac, hepatic and abdominal fat was observed in birds fed the control diet (T₀) and the mean values were 24.4, 34.9 and 4.1 at 4^th week and 41.6, 47.8 and 6.2 at the 5^th week. In contrast, minimum deposition of cardiac, hepatic and abdominal fat was observed in birds fed diet supplemented with 0.3% choline chloride (T₃) and the mean values were 14.5, 19.8 and 1.74 at 4^th week and 27.2, 27.8 and 2.2 at 5^th week. It was concluded that increasing levels of supplemental choline substantially reduced deposition of cardiac, hepatic and abdominal fat in commercial broiler.
