Two experiments were conducted to study the performance and carcass quality of broilers in response to varying composition of a diet low in ME, through the supplementation of graded levels of soybean oil. In an initial study, isocaloric (2,965 kcal-kg) and isonitrogenous (21.7percent) corn-soybean diets were supplemented with 10, 20, or 30 g-kg of soybean oil. In a second experiment, diets containing ME levels of 2,940 and 3,040 kcal-kg were supplemented with soybean oil levels of 20 or 40 g-kg. In both experiments, supplementation of up to 30 or 40 g of oil-kg of diet resulted in increases of 175 and 120 g (P 0.05) in BW gain and 97 and 91 g (P ≤ 0.06) in ready-to-cook (RTC) carcass weight at 49 d, respectively. There was a linear decrease (P 0.05) in percentage deposition of abdominal fat pad only in diets containing 2,965 (Experiment 1) or 2,940 (Experiment 2) kcal of ME-kg with no significant changes in RTC carcass and whole breast or pectoralis major muscle yields and RTC carcass composition. Improvements in production parameters can be achieved in broiler chickens fed a low ME diet through the addition of moderate levels of soybean oil. ©2006 Poultry Science Association, Inc.
