Forty barrows from commercial hybrids averaging initial weight of 60.1 ± 1.3 kg were used in a trial to evaluate different ME levels, maintaining the digestible lysine:calorie ratio, on the performance and carcass characteristics. A randomized block experimental design with four treatments, five replicate and two animals per experimental unit was used. The treatments consisted of four ME levels (3,100, 3,230, 3,370, and 3,500 kcal/kg) with 2.41 g of digestible lysine/Mcal of EM ratio. Animals were fed until the end […]
