Abstract
The minimum total lysine requirement for pigs between 80 and 120 kg has been reported as 0.65g/kg (National Research Council, 1998) whilst the current recommended lysine requirements for pigs fed a diet supplemented with ractopamine (RAC) is 0.70g/kg of total lysine (approximately 0.56g available lysine/MJ digestible energy (DE)). More recently (Rikard-Bell et al., 2009) reported that the improvements in growth performance elicited by RAC were similar for pigs offered diets with 0.56 or 0.65 g available lysine/MJ DE. The aim of this experiment was to investigate the performance responses of finisher pigs offered a wider range of dietary lysine levels and three levels of dietary RAC.
