Abstract

The recommended standardised ileal digestible (SID) ratio of tryptophan to lysine (Trp:Lys) is 0.16 for 7-11 kg pigs (NRC, 2012). However, Simongiovanni et al. (2012) showed the requirement for dietary Trp increases during inflammatory states, such as in the post-weaning period, suggesting that NRC (2012) recommendations might be insufficient. This study hypothesised that weaner pigs kept in commercial conditions will show a positive response to increased Trp:Lys ratios above the NRC (2012) recommendations.
