The goals of these trials were to investigate the effects of different dietary amino acid concentrations and valine:lysine ratios on piglet performance and health. Two 4-week trials with 90 weaned piglets (3 treatments and 6 replicates) each were conducted. All diets contained 14 MJ DE: Trial 1: (i) 180 g CP, 12,5 g lysine, 8,6 g valine; (ii) 165 g CP, 11,5 g lysine, 7,9 g valine; (iii) 165 g CP, 11,5 g lysine, 8,5 g valine. Trial 2: (i) 180 CP, 12,4 g lysine, 8,6 g valine; (ii) 165 g CP, 12,4 g lysine, 7,9 g valine; (iii) 165 g CP, 12,4 g lysine, 8,6 g valine. In trial 1, the higher crude protein and amino acid concentrations led to a significant improvement in FCR (1,43a vs 1,53b and 1,51b kg/kg; P<0.05). Increasing the amino acid concentrations in the treatment with reduced CP concentration allowed performance to be maintained at the level of the standard diet in trial 2. The supplementation of the essential amino acid valine did not affect animal performance.
