Daily feed intake (mean and standard error) of growing rabbits fed the M diet (following current nutritional recommendations for growing rabbits, including 8.1, 5.8 and 6.9 g/kg dry matter (DM) of total lysine, sulphur amino acids and threonine, respectively) and the H diet (with higher levels of total lysine, sulphur amino acids and threonine: 9.4, 6.6 and 7.8 g/kg DM, respectively) during the five-week choice-feeding trial, as well as during the whole growing period (global). ^a,b Means within different letters were significantly different (p < 0.05). Week 1 (28–35 days), week 2 (35–42 days), week 3 (42–49 days), week 4 (49–56 days) and week 5 (56–63 days).
