The aim of this work was to establish the response of growing sheep, goats and cattle to different nutritional environments. Data from 590 publications representing 2225 treatments were analysed. The results showed that each 10% increase in NDF was accompanied by 0.11 g/kg live weight (LW) and 0.32 g/kg metabolic live weight (LW0.75) decreases in DMI. Otherwise, the response of DMI to CP (CP%DM) content was curvilinear (P1.4, corresponding to maximum growth (HE+)). No significant difference was observed between LE-- and LE-, and no significant difference was observed between ME+- and HE+. For nitrogen balance, no difference was observed between species for a given level of nitrogen intake.
