The GIs analyzed were VH = very high, H = high, L = low, and VL = very low, and were represented by the residual leaf area index (LAIr).
The lambs were divided into two groups, supplemented (SP) and non-supplemented (NSP).
The dry matter intake (DMI) and average daily gain (ADG) increased linearly with decreasing GI (P 0.05), and the ADG was higher for the NSP group than the SP group (P 0.05...
