This study evaluated the performance of sheep raised on Tanzania grass under intermittent stocking with four supplementation proportions 0; 0.6; 1.2, and 1.8% of live weight (LW) and eight replicates, in a completely randomized design with tree grazing periods, and 21 rest periods. The average daily gain (GMD), the total weight gain (GPT), the days to reach 12kg (D12), the stocking rate (sheep/ha - TLO and animal unit/ha - TLUA), the live weight yield (RPV), and the concentrate: gain ratio (CAC) was evaluated. It was observed a square effect of supplementation proportions on GMD, estimated in 65.87 and 113.15g/day for male sheep that was not supplemented and received 1.8% LW supplement. It was observed a square effect of supplementation level on GPT. The D12 to 0% LW level was estimated in 204 days, decreasing to 113 days when the sheep received 1.8% LW supplement. It was observed square effects of supplementation proportions on TLO and TLUA. It was observed a negative linear effect of supplementation proportions on RPV. The CAC presented the best response for sheep that received 0.6% LW supplementation proportion. It can be concluded that sheep supplementation until 1.2% LW level provided improvement on performance of grazing sheep.
