A growth trial was conducted to evaluate the potential of ex decanter solid waste as a feed supplement for fattening sheep. Thirty two ram lambs (16 Sumatra and 16 St. Croix x Sumatra), housed in individual pens, were fed one of four grass based rations varying in content of fresh ex decanter solid waste. The four rations (R0, R1, R2, and R3) were formulated to provide 0; 10; 20 and 30 percent of ex decanter solid waste in the diet on a dry matter basis, respectively. Feed offered in the four rations consisted of 100 percent, 70 percent, 60 percent, and 50 percent Brachiaria sp., respectively. Total feed on offer in each ration was standardized at 3.5 percent of body weight on a dry matter basis. Lambs averaged 21.8 +- 3.8 kg at the start of the experiment. A metabolism trial was conducted to measure the digestibility of dry matter, crude protein and energy of each diet. Average daily gains were significantly different (P 0.05) in the order R0 (29.9 g/day) R1 (58.3 g/day) and R2 (64.6 g/day). ADG for R3 (70.0 g/day) was significantly higher (P 0.05) than R0 and R1. This improvement was likely the result of the higher dry matter, energy and protein intake on the diets with ex decanter solid waste. Digestibilities of ex decanter solid waste are relatively high (66, 58, and 65 percent for dry matter, protein, and energy, respectively)
