Enhanced feed use of sugarcane byproducts is imperative to improve livestock productivity and reduce production cost in Ethiopia. Four successive studies were conducted. The production and utilization of sugarcane byproducts in Wonji-Shoa and Metehara Sugar Estates were assessed by interviewing farm households (n, 308) and collecting secondary data. Green and burnt sugarcane tops (SCT) (variety N-14) were conserved as silage and hay and evaluated for quality. The green and burnt SCT were ensiled with or without 4% molasses, 1% urea and 1% urea + 4% molasses in mini-silos for 45 days. In the hay experiment, the green and burnt SCT were dried (15% moisture) by applying three drying methods (shed and sun-drying of intact SCT and sun-drying of chopped SCT). An experiment was also conducted to evaluate performances of Arsi-Bale lambs consumed diets based on burnt SCT silage or hay, replacing natural pasture hay at 0, 33 and 67% (on dry matter (DM) basis) and concentrate supplementation (317 g DM/day). Farm households using SCT as feed were high (Wonji-Shoa-100%; Metehara- 100%), moderate for molasses (53; 0.9%) and negligible for bagasse (0; 1.8%). The total production volume (on wet bases) of sugarcane byproducts was in the order of bagasse>SCT>molasses and generally higher in Metehara than in Wonji-Shoa. Availability and feed use share of the burnt SCT surpassed green SCT, which coincided with the critical feed shortage period. The prices of the burnt and green SCT in Metehara (297.86 and 195.5 Birr/cart) were three-fold more than in Wonji-Shoa (P5). Total DM loss (2.31%) and temperature (26ËšC) were low (P
