An experiment was conducted to determine different levels of EM-bokashi® and MEM solution inclusion in supplemental diets of local sheep in Ethiopia. 25 yearling male Afar sheep with a BW of 18.8kg ± 1.6kg were used in the study with RCBD design. Five sheep were randomly assigned to each of the five dietary treatments that consisted of ad libitum tef straw + concentrate (300gm/head/day) + no supplementation (T1), and supplementation of EM-bokashi® with 1% (T2), 3% (T3) and 5 % (T4) on dry matter (DM) basis and 14% (T5) MEM solution and concluded that EM™ could be included preferably in its MEM solution form than bokashi at 14% or more in the ration of sheep.
