Summary Three species of grasses (Pennisetum purpureum, Trypsacum laxum and Brachiaria ruziziensis) were used to study the effect of different sources of energy supply on in vitro digestibility of Leucaena leucocephala and Calliandra calothyrsus harvested at the Teaching and the Research Farm of the University of Dschang. The legumes were mixed with grasses in 1:3 (150 mg of legumes and 350 mg of grasses) analysed and incubated. The crude protein (CP) content of L. leucocephala (29%) was higher than that of C. calothyrsus (23.62%). The gas and SCFA production from the degradation of L. leucocephala alone was 39.57ml/200mg DM and 0.88 mmol/40ml viz 27.60ml/200 mg DM and 0.59mmol/40ml from the degradation of C. calothyrsus. In the presence of grasses, gas and SCFA produced from degradation of L. leucocephala varied from 41.02 to 50.77ml/200mg DM and 0.91 to 1.15mmol/40ml viz 39.08 to 42.54 ml/200 mg DM and 0.87 to 0.95mmol/40 ml respectively from the degradation of C. calothyrsus. Metabolizable energy (ME) (9.23MJ/kg DM) and microbial mass (MM) (172,38 mg) produced from the organic matter digestibility (OMD) (63.57%) of L. leucocephala incubated alone were significantly (P
