ABSTRACT
Six combinations of the tree foliage leaves, Cassava (CL), Acacia Saligna (ASL) and Prosopis juliflora (PL) were tested, CL (100%), ASL (100%), PL (100%), CL plus ASL (50:50), CL plus PL (50:50) and CL plus ASL plus PL (50:25:25), respectively. Then these six combinations were mixed with ammoniated rice straw (ARS) (50: 50) on dry matter basis. Protein content in tested plants was higher in CL (22.22%) compared to ASL (16.67%) and PL (17.02%), while protein content in mixtures of tree foliage leaves have close protein contents. The content of NDF and ADF in CL was lower than the rest of plants tested and their mixtures. The lowest amounts of potential-GP and potential-CH4 were shown with diets containing CL (T1) and ASL (T2) with ammoniated rice straw, while mixing the leaves of CL with ASL and/or PL raised the quantities of GP and CH4 released. Combination of foliage leaves with ammoniated rice straw in T4, T5 and T6 diets significantly (P
