Evaluation of cassava foliage as a protein supplement for sheep

Three trials were conducted to evaluate the potential of cassava (Manihot esculenta) foliage (leaves and petioles) as a protein supplement for sheep. In the first trial, nylon bag degradability of cassava foliage was studied. Proximate analysis of cassava foliage was conducted before and after the incubation. Rumen Ammonia Concentration (RAC) and pH were determined at 0, 4 and 8 hours after feeding cassava foliage diet (30%). Proximate composition of sundried cassava foliage was (%) DM 91.25, CP 18.55, NDF, 31.41, ADF, 29.2, EE, 6.6, Ash, 12.95. Nylon-bag dry matter disappearance (DMD) increased significantly (P0.05) in the live weight gains of rams on the control diet compared with those supplemented except for those supplemented with cassava foliage and groundnut haulms combined at 1% level where the weight gain was significantly higher (P0.05) affected by feeding either supplement. Supplementing digitaria hay with cassava foliage at both 0.5% and 1.0% BW did not significantly increase the nitrogen retention values, but groundnut haulms supplemented at 1.0% BW significantly (
