Pseudo acacia Lespedeza spp., and Pueraria thunbergiana, wild shrubs in the mountainous area were added with concentrate (50:50, W/W), and treated with 6 % ammonia water. Woods silage were fed to growing ram. In rumen propionic acid, control, pseudo acacia, Lespedeza spp., Quercus spp. and Pueraria thunbergiana were 8.79, 11.96, 12.12, 11.49 and 12.59 micro mole respectively. Ammoniated wood silage was significantly increased more than control wood silage (p .05). In rumen total VFA, control, pseudo acacia, Lespedeza spp. Quercus spp. and Pueraria thunbergiana were 61.44, 73.60, 72.06, 70.00 and 73.24 micro mole respectively. Ammoniated wood silage was significantly increased more than control (p.05). Control of blood pH (6.75) was not significantly increased more than ammoniated wood silage (6.69-6.78). Quercus spp. of plasma propionic acid (1.92 micro mole) was significantly decreased and Pueraria thunbergiana significantly increased (p .05). In plasma total VFA, control, psuedo acacia, Lespedeza spp., Quercus spp. and Pueraria thunbergiana were 10.57, 12.51, 10.98, 8.99 and 13.37 macro mole respectively. Plasma total VFA of Quercus spp. was significantly decreased and Pueraria thunbergiana significantly increased (p.05). Urea content of plasma, control, pseudo acacia, Lespedeza spp., Quercus spp. and Pueraria thunbergiana were 45.55, 56.40, 55.13, 52.62 and 59.98mg respectively. Plasma urea of control was significantly decreased and ammoniated wood silage significantly increased (p .01)
