Abstract: This study was conducted to determine the effects of sodium bicarbonate and dry yeast in TMR with cassava peel on intake, nutrients digestibility and rumen fermentation of finishing lamb. Eight crossbreed lambs (Santa Inêsx Dorper x Indigenous) were randomly assigned into a 2×2 factorial arrangement in replicated Latin square design. They were given a total mixed ration as control diet (NA) at ad libitum daily feeding/lamb supplemented with 0.5% of Sodium Bicarbonate (SB) or 0.2% of dry Yeast (Y) or combination (Y/SB) during a 21-d experimental period. The results showed that dry matter intake and dry matter intake per body weight was significantly higher in Y and Y/SB than control and SB (p<0.05). Digestibility of dry matter, crude protein and NDF of Y and Y/SB were significantly higher than control (p<0.05). Ruminal pH, NH3-N and total volatile fatty acid components of Y group were significantly higher than those control (p>0.05). It is suggested that supplementation of Y in diets containing high level of cassava peel did not affect voluntary feed intake of lamb but it could buffer the rumen pH and improving digestibility of nutrients and bacterial growth.
