In this study effect of different levels of zeolite on digestibility and some blood parameters in Arabic lambs investigated. In this experiment a change-over design with eigth Arabic lambs with an average live weight of 35±2 selected. Foure rations and foure period was employed. The 4 treatments were: control groups, C+ 3%, C+ 6% and C+ 9% zeolite. The rations were fed to lambs as total mixed feed offered and orts and fecal samples were recorded daily. Blood samples were collected on the end of each period. Plasma glucose concentration was not significantly affected by treatment but tended to be lower with added zeolite. Conversely, the dietary inclusion of resulted in a lower plasma urea-N concentration (p<0.05). Intake of DM was higher for lambs receiving zeolites (p>0.05). Digestibility of DM was lowered with added zeolite (p<0.05). Digestibility of CP and NDF were increased by inclusion of 6% zeolite. This difference was significant (p<0.05) but digestibility of ADF was not significantly affected (p>0.05).
