This study was carried out to the determination of nutritive value of Orange pomace (untreated and treated with 2% urea) using nylon bag and gas production techniques in Gizel sheep . Tow fistulae Gizel sheep with average BW 35±1.8 kg used in a complete randomized design. Ruminal CP disappearance were measured 0, 2, 4, 8, 12, 24, 36and 48 h. Crude protein degradabilities of Orange pomace at 0 and 8 h for untreated urea were 8.30 and 21.32%, and for urea treated samples were 12.81 and 23.91 % respectively that showed significant differences (p<0.05). Solubility of dietary N has been considered to be a factor influencing protein degradation in the rumen at interesting times.
