Abstract

This study was carried out to the determination of nutritive value of barley grain (un treateated and treated with 120º C heat) using nylon bag technique in Gizel sheep . Tow fistulae Gizel sheep with average BW 50.5±2.5 kg used in a complete randomized design. The ruminal DM disappearance were measured 0, 4, 8, 16, 24, 36 and 48 h. Dry matter degradability of barley un treateated and treated grain at 48 h were 73.62 and 66.37%, there were higher and lower respectively, that showed significant differences (p<0.05). Results of DM degradability characteristics showed that modelIII was the best fit to barley grain DM disappearance.
