Abstract: We conducted this research to determine dry matter digestibility of triticale grain, barley grain and naked barley grain by using in vitro Tilly and Terrey (TT) technique. A simple technique for the determination in vitro of digestibility of small (0.5 g) samples of dried cereal grain. It involves incubation first with rumen liquor and then with acid HCL and pepsin enzyme. In vivo digestibility (Y), the regression equation Y = 0.99 X-1.01 (SE±2.31) has been calculated, where X = in vitro digestibility. An experiment was carried out in a complete randomized design with 3 experimental groups and 9 replications per groups. The treatments were included triticale grain, barley grain and naked barley grain. Analysis of variance was performed with SAS software and the differences among means were evaluated by using the Duncan's tests. According to these results, in vitro and in vivo digestibility of triticale grain were more significantly than barley grain and grain (p<0.01). The result of this experiment indicate increasing digestibility as substitute triticale grain instead of barley grain.
