Abstract :The aim of this study was to determine digestibility and energy contents of plants heliz insert ignore into journalissuearticles values(Prangos pabularia); and parzuk insert ignore into journalissuearticles values(Hippomarathrum microcarpum); with in vivo and in vitro methods and also to compare them to traditional. Seven male Red Karaman hoggets were used in the trial. Digestibilities of four different forages were determined with classical and two-stage digestibility methods. Moreover, energy contents of forages were also estimated using both digestibility values. In situ degradation characteristics of these forages were also evaluated. In the in vivo trial for digestibility, the degrees of digestibility of four different forage plants were determined by ‘’missing block trial pattern’’. In vivo organic matter digestibility insert ignore into journalissuearticles values(OMD); of parzuk and heliz insert ignore into journalissuearticles values(75.52% and 73.46%); were higher than those of dried meadow grass insert ignore into journalissuearticles values(68.94%); and dried alfalfa hays insert ignore into journalissuearticles values(65.81%);, insert ignore into journalissuearticles values(P<0.05);. These difference were reflected in energy contents and DE insert ignore into journalissuearticles values(digestible energy); insert ignore into journalissuearticles values(3.33 and 3.24Mcal/kg dry matter insert ignore into journalissuearticles values(DM););, ME insert ignore into journalissuearticles values(2.73 and 2.65 Mcal/kg); and NEL insert ignore into journalissuearticles values(net energy lactation); insert ignore into journalissuearticles values(1.73 and 1.68 Mcal/kg DM); values of parzuk and heliz were higher than those of meadow grass insert ignore into journalissuearticles values(3.04, 2.49 and 1.57 Mcal/kg DM); and dried alfalfa insert ignore into journalissuearticles values(2.90, 2.38 and 1.49 Mcal/kg DM); hays, insert ignore into journalissuearticles values(P<0.05);. In the two-stage digestibility method, OMD values were 71.88, 68.85, 66.99 and 58.52% for parzuk, heliz, meadow grass hay and dried alfalfa hay, respectively insert ignore into journalissuearticles values(P<0.05); The highest OMD was observed in parzuk with two-stage digestibility method, while OMD of heliz and dried meadow grass were similar to that of parzuk, OMD of dried alfalfa was similar to that of dried meadow grass  but less than those of parzuk and heliz insert ignore into journalissuearticles values(P<0.05);.  In in situ experiment, degradability of dried alfalfa, parzuk and heliz were rapid after 4 hours incubation but degradability of meadow grass hay were slow. Dry matter digestibility of meadow grass hay, dried alfalfa hay, parzuk and heliz was 72.45, 76.36, 88.36 and 84.21%, respectively at end of 48 hours incubation period insert ignore into journalissuearticles values(P<0.05);. In conclusion, parzuk and heliz grown at highlands, in case of cultivation, these plants can be alternative forages to other high quality forages such as alfalfa hay.
