In this study, the effect of grazing on green growing pasture and concentrate supplementation on nutrient content of the pasture and liveweight gain, rumen pH, total volative fatty acids and amonium nitrogen concentration in Morkaraman and Tuj lambs were determined. Dry matter, crude protein and crude fiber contents of pasture were 23.08-45-34%; 17.18-6.72%; 23.78-36.45% with respect to vegetation period. Tehere were no significant effect grazing and supplementation on liveweight and liveweight gain between the two breeds. Grazing groups liveweight was gained 14.42 kg and supplementation groups were 17.40 kg in the experimental period and this total liveweight gain were significant between two groups. While supplementation groups were less pH value more than grazing groups, there were no differences in TVFA and NH3-N between grazing or supplementation groups
