    The aim of this research was to investigate the effect of supplementation of Saccharomyces cerevisiae viable yeast culture (Yea-Sacc1026,5x109 organisms/g) into diets having different forage: concentrate ratio on the in vitro rumen dry matter, organic matter and neutral detergent fibre digestibilities. In this research, four cannulated sheep were used in 4x4 latin square design and fed on 70 % alfalfa hay + 30 % concentrate (Diet I), 70 % alfalfa hay + 30 % concentrate + 4 g Yea-Sacc1026 (Diet II), 30 % alfalfa hay + 70 % concentrate + 4 g Yea-Sacc1026 (Diet III) and 30 % alfalfa hay + 70 % concentrate (Diet IV) respectively. The duration of each experimental period was 20 days. On the 20th day, rumen digesta was collected from sheep for in vitro incubation 2 h after morning feeding. At the end of experiment, supplementation of yeast culture on high forage ration significantly increased the in vitro rumen dry matter, organic matter and neutral detergent fibre digestibilities (P<0,001), while did not affect on high concentrate ration.
