Abstract :In this study, four male Kıvırcık yearlings with permanent rumen cannula were used. The animals were fed according to a 4 x 4 Latin square design over 20-day periods insert ignore into journalissuearticles values(15-day adaptation period, 5-day collection period);. The animals were fed four different ration types. Rations I and II consisted of a 70% alfalfa straw and 30% concentrate mixture, while Rations III and IV consisted of a 30% alfalfa straw and 70% concentrate mixture. Rations II and III were supplemented with a daily dose of 4 g of Yea-Sacc1026 insert ignore into journalissuearticles values(Alltech, Nicholasville; 5 x 109 CFU g-1); Saccharomyces cerevisiae live yeast culture. Rumen contents were collected at 0 insert ignore into journalissuearticles values(before feeding);, 3 and 6 h on days 1 and 5 and analyzed for pH, total protozoa counts, total volatile fatty acid insert ignore into journalissuearticles values(TVFA); concentration, ammonia-N insert ignore into journalissuearticles values(NH3-N);, rumen fluid sodium insert ignore into journalissuearticles values(Na+);, potassium insert ignore into journalissuearticles values(K+);, ruminal cellulolytic activity and percentages of different protozoa. The addition of Sc live yeast culture had significant effects insert ignore into journalissuearticles values(P < 0.05); on the percentage of Dasytricha ruminantium insert ignore into journalissuearticles values(before feeding, Ration III 0.31%, Ration IV 1.75%); and Diplodinium spp. insert ignore into journalissuearticles values(before feeding Ration I 4.69%, Ration II 14.62%);. During the same period insert ignore into journalissuearticles values(before feeding); Sc live yeast culture tended to increase protozoa counts insert ignore into journalissuearticles values(P > 0.05);. It was concluded that the rations of high forages and high concentrate supplemented with Sc live yeast culture had no significant effects on ruminal parameters except for the percentage of protozoa.
