Totally 24 male sheep aged 13-14 months were used. Sheep were divided into two treatment groups and one conrol group each containing 8 sheep.

The average daily live weight gains in the groups of control, 1 and 2 during experiment were 350.00, 356.25 and 350.00 g, respectively. Total feed dry matter consumptions per kg of live weight gain were found as 5.16, 4.76 and 4.91 kg, respectively. It was also found that baker's yeast had no adverse effects on pH, ammonia - nitrogen and total volatile fatty acid concentrations of rumen fluid.

As a result, it is concluded that baker's yeast can be used safely in the concentrate feeds of male sheep up to 6 %. Keywords : Sheep, yeast, performance, rumen metabolites
