The effect of feeding different levels of yeast Saccharomyces cerevisiae on tibial bone characteristics of the New Zealand rabbits was studied. An experiment of 85 days duration was conducted with male 5-6 weeks old rabbits. There were 3 dietary treatments each consisting of 7 rabbits in each. The treatments were containing 0 (control), 2 and 4 g kg(-1) yeast (Saccharomyces cerevisiae) in their diet, respectively. At the end of the experiment the right tibia of rabbits were dissected from the surrounding tissues and used for bone force and stress measurements. Results show that there is no effect of feeding with different level of Saccharomyces cerevisiae yeast on body weight, tibia weight and length, bone force and stress values of tibia of the rabbits.
