Stability is the first criterion of probiotic after its scientific identification. For rabbit, probiotic must resist for the enzyme of digestive tract and the high temperature during diet pelleting. The aim of this study is to evaluate yeast S. cerevisiae SC 47 stability in rabbit diet. Three diets were formulated. Diets DF deficiency fibres group (21%NDF) is constituted by diet DF0, DF1 and DF5. Zero, 1 and 5 g of yeast S. cerevisiae SC 47 per kg were used respectively in diet DF0, DF1 and DF5. Diet C (37%NDF), 0, 1 and 5 g of yeast S. cerevisiae SC 47 per kg were used respectively in diet C0, C1 and C5. Diets group T (39%NDF), 0, 1 and 5 g of yeast S. cerevisiae SC 47 per kg were used respectively in diet T0, T1 and T5 formulation. One gram of yeast S. cerevisiae SC 47 in diet is equal to 10 10CFU. Results show that pelleting temperature was increased linearly with fibres concentration in diet Θf(°C) = 7.3 (±5.2)+0.8(±0.2)×NDF(%), P<0.1, R 2=51%). When pelleting temperature increases, 1 log (CFU/g) of yeast S. cerevisiae SC 47 in diets is destroyed from 21%NDF to 37%NDF. However, with 39%NDF in diet, 3 and 2 log (CFU/g) of yeast S. cerevisiae SC 47 were lost. Yeast S. cerevisiae SC 47 can be considered to be stable to pressure and temperature variation during the pelleting. © EuroJournals Publishing, Inc. 2012.
