Abstract: The invention pertains to the field of probiotic compositions useful for human and/or animal food and health. The invention particularly relates to compositions containing stable probiotic microorganisms during the production of tablets or granules for final use. The works of the applicant of the present invention show that the mortality of probiotic microorganisms during granulation is closely linked with granulation operating conditions and with the characteristics of the selected microorganisms. Said works have led to the establishment of a mathematical expression for defining both the characteristics of the yeast as well as the parameters of the method so that the microorganism losses after granulation are lower than 1 log CFU/g of granulated food.

Abstract: The present invention relates to a probiotic composition or premix comprising live or regeneratable probiotic microorganisms, yeast walls and/or deactivated yeasts, and, optionally a nutritional supplement comprising in particular vitamins and/or trace elements and/or amino acids and/or other additives intended for animal nutrition. It also relates to granules comprising said composition and intended for animal nutrition, and also to a method for preparing said granules.
