A PROCESS FOR MAKING DRY GRANULAR COMPOSITIONS CONTAINING DESICCATED VIABLE RUMEN ORGANISMS FOR LIVESTOCK FEEDING WHICH COMPRISES ADMIXING AN AQUEOUS SUSPENSION OF RUMEN ORGANISMS WITH SUGAR, ABSORBING THE LIQUID MIXTURE ON A SOLID CARRIER SELECTED FROM THE GROUP CONSISTING OF COMMINUTED FIBROUS CELLULOSE. MILK SOLIDS AND SOIL TO FORM A GRANULAR MIXTURE, SAID MIXING OPERATIONS BEING CARRIED OUT IN THE ABSENCE OF AIR, DRYING SAID GRANULES UNDER VACUUM, INTRODUCING AN INERT GAS WHEREBY THE PORES AND INTERSTICES WITHIN SAID GRANULES ARE FILLED WITH SAID GAS, AND THEN COATING SAID GRANULES IN THE PRESENCE OF THE INERT GAS WITH A COMPOSITION WHICH FORMS A SURFACE FILM SUBSTANTIALLY IMPERVIOUS TO THE ATMOSPHERE.
