1 st WorkshopXIII International Feed Technology Symposiumfeed mixtures the total count of bacteria decreased from 400,000/g to 20,000/g, and totalcount of molds from 12,000/g to 300/g, respectively. The simillar results were obtainedby Lević et al. [9] – pelleting of the calf fodder was shown to reduce the total count ofbacteria by the factor of 15, and the total count of molds by the factor of 8.25. Adamovićet al. [1] observed also positive influence of the pelleting on the improvement ofmicrobiological properties of feed mixtures with bentonite supplement.Table 2.
