The objective of this study was to evaluate ruminal fungi as potential probiotics in association with high-grain diets in carcass performance and yield, and acidosis in Santa Inês/Dorper lambs. A 4x2 factorial was adopted in CRD, with two processes (ground or whole grain) and four inoculants (without inoculants, with Rhizomucor spp., With Aspergillus terreus and with a mixture of fungi). Eight stalls with five lambs/stall were used for 75 days. Diets with 85 % corn plus 15 % nucleus are provided twice a day, with inoculants sprayed at the time of food handling. Five collections of ingredients of the ingredients of the diets, diets and leftovers were carried out during the experiment. The animals were weighed every two weeks. At the end of the experiment, on slaughter, the carcass index of five animals/treatment was calculated. Data were submitted to ANOVA and the data averages compared by the Tukey test at 5 %. There was no interaction between the processing and probiotic factors for the performance variables (P > 0.05), just as there was no effect of the addition of probiotics on the performance of the sheep fed with the different treatments (P > 0.05). Higher consumption of DM, MM, EE, NDF and NFC was observed for animals fed with whole grain corn (MGI) (P < 0.05). There was no significant difference (P > 0.05) for the consumption of OM, CP, MDG, intake and for food efficiency. The increase in the concentration of fungi and the association of factors in the diet did not prove to be effective.
