Performance and microbiota of the digestive tract of Nellore calves supplemented with fungi isolated from bovine rumen.

Background And Aim: In tropical semiarid regions, supplementation with fungi could contribute to rumen modulation, promoting greater production of fibrolytic enzymes and degradation of forage. The objective of this study was to analyze the effect of supplementation with fungi, isolated from the bovine rumen, on the performance and microbiota of the digestive tract of Nellore calves.

Materials And Methods: The experiment was conducted in randomized blocks evaluating eight Nellore calves that were daily supplemented with isolates of and , along with eight calves that were not supplemented.
