Effect of acidosis induction and bacterial probiotic supplementation on rumen bacterial diversity. DGGE profiles of PCR-amplified rrs gene fragments of bacterial communities from the rumen of sheep before (d1 at −1 h) and the last day (d3 at 3 h) of wheat-induced lactic acidosis, corn-induced butyric or beet-pulp propionic subacute acidosis. Each sample is a pool of 4 wethers (from the 4-period Latin square) within the same treatment with C = control without probiotic; P = Propionibacterium P63; Lp + P = L. plantarum + P63; Lr + P = L. rhamnosus + P63. The cluster analysis was based on Dice’s correlation index and the unweighted pair-group method with arithmetic averages (UPGMA). Arrows indicate a specific band for P during lactic acidosis and another one for Lp + P during butyric subacute acidosis.
