Comparative evaluation of the therapeutic efficacy of rumen buffers and direct fed microbials (DFM) in sub-acute ruminal acidosis in dairy cows

Sub-acute ruminal acidosis (SARA) in dairy cattle is a disorder of fermentation caused by the ingestion large amounts concentrates with inadequate fibre. The condition characterized sustained and marked decrease rumen liquor pH ≤5.5 for at least three hours each day. Rumen buffers direct fed microbials (DFM) are dietary supplements that had been used management SARA. samples cows from organized farms households Wayanad district which were risk SARA collected rumenocentesis estimation. Blood positive subjected to haemato-biochemical evaluations. Three different therapeutic protocols involving oral administration sodium bicarbonate, Lithothamnium calcareum extracts as mixture Saccharomyces cerevisiae Aspergillus oryzae microbial compared 14 days efficacy treatment was evaluated improvement after period. buffer like bicarbonate found be more efficient than DFMs improving values
