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