Abstract
Subacute ruminal acidosis (SARA) is defined as periods of moderately depressed ruminal pH, is one of the most common chronic digestive disorders, especially in well-managed dairy herds. The study was conducted at Large Animal Medicine-Out patient Unit of Madras Veterinary College Teaching Hospital to document clinical, haemato-biochemical, rumen fluid, milk and ultrasonographic changes and to assess the efficacy of treatment protocols in the management of SARA in dairy cattle. In the study, dairy cows with the history of reduced dry matter intake, drop in milk yield and diarrhoea were subjected to detailed physical examination, haemato-biochemical, rumen fluid analysis, serum haptoglobin estimation and ultrasonographic evaluation. Twenty two cows were found to have SARA based on rumen liquor pH ranging from 5.4-6.0. Twenty cows were selected and randomly subjected for treatment trial with oral Sodium bicarbonate at the dose rate of 250gms/ cow/ day and Saccharomyces cerevisiae at the dose rate of 25×109 CFU/ cow/ day for seven consecutive days.
