ABSTRACT: The objectives of this study was to diagnose and study the effects of subacute ruminal acidosis (SARA) on ruminal fluid and fecal compositions in dairy cows.SARA was diagnosed by measuring pH of rumen fluid collected by rumenocentesis four hours after feeding. Out of 100 dairy cows examined for SARA based on rumen fluid pH, it was noticed that 20 dairy cows had rumen fluid pH ranging from 5.2 to 5.6 for more than 180 minutes/day and were considered as positive for SARA and 80 cows had ruminal fluid pH more than 6.2 and were considered as negative for SARA. In the present study 20 SARA......
