การวินิจฉัยและการรักษาโรค Subacute Ruminal Acidosis (SARA) ในโคนม

Abstract

Subacute ruminal acidosis (SARA) is a common disease in well-managed, high milk yielding in dairy herds. Monitoring and diagnosing are very sensitive to do its routine for dairy herds. SARA may be affected to reduce milk production and milk fat in early lactation or mid lactation cows. Diagnostic tools are clinical sign outcome or ruminal pH (≥ 5.5) and faecal parameters: faecal sieing and faecal lipopolysaccharide (LPS). Rumenocentesis is a good practice and only recommend method for SARA diagnosis although stomach tube use is easy but its value data is not correct. The treatment and prevention of SARA is depending on feeding and management base following to each situation of dairy herds in order to reduce rumen acidosis load such as used S. bovis vaccine or added sodium bicarbonate.
