Ruminal acidosis and its definition—A critical review

This comprehensive review redefines ruminal acidosis (SARA) diagnosis in dairy cattle, looking beyond rumen pH to embrace a multifactorial approach. It introduces and supports the Bramley Acidosis Model (BAM), integrating volatile fatty acids and ammonia for better disease characterization. With historical context, biological validation, and future sensor technologies, the article offers a forward-looking framework for detecting and managing SARA in commercial herds.
