This large scale, double-blinded, randomised controlled field trial was designed to test the effect of augmenting the standard treatment of clinical mastitis with a non-steroidal anti-inflammatory treatment (meloxicam). The null hypothesis was that cows treated with a parenteral antibiotic (penethamate hydriodide) in combination with meloxicam would have no differences in somatic cell count (SCC), milk yield, clinical outcomes or culling rate compared to those cows treated with penethamate alone.
