Abstract

Urine ammonium concentration ([NH4+]) provides a clinically useful indicator of the magnitude of nutritionally induced systemic acidification in dairy cattle when urine pH < 6.1. The objective of this study was to evaluate the analytical performance of a low-cost point-of-care colorimetric test in measuring urine [NH4+] in dairy cattle consuming an acidogenic ration.
