Reproductive management is a primary financial concern of the dairy industry with missed estrus detection one of the major causes of lost income. A rapid enzyme immunoassay (EIA) was developed for on-line measurement of progesterone in bovine milk with a biosensor for detection of estrus. The EIA was developed using covalent binding microtiter wells, monoclonal antibody, horseradish peroxidase, and 3,3',5,5'-tetramethylbenzidine (TMB). The EIA took 8 min and had a dynamic response for progesterone in buffer and milk between 0.2 and 20 ng/ml.
