An observational study was conducted in 79 mature Holstein cows from 28 dairy farms selected from Ontario Veterinary College, Ruminant Field Service clients that participated in a monthly herd health program. The objectives were to describe the prevalence of hypocalcemia, to evaluate the history and the physical examination findings to predict hypocalcemia and to evaluate the power and the positive predictive value of the Withers Pinch Reaction (WPR) test as a new screening test.
