Abstract

Dry cows and springing heifers from twenty-five farms near Guelph, Ontario, Canada were enrolled in a large double blinded and randomized clinical trial designed to evaluate the impact of monensin on periparturient disease and milk production. A total of 503 cows were given monensin controlled release capsules and 507 animals were administered placebo capsules three weeks prior to expected calving date.
