The use of monensin premix in dairy cows: Simple and essential steps for ensuring its proper use. Dietary monensin, containing monensin sodium as active ingredient, is frequently used on dairy farms in Canada. Although the use of monensin is safe, some overdose situations have been reported following consumption of higher than recommended doses. A regular monitoring of bulk tank milk fat percentage should be performed to ensure quick detection of a potential overdose situation. Diarrhea and sudden drop in dry matter intake are other potential clinical signs of monensin overdose.
