About $18.50 per 50 lb bag. I have look every where for a good mineral and this one was a little different from the last one. I put out 5 lb coffee can full daily and sometimes skip a day. They will have most of it cleaned up daily. That's for 12 grown cows and 3 caves. It equate to about 5 oz per head but I know some will eat more than others. I think the label says 4 oz per head daily. I think I'll try this one thru the winter and it it shows up in the cattle, I'll stick with it for a while. They will probably eat about 3 bags a month, about $55.50 monthly. I like the wind and rain but don't like the $55 a 50 pound bag. When I was using it I really didn't see much change in the cows. May not kept them on it long enough. plus Tractor Supply don't always have it in stock.
