I am new to the forum and am really enjoying it. I was wondering if you could help us with a question regarding winter pasture turnout. We bought a 5 acre farm this spring, 4 of which are grass pasture. The pasture is in good condition, however, I have heard pros and cons on leaving horses out on it during the winter. Is it harmful to the horses to be nibbling on semi-frost grass? Also is it harmful for the grass to have the horses on it all winter. We have 3 horses, who are stabled at night. They are turned out on the pasture from 7:00 AM and brought in at 6:00 PM. The pasture is not their only feed source, more for turnout. They get hay AM PM and grain in their stalls at night.Thanks for any input.
