Just what the title says. What kinds of grasses and such would you consider to be on good (High Quality) pasture?? When shopping or looking at sites where they ask you to list what your horse eats, I will see, hay, good quality or high quality hay, pasture, good quality or high quality pasture. Soooooooooo, I guess I would like to know what you all think the difference is between regular, good and high quality is. Hay or pasture.
