Fresh pasture has plenty of vitamins, many of which are subsequently eliminated during hay production because they are so sensitive to the environment — heat, air, sunlight, humidity, and rain can start destroying vitamins within hours after grass is cut. That’s why an exclusively-hay diet will leave gaping holes in your horse’s nutrient intake. Grazing on pasture will certainly make a difference, but even these horses will need supplementation to fill in gaps that are likely to exist if the grass is of poor quality, over-grazed, or suffers from heat or drought stress.

Below are a few resources on specific vitamins. For a more complete discussion, see Chapter 6 in Feed Your Horse Like A Horse.
