Below is some general information about grazing on these types, and colic is probably not the biggest concern. Founder is a concern depending on the following factors:
* Is the horse receiving supplemental feeding to help create some gut fill to prevent the horse from gorging on pasture?
* What is the length of time the horse is turned out and allowed to graze?

Wheat is an excellent cool-season annual grass that can be used for winter grazing. It is not a typical horse pasture species, but as with other cereal grains such as rye, barley, and oats, these forage species can be planted on an annual basis to help extend the grazing period. As with all forage crops, a major requirement for effective use of grazing oats for horses is proper management. Potential extended periods of grazing are in late fall, early winter, and early spring when the primary forage species are dormant. In return, this could result in a 12-month grazing program if pastures are managed intensively. Oats and other cereal grains are more cold-weather tolerant and can therefore survive and grow in colder temperatures. They can be planted as a single stand or can be overseeded into an established pasture. Horses grazing cereal grains can be more prone to colic, laminitis, and founder, so it is important to limit their exposure, and the horse(s) must be monitored closely. In addition, if this species is planted as a single plot or pasture, horses should not be turned out when the soil is wet. If they are turned out when it is wet, there is high potential for the horse(s) to tear up the pasture very easily because no sod is formed. So with proper management of both the crop and the horses, oats can be an effective part of a grazing program for horses.
