Wheat has an inverted phosphorus to calcium ratio and this can cause reabsorbing of the calcium already present in the horses bones due to the high amount of phosphorus in the feed blocking the absorption of new calcium. This can lead to weakened bones, which could lead to bone breakage and the horse may need to be put down. If wheat is fed you need to supplement the diet with added calcium to balance it out and make it safe to eat.
