If you answered *Yes* to any of the above questions and *No* to the last question, you'll want to read this.
It has been shown that excess iron in the horse's diet can cause on-going laminitis.
Laminitis -- that dreaded hoof condition that no owner wants to hear with respect to his or her horse!
Iron comes through many factors in a horse's diet ... from grazing to hay to grain being fed and supplements being fed. Iron is in nearly everything the horse consumes– grass, hay, dirt, water, most commercial feeds and the majority of vitamin/ mineral supplements.
One of the most influential factors of excess iron in the horse's diet can be from the water he drinks.
The 'safe' intake of iron for the average sized horse is 400 mg of iron per day for a 500 kg (1,100 pound) adult horse on maintenance feed. Anything over that and your horse is going to run into issues with the hooves, the blood, the thyroid (insulin resistance), immune system, red blood cells and more.
While soaking hay helps to remove some of the iron in the hay, if the water contains high levels of iron, one is totally defeating the purpose of soaking the hay and may be actually adding iron to the horse's diet. (The National Research Council, part of the U.S. National Institutes of Health, provides a list of “Nutrient Requirements of Horses.” The reference guide is available online.)
Excess iron has the negative effect on the uptake of copper and zinc – two minerals that are often already deficient in horses’ diets – as well as manganese. Dr. Eleanor Kellon recommends an iron: copper: zinc: manganese ratio somewhere between 10:1:3: 3 to 4:1:3:3, with the latter ratio being recommended for Insulin Resistant (IR) horses.
So given this information I'm sure you are wondering just HOW to eliminate or reduce the amount of iron in your horse's diet.
Check labels to see the amounts of iron in the feed or supplement. Get an analysis done of the hay you are feeding. You also might test the soil of your grazing fields ... grasses grown on acidic soils are more likely to be high in iron. Lime added to the fields will help to reduce the iron levels in the ground.
One of the simplest thing you can do to reduce the iron in your horse's diet is to filter your water.
There are a few good, inexpensive filters that can be attached right to the spigot head to which to attach your hose, at the end or your hose or you can get a filtration system for your water pump.
I hope this short blurb will help you ferret out the reasons you may be facing hoof, whole health and behavioral issues with your horse.
