Horses NEED hay.

Horses need longstemmed forage. They can’t live on pelleted or grain rations alone, or they will develop ulcers. They need feed in their belly at least 12 hours of every day.

If the milled alfalfa and peanut hay had longstems- at least 2-3 inches long, it would be a good base for the diet. I’d give each horse 1 pound of hay for every 100 lbs of weight, twice daily. So a 1000 pound horse should eat 10 pounds morning and night.

If they were my horses I would mix one part bran, 2 parts crushed corn and 2 parts alfalfa pellets and enough molasses to make it stick together.Keep offering free choice salt and water.

Protein. This builds up cells and bones and helps with healing, growth, and repair after illness or injury.

Fiber. This keeps digestion working properly.

Fats. These help keep a horse warm and provide extra energy.

Vitamins and Minerals. These keep the body healthy and strong

types of fiber
Grass is the best and most natural food for your horse. If your grass is of good quality, it will provide a complete, balanced diet during spring and summer. Autumn and winter may reap a poor selection of grass, so hay must be fed.

Hay is essentially grass cut and dried in early summer and stored for horse feed during winter or when they are mostly stabled. You should only feed hay that is crisp, sweet smelling, and containing a good mixture of nutritious grasses. Never feed hay that is dusty, moldy, yellow, or full of weeds. The two types of hay are seed hay, which has been grown specially, and meadow hay, which is softer, finer, and cut off the ordinary pasture.

Chaff is usually straw or a mix of hay and straw that has been chopped up and often covered with molasses. Alfalfa chaff is a very nutritious clover-like plant high in calcium. Feeding chaff is an excellent way of adding fiber to your horse’s diet.

Haylage is hay that has been treated and sealed into bags when half-dry. It is dust-free and therefore a good choice for horses sensitive to the dust and spores in ordinary hay. It is very rich, so be sure to feed sparingly

Hard feeds

Pellets / cubes are a balanced mixture of traditional foodstuffs, crushed or pressed into pellets. This is probably the best (and most economical) hard feed for most riding horses. With water and hay or grass, they provide all the nutrition your pony needs. Remember, don’t add anything to a diet of pellets except chaff, apples, or carrots, or you will ruin the formula. There are many different kinds of pellets, so be sure to buy the correct kind. There are pellets for ponies doing little work and pellets for competition horses, brood mares, and foals.

Coarse mix is a ready-to-go mix like pellets, but bought in muesli form. This is great for horses for the same reasons as pellets (see above).

Oats are bought crushed, rolled, or bruised so they are easily digested. These are good for horses doing a lot of work. Watch out! These are guaranteed to wake up the laziest pony. Oats must be fed with a calcium-rich food to maintain the right balance of calcium and phosphorous.

Barley is bought flaked, micronized, or extruded (forms of cooking). Whole barley can be boiled into a mash. This type of feed provides energy for regularly working horses, and is also good for warmth and putting on weight. Note that barley should not make up more than one third of your horse’s total feeding.

Flaked corn is used for hard-working ponies, in small amounts. Feed sparingly, as this is high in energy as well as phosphorous.

Broad bran is traditionally given as a mash for resting, sick, or old horses. When prepared in this way, it also works as a laxative. This can cause a calcium deficiency. Adding chaff to the feed is a better source of fiber.

Dried sugar beets come as shreds or pellets, with added molasses and they are good for adding fiber to hard feeds. Horses like their taste, and they are high in energy and calcium. Note that these must be soaked in water for at least twelve hours before feeding. Do not keep soaked beets for more than 48 hours because the mixture will ferment. Don’t confuse beet pellets with similar looking ordinary horse pellets.

Bran (wheat bran ), Hormony Chop ( Corn Bran ) , Molasses Meal, Sunflower oil Cake ( it’s a milled form of sunflower simmilar to Soya meal ) Crushed Corn or in meal form, Milled Alfalfa, Milled Peanut hay, Alfalfa pellets, 10% complete horse concerntrate pellets – not always availible!

I give herbs and mineral licks to all my horses.
