Below is a list of natural horse vitamins and minerals with a short description of ways in which they can be beneficial to your horse.
Vitamin C (Ascorbic Acid)
Used to fight infection and help with snake bites.
Available forms
Powdered and injectable.
Dosage
As a preventative: 20g twice a day for an adult horse
With an active illness or infection: 20g four times a day for an adult horse.
Useful in horses and ponies with cresty necks and fat deposits as the magnesium helps break them down. In a normal diet the ratio of calcium to magnesium should be 2:1. Horses can suffer from a magnesium deficiency if the diet contains too much calcium in relation to the magnesium.
Available forms
Organic or chelated (those found in foods, such as magnesium gluconate and magnesium asparatate) and inorganic
(found in the soil, such as magnesium sulfate and magnesium oxide). The organic forms are more readily absorbed.
Human feed grade quality magnesium is available from MadBarn or often from your feed store.
Dosage
Start with approx 3 grams per day for a small pony and up to 12 grams for a large/heavy horse
for the first three weeks when you should see signs of changes
in the fat deposits. Then the dose can be halved for 6 - 8 weeks and
once the fat has normalized then a maintenance dose should be calculated
based on hay/grass analysis.
Horses need to have salt available to them at all times. In the summer they need it to replace the salt lost through sweating and in winter they need it to ensure they drink enough water to prevent colic. Loose salt is best as it is hard for the horse to get enough salt from a salt block and salt blocks often contain other minerals that are detrimental to the horse when consumed in the large quantities needed to get the correct dosage of salt. Iodine is also very important for the horse so I use iodized table salt directly into their feed bucket - that way I know they are getting enough salt. Also by providing 2 oz of iodized salt you will ensure that the daily requirement for iodine is met.
Dosage
At least 2 oz a day in summer (can be up to 3-4 oz if working hard in hot weather) and at least 1 oz a day in winter.
