Feed companies, equine nutritionists, vets and feed testing companies generally assume that all horses have the same mineral requirements. Just observe the many mineral/vitamin mixes on the market at present. The problem with this assumption is that soil type and water source are not taken into consideration when recommending supplements. For example, many areas of Australia contain soils high in iron so iron in a supplement is rarely required and toxicities are common.

Hay and pasture testing must be done at each season to get accurate results due to variables in seasonal rainfall fluctuations which affect the mineral composition of the soil.
Bore, river and spring water often contain high concentrations of minerals and if you guess when adding a supplement to the feed, you are often inadvertently overdosing your horse on minerals by not taking into account the mineral levels in the water supply.
Yearlings, geldings, stallions and mares have different mineral requirements as do horses in light work compared to those in heavy work.
Once I have been advised of all the supplements and feeds your horse currently receives, taken into consideration the water and soil type then compared that to the analysed hair tissue sample, I will determine which minerals your horse actually requires. Appropriate raw minerals will be recommended that are readily available from good produce /feed stores at much cheaper prices than commercial brands or from equine nutritionists.

Individual raw minerals are far more bioavailable than branded minerals mixes which often contain minerals that your horse does not actually require, are of poor quality, or are synthetic forms or already has in excess. HTMA determines the dosages your horse requires so that deficiencies and excess of minerals can be avoided. Deficiencies and excesses of minerals cause health and behavioural problems in your horse.

THE HORSE FEED INDUSTRY IS UNREGULATED. There is no independent body to audit premixed feeds/supplements  Most of the commercial mineral mixes and feeds fortified with mineral/vitamins just simply do not deliver what they claim – laboratory reports of hair mineral tested horses prove this. Very few feed companies, equine nutritionists selling products or commercial mineral companies will not subject their products to independent clinical trials. HTMA can demonstrate the efficacy of supplementing with the appropriate raw minerals that your horse actually requires.
Take control of feeding your horse what he/she actually requires bearing in mind that most commercial mixes/feeds on the market may not be suitable for your individual horse. A one size all approach to feeding a horse is impossible and will not deliver the correct amount of nutrients for your horse living on your property.
