Computer Programs

Wondering why our Products are not on FeedXL?

The idea of a computer program being able to check out your feeding program for your horse is a great one.


It CAN be useful when you are feeding a normally functioning horse who is not out on pasture (because the nutrient composition of pasture changes all the time) and who has no health or behavioural issues. However computer programs are not appropriate for the class of horses CHH is helping with, many of whom are ‘not right’ and sometimes have serious health, movement and behavioural issues - where excesses, interactions, different forms of minerals, dynamics and ongoing support, (all explained below) are crucial.

We are often asked so please be advised: here are the reasons why CHH products are not represented on ANY computer feed programme.

Mineral balances are critical to life itself and the computer programme cannot take into account the following aspects:

  1. Interactions, all nutrients require the presence of co-factors (helpers) in order to be able to do their ‘work’. Co-factors might be a specific Vitamin, another mineral or an amino acid. Minerals are also affected by the presence of antagonists – which may be other minerals present in excess which compete for absorption sites or the presence of phytates, nitrates or oxalates all of which effectively ‘rob’ the horse of precious cations in order for them to be excreted.

  2. Excesses are equally as important as Deficiencies. On computer generated reports, nutrients like potassium are often present in significant excess, and this is dismissed ‘as of no concern’. In actual fact it is of serious concern because it competes for absorption with magnesium for instance and interferes with calcium metabolism, just two of the minerals which are at the root of the ‘grass-affected’ issues a great many horses suffer from.

  3. Different forms: Neither can it take into account the difference between inorganic forms of various minerals and the organic forms which are an integral part of our CHH product range.

  4. Dynamics: computer programs cannot take into account the constantly changing seasonal and weather related changes in the horses pasture grass which, when owners have no means of controlling pasture intake cause the need for therapeutic levels/combinations of specific nutrients. The nutrient levels in pasture grass constantly change with the season, weather, fertiliser application or harrowing. Amounts need to be adjusted to suit conditions.

               Pasture grass is the least advised upon aspect of equine nutrition. CHH fully understands this significant proportion of the horse’s diet better than anyone out there

               and our products are formulated accordingly.      

  1. Support: Feeding horses is just as much of an art as riding itself. It is an integral part of ‘horsemanship’ and about developing an acute awareness of changes in the horse and which therapeutic nutrients are required to assist bringing the horse’s metabolism back to normal.  

  2. CHH seeks to help horse owners so they understand how to manage pasture grass and what to feed their horses no matter what the season or the weather, or which issues the horse may have developed. Then they can make the best possible decisions around feed and environment for their horses well-being going forward.


General FAQs

Why did I seldom, if ever, hear of these problems when I started owning horses 40 years ago?

Several factors are involved here:

1. Grazing was not so intensive back then, now there are more people but no more land, in fact there is less land available for grazing than 40 years ago because of urbanization and the takeover of land by vineyards and dairy farms. As Real Estate has increased in value our grazing areas have become smaller and smaller.

This means the vast majority of horse owners don’t have enough land to allow the grass to mature before it is grazed again. This is especially salient because of overstocking – it is just so easy to acquire more horses than you originally intended!

2. Due to this intensification, people tend to fertilise in order to make their small amount of land grow more grass. This alters the chemical composition of the soil and the grass. Usually not in a way that benefits the horse. In other words the mineral balances are thrown completely out of whack and stress is placed on the horse’s adrenal glands and kidneys, which have to deal with it.

3. Most people think of pasture management for horses the same way they would for other livestock, which they are trying to either fatten in the shortest time possible or produce as much milk as possible. Such animals are generally only kept a very short time – 2 – 7ish years before they are killed for meat or culled.
Horses require you to think differently with regard to pasture management in order to keep them calm, healthy and useful well into their 20’s!!! Generally exactly the opposite to how a livestock farmer would think which causes some lively discussions in some households!

4. Rye grasses and clovers are desired by farmers and virtually grow ‘by default’ these days in regions of the globe that enjoy a ‘;cool season’. We met some people a few years ago who used to make their living from growing cocksfoot seed. Unfortunately they went out of business when rye grass came into fashion.
*Interestingly, in Queensland, where clover hardly grows, there is a very low incidence of head flicking.

5. Equine junk food: People did not use commercially prepared hard feeds to the extent they do now. Some of these feeds are promoted to be ‘cool’ or ‘Low GI’, but when you actually take a look at the list of ingredients, you will find all sorts of things such as legumes, extruded rice or other grains, soy, kelp, maize, wheat by-products, molasses (yes even in low GI).

6. Constant harrowing of manure will also change the chemistry of both the soil and the forage because it is applying nitrogen – a little bit is OK but if you are doing it all the time, you will notice that your grass gets darker in colour and affects your horses more and more as time goes on.

Do Horses ‘Self-Medicate’?

Innate Nutritional Wisdom?

Who has it? Most humans don’t. 
Horses are mammals just like humans and they don’t ‘eat selectively for their nutritional needs’ or ‘self-medicate’ from a smorgasbord of plants any more than we do.


More often than not it is best not to let them choose – they will go for what tastes good without realising they are heading for EMS & laminitis (or HS, SIJ, PSSM or any of the ‘grass-affected’ conditions).

Bio-diversity in their diet IS desirable so hay cut from pastures containing a variety of grasses is healthy but allowing uncontrolled access to pasture swards in their vegetative state, which contain more than a scattering of plants like plantain and legumes like clover, is the CAUSE of many of the health problems of modern day horses. Horses need a varied but SPARSE diet rather than a varied and abundant one.

I could not explain it better than Kay Watts from safergrass.org

What about Mineral Licks?

Horses will only consume these to the point they satisfy their craving for salt or their ‘sweet tooth’ if it also contains molasses. Therefore they are an extremely unreliable means of supplying sufficient amounts of other essential minerals like calcium, magnesium, phosphorous, zinc, copper, chromium, selenium and all the Vitamins.

Why is it only one horse in the paddock that seems to be affected and not all of them?

For the same reason that only one person in a household becomes diabetic or gets depressed. Different physiologies, different history of exposure. Usually the other horses are affected in some way. Sometimes it takes longer to show up in some horses.

If my horse is turned out without work should I still feed them according to the Calm Healthy Horses Plan?

Yes. Often we hear about horses that have come back from being turned out without supplementation and they are very 'fresh' or 'out of control'. This cause is due to mineral imbalances and possibly a mycotoxin overload which can take months to get back into balance again. Therefore, it's best not to allow this to happen by continuing the Calm Healthy Horses Plan regardless if they are not being ridden.

Is it related to breed, sex or age?
In all the years since the penny dropped about the effects of grass we have not observed any correlation with breed or age but some conditions like Cushing’s are usually age related.
It boils down to the fact that horses evolved on UNFERTILE country, they were never meant to be confined behind fences eating re-growth grass. They would rarely eat legumes (Clover, Lucerne, Soy etc), grains in any great quantity and they would have access to a far more varied high fibre diet.

My horses are on low (or zero) endophyte rye-grass.
Why is this still a problem?

The endophytes which produce harmful mycotoxins are only one of the undesirable characteristics of rye-grass.Removing the endophytes does nothing to address the high sugar content, the fact that sugar is stored as indigestible fructans, the fact it is high in photodynamic pigments which cause mud-fever & sunburn, and most significantly how it can get so high in potassium and nitrates which I now believe cause most of the problems in our horses.

Are any breeds or genders more susceptible?

While some breeds are more prone to becoming over-weight and EMS, any horse of any breed or gender can be affected...

SIZE has an influence: for example we have observed over the years that ponies and smaller horses have more of a tendency to become EMS and prone to laminitis and the larger horses are more likely to become head-shakers, develop sacro-iliac issues and other neuro-muscular issues and/or exhibit undesirable ‘behaviours’.

Note the word TENDENCY! This is certainly not hard and fast and there are some horses who can exhibit all of the above concurrently.

It is a significant fact that head-flicking is rare in very small ponies

Product FAQ's
What is the general difference between cheaper supplements and the Calm Healthy Horses products?

Cheap supplements are made up of cheap ingredients which is old technology.

Now the true value of high quality ingredients is better understood for vitamins and minerals. Supplements contribute to optimal health and desirable behaviour.

Cheap supplements have only bare minimum levels, or omit completely, ingredients such as MSM (organic sulphur), Inositol, biotin and chromium.

Cheap supplements don't contain organic forms of minerals which can be many times more bio-available and useful to the horse, than inorganic forms.

We have anecdotal evidence of this many times over; science is usually five to ten years behind anecdotal evidence. Minerals such as selenium are much safer and less likely to cause toxicity when present in their organic form. Iron when present in its inorganic form interferes with the absorption of several other minerals. 

Demineralisation of the horse, especially the skeleton, is not something you see from the outside. Often the first sign is the onset of degenerative diseases before the horse is 20.

Everyone wants a calm, healthy horse that will give you many hours of safe riding and live a long, useful life. By feeding the best vitamin and minerals, you will find less need for joint/hoof and coat supplement. A blend of top quality, well balanced vitamins and minerals feeds the whole horse and you may find less need for other treatments. You will spend less time worrying and more time riding!

Aren’t liquid formulations absorbed better than powders?

Absolutely not, there is no difference in absorbability at all. The fact is that liquid formulations usually involve a compromise of ingredients because many of the best nutrients are not water-soluble so have to be left out.
They also mean you are paying for water which is heavy, to be freighted around.

Can horses be allergic to your Vits & Mins?

All the ingredients except the apple flavouring are naturally occurring nutrients which are necessary for life. There could be a remote possibility that a horse might be allergic to the apple.

Diet VS Movement

Does Diet Trump Movement?

This is a curly one which will spark some healthy debate but in my experience I believe yes overall, diet trumps movement. Obviously getting both right for our horses is our goal.

Compare lifestyles of horses living in NZ where most horses are turned out on green grass all their lives and get far more movement on a daily basis yet most are finished their useful life before they are 20!

Compare this to California on Boarding Ranches where they live in pens on hay with turnout for an hour only 2-3 times a week or Europe where horses are stabled more of the time than here in NZ, and seem to averagely have a longer, useful life well into their 20’s & 30’s!

A high fibre diet is one of the most important ingredients for optimal health and longevity in horses. Conversely a lifetime of a chronically high potassium/low salt diet is extremely detrimental.

Sometimes there are occasions when a choice needs to be made for the short term. When an unsuitable diet has compromised the horses metabolism to the point he is ‘metabolic’ or ‘insulin resistant, it is absolutely necessary to confine him off the grass rather than let him suffer the agony of laminitis.

If you have a horse who is too fat but not yet ‘metabolic’, upping  exercise is the best thing you can do but horses that are ‘metabolic’ can tip over into laminitis at the slightest change in the grass and it is safer and more prudent to get them off before it is too late!

If your only choice of grazing is fertilized rye-grass and clover, your horse is far better off confined in a yard on hay than turning into a dangerous, raving lunatic.

If your horse is sane and sensible because he is being fed correctly then you are going to be enjoying RIDING him!


What role does selenium play in the overall scheme of things?

Selenium is vital in conjunction with Vit E to prevent tying up in performance horses and contributes to muscle strength and stamina.

Selenium is also one of the major antioxidants (along with Vits A, C and E). Other products containing Selenium should not be fed at the same time as Premium New-Zealand-Horse Minerals. Neither should fertiliser containing Selenised prills be applied to paddocks.

The next time you have a vet check, have the blood levels tested for Selenium (basic test only), then again 12 months later. You can compare the levels and check to see they are still normal.

More General FAQs

My horse does well on what I am currently feeding him. If I change will he keep weight on?

You will be pleasantly surprised how little horses need to retain good body weight once their nutritional requirements are correctly met.
The Calm Healthy Horses Plan offers an economical and healthy way of feeding your horses without affecting a healthy body weight.

I don’t have much Rye Grass, why am I still having problems?

In the early days, we too thought that all we had to do was eliminated the all the rye grass and clover and replace with ‘horse-friendly’ grasses and all our problems would be over. However, it soon transpired that there is a lot more to it.

NB: You will never eliminate ALL the rye-grass as there are millions of seeds in the ground. However if it is growing as part of a mixture of grasses it won’t cause problems, it is more problematic when it is grown as a ‘mono-culture’ or with clover and that is all they have to eat.

Sowing more horse-friendly (usually natives or grasses NOT ‘improved’ or selected for high production) grass species is absolutely a step in the right direction but how you manage these grasses is crucial to keeping your horses calm and healthy on it.

Any grass that is over grazed or in growth mode (Short and green) is minerally unbalanced because the only concern of the grass is to recover so it can produce seed and reproduce.

Rye grass and other high production grasses have been selected for their rapid growth, high nutrient density including sugars and sometimes endophyte properties – this makes them more unsuitable for horses than other species.

You will often be told about rye-grass: Oh it is OK for horses, it is ‘low endophyte’ or ‘endophyte free’. If endophyte fungi were the only problem with rye-grass then that may be true but endophytes are just about the least of the problems with rye-grass.

Mineral imbalances top the list, followed by NSC content, the fact it stores sugars as indigestible fructans, photodynamic pigments which contribute to photosensitization of the nose and white areas of skin and whether it harbours endophytes which potentially produce harmful myco-toxins ( if it is an endophyte strain.)

Hence other names for rye-grass are “Founder Fodder’ or ‘Disaster Pasture’!

A healthy horse can handle some rye grass as part of the pasture mix with the help of suitable nutrition as recommended on the website. It is not very often though, that clover does not cause problems of some description or other, especially if the horses are not well nourished.

Reintroducing Grass

When we say that horses need to come completely off grass, we usually mean it as a temporary measure. Usually 1-3 months, with some head-shaking horses and founder cases taking longer.

It only sounds drastic until you wrap your head around it. It is, more often than not, the fastest way to get good results.

Only when the horse has come back to his normal self can he be SLOWLY reintroduced to more ‘suitable grass’. Hopefully over the time the horse has been off the grass has given it time to grow long and more mature. Then you can start by giving them access for ten minutes am & pm and increase the time accordingly.

Some people forget that horses can eat a colossal amount of grass in a short time, especially if they have not had any for awhile! If the horses has had laminitis for instance you have to be really careful.

Whether the grass is ‘suitable’ or not depends on what species it is and the stage of growth, time of the year and the weather. It rarely works to put them back out on pasture with ANY clover for instance so while they are in lock-up is a good time to eliminate it.

Mature grass is ideal .

Be observant for the return of any signs of a relapse and if there is any doubt then take them off the grass for a bit longer.

When is it OK to use Bute ?

Phenylbutazone, usually referred to as ‘Bute’ is a ‘Non-steroidal anti-inflammatory drug’ which is appropriate to relieve mild pain. The extreme pain of acute laminitis or serious wounds may require much stronger and more effective pain relief from your veterinarian.

People have a somewhat unwarranted aversion to using ‘Bute’ but there are occasions when it is the humane thing to do on a SHORT term basis. It can provide much needed pain relief so long as you follow the vet’s instructions. (Long term over-use of ‘Bute’ can lead to serious problems such as ulcers, blood abnormalities and kidney problems).

Of course it is inappropriate, unethical and unfair on any horse to use ‘Bute’ to mask mild pain long term in order to be able to work or sell the horse or for the purpose of being able to compete.

Most veterinarians, and rightfully so, will not give you ‘Bute’ without a visit first. This is to ensure that the horse’s condition isn’t a lot worse than what you may have thought and that ‘Bute’ would be suitable pain relief.
It’s important to remember that ‘Bute’ does not ‘cure’ the problem. It reduces inflammation and therefore pain ensuring the horse is more comfortable when suffering from various ailments.

It usually results in the horse ‘perking up’ as pain relief kicks in. The horse becoming more depressed, or off its feed would be cause for concern.
‘Bute’ is not appropriate for any form of ‘colic’ which is an emergency when the vet should be called urgently anyway.
