Back in the days when I was instructing
full time, I used to think ‘training’ could solve almost
Then I realised you couldn’t train a horse effectively if
it was in pain from it’s feet, saddle fit or the bit, or any
other kind of physical pain for that matter, usually resulting from
long term damage to the body from one of the above, or as I've now
recently discovered - chronic mineral imbalance.
Now I have come to realise that even more issues are the result
of the grass we allow our horses to eat, along with imbalances or
lack of certain minerals and vitamins. Or the massive imbalance
that rapidly growing grass can cause in Autumn and Spring, it has
been widely reconised in cattle as grass tetany but until recently
it has not been recognised or proven in horses.
So many people struggle with horses that are over-excitable, nervous,
jumpy, suffer separation anxiety, have a sour attitude, can’t
move forward, and are generally uncontrollable, and think that better
training will fix the horse.
Sure, some horses can be ‘trained into submission’ with
various techniques but that just causes the horse to shut down eventually
– it doesn’t solve the cause of the problem.
Are these behavioural issues? What has changed in the horse’s
First, its best to check that pain isn’t causing a problem,
then look at any changes made to their diet:
1/ Have they moved to a new paddock
2/ Is the grass short and under stress?
3/ Been fed something different such as ryegrass or clover hay?
4/ Their living situation, have they been removed from the herd,
or lost a herd member?
5/ Has a particular grass such as Rye Grass, Clover, Paspalum, Couch
Grass, Phalaris (Blue Canary grass), Cat's ear flat weed (looks
like dandelion), Tall Fescue in reasonable amounts in the paddock?
6/ Has a weed increased, such as Cape weed, Patersons cures, St
John's Wart, Fire weed, Poison buttercup, or Deadly night shade?
7/ Have you changed or cut out the vitamin and mineral supplement
you feed in the past 2-3 months?
8/ Or have you made changes to the equipment you use (new saddle,
bridle, pad, girth etc?).
Any or all of these can affect a horse’s behaviour.
So if you’ve changed your horse’s diet, then that could
be the cause – especially if you’ve moved them to a
fresh pasture, and especially if that pasture has grass that is
So what is toxic grass?
Any grass under stress or climatic conditions such as those of early
spring and autumn, especially in drought-breaking rains or cool,
cloudy, wet weather, including frosts, is subject to acute spikes
of potassium and nitrate at the same time becoming low in sodium.
This is exacerbated by nitrogenous fertilisers.
The potassium nitrate ingested is highly toxic and the body eliminates
it by latching on to calcium and magnesium so is excreted with them.
Hence the necessity to feed adequate calcium/magnesium and sodium
while not adding to the potassium load with lucerne/molasses, many
herbs/garlic/high protein feeds/supplements containing potassium.
Grass that is too high in sugars (NSC’s – Non Structural
Carbohydrates) such as rye grass, or has oxalates (binds up calcium)
such as Kikuyu, Setaria, Buffel, Green Panic, Pangola, Para Grass,
Guinea Grass, Signal Grass and Purple Pigeon grass, or has mycotoxins
that are produced by endophytes in grasses such as rye and paspalum,
or has moulds/pollens or is drought stressed, is toxic.
It's also a good idea to find out from your local Department of
Primary Industries what weeds are prevalent in your area that could
be dangerous to horses.
Grass is a huge topic and I recommend you start by reading the article
further down this page - 'Why do I need to know about grass' then,
Jenny Patersons' web site www.horsemanshipnz.com
(under Diet). It has a huge amount of information on the physical
and behavioural issues that come from grazing the wrong types of
grasses for horses.
In the past week I’ve had two people contact me about their
geldings behaving like stallions and others noticing their horses
have ‘changed’ and are becoming pushy and not listening.
Clover is implicated here because it contains phyto-estrogens that
upset hormones and also contains pigments that lead to photosensitivity
which looks like mud fever (greasy heel) and sunburn.
The best way to figure out if grass is implicated in behavioural
issues is to remove the horse from the grass, feed non-rye/clover/paspalum
grass hay and supplements to assist with correcting mineral imbalances
that can exaggerate the behaviour.
Here is a wonderful story of one New Zealand farmer who ‘saved’
his horse by doing just that.
started using Alleviate on my gelding in autumn and found he was not
as stressed about leaving his mare behind when I took him for a ride.
I was so happy with Alleviate, I decided to start my mare (Missy -
pictured here) on it. She has had a great fear of being tied up from
previous negative experiences, and as soon as we would approach the
tie up rail in the past she was tense and stressed out and would run
Amazingly, after three weeks on Alleviate I am now able to drape the
rope over the rail and brush her without any anxiety at all. I would
recommend it to anyone.”
Vanessa Macdonald, Tas.
Lucy Prior at Gotcha Equine - Something else we are about
to add to our Provide It Plan is feeding your horses their hay first
before they have a hard feed.
By giving the horses 30 - 60 minutes of hay first before they eat
their hard feed it slows down the digestion of the nutrition in the
hard feed and helps increase the absorption rate. This is particularly
important for horses kept on a track or dry lot as their stomachs
won't have as much in them, particularly in the morning they will
be almost empty.
Hard food will pass through an empty stomach much quicker, possibly
not allowing as much nutrition to be absorbed. I have noticed that
the tox-defy also seems to be working more efficiently by feeding
some hay first before the hard food.
It may take a couple of days for your horses to get used to the reversed
feeding, mine looked at me in disgust for the first couple of days
wondering where their hard feed was.
Another tip which I'm sure most of you are already aware of is to
introduce your horses slowly from free grazing on grass to a track
or large bare yard.
If you change your horses diet drastically it can kill off a large
amount of the flora (good bacteria) in the hind gut that breaks down
the fiber. If this happens your horse may go off their feed and the
manure will go very dry. Try giving them a heaped table spoon (or
a Vit & Min scoop) full of Phsyillin Husk night and morning this
will help regulate the digestive system.
Natural Horse World Store now stocks the whole
Provide It range of products.
Do I need to Know About Grass?
Grass is one of those
things we take for granted if we have it, and wish we had it if we don't,
especially in times of drought.
If we have a paddock full of lush grass we think our horses are lucky.
But did you know grass can be just as harmful for your horse as much
as it's helpful in providing nutrients?
Recent research by people
such as Kathryn Watts from Colorado, has revealed that grass can cause
our horse to show slight lameness, shortness of stride, tie-up (azoturia)
after exercise, contribute to 'Cushing's Syndrome' and hoof abcesses,
and of course, cause laminitis and founder.
Many of our horses probably die early or are 'put down' because of the
problems they develop from eating grass either at the wrong time of
the day or year, or the wrong type of grass. In fact it has been proven
that animals who have their intake of calories restricted by 30-40%
live a lot longer.
In other words, people love their horses so much they feed them 'to
of the most common reasons for horses to be retired or euthanaised is
irreparable lameness and it's estimated that 80% of horses in the world
show some form of clinical lameness.
Most of these lamenesses originate in the lower 1/3rd of the leg with
a very high percentage in the hoof from 'diseases' such as navicular
and laminitis, abcesses and seedy toe (or white line disease).
While some stresses to the hoof such as navicular are related more to
the hoof form being out of shape due to shoeing and bad/neglectful trimming,
most others can be controlled through diet. Laminitis, seedy toe and
the abcesses that result from the hoof trying to rid itself of toxins
can all be fixed with a careful diet that controls the damage done to
the laminae inside the hoof.
Damage to the sensitive laminae cause them to seperate and destroy the
bond between the inner hoof structures and the outer hoof wall. When
this bond is broken, lameness occurs as it is a bit like us tearing
a fingernail from the skin below - it gets pretty sensitive until it
can grow more tissue and heal.
As the torn laminae grow down with the hoof wall towards the ground,
the dead tissue spaces (seperation of the hoof wall) allows bacteria
to enter and then you have seedy toe or white line disease.
Abcesses commonly occur to rid the hoof of the dead tissue from within,
especially when the horse has suffered laminitis and a large amount
of toxins must be removed. When the blood flow that carries these toxins
away from the hoof is compromised by shoeing or lack of movement such
as when the horse is footsore and cannot move much, then an abcess is
the only way to force the toxins out.
So what has this all got
to do with grass I hear you say?
Well, grass manufactures sugars in the form of non-structural carbohydrates
(NSC) and when these sugars overload the horse's hind gut, in simple
terms, it causes the gut to release toxins into the blood which then
flows to the hooves and effects the laminae as described above.
So, if we know how to limit the NSC to a safe level, then we can save
our horse from a lot of suffering and save ourselves from a lot of vet
Most people already realise
that a horse who gets into the grain bin and gorges, will founder, as
do ponies on rich grass in spring time.
This is the extreme end of the scale, but if we are more aware of what
is happening to our horse's hooves, they will show us that minor episodes
of laminitis (a major episode is called founder) are happening in response
to the grass or concentrate feed our horse is eating.
Commonly, horses become sensitive in their hooves when they have a minor
laminitic attack. You may notice your horse is reluctant to move forward,
takes short steps or 'plays up' when asked to circle. They will be footsore
on gravel or rocky surfaces, always looking for the edge where the grass
grows or the going is softer. That's what makes most horse owners reach
for the phone to call their farrier to put shoes on, when in reality
they should be restricting grass intake and buying a set of boots to
help protect the hooves in a healthy way when they want to ride.
Some footsoreness can
be due to lack of good hoof form ie; flat soles therefore sensitive,
but this is also just another symptom of mild laminitis. The soles appear
to have dropped but what's really happening is the hoof wall is seperating
and growing forward from the coffin bone because of a weak laminar attatchment,
causing the sole and coffin bone to become weight bearing and therefore
sensitive to direct pressure.
As you can see, the root cause of many hoof problems and therefore soundness,
is the damage to the laminae which is like velcro - it holds the hoof
The cause of damage to the laminae is commonly the toxins released from
the horse's hind gut in response to an overload of sugar.
The sugar overload comes from a high level of sugar or NSC in the grasses
the horse eats (even in the dried grass - hay) which is the reason we
need to know more about grass.
We need to know when it is safe to
allow the horse to eat grass or when the grass has a low level of
We need to know what types of grasses have lower levels of NSC and
which ones have a higher amount - usually those developed for the
beef and dairy industries to grow lots of muscle, fat and milk.
We need to know what affects the NSC content of grasses - like the
weather, fertilisers used, when it is cut for hay etc.

magnesium can help your equine cope with spring grass.
the spring when grass is growing faster due to an increase in rain,
sunshine and sometimes fertiliser, it produces excess potassium. Potassium
slows the uptake of magnesium which horses have a limited ability
to store. Magnesium uptake can be aided by the presence of sodium
which is why it’s important to have a salt lick available for
your horse at all times, but especially so at times of rapid grass
Modern day diets are often
low in magnesium and the high stress lifestyle of some equines leads
to an increased need for magnesium. Areas with acid soils and soft water
may not provide enough Mg in water and soil for the needs of performance
Magnesuim is a very important mineral. It helps regulate a number of
body functions. As well as regulating moods and muscle function, it
is essential in regulating some of the metabolic issues inherent in
chronically foundered horses, such as blood sugar levels and thyroid.
A lack of magnesium has been blamed at least in part for a number of
conditions including equine metabolic syndrome and obesity, both precursors
it is hard to overdose a horse on magnesium (they get diarrhoea when
they get too much), it is important that magnesium and calcium are fed
together since they "compete" for the same amino acids, be
sure the horse is getting adequate amounts of both. If you feed Speedibeet
which is high in calcium, or a small amount of lucerne chaff, that should
balance it out.
Which form of magnesium?
Epsom salt magnesium is the least readily absorbed, although some of
the magnesium does get taken up by the body so it can be useful in an
emergency situation. Magnesium oxide is next in line. Magnesium oxide
is the form found in most feeds because it is the cheapest. More digestible
magnesium is in the "chelated" form, ie it has amino acids
attached to make it more useable by the body. There are many different
chelated magnesium products available and all are better than magnesium
oxide in digestibility.
The magnesium in dolomite is as absorbable as that in magnesium oxide
but the problem is calcium and magnesium share some absorption pathways
and the body preferentially will take the calcium first. If the diet
already has an excess of calcium, some of the absorption pathways will
be blocked to both calcium and (as a secondary effect) magnesium. This
is why it is best to use a pure magnesium supplement first when trying
to correct a serious and longstanding magnesium deficiency. Once the
symptoms have abated, you should then switch to a supplement program
that contains both adequate magnesium and all other minerals in correct

Flush brings on Toxic Grass
It's wonderful to have
finally had some rain and with a tank full of water it feels like
the drought has broken. The weather is still warm enough to grow grass
but the lovely green tinge is already presenting problems for some
horse and pony owners.
When grass has been stressed
by drought and suddenly has a growth spurt, it contains toxins which
are designed to protect it from over grazing. Our domestic horses
not having a lot of choice when confined to small areas (less than
1,000 acres!) can be affected by this grass, commonly called the 'Autumn
flush'. Cases of lamintis in prone equines increase at this time of
year, almost the same as in spring.
Horses who haven't had
a severe laminitic epsiode may show minor symptoms such as tenderness
when ridden on gravel, or shortness of stride and refusal to jump.
Some horses can even show
signs of ' grass staggers' - which are exciteability, nervousness,
a staggering unsteady gait or trembling. An excellent site for information
of how mycotoxins affect horses (and these occur in other grasses,
grains and hay as well) is www.horsetalk.co.nz
Horses that show symptoms
of any being affected by grass or other toxic plants such as capeweed
and flatweed (false dandelion) do well if fed additional magnesium.
Magnesium plays a role
in the metabilism of the muscular and nervous systems. One very good
high quality source is a product developed in New Zealand called Alleviate.
It is an organic chelate - the highest grade available and inlcudes
boron which is required to reduce the excretion levels of magnesium.
Alleviate is now available through the
Natural Horse World Store and you can read a more
detailed product review here.

vitamins and supplements
can be one of the most confusing aspects
of feeding horses.
How do you know which ones to use? Or which brands are best, or even
if your horse needs them?
Here are some reasons for feeding supplements:
1. The pasture/hay
might not be providing the right balance of minerals or enough to
keep your horse healthy, epsecially if the soil is depleted. Horses
deficient in minerals often show signs in their coat and hoof health,
with skin conditions, faded coat colour and hoof wall cracks good
indicators that something is lacking.
2. The mineral/vitamin needs
of a horse vary according to age, health, workload and whether they
are breeding or lactating. A pasture pet may get by with just a salt
lick but if you don't want problems to arise when the horse is expected
to do something, then supplements are a must.
3. Supplements in prepared
feeds aren't always enough and aren't balanced to the roughage
your horse gets which should be 80% of the diet. Unless you feed the
exact specified amount on the bag the mineral/vitamin intake for this
portion of the diet is reduced.
4. Free choice minerals or
licks can not always be relied upon to provide everything
the horse needs. Minerals are generally unpalatable except for salt
which horses will seek out themselves and should be available in loose
form at all times. Licks may not give adequate intake especially in
hot climates or when the horse sweats.
Licks have molasses added to get horses to lick/eat them but they
still won't take in enough on their own especially when the horse
is low in the pecking order and by the time they get a turn at the
lick, the rest of the herd may decide to move on, so they feel the
need to go with them.
5. Health problems
may benefit from specific supplements for example horses suffering
from stringhalt respond well to magnesium as do those with laminitis
or behavioural issues caused by the toxins in some grasses such as
rye and kikkuyu. 'Big head' and facial bone bumps indicate a need
for additional calcium and 'tying up' could indicate a need for Vitamin
E and Selenium.
Supplements can improve coat colour and condition - the horse on the
left was fed supplements from the Natural
Horse World Store Both horses were otherwise on
the same diet.
While I am not qualified to tell you
which supplements to use and indeed there are so many variables, you
need to research what supplementation each horse requires.
My aim is to simply to raise awareness about a subject that is sometimes
neglected or ignored becuase its all too hard.
With the ability to search for information
so easily on the internet these days, there's really no excuse for
not looking into what your horse might require for optimal health.
There is also a wealth of knowledge
and advice available from independent Equine Nutritionists at very
reasonable rates (see the Services Directory)
and well researched books such as Natural Horse Care The Right Way available

to an organic material. In the old days, these types of minerals

Turns Gelding into Stallion – by Vanessa Smith
Last autumn, I was at my wits end as to what to do with my 14 year
old gelding that I have owned for two years. Echo is a beautiful
grey Arab cross. I had always thought he was a rig as he loved mares
and acted a bit like a stallion.
Echo was given to me because of his stressed out and over-reactive
behaviour, resulting in past mistreatment. He is a sensitive horse
and demands patience but I was becoming afraid of him.
He acted so much like a stallion that he was unsafe to be around
when he was near a mare. My mare came in season and he mated her
fully. He could not concentrate when I took him away from the mares
and would head toss and roll on the ground, sometimes displaying
mild signs of colic.
My own baby was six months at the time and I thought that with the
limited time I had, I would not be able to change his behaviour
through the hours of training he’d need.
I was also desperate to ride again and Echo was my only riding horse,
so I had long nights full of anguish and frustration. One day when
I went to feed the horses Echo nuzzled me and started making deep
snorting sounds and then he struck out with his front hoof and when
I had a woman massage him the next day and he was unhappy and went
to bite. I was so upset that I thought about giving Echo away. It
was a hard decision as I felt Echo and I, had over the past two
years formed a good relationship but now he seemed unreachable.
I sent Cynthia an ad to put on her website, looking for a home for
Echo. She said that he would be unable to find a better home than
mine because of his sensitive nature. She also sent me a book that
saved Echo and me.
“The Key to calm healthy horses” by Jenny Paterson helped
me understand what was happening to Echo. As I read the pages I
cried, the book was describing Echo exactly, Tossing his head constantly,
sour cranky behaviour, walking all over me, unable to concentrate,
intense stallion behaviour.
I realised that the clover paddock he was in was creating a toxic
effect that resulted in all the above behaviours.
I removed Echo off the clover and also fed hay and began to feed
him Alleviate, which is a magnesium supplement and Supreme Vit &
Min. and over a few weeks Echo slowly began to change.
I also came across a product called Attitude blend from Country
Park Herbs, designed to balance the hormones of horses.
During the winter I was amazed at the change. Echo has always tried
to mount my mare, yet just a week ago she came into heat and he
didn’t bat an eyelid. Today I went out to brush Echo - he
stood quietly with the mares around and without a halter on he just
stood there and enjoyed the experience, and so did I.
I am still aware that there is clover on my property and I know
that even when he gets to munch on some he changes. I also know
that the spring grass and autumn grass can change his personality
in a day.
I am happy now armed with all this new positive information, and
know that Echo and I are destined for a long life together.
