THE LATEST ON GASTRIC
ULCERS
Whilst most people
are aware these days that at least 90%
of racehorses suffer from ulcers, they
are not so aware when it comes to horses
within other equestrian spheres of activity.
The presence of an ulcer is far more common than owners
realise.
Vets in Amercia, as is so often the case, seem
to be far more advanced than in the UK and have been busy
bringing ulcers to the attention of the general horse owner. This
is because their research has shown
that the incidence of occurences appears
to have risen
in recent years amongst horses which do not necessarily lead
particularly stressful lives.
The
reason for this is obviously the improved
equipment available to vets enabling better , quicker and easier
detection of ulcers, but also because so many horses are fed diets which
are so far removed
from their natural foraging instincts.
Tests on
15 show horses that were not performing
to their best or just seemed to be a
bit "off" or did not gain
weight despite a healthy appetite or
showed evidence of teeth grinding, dull
coat, etc. despite daily turn-out,
were scoped.
The results
showed that 8 horses had an ulcer. Whilst
this does appear to be a huge figure,
it is actually just over half, so that
in itself is food for thought.
Amercian
vets are also developing a much easier
way of ulcer diagnosis without the need
for an endoscopy. It would seem
that by analysing a urine sample for
the presence of sucrose. Sucrose
molecules are not normally present in
a horse's urine or blood as they are
too large to pass through the stomach
lining and are broken down as soon as
they hit the small intestine.
If
the stomach lining is damaged due to
ulceration then the sucrose molecules
can "escape"; they are then
filtered out of the bloodsteream by
the kidneys in the normal way as any
waste material and so end up in the
urine.
Let's hope British vets
catch up as this is a much simper way
and of course non-invasive way of detecting
ulcers - and without the need for sedation
either.
RAGWORT POISONING
Dr. Derek Knottenbolt and his team at Liverpool
University are confident that the blood test for ragwort poisoning
they are currently developing will be routinely available by the end
of 2004. The test will hopefully save lives - 6,500 horses died last year - and
whilst it is sadly accepted that some will continue to die, a good
many will have the chance of being saved as owners will be able to
have their horse tested if they suspect ragwort is being
or has been ingested long before irrepairable
damage is caused; it will be very reassuring to know that a horse
can be helped if it has had access to ragwort despite the best
efforts of its owners to ensure against this - e.g. in
hayAs usual with all research projects, it
has been lack of funding which has delayed progress (at one
point earlier this year it was thought that the project would
be halted for a while) and so financial assistance is still required
to keep progress in the right direction.
Meanwhile, despite the introduction of the
Ragwort Control Bill, owners will still have to remain diligent and
keep grassland ragwort free - if you have not already got one
invest in a "Ragfork" which is specially designed to dig out the
toughest of clumps!
It must be remembered that whilst poisonous to
horses, ragwork is the staple diet of many of the country's native
insects, etc. Thus in no way can it be completely eradicated without
ecological implications and, being fair, we should not expect this
as, after all, it is up to us to protect our horses. However
the bill will at least make landowners more accountable for
ragwort clearance where it can be proven to be a hazard to
equines.
CRIBBING
The latest reseach results
have revealed that some horses may crib because of the build up of
acids in the stomach; the action of cribbing produces saliva which
then neutralises the acids in the stomach.
Whilst there are
those individuals who crib because of boredom, poor environment,
etc. (and obviously these factors should be addressed as a matter of
urgency) and there also may be those that inherit the trait as there
is evidence of very young foals cribbing, the acid build-up
notion is indeed a very valid one and one which we
support.
We have a horse that has
cribbed for as long as we have owned it (an racehorse rehab case);
not happy to fit a collar but not happy either to let the horse crib
because of the health implications, we lowered his stable door
height and fitted a chain at standard door height (to keep him
in!). The horse was not able to crib on the chain so we have
successfully put an end to this behaviour when stabled (he will
sometimes crib when out at grass which puts paid to the boredom
theory in his case). Mindful that the horse could stress
because he could not crib we watched him very closely for signs of
negative behaviour etc. Having successfully stopped the horse from
cribbing, the immediately noticeable result of this was that he
began to drink more water. This supports the acid
theory. The horse has not displayed any other adverse
behavioural signs and at 21 years of age is as fit and happy as he
has ever been.
There is now a new product on the market
from FEEDMARK called SETTELEX which is an antacid; given as a feed
supplement it neutralises stomach acidity. so if your horse cribs or
windsucks we recommend that you try it as these "vices" are
detrimental to health and well-being but yet there may be a
valid reason for it.
Please contact FEEDMARK on
0800 585525 (next day free delivery). The product is also
available from retail outlets.
LAMINITIS
Be mindful that, although laminitis is
associated with the spring and summer, it can still strike anytime
really as it not just a disease which affects fat little ponies
with access to too much lush grass - stabled horses can also
be affected; also some horses/ponies can be affected by the addition
of certain feeds to their diet.
Most feed companies have telephone
helplines which you can call for advice and information about
suitable products for the laminitic prone so if you have any doubts,
it is best to make contact.
Also the Laminitis Trust has set up telephone
helpline so that worried owners can ring for advice. The number is
0905 105 105 1.
The helpline operates Monday – Friday between
10.00am and 4.00pm and is manned by a veterinary expert who can
discuss laminitis related problems. Calls cost a £1.00 per minute
with money such raised being directed to much needed further
research.
Robert Eustace, the Director of the Trust, has set
up a website – www.laminitis.org - which also has valuable
information relating to Cushings Disease.
Whether or not you
have owned a horse or pony which has suffered from either of these
"ailments" or worse, lost one (sadly I am amongst those that have)
the website makes important reading. You can go there right now by

The Animal
Health Trust has announced that a thoery which w researched years
ago but not proven, has been reveiwes and very compellin evidence
ound as to the cause of this killer disease. It seems that
grass sickness is indeed linked to the toxin botulinium.
Tests have
shown that animals injected with a serum derived from infexted
horses actually developed resistance to the disease, thus the serum
obviously contained some form of anti-toxin.
Results from
post mortem examinations have established that infected horses had a
much higher amount of the toxin in their intestines than that of a
healthy horse.
It is now
hoped that a vaccine can be developed against the botulinium toxin
as soon as possible.
Let us pray that this indeed will be the
case and finally we can do something to protect our horses from this
deadly disease. As one who has lost a horse through grass
sickness and follows the progress of research very avidly, I am
delighted that there finally looks as if there might be some light
at the end of the tunnel. Rowena
