Tobiano Information "Breeding Coloured Ponies"
Can
coloured foals be guaranteed? Yes
they can, we are currently breeding guaranteed to breed colour to a plain coloured stallion or mare. This is all dependent on genes. Homozygous (TT):
This means that the pony carries 2 copies of the Tobiano
or colour gene. When bred,
this pony will always pass on the colour gene to its offspring. Heterozygous (nT): The pony is a Tobiano or colour carrier, but only carries one copy of the gene.
Therefore 50% of the
time it will produce coloured foals, and 50% of the time it will not. Negative: (nn) the horse does not carry the Tobiano or colour gene, and cannot ever produce coloured
offspring.
All this may sound complicated but it is easy to get a pony tested for the right gene. If your pony has the very special gene then you can guarantee that you will
get a coloured foal 50% of the
time. If your pony tests for 2 copies of this
gene then it is very special and will always breed coloured ponies. With kind permission of D Reeves, Animal Genetics 2007 Coloured horses and ponies, often referred to as Piebald, Skewbald, or Tri-coloured
have long been amongst the most desirable of all equine specimens. Despite their rising popularity, little thought has been
given to the genetics involved in creating their unique appearance. This article briefly explains the Tobiano gene and the testing available
for this common coat colour pattern.
The Tobiano gene is a dominant gene expressing in both horses
that are heterozygous and homozygous for Tobiano. The gene is associated with the loss of pigmentation, leading to a horse
with large white markings
in certain defined areas. These markings can include some or all of the following: White oval-shaped patches crossing over the back. White Legs, extending from the hocks and knees down. Neck, face, and front of forelegs are generally unaffected. A Tobiano horse will display one or more of these traits,
although the extent of these Tobiano markings can vary. A ‘Minimally expressed’ Tobiano horse is coloured, but
the pigment loss (the white areas) is often much less noticeable than what is commonly seen on a Tobiano horse. Inheritance from Parents In the simplest terms, a foal randomly inherits half of its genetic makeup from the dam and half
from the sire.
The principles of how the Tobiano gene is passed from parent to offspring
apply to any other gene or
genetic trait. A horse that does not carry a Tobiano
gene is Tobiano negative. In science, we give this a code and refer to a Tobiano negative simply as ‘nn’. An nn
horse displays no Tobiano markings and will not pass the Tobiano gene on to its foals. A horse that carries a single Tobiano gene is referred to as ‘Tobiano heterozygous’
–the word heterozygous in reference to genes means ‘two different genes’. Tobiano heterozygous horses are
referred to as ‘nT’. An nT horse displays Tobiano markings and will statistically pass the Tobiano gene on to 50% of its foals. A horse that carries TWO Tobiano genes is referred to as
‘Tobiano homozygous’ –the word homozygous in reference to genes means ‘two of the same’. Tobiano
homozygous horses are referred to
as ‘TT’. A TT horse not only displays Tobiano markings, but will pass the gene to 100% of its foals.
So, a Tobiano horse can carry either
one or two Tobiano genes. The number of Tobiano genes the dam and sire carry will ultimately determine whether its offspring
can potentially be heterozygous or homozygous for Tobiano. The
following points simplify how carrying one or two copies of a certain gene affect the inheritance of that gene to the offspring. The offspring inherits 50% of its genetic makeup from the dam and 50% from
the sire. If a horse has two copies of a certain
gene (homozygous), it is guaranteed to pass one copy on to its offspring. If a horse has one copy of a certain gene (heterozygous), it is 50/50 as to whether or not it will pass the
gene on to its offspring. Here is an example of the above points, using the Tobiano
gene as mentioned before
The offspring
in the chart above is heterozygous, 50% of the time it will pass on the Tobiano gene to its own offspring and 50% of the time it will not. With some basic information of the Tobiano pattern and the
genetics involved explained above, the following is a description of the possible results obtained via genetic testing: Tobiano Negative (nn): Solid, non-Tobiano horse. Tobiano Heterozygous (nT): Positive for the Tobiano gene and will produce both
coloured foals and solid
foals on a 50% likelihood basis for each. Tobiano
Homozygous (TT): Will always produce coloured foals regardless of the mate. By utilising Animal Genetics’ testing services, you have the ability to predict the ratio
of Tobiano foals you can expect, as well as other equine genetic tests. Animal Genetics has developed a program to assist horse breeders in predicting possible
offspring coat colours. The ‘Coat Colour Calculator’ can be reached by following the link below: DNA Tests Available At present, genetic testing for the Tobiano pattern is carried out by testing
for a mutation found in the KIT gene, which is closely linked to the Tobiano gene. Currently, there is not a direct test for
the Tobiano gene, but the outstanding accuracy of this test makes it more than a viable option for any serious enthusiast or breeder.

Hair Sample
Collection
Collect sample
by pulling (not cutting) 30-40 mane or tail hairs with roots attached. It is important that you pull the hairs and confirm
that the actual root of the hair is being collected. The root contains the genetic material of your horse that is needed for
DNA testing. Therefore, cut hairs do not provide an adequate sample. Place the collected hairs of each horse in a separate
zip-lock bag labelling the bags accordingly with the horse’s name or identification number. Complete a submission form
for each sample and
send the form along with hair sample(s) and payment to Animal Genetics. Please note, that because this is an ‘indirect’ genetic test for Tobiano, there is
a small percentage of Tobiano horses which we have found to test as ‘Negative’ using this technique. This has
occurred in less than
a dozen horses, from 3,000 tests. Animal
Genetics also offers a number of other Equine genetic tests, some of which are relevant to Tobiano horses.
What is needed to enjoy these wonderful pets.
To keep a couple of these lovely ponies you would need a paddock with at least 1 acre of well kept
grass land with a shelter or stable and clean fresh water must be available. They are relatively cheap to keep, eating grass
when available or good hay. (Ponies are much happier if they have a companion so it is best to have two if possible).
Cost of keeping a couple of ponies.
The cost to keep a couple of miniature Shetland
ponies per week is as follows:- If not on good grass then one miniature pony would eat just one or two bails of hay per week
at £2 - £4 per bale. The ponies would need to have their feet clipped three or four times a year which costs about
£10 - £15 each time. They would need worming regularly at eight to twelve week intervals depending on the product.
This costs about £3 - £4 each time as a £12- £16 syringe will do four little ponies. (One syringe
will do four mini Shetland's or one four times). Veterinary costs are rare if you look after your ponies well.
So total cost of keeping a mini Shetland Pony for a year is aproximately £140 - £200 excluding vet fees which
are rare. This is actually cheaper than keeping most dogs if you have a large garden or some grassland.
How we monitor the pregnant mares
Always watch your mares 24 hours a day in the last month prior to foaling.
Miniatures are much more prone to having some problems than
larger horses.
We use CCTV to watch the mares in the stables and the barns.
We have cameras in all the stables which are linked to all the TVs in the house.
Darren watches
the ponies at foaling time from early evening until the early hours of the morning.
When a foal is coming Darren tends to be there to sort it out, sometimes two or three times a night.
I do not know how we keep it up but it is very rewarding when
we succeed and save foals that would have died had we not been there.
I estimate that I save about 60% of the foals by being there and acting to save the foals as necessary.
With regard to foaling monitors, we have tried most and they
all have there faults which have cost lives, we now choose to use our eyes and cameras with the odd foaling alarm used as
a backup.
Actual foaling tips
The gestation time for a horse is approximately 11 months, or 340 days but in miniatures
it can be as early as 315 days, we have found that 326 days would be a good average. It is best to be in attendance at the
foaling’s because the mare may have a problem and you can frequently help them and save the foal, mare, or both. We
give our mares a tetanus injection one month before foaling. This also gives the foal immunity which is important.
You need to have all the preparations made and ready to go about 2 weeks before the first birth is expected; you never
know when it might happen early. Have a clean stable prepared with clean, dry straw bedding. We bring the mares in about 2
week’s before giving birth so they are comfortable and settled. Sometimes we let them run in the yard or paddock during
the day when we can still watch them as many of them will give birth in daylight hours.
We make up a birthing kit to carry us through the season. This consists of:
Tail
wraps.
A small bucket for warm water and Hibiscrub and a clean cloth to clean mare's vulva and bag.
Purple spray
or Iodine spray to put on the umbilical stump.
Micralax Enema to give to foal after birth if needed to help get rid of
the meconium or first stool.
Clean towels to dry off the foal.
Hibiscrub disinfectant to clean your hands and arms.
Lubrel lubricant.
There are some signs to watch for signaling that a birth is imminent. The mare’s
rear end around the tail will go soft as the area starts to relax. The vulva will start to lengthen as the mare dilates. The
mare's teats will sometimes wax up 12 to 24 hours before foaling. A small bead of waxy milk will appear. The mare may
stop eating, be restless, getting up and down and rolling to get the foal in position. She may start to make a few sharp movements
looking around at her belly. She may sweat when very near to foaling. A bubble may appear from the vulva, or the water sac
may break. Any or all of these things might be noticed and should be taken as a sign of an imminent birth.
If you do not have cameras and keep going to the stable to check on the
mare then you will need to be whisper quiet as a mare can and will stop foaling even with just one minute to go if she senses
danger, this is why very few foaling’s are ever witnessed without surveillance cameras.
When the mare lay's down and starts to get her contractions, this is when you can
move in with her to help. You need to be sure she is not lying against the wall so that it is easier for you to check that
everything is coming alright, minis are small enough to pull around to a better position.
We usually help to pull the foal out once it is coming correctly and especially on
a first timer, we have found in the past that the mares sometimes rest while the foal is half way out and this is no good
for the foal if there is prolonged pressure on the chest or umbilical cord.
Be sure to get the sac off the foals head immediately so it can breathe.
When possible let the foal lie for a minute or so with the umbilical cord attached
as often blood is still being pumped into the foal for a short period before the umbilical stump seal's ready for the
detachment when mum get's up. If the cord breaks to quickly and blood is flowing out of the foals umbilical stump you
must put pressure on it quickly with your fingers for a minute or so to allow the valve to close then spray the area with
iodine.
Mini foals range in size at birth from 12”
to 20”, weighing from 12 to 20 lbs. After the foal is delivered, both mare and foal may rest for a few minutes. We usually
move the foal to be in front of the mare after a couple of minutes so she can lick it dry and start bonding with it, but only
do this if the umbilical cord has broken. If the cord is still intact leave them alone as long as they will lay there. When
the mare stands, the cord with come away from the foal cleanly, this is the time to spray the umbilical stump with the purple
spray or iodine spray. If the sac is still hanging from the mare tie it up in a knot to keep her from walking on it and to
help it come out of the mare clean. Never pull on it to get it out. If the mare hasn't passed it in about three or four
hours you will need to call the vet. Always check the afterbirth to be sure none was left in the mare, or save it for your
vet to check.
After all the business of birthing
is over, then it is time to imprint the foal. We sit down in the pen with the mare and foal. We rub the entire body, with
a towel and our hands, this helps to desensitize the foal and helps it to bond with us as well as its mum.
The foal will then soon stand on its own start to search for the teat.
We never interfere at this time as it can confuse the foal. We leave nature to happen. The foal needs to drink the colostrum
from the mare within ideally the first few hours so that it gets immunity to all the nasty bacteria and viruses. If after
maybe four hours the foal has not found the teat or has started sucking on the walls, you need to take action as shown belo
Foal not suckling
Check the mare to see if she is still well bagged up, if the foal has suckled you can
usually tell because she will be more comfortable and the foal will be settled for a while. If you think that the foal has
not sucked yet then we milk some colostrum from the mare and give it to the foal by a small 5ml syringe squirted into the
foals mouth.
We give the foal as much as we can until
it is happy and settled then we leave the mare and foal for another two or three hours knowing that the foal has had its colostrum.
We usually find that this first un-natural feed will give the foal an amazing boost of energy so that it will usually be able
to find the teat after a short sleep.
If this does
not work then we milk the mare a little and start lying on the floor with our arm under the mare with a little syringe full
of milk, one of us guides the foal to the syringe and when latched on we guide the foal to the teat. It is tricky work but
it does usually work. If it does not then you need to keep milking the mare and feeding the foal by syringe. We have never
had any success at getting a foal to suckle an artificial teat on a bottle.
As the foal gets stronger it will eventually find the teat itself by the second day.
If not then the foal may have a problem with it's sucking
reflex or short tongue or it's swallowing reflex or something else. Veterinary advice is needed now.
EMERGENCY Placenta Previa or Red bag.
EMERGENCY
In brief if you see a bloody liver coloured bubble coming out of your foaling mare,
be ready to slit it straight away and get the foal out as fast as you can because it is suffocating.
In a normal foaling the first thing that you see is a fairly translucent
bubble usually with a front foot followed very closely by the other front foot and nose. If instead of seeing this cloudy
clearish bubble you see a red bag that looks like liver or velvety textured, that is the placenta which should have ruptured
allowing the amniotic sac to emerge from the vulva first.
This occurs usually only if the mare has been in hard labor for a while and the placenta due to the terrific forces
of contractions has separated from the uterus. Once that happens the foal is no longer getting oxygen through the umbilical
chord, but instead is starting to die or suffocate. This happens sometimes if the foal is mal positioned and the straining
of the mare finally separates it, or can be caused by the mare's being fed with haylage infected with an endophyte (type
of mold) that causes tough placenta and other foaling problems. It can also be caused by some trauma to the mare such as being
kicked very hard or some other disturbance to the cervical area.
When you see a red bag, the first thing is to quickly open it and it is very difficult to do by hand, so use a sharp
knife to slit this bag. Don't worry about sanitation, just worry about speed. Then try to feel how the foal is presented
and get it out as quickly as possible.
If you get
the foal out very quickly you may be able to save it, but if the placenta has been separated too long the foal may be born
dead. We have saved many foals by being fast and ready for problems. Again only full camera surveillance works with someone
watching all the time.
Sometimes a saved foal will
still die later if it was starved of oxygen for two long. Apparently retardation can progress quickly although at first they
seem normal. Some of them would fall asleep easily and stay asleep too long. This is sometimes called "Sleepy foal".
Red bag foaling's are not so common, they can sometimes
affect many ponies in many breeding studs in certain years so the weather, grass and feed can all cause this problem occasionally.
Leg back
Note: Do not panic, if you know what to do it is fairly easy to correct. If you have a leg and a
nose coming ok, without bursting the white bubble try to feel for the other leg. If it is not there then cut the bag and feel
again with lubrel on your hand and arm. Do not let the whole head come out without both the legs being in front of the nose
or you will have a dead foal and ruined mare. This can sometimes be difficult if the mare is pushing hard, you just have to
get stuck in and push the foal back in as hard as you can, sometimes you will then feel the foot pop forward. if it does then
pull it forward to be infront of the nose with the other leg but not equal to the other leg as the thick leg joints need to
come staggered.
If the foot does not come forward
as you push the foals nose back into mums tummy then just keep pushing until your whole arm is at full stretch inside the
mare, usually the feet pop forward at this point, if they dont then there will now be enough room in the tummy to hook your
middle finger around a knee joint to pull the leg or legs forward. Once you are happy that the feet are in front of the nose
pull your arm out and let the mare push the foal out if she still has the energy.
If it has been a long time messing about you may need to try to pull the foal out yourself by gripping
the front legs inside the mare and pulling it out as she contracts. Sometimes a foaling rope can help but we have rarely had
to use it.
Head back
As with leg back you will feel to see if everything is coming ok. If you ever feel two ears or whatever
you feel feels wrong, I have learned to just push the foal right back in again. This may not be correct as i am not a vet
but it usually works for me. One the foal is back in the larger tummy area it is easier to manipulate the foal until you find
the feet and the nose.
I once had a foaling where
I could not make out what I was feeling, everything was a blob, we called the vet and to my suprise he put his arm in and
pulled the foal straight out. I was ammazed. He later told me that the fetal sac was around the foal and when he put his arm
in he knew straight away what this was by experience and pierced the sac with his carefully sharpened fingernail which he
keeps during foaling season. The foal was born dead and the vet said that it had died prematurely which is why it ended up
in a tangled ball.
Delivering the Breach Presentation Foal
We have only once had this problem and we lost the foal at that
time.
I have found a web site which explains this
situation well. Please click on the link below.
http://www.scottcreek.com/BreechFoal.htm
Ideally to ensure the well being of your ponies
you need to have good, weed and ragwort free grass. Ideally horses also like clover and mixed herbs in the grass but if possible
not buttercups.
A cheap way to clear most weeds is to use a product called Agretox 50 to spray the land with a sprayer
on a tractor or to use Grazon 90 if using a back pack sprayer. Well managed grass land can produce much more good grass eating
than badly managed land. We have found that the regular use of 25.5.5. fertilizer applied twice during the growing season
works miracle's. It is important to make sure that the land has a pH of 5.6 to 5.9 as grass grows better at this level.
We are in an acid soil area and so have to lime our land every six years with 3 tons per acre to keep the pH right.
This costs approximately £17 per ton of lime including the spreading.
It is also best to get your soil tested
for mineral deficiency, we did this and found that our soil was lacking magnesium which horses need. We have solved this problem
by the use of a relatively cheap product called Grass track which costs about £12 a bag which is enough for an acre
of land per year.
The regular use of a chain harrow or tine harrow are recommenced as they bruise the grass and
loosen the surface of the soil making the grass get more dense which then helps to suppress the weeds. If weeds are a major
problem in mid summer then it is best to cut them using a topper. If you only have a few acres of land then a local farmer
will usually perform these tasks for you for an appropriate fee which is usually much less than you think.
If you are the sort of person that would like your life to be
fulfilled with something special maybe like owning a miniature pony or foal then try it.
Some very useful information to help you on buying a good miniature Shetland pony.
1. Beware when buying a pony if you or the owner cannot quietly
walk up to it in the middle of a field and put a head collar on it.
2. Beware when buying a pony from an auction, ask the seller lots of questions to try to make sure that you know
what you are buying. Ask for recommendations from someone else who knows the pony. There are many breeders that now "farm"
these ponies and then round them up at sale time, fit a headcoller and sell them cheap. The unsuspecting buyers of these terrified
ponies or foals think that they have a bargain until they let them out in a field and then cannot catch them again.
3. If small size is important to you then never accept a ponies
height, even when written on a passport or sales list. Always take your own measurements from the highest point of the withers
at about the 9th - 11th vertebrae to the floor using a measuring tape or stick. You may sometimes find that most ponies are
not as small as the owners say they are.
4. Always
check the passport markings against the ponies to make sure that it is the right pony (All ponies should have a Shetland Pony
Stud Book Society or (SPSBS) passport). This is now more important than ever with DNA testing now being so common. Please
check out our links to the SPSBS for lots of other information abort the breed and the showing of these wonderful ponies.
5. A discerning breeding-buyer should buy for good
conformation and good bloodlines firstly, colour is or should be of secondary consideration having acquired the correct quality
bloodline. However if coloured ponies are your preferred interest because they sell for more money then please be aware that
it is very difficult to breed good quality well marked coloured ponies and so there are much less of them around which is
why they cost more.
6. We have found that most good
owners and breeders will have their ponies inoculated for Tetanus every two years and this will show in there passports. If
owners are prepared to pay the small cost for this it usually means that the have loved and cared for their pony properly.
The best owners and breeders will sometimes go much further by regular worming and even regular flue and strangles jabs.
7. Be prepared to pay a little more for something special, at
the end of the day you really do get what you pay for if you follow these rules.
8. Follow your instinct, if you like the people that you are dealing with and get there trust then
go with it.
Over the years we have learned a lot
about keeping and caring for miniature Shetland ponies. We have read many books and sought all the information that is available
on the internet.
Surprisingly we have found that
there is actually very little information that is relevant to miniature Shetland's.
Worming Advice
The most common problem in horses these days is caused by the Small Redworm (Cyathostomin).
This small worm is now the most common cause of gastro problems in miniature horses which end up resulting with Hyperlipeamia
which is very serious and life threatening. All miniature breeders need to be aware of the fact that these worms are the most
common problem worm around and that they need to be controlled effectively and regularly.
The best way to control most types of worms these days is to use Equest horse wormer
to rid your horses of most normal worm infestations, twice a year and then use the Equest Pramox wormer twice each year to
control all the usual worms but to include the tape worms which most other wormers do not control.
These wormers are the most effective available but they need to be administered carefully
as they can easily kill a pony if they are given in a higher dose than they should be. Please use a weigh tape to assess your
ponies weight and then dose accordingly. An equest wormer may cost £10 or so but it may do five miniatures so it only
costs £2 for each.
Please do not try to cheat
with cheaper wormers as they just do not work any more, if you cannot afford £2 per pony four times a year for wormer
then you should not be owning and breeding these special tiny horses.
Smaller Horses Are Different To Larger Horses
We have found by experience that miniatures suffer different
problems and sometimes more serious problems than
larger horses. For example hyperlipeamia is a common and serious problem
with miniature ponies which is where the liver clogs up with fat. This problem does not seem to occur in larger horses and
so very little study has gone into the condition. For more information see Hyperlipeamia below.
Minis Are Rarely Poorly
In general mini Shetland's are rarely ill if they are kept well, but owners need
to be aware of the main problems that can occur from time to time.
Zooepidemicus
The most common problem that can occur in young miniatures is something called zooepidemicus,
it usually affects foals and sometimes older ponies and the symptoms are usually just a snotty nose but can also make the
pony feel a bit down for a few days. The best treatment for this is nothing but time which is usually three months. This is
quite contagious and will usually go through most of the foals that are in the same field. It can also give symptoms similar
to strangles. If it does no treatment is necessary as this is not a serious condition. Here is a detailed piece about the
condition by Ben Moves MA VetMB MRCVS.
MINIATURE
"COUGHING" HORSES
This is the story of a small group of adolescent friends and an embarrassing
social disease.
Not uncommon. In fact, almost normal in their age group but nonetheless very debilitating on their performance
in the Show ring. They had a cough and the snots.
Yearling horses and ponies often develop a cough. This can be accompanied
by the complete range of symptoms from frequent coughing, inappetance, high temperatures, clear and runny nasal discharges
to green thick nasal discharges and so on. Some untreated conditions can become very serious and should always be seen by
a vet.
The causes of Upper Respiratory Tract Disease in yearlings are many. As a rule of thumb, clear runny nasal discharge,
off food for a day and then coughing is often caused by a virus.
The most common URTI virus is Equine Herpes Virus, type
1 or 4. In fact, investigations have shown that up to 85% of 2 year olds have scroconverted (i.e. been exposed and developed
an immune response to Respiratory Equine Herpes). Unfortunately, the immunity is short-lived. Vaccination to EHV 1 & 4
is available from your vet. It is not required for showing (unlike influenza vaccination) and boosters are required every
6 months.
Influenza is another URTI and can be severe. It is less common due to vaccination. Vaccines are frequently
updated to try and keep up with virus mutation.
There are other URTI equine viruses including Rhinovirus of which there
are several types. These infections tend to be less severe although this is not always the case.
Viral infections are
often followed up by secondary 'opportunist' bacterial infections. Although horses and ponies can fight these bugs
themselves with rest, antibiotics often help and may be necessary in some cases. Obviously, but rarely, pneumonia can be a
complication.
Our little group of valuable showing miniature yearlings, however, had green snotty noses, not running,
just crusty. When they started coughing they had a day or so of being 'off colour1 but certainly carried on eating. Within
a few days they had the full blown disease.
Not very
dramatic. Coughing, several bouts a day. And the snots. On examination the yearlings also had a very characteristic sign:
the sub-mandular lymph nodes were swollen. The glands just inside the back of the lower jaw on both sides (normally marble
sized) were egg-sized and sore to squeeze.
They didn't start at once. First there was one, and then a week or so
later another developed the symptoms. Attempts at isolation just prolonged the onset of eventual infection. After a month
the whole yearling group had it. No other age group was affected.
The symptoms were never that bad. Just a cough, snots
and swollen glands under the jaw. Powdered antibiotics and Ventipulmin (an oral bronchodilator) seemed to help for a while,
but the symptoms didn't really go away.
After a month and when it had become obvious there was group involvement
I investigated more carefully. I took a nasal swab of the most recent case. It isolated beta haemolytic Streptococcus zooepidemicus.
A common bacterium that often lives in horses' and ponies' upper respiratory tracts but can cause disease, especially
in young stock - especially in yearlings.
The most common treatment in most horse industries e.g. racing, is to leave
the horses alone
and allow the disease to run its course. This can take time. Up to three months, or more........
But SHOWING MINIATURES don't have the time. They should be showing. Some say that horses take so long to recover from
the symptoms because they are so mild that the immune system takes longer to realise that it has a problem.
I admitted
two of the group to our clinic. One was the most chronically (longest) infected, the other the most recent. I x-rayed their
chests. They reminded me of my previous days in small animal practice - but the x-rays were normal. Unfortunately, I didn't
have a fibre optic endoscope small enough, so I took a blind tracheal wash using a mare catheter and sterile tubing. All the
lab grew was beta haemolytic Streptococcus zooepidemicus.
I spoke to the Animal Health Trust. I spoke to a specialist
vet in the USA. We opted to treat the group with intra muscular cetifur (Excenell) daily for 7 days. The symptoms had disappeared
by
day 4 ........... BUT a week after we finished treatment back they came, COUGHS, SNOTS
and SWOLLEN
GLANDS.
Now, none of the glands abscessated. This can happen with this bacterium although it cannot cause true Strangles
like Streptococcus equi. However, it did hide from the antibiotics in a similar way by living inside lymph node cells.
Other treatments were tried, including immune support and homeopathy. These may well have helped. But at the end of the
day, the best and only treatment was time. All the symptoms went after three months. Almost to the day.
Gastrointestinal Tract
The most common serious problems that seem to affect the miniature ponies more so than
larger horses, especially ponies under 31" are with the gastrointestinal tract. These problems when they occur are very
hard to cure because the treatment and drugs that are available can often cause liver failure by Hyperlipeamia before getting
on top of the actual problem. The stomach of a horse is very different to that of a cow, cows can eat or be fed all sorts
of bad and moldy hay, straw, haylage and silage without hardly ever having any problems. The stomach of a horse is very different
and much more susceptible to problems which are often caused by poor quality hay, haylage and silage.
Haylage Is Bad For Small Horses
We know many people who feed haylage, we used to ourselves a few years
ago, the ponies love it, but often it contains toxic mould and bacteria which the ponies livers cannot deal with for long.
We also found that haylage causes placenta previa or red bag during foaling. We would recommend never to feed haylage to pregnant
mares especially or any miniature ponies on a regular basis with one exception, if you have a pony that has gone off its food,
try some fresh haylage for a short time until the pony is eating well again.
Colts and Stallions Are More Resilient
We have found that stallions and colts seem to be much more
resilient to illnesses than there female counterparts even when being born, If you are going to loose a foal it always seems
to be a filly. It would be interesting to hear from other breeders if they have had any cases of illness with their colts
or stallions.
Salt Licks and Naff Blood Liquid
One of the most important things that we believe will keep ponies healthy
is making sure that they have regular access to a salt lick, real chunks of rock salt are the best but there are plenty of
salt blocks available.
We have also found that giving a ten day cures of Naff Blood Liquid to a pony that is a bit down
and not eating properly seems to work well. It is a quick and tasty way of getting the correct balance of vitamins and minerals
into the pony. We have also tried the Red Cell liquid but the ponies do not like the taste of that.
Strangles
Strangles is a very common condition in many horses large or small, it is usually diagnosed by finding
an abscess or swelling under the throat, it can be very serious in larger horses but does not seem to be so bad in the miniatures
as we have never known anyone who has lost a miniature pony with strangles. If you know different please let us know. It is
very contagious and so ponies diagnosed with this need to be isolated until the abscesses burst and then kept isolated for
another six weeks. Most ponies are not infectious after this time but a few can continue to be carriers for up to six months.
Here is a piece by
Hyperlipeamia
Hyperlipeamia is the most common serious problem illness in miniature Shetland ponies.
It is caused by various things indirectly which then affect the liver, diarrea, gastro problems, foaling stress, any type
of stress, poor food, eating dead leaves, eating frosty grass, salmonella, being too fat, being given steroids, being given
most drugs, being given butte (No miniatures should ever be given butte for more than one or two doses). The list is endless
but the result is that these tiny horses have a very specific problem which is directly related to their smallness, they have
a very small liver which cannot tolerate any large changes in their blood..
When they feel poorly and stop feeding for a while their bodies switch to using body fat instead
just like other animals and humans, however in miniature horses this change happens to drastically. The fat goes into the
blood so fast that the ponies liver gets clogged up fast and when that happens it fails quickly.
The first warning signs of hyperlipeamia are on finding a pony that is down in the
mouth, lackluster, no spirit, not eating properly, messing about with their food but not eating. In the later stages the pony
will not eat at all even when being force fed, often they will not drink although some drink well. Usually these ponies do
not respond to any treatment although we have found that getting a vet to infuse glucose mix into the pony can reverse the
fatty blood quickly when it has been caused by a quick stress ie: foaling.
In the later stages of hyperlipeamia the pony will not want any food or water, it will be grinding
its teeth and trying to eat dirt of the floor, it will sometimes try to drown itself in a water trough, all in all it is very
distressing to see a pony at this stage. It is best to have the pony put to sleep before this stage but it is very difficult
when the pony is still maybe walking around. If you see the pony pulling its front feet up to its belly it is obviously in
great pain, this is the time to call in the angels if not before.
Our best advice would be that on finding a pony that is not wanting to feed in the stable, to put it out on grass
even in the winter but to also supplement its feed, put another couple of healthy ponies with it because this will encourage
it to keep eating grass.
We have recently had a
bad period where we had several poorly ponies, who seemed to be getting the same symptoms of Hyperlipeamia but we seem to
have pulled them through by throwing them back out into the cold field,s and supplementing there feed morning and afternoon
with Spillers Mare and Young Stock Mix, 1 scoop per pony morning and night. We have used Dodson & Horell Mare & Young
stock mix for years but this year none of the foals wanted to eat it. This is interesting, please comment if you have any
further views.
2008 Winter has been a bad year for
Shetland breeders, please email me with your experiences this winter so that we can all find the best ways to look after our
tiny equines in the future. Our vet has told us that he has put many shetland's to sleep this winter in our area due to
Hyperlipeamia.
Horses Live On Protein Not Grass
Our Vet asked me what do horses live on, I said grass and hay etc. he
said no, they live on protein which is produced in the processing of the food that they eat, this is recovered from their
colon at the end of the stomach process. It is all about bacteria in the gut and the colon of the ponies being in balance.
If something goes wrong with this balance it often causes diorrea We asked him if there is any product that could help to
add back the damaged bacteria to correct the balance. He told us of a few but then told us that the best way to get the correct
bacteria back into the pony is to feed it some of another healthy horses droppings. This is what new born foals do, they eat
mums droppings. It seems bad but our vet explained that the ponies droppings are just processes grass or hay which includes
the important bacteria just like Actimel for humans..
When
a pony wont eat we have found a good way to help them, we get a 20mm syringe and cut the whole end off so that it is just
a plunger, we wrap some tape around the first inch of the plunger so that it does not get stuck at the end. Then we mix a
very simple mix of oats-so -simple or readybreak with grass nuts and lots of sugar and some boiling water. When cool the mash
is semi solid and sticky. We then go to "force" feed the pony. We pull the whole plunger out off the syringe and
then keep stabbing the syringe into the paste until it is nearly full, then we put the plunger back in and carefully insert
it up into the poorly ponies mouth and then press the plunger. Hey-Presto the sticky mush gets chewed on and swallowed. Sometimes
we help it down with a squirt of sugar water.
Sometimes
we add droppings to this easily by just plunging the syringe into some fresh dropping. We then add sugar water to help the
pony to accept the food.
Please do not be afraid
to try adding bacteria back into your poorer ponies from better ones when they become poorer than the rest. It is only like
humans drinking actimel.
There is also another very
important lesson for breeders here and that is to not clear up mums droppings to quickly when she has foaled as the foal needs
this bacteria to make her gut work.

Eye Ulcers
Eye ulcers can occurs occasionally in horses, the first symptoms are the forming of a white area
somewhere on the eye, this is dead or damaged tissue. Horses eyes are very good at healing. As the eye starts to heal lots
of new blood cells will form to bring oxygen to the damaged area, this is called NeoVascularization. At this stage the eye
can look very bad, being very blood shot and milky. It is best to treat the eye twice a day with Chloromycetin 1% Ophthalmic
Ointment. The ulcers will usually clear up after a few weeks sometimes leaving a little blemish.
