A Mild Torsion of the Large Intestine
A blessed sight:  Matty eating!

A blessed sight: Matty eating!

It was perhaps an unsurprising way to get introduced to my new veterinary community.  Some might even say it was inevitable when moving nine ponies down in elevation by five thousand feet, over 300 miles, to new forage and water and management, that there would be something go awry.  That it took a week before I had a pony off her feed was what caught me by surprise.  I checked the ponies at sundown a week after we arrived at our new home, and Bowthorne Matty was laying down in the pasture visibly uncomfortable and occasionally rolling while everyone else was contently grazing nearby.  Fortunately, although it took 24 hours, Matty is once again doing fine.

After my first lines of defense in such situations didn’t instigate improvement (probiotics and Flunixin Meglumine), I called and introduced myself to the local vet who came highly recommended to me long before we arrived here.  Dr. Stevens is only fifteen minutes away, which is such a blessing compared to veterinary proximity in other places I’ve lived.  I transported Matty to the clinic at 7pm, and Dr. Stevens examined Matty.  She found a tight ring in her large intestine.  She tubed mineral oil in nasally and gave her additional medication and recommended I walk her until signs of improvement or otherwise. 

Matty did initially show interest in hay after we got home, and she did pass a small pile of manure while we were walking.  But then she lost interest in hay and attempted to lie down and roll while we were walking.  Dr. Stevens referred us to Sturgis Veterinary Hospital, about two hours away, so for the second time that night I loaded Matty and her son Willowtrail Ross in the trailer and we hit the road at 1:30am.  Neither Dr. Mez nor I were terribly awake when we greeted each other at 3:30am, but in time we developed a good relationship.  He examined Matty and ran blood tests and diagnosed Matty with a mild torsion of the large intestine.  He said that he did not consider her case to be urgent or dire and that he would keep her and observe her and keep me informed if she improved or if she would indeed require surgery to resolve the issue.  I was thankful for this wait-and-see approach.  When he also told me I wouldn’t be able to observe the surgery (due to insurance coverages), I headed for home.  After feeding the ponies in the corral, I went to bed at 7:30am after a 24 hour day, arising again at 1:30pm to find a message from the vet clinic.  Matty was eating and passing manure and able to come home.

Red lines show the extent to which Matty was bloated with gas at her worst.

Both Dr. Stevens and Dr. Mez asked me if Matty was bred.  Now I know why:  torsions of the large intestine are most common in pregnant broodmares.  They are thirteen times more likely than stallions or geldings to be afflicted with this problem.  While Matty is not bred, the at-risk period for broodmares extends to 120 days post-foaling, and Matty is just at the end of that window.  Preventive measures include slow changes in management, regular access to fresh water, and consistent feeding routines. (1)  All of these were challenged during our transition to our new home, added to which Matty is the head mare and may have felt additional stress about caring for her herd in our changed situation.

While we were observing Matty, Dr. Mez asked me if she was usually as round as she looked that early morning.  My answer was a guarded no; the mares all do look rotund this time of year after being on pasture, but Matty’s shape looked unusual to me.  Seeing her now, as shown in the photograph that looks to Matty’s rear from overhead, it’s clear how unusually shaped she was.  The red lines indicate how distended her loin area was with gas.

I am very thankful to Dr. Stevens and Dr. Mez for their care of Matty.  And I was flattered when the staff in Sturgis asked if I had a Fell Pony stud at home because they had a client with a mare who might be interested in breeding to him!

I Under-Estimated Them

It wasn’t until I put the second pony on a transport that I realized it, and even then it took a few days more.  A sudden change in my life had caused me to need to rehome four ponies quickly.  Two of the ponies I delivered myself into the hands of their new owners.  It was the other two that I delivered to a third party that showed me so much.

190417 Torrin departure5.jpg

When I parted with those two ponies, I was in tears.  One had shared life with me for nineteen years, and the other for thirteen.  We had done a lot together, and I considered them friends.  It’s normal for me to cry when I say good bye to a pony.  This time, though, was different, as these two showed me.  Neither of them would look at me as I said my final good bye.

I try hard to never be angry around my ponies or to have an argument with another person around them.  Over the years, they’ve shown me they don’t like that emotion.  Research has indeed shown that equines respond differently to happy and angry faces.  “Psychologists studied how 28 horses reacted to seeing photographs of positive versus negative human facial expressions. When viewing angry faces, horses looked more with their left eye, a behaviour associated with perceiving negative stimuli. Their heart rate also increased more quickly and they showed more stress-related behaviours.” (1)  One researcher said, “It's interesting to note that the horses had a strong reaction to the negative expressions but less so to the positive.”  I certainly have perceived that difference in response with my own ponies.  They are much more reactive to negative stimuli than positive.

The tears I shed as I said good bye were not angry ones, though, so I didn’t think the ponies would be affected.  I was wrong.  My tears were full of grief, heavy with emotion.  I underestimated these two ponies and the effect my emotions had on them.  One transporter later told me that the pony in their charge perked up after 24 hours.  The other was labeled a hard traveler, and it took her even longer to come around.  These ponies did react to my grief, and if I could apologize to them, I would. Next time that I am emotionally heavy when saying good bye, I will try harder to make it easier on my departing pony friend.

Wormers and Gut Microbiota
180822 Matty bringing up the rear horizontal.JPG

Many years ago, I was told by my vet to worm carefully if I ever expected that the worm load was high in a particular pony.  He had seen a yearling killed after being suddenly and heavily dewormed; he said it was because the worm burden was too high for the equine to safely eliminate.  I have never taken worming lightly since.  New research sheds light on the interaction between worms, gut microbiota and inflammation. (1)  Reviewing the research gave me new perspective on my vet’s sad story.

The research was conducted in Ireland and studied two different equine populations:  a group of yearlings and a group aged 1 to 7 years.  Two different wormers were used in the study, though only minor differences in results were observed between the two wormers.  There were differences observed, however, in the different, though not rigorously different, age groups.

The major finding of the study was that use of chemical wormers changes the diversity and abundance of the gut microbiota and causes changes in inflammatory markers.  The study recorded the gut microbiome characteristics at Day 0, Day 7, and Day 14.  The reduction in diversity and abundance at Day 7 was resolved by Day 14.  Both groups also showed changes in inflammatory responses from Day 0 to Day 7.  In both groups, the inflammatory responses were resolved by Day 14. The inflammatory responses were both local and systemic. 

The two groups of equines in the study had different microbiome populations, which the researchers attributed to both age and differences in environments.  Also, “The greater magnitude of changes seen in Group 1 compared with Group 2 may reflect a greater malleability of the still-developing gut microbiome in the younger horses, and/or greater numbers of animals in the former.”

I had always been told to treat worming as a medical procedure that required supportive therapies to be effective.  Probiotics in particular to restore the gut microbiome were recommended, and this study makes it clear why.  It takes up to two weeks for the gut to get back to normal after worming, so asking our equines to continue working during this period without therapeutic support is likely taxing to their systems.  Supporting broodmares seems to be especially important according to related research.

In their paper, the researchers suggest several interesting ideas.  First, that further research like theirs is easy to conduct because small strongyles are ‘ubiquitous’ in equines, with the worms possibly being present as adults but certainly as encysted larvae that can live up to 3 years in the intestinal wall.  This perspective supports the idea that we as equine owners are charged with controlling parasites in our animals rather than getting rid of them entirely.  The researchers then go on to suggest that worms may play a role in responses to inflammation in horses, so there may be opportunities to put them to beneficial use.  Eradicating them completely, then, may not always be in our equines’ best interest.

When I think back to the sad story told by my veterinarian, it’s clear why a young heavily infested horse might adversely respond to deworming, especially if not supported therapeutically.  I have always considered the probiotics on my shelf to be my jug of gold, and this research supports that valuation!

Apple Seeds

After I eat an apple for breakfast, I divide the quartered core between the ponies.  It hadn’t ever occurred to me that there might be a problem with this until I read the headline, “Are Apple Seeds Bad for Horses?”  It took me a few days to get around to reading the article, so I kept wondering what I would learn.  Also, I have an end-of-year holiday ritual called ‘wassailing the ponies’ that includes feeding apples to my ponies, so I was very curious if I could safely continue the ritual.

Wassailing Madie in 2017

Wassailing Madie in 2017

It turns out that apple seeds have a very small amount of cyanide in them.  That fact was the inspiration for the article whose headline I saw.  The author concluded that it would take a dose of upwards of 270 apple seeds to harm a 200 pound human, so a vast number to harm an equine.  Most apples contain 20 seeds or less, so it’s very unlikely that a human or equine could suffer adverse consequences from apple seeds under normal circumstances.  Other fruit pits are more problematic, including peaches, plums, and apricots – more for their fibrous nature than the cyanide they contain.  (1)

So I will continue my habit of sharing my breakfast fruit with my ponies, and I will continue my wassailing ritual.  The ponies and I will all be happy!

Early Winter, Late Spring, and Wood Fences
Wood chewing isn't exclusively reserved for fences.  Some pony has worked on this fallen lodgepole tree.

Wood chewing isn't exclusively reserved for fences.  Some pony has worked on this fallen lodgepole tree.

I thought I was the only one.  I thought it was just my ponies that, all of a sudden and seemingly without reason, would start ravenously chewing on our wood fences.  Then I read an article in Equus magazine (1), and I learned I’m not alone after all!  Of course the ponies do have their reasons for this behavior.  It’s my job to find out what those reasons are and if there is anything I can do to stop their destructive behavior.  I was hoping the article in Equus would have some clues.

My first fence chewer was my second pony.  He was just two years old and had been living in a herd in a large rough pasture before coming to me to live solo in a much smaller paddock.  This was before I had learned the advantages of companionship.  To redirect his destructive behavior, a friend suggested cutting willow switches for him to chew on instead, which I did for several months until he settled into his new life’s routine.  Occasionally, though, he will chew on wood still, so I knew that I had more to learn.

I was once so desperate to redirect one pony's behavior that every evening I harvested willow switches for him to chew on.  Yes, the goats often got some, too!

I was once so desperate to redirect one pony's behavior that every evening I harvested willow switches for him to chew on.  Yes, the goats often got some, too!

Next I began researching and addressing possible causes for the behavior.  I first ruled out cribbing because it is definitely wood chewing; it doesn’t have the air intake characteristic of cribbing.  Dental issues are another possible reason for wood chewing, but that didn’t explain the behavior I was seeing either.  Then I thought it was a nutritional issue.  Some sources suggest that wood chewing is a phosphorus issue, and indeed sometimes the chewing would start when the ponies had run out of their loose, free-choice minerals that contain phosphorus.  But the wood-chewing would sometimes happen when they had plenty of minerals.  Other sources suggest that it is a copper issue.  I have indeed seen less wood chewing since I started the entire herd on a regular copper supplement.  But the wood chewing didn’t completely end.

Then I returned to the idea that it’s a behavioral issue.  Indeed one pony in particular is hardest on the fences when I am gone for most of the day.  Perhaps it’s boredom after he’s cleaned up all the hay I put out for him.  Perhaps it’s anxiety about my absence.  But there are times when I’m gone and he doesn’t work on the fences at all. 

To protect my fences from being damaged, I looked into ‘paint’ that could be applied to make the rails unpalatable.  I didn’t like any of the commercial products available, so I devised a mixture of neatsfoot oil and cayenne pepper.  When I treat the rails with this mixture, the ponies will no longer chew on the rails.  It doesn’t of course address the underlying issue, whatever that issue is.

I was hopeful that the article I saw in Equus would have a solution to my fence gnawing problem.  I guess I can take some solace that it didn’t have any explanations beyond what I’d already considered.  What I did learn, though, is that studies have found that the behavior is typically during cold wet weather, “perhaps because of an instinctive urge for more roughage as temperatures fall.”  (2)  We have cold weather all winter here, but most of the time it’s quite dry (think powder snow that is coveted by downhill skiers.)  It’s in the late fall and early spring that we have wet snow and cold, and indeed that’s when fence chewing is at its worst here.  I tend to think the ponies are, in the fall, grieving the end of the grazing season, and in the spring, pining for the start of the grazing season!  This at least gives me a possible behavioral motivation.

I did run across one explanation elsewhere that was illuminating.  It turns out that lodgepole pine is higher in phosphorus than other woods, and equines will often choose to chew on lodgepole fences before other types of fencing.  My fences are built exclusively of lodgepole, so I haven’t seen this selective chewing.  It did make me wonder, though, if perhaps the ponies need even more phosphorus than they can get out of the minerals I make available to them. 

After seventeen years, my wood fences are in need of being rebuilt.  Because our lodgepole forests have been decimated by a beetle epidemic, wood fencing materials are a little more scarce than they once were, so I’m slowly replacing the wood fences with metal.  I’ll be glad that the new fences won’t be destroyed by chewing, but I’ll remain mindful that the ponies were chewing for a reason, and I need to make sure they have ways to address their needs.

Ponies and Food and Work
0307_MRRSkiddingBrush small.jpg

The title of an article about some new research read “Fat Ponies Will Work for Food.”  Ponies being in the title certainly caught my attention.  And I’m thrilled that ponies are meriting the attention of researchers.  I was, though, disappointed at the implied surprise that ponies are willing to work.  Ponies of course have a long and storied working history.  Nonetheless, I read the article to learn what the researchers had found.

Researchers in Australia constructed a feeder that had two sides with sliding doors.  Overweight ponies were given access to the feeder, and after consuming a small amount of hay, the door was automatically closed on one side and opened on the other.  The ponies had to walk around the feeder to access the other door.  The feeder design resulted in 3.7 times more distance traveled per day.  It also resulted in a decrease in body condition score, a decrease in cresty neck score, and a decrease in body fat percentage.  That’s all obviously really good news.  For those ponies that were food motivated, the feeder design also resulted in improved insulin sensitivity, also good news. (1)

Keeping weight off ponies who aren’t in regular work is a challenge for all of us.  Melody de Laat, PhD, BVSc, of the Queensland University of Technology, in Brisbane, said, “Low-intensity exercise of enough duration can be difficult to achieve in ponies that are not ridden regularly, if at all. The dynamic feeder enables a pony owner to exercise their pony without longeing or walking the pony.”  de Laat added, “If owners don’t have access to a dynamic feeding system they could consider walking their pony by hand—just bring him along on the daily dog walk.”  (2)

A quick internet search suggests that a dynamic feeding system isn’t readily available, but there are other ways to get ponies to do low-intensity exercise on their own.  I have had great success feeding on a track system (click here and here for articles on the subject.)  In the Australian study, they got the ponies to walk for two hours twice daily.  My track feeding system has the ponies walking one hour four times a day.  And while the researchers found benefits to physical health, I have also found that the increased movement has benefits for mental health.

Although the title of the article wasn’t entirely accurate – the ponies walked for their food, they didn’t work for it - the title did do the job of enticing me to read further.  And the research expanded my appreciation for the benefits of getting ponies to move on their own.  It is so important for both physical and mental health that ponies move in the course of their day, either through work or being encouraged to do so otherwise.  Anything that can help owners help their ponies with that objective is helpful indeed.
