Umbilical Hernia

Published

on

By Lauren Lamb

An umbilical hernia is a defect in the horse’s ventral body wall at the location of the umbilicus. The umbilicus is the equivalent of our belly button. The umbilicus is where the umbilical cord attaches to the foal while it is developing in the mare’s uterus. The umbilical cord is made up of a vein, two arteries and the urachus. The umbilical vein and artery carry blood to and from the fetus as it is developing in the uterus. The urachus is a tube that connects to the fetus’ bladder and carries urine from the developing fetus.

Umbilical hernias are seen in foals between the ages of birth and three months of age. The hernia bump seen on the bottom of the abdomen is made up of skin, subcutaneous tissue, peritoneum (lining of the abdomen) and a piece of the gastrointestinal tract.

Questions concerning umbilical hernias frequently asked by owners:

  • How does an umbilical hernia develop?
  • Are they genetic?
  • How can I prevent an umbilical hernia?

Some evidence shows umbilical hernias may have a genetic component; however, the genetic influence is most likely mild. This means breeding a mare and/or stud that had an umbilical hernia when they were foals will not result in an offspring with an umbilical hernia. The flip side of the coin is also true; crossing a mare and stud with no history of umbilical hernias will not result in a foal without an umbilical hernia.

Some have a strong belief that foaling behavior of the mare immediately after delivery can have an influence on whether a foal will develop an umbilical hernia. The natural behavior of a mare following delivery of her foal is to remain lying down until the foal starts to move and becomes more active. This may take several minutes for the foal to become active. Once the foal becomes active, the mare will stand up and break the umbilical cord about one inch from the foal’s navel. When a mare stands prematurely, the risk of an umbilical hernia forming can be increased. The most common reason for a mare to stand prematurely is human intervention. When humans try to rush into the stall to assist the foal or mare, the mare will become nervous and stand up too early.

An umbilical infection can lead to an umbilical hernia. The post foaling care of the umbilicus can influence whether or not a foal will develop an umbilical infection. The umbilicus should be dipped in dilute Nolvasan solution or betadine solution two to three times a day for the first three days of life. An umbilical infection is likely to occur if the umbilicus is not dipped in an antiseptic solution for the first three days after birth.

The size of an umbilical hernia is measured in fingers, aka the number of fingers that will fit in the hernia. A small hernia is less than three fingers in size. A large hernia is anything bigger than three fingers in size. The hernia should not be painful on palpation, nor should there be any heat or swelling around the hernia. When you place your fingers in the hernia, the contents of the hernia should be easily reduced (pushed back into the abdomen). A veterinarian should be contacted as soon as possible if you notice any heat, swelling, pain on palpation or you cannot reduce the hernia. A veterinarian should also be contacted as soon as possible if a horse with an umbilical hernia starts to colic. All these clinical signs are evidence that a portion of the intestine is stuck within the hernia. When the intestine is stuck within the hernia, the blood supply to the intestine can be compromised, which will result in the intestine becoming necrotic—dead. The hernia should be checked daily to ensure none of the previously mentioned clinical signs have developed.

Several treatment options are available for hernias. One conservative treatment option for small hernias (less than three fingers), is to reduce the hernia one to three times a day. By reducing the hernia you allow the hernia ring (defect in the body wall) to heal close. When the foal reaches four months of age, there is little chance that the hernia will heal with conservative therapy. Any foal that is greater than four months of age with an umbilical hernia will need a surgery to repair the hernia.

An umbilical hernia has two surgical repair options—both require general anesthesia and can be performed in a clean stall or a surgery room. A hernia repair performed in a surgery room has lower complication rate following surgery.

The first surgical option is called the closed technique. With the closed technique, the abdominal cavity is not opened, but the skin and subcutaneous tissue are opened. The hernia is repaired by placing large sutures across the abdominal defect. The closed technique decreases the risk of an infection occurring within the abdomen, but it increases the risk that a portion of the intestine is sutured to the body wall. The closed technique is usually used in cases were the surgery is performed in a stall within the barn. In this location, there is higher environmental contamination compared to a surgery room.

The open technique is the second option. With the open technique the abdominal cavity is opened and large sutures are placed across the defect to close the hernia. With the open technique, the risk of the intestine being sutured to the abdominal wall are significantly decreased. The open technique should be performed in a surgery room.

Following surgery, foals are kept on stall rest with no hand walking for two weeks and then turnout in a small paddock or trap for an additional two weeks. After four weeks, foals are allowed to go back to regular turnout and exercise.

Umbilical hernias are abdominal wall defects that are commonly seen in foals. The cause of an umbilical hernia is not completely understood; however, both genetics and husbandry practice can contribute to a horse developing an umbilical hernia. Surgery is not always required to repair umbilical hernias unless the foal is over four months of age. At this age surgery is needed to repair the hernia. Following surgery, foals had a good prognosis.

From a Kid’s Horse Point of View – Western Housewives

Published

on

By Summer McMillen

As the land starts to thaw and cowboys and cowkids everywhere are gearing up for spring there is one specimen in particular that is dreading the coming season. And that is ponies. Or more specifically, kid horses.

Let’s look at life from the kid horses point of view for a second.they have the winter off. They’ve gotten to enjoy some much needed R&R in the back pasture. Their hair has gotten long and so have their hooves. They’ve spent the winter feasting on native grasses, alfalfa, and the occasional bucket of grain when it’s was especially cold.

They’ve gotten to wonder aimlessly while the real work horses were still being caught for essential tasks. The most work these kid horses have had to endure the last few months were being tied to the arena fence to get the cockleburs brushed out of their tail.

Yes, life has been calm for these kid horses. But, there is a season for everything and the season for being used and abused is fast approaching.

My own children all share a little pony they affectionately call “Rubble.” He is a certified welsh pony that is as tall as he is wide and is as passive as he is…not. They spend summers riding him bareback. And when they aren’t riding him bareback they are riding him fully saddled. Tiny little bit in his mouth being yanked in every which direction.

The little fellow takes everything in stride. But I can feel him starting to resent me from the back pasture already. Every time I carry him some feed he gives me a look that just screams “please keep all three of your children away from me forever please.” I laugh at him and tell him he doesn’t mean it and then he runs away as fast as he can. It’s a special bond.

Kid horses are funny like that. We entrust them with the lives of those most special to us. We saddle them up and throw the little cowkids on them and assign them small tasks like moving 200 pairs to a new pasture or, holding the herd while dad doctors wheat cattle. More often than not, the young partners get their job done. Sometimes in unlikely ways.

Last summer my daughter hopped up on Rubble bareback and was going to trot down the road and get our mail. A simple and harmless task I thought. I was proud of her for taking the initiative. I was also proud of her when I looked out the window, saw the little pony start crow hopping with excitement and the unassuming 8-year-old being catapulted in the ditch. Instead of crying she climbed back on. Tenacity, I thought. That’s what kid horses are good at teaching.

A few months later I was watering all our geldings. The three kids whom I raised, better known as the three amigos, were all harassing the little pony. My youngest son decided it was his turn. He climbed up on Rubbles back as proud as a peacock.  But, he couldn’t help himself. He wanted to look that pony in the eye. So he starts leaning. Farther and farther until he leaned all the way to the ground. Lost a boot in the process. Instead of rushing to his side I waited for the tears. He was only two years old at the time after all. Instead his face was filled with glee. Joy, I thought. That’s what kid horses are good at teaching.

My middle boy is afraid of heights. So mounting a horse has been tough for him. When we introduced Rubble, I wasn’t sure he could even manage his height. After a little encouragement he donned his chaps, boots, and hat with a turkey feather in it and mounted the little horse. In a matter of five minutes the little cowboy had rubble trotting around the arena with his hand in the air and his spurs in his neck. (Gently of course.) Confidence builder, I thought. That’s what kid horses are good at teaching.

While, most of the time kid horses are a nuisance. Eating all our alfalfa and requiring special horse shoes to function properly.. they are more often than not a priceless gift. Teaching the ones we love most how to have tenacity, joy, and confidence.

While the ponies in our life may love their time off in the winter you can’t convince me that they don’t love their jobs in the spring. Even if it’s just a little bit. When that little cowboy shoves a bucket of grain in their face after a job well done together, the ponies head sits a little higher and so does that little cowboys hat.

Foot Abcesses in Horses

Published

on

By Garrett Metcalf, DVM

A foot abscess is a common occurrence in horses throughout the year, with wet weather often contributing to an increase in cases. These abscesses can cause significant pain, lameness, swelling, and overall misery, making it important to address them quickly and manage pain to keep the horse comfortable. There are various methods used to treat foot abscesses, and this article will outline techniques to evaluate and treat them as efficiently as possible.

A foot abscess is a localized or sometimes diffuse infection trapped between the sensitive and non-sensitive laminae within the hoof capsule. Abscesses may develop spontaneously due to everyday stress and environmental factors that allow bacteria to penetrate down to the sensitive tissues. Other causes include penetrating injuries to the sole from nails, sharp rocks, or even thorns. Poor hoof care and misdriven shoeing nails can also lead to abscess formation. Common sites include the white line, where the sole and hoof wall meet, and the bars of the heels.

The level of lameness caused by a foot abscess can vary, but it often results in visible discomfort at the walk and can even cause non-weight-bearing lameness. Swelling that begins at the foot and moves up the leg may occur, particularly if the abscess migrates and ruptures at the coronary band. These cases are often referred to as “gravel” abscesses, which are simply abscesses that find the path of least resistance and exit at the coronary band, creating a draining tract. In some cases, especially involving a hind foot, the horse’s movement may appear so abnormal that it mimics neurological issues, confusing owners and veterinarians.

Diagnosing a foot abscess begins with a lameness exam. Most affected horses will be visibly lame at the walk, though in some cases a trot may be necessary to detect the issue. Regional nerve blocks can help confirm that the pain is originating from the foot and not another part of the limb. Horses with abscesses often show an increased digital pulse and, occasionally, noticeable heat in the foot. The bounding pulse is due to inflammation and is most easily felt just above the hoof near the ankle. If the horse is shod, removing the shoe is often necessary for a thorough exam. Hoof testers are useful in identifying the most painful area, and horses with abscesses are typically reactive to pressure. Cleaning out the foot with a hoof knife is important for exposing any defects or tracts in the sole or frog. Often, a dark spot or line will lead to the source of the abscess.

There are multiple ways to treat an abscess, and opinions vary widely, but my preferred approach is to open the abscess as soon as possible. This provides nearly immediate relief for the horse and allows the infection to begin resolving. A sharp hoof knife or loop knife is a reliable tool to open the abscess and create drainage through the bottom of the foot. Allowing the abscess to drain from the sole reduces the risk of a gravel abscess and makes it easier to treat the area with topical poultices. After opening, it’s important to bandage the foot both to draw out remaining infection and to keep the area clean.

A large baby diaper makes a simple, effective bandage. It’s absorbent and fits the hoof well. Secure it with layers of Vetrap, duct tape, and Elastikon, or place the hoof in a medicine boot to keep it protected. Poultice choice is often based on personal experience and availability, but the goal is the same — to draw out infection and prevent contamination. Products like Magna Paste, an Epsom salt-based poultice, are effective, as is a homemade mix of sugar and Betadine. There are many other options, but whatever product is chosen should be safe and offer antimicrobial properties.

In some cases, an abscess may be difficult to locate or open. Soaking the foot in warm Epsom salt water can help soften the hoof and encourage the abscess to rupture or become easier to identify. Pain management is also helpful while waiting for the abscess to surface. If the abscess continues to recur or proves difficult to treat, radiographs can help evaluate the hoof’s internal structures. While most abscesses don’t show up on X-rays — since the fluid is the same density as the hoof — they may be visible if gas is present within the abscess. Radiographs are especially important in cases of puncture wounds, to ensure deeper structures like the coffin joint or navicular bursa aren’t involved. In cases of penetration, it’s best to leave the foreign object in place until X-rays are taken, which helps determine the extent of the injury and what structures may have been affected.

While preventing all foot abscesses isn’t always possible, good hoof care goes a long way. Regular trimming on a consistent schedule helps maintain healthy laminae and prevents stretching of the white line, which can allow bacteria to enter. Careful shoeing practices, including proper nail placement, can further reduce the risk of abscess development.

Foot abscesses are painful, frustrating, and often sudden — but with proper diagnosis, drainage, and aftercare, horses typically recover well and quickly return to soundness.

The Pull of the Barn

Published

on

When I was younger, I saw plenty of old Westerns. They were fun to watch, but one part always stressed me out. Inevitably, a cowboy would get shot or thrown from his horse, and while the cameras stayed on the fallen rider, I worried about the horse. Would it wander around lost on the prairie, never finding its way back? The truth is, most horses know exactly where home is. Turn one loose, and it will drift toward the barn. Ride one out, and the trip away from home feels steady, but the return picks up pace the moment the barn roof comes into sight. We even have a name for it: barn sour.

Horses are prey animals, and survival has always depended on familiar ground. For a domestic horse, the barn means food, water, and the company of the herd. Ethologists (scientists who study animal behavior) point out that horses are quick to learn patterns. When hay and grain appear in the same place every day, that spot becomes magnetic. Over time, repetition lays down mental trails as clearly as cattle wear down physical ones in a pasture. What appears to be stubbornness is actually instinct. The barn equals safety, and safety equals survival. Riders from cavalry days to modern ranches have written about horses quickening their pace on the way home. And though the land changes, that pull never does.

People are not so different. We all have barns in our lives — comfort zones we gravitate toward, routines that steady us. They serve a purpose. Like a horse standing at the gate, we lean on safe ground when life feels uncertain. But the pull can also hold us back. A horse that refuses to leave the yard never discovers what lies beyond the fence, and the same is true for us.

That balance shows up in history too. Old cattle trails once served their purpose, guiding herds north and helping to build economies. But when railroads and fences changed the landscape, those well-worn tracks became ruts. Progress required new paths. Our own habits work the same way. Some keep us grounded. Others only circle us back to where we started.

When I see my horses drifting toward the barn, I think less about impatience and more about instinct. They are drawn to the familiar, and so am I. The barn matters. It is the anchor point, the place of rest. But the pasture matters too, because growth is waiting outside the gate.

Those old Westerns had it right in at least one way. The cowboy’s horse was never going to wander off aimlessly. It would head back to camp, back to the barn. That simple truth still plays out in every pasture and arena today. Horses know where home is. The question is whether we will let the pull of our own barns keep us tied too tightly, or whether we will use them as a base to step farther into the wide-open ground ahead.
