The Ins and Outs of Colic in Horses

Published

on

By Garrett Metcalf, DVM

The horse’s gastrointestinal tract has been plaguing owners and veterinarians for centuries, causing long nights of endless worrying, fear and financial strain. The gastrointestinal tract is far from perfect in horses, but we have come to understand it much greater in the past few decades, leading us to be able to treat and prevent colic with much greater success. There are many causes of colic in horses with some avoidable and some that are not. Colic is a very broad overarching term that simply indicates abdominal pain and is not a diagnosis but rather a symptom. This article will discuss the key aspects of colic in horses, treatment methodologies and ways to avoid colic.

Prevalence of Colic

If you are a horse owner and haven’t experienced colic before, consider yourself very blessed. There will be a time when just about every horse owner will have a horse colic. According to data from the USDA, the incidence of colic published in 2001 was 4.2 events/100 horses per year. In previous studies, the findings ranged from 3.5-26 colics/100 horses per year. The incidence of fatalities from colic was 11 percent, and the overall percentage of horses that required surgery was only 1.4 percent. Demographics play a role in the types of colic that horses experience. A short list of these factors is types of hay available, weather patterns and breeds in the area that affect the types of colic seen in a given region.  Gender and use of horse is not a factor for colic, but horse breed is a factor and certain breeds have higher previous of certain causes of colic. The key point to remember is that the majority of colics respond to medical treatment that is usually provided by owner’s primary care veterinarian, but there are a low number of horses that surgery is required to correct the cause of the colic.

Trailer Safety Checklist

Published

on

By Janis Blackwell

As the season arrives to gear up for participation in your equine event of choice, one thing remains a constant for all horse owners. That constant is our responsibility to insure the safety of our horses by being diligent to maintain the integrity of the trailers in which we haul them. There are a number of things that can be dangerous both inside and outside of your trailer. Whether you traveled all winter long or whether your trailer sat unused or was used very little through the cold weather months, at least once a year your trailer is due a thorough going over. So here we go with a checklist that will help you insure a happy and safe trip for you and your equine partner.

  1. A sound floor is absolutely imperative. Whether your floor is aluminum, steel or wood, it should be cleaned regularly after use to preserve it. Urine and manure will erode and weaken all types of floors. Even rubber mats will not prevent erosion of your floor. (Maintenance tip: remove mats and wash aluminum floors often to prevent erosion.)
  2. Especially check wooden floors for rotten boards. Immediately replace questionable flooring before hauling. (Maintenance tip: For wood, remove mats and wash out manure and debris. Coat wooden floor in a cheap motor oil. Allow to sit in hot summer weather until the oil soaks in. Be careful—floor will be slippery until oil cures into the wood. This treatment yearly will preserve a wooden floor for much longer than normal as it repels urine and protects the wood).
  1. Keep the interior and exterior washed to enable you to check for rusted out places, leaks, etc.
  2. Have a professional check your brakes at least once yearly to be sure they are operating properly.
  3. Be sure tires are inflated to the proper air pressure, and check the inside of each tire for hidden unusual wear that could cause a blowout. Replace worn tires before leaving home.
  4. Wheel bearings must be checked and packed at least once a year. This should be done even if the trailer has been rarely used since the last time the wheel bearings were packed. In fact, trailer maintenance professionals say that sitting stationary and unused is even worse for the bearings.  Improper care and maintenance of wheel bearings can cause a wheel to seize up and actually twist off while in use. Use a horse trailer professional for this maintenance task.
  5. Axles should be checked for bowing. A bent or bowed axle can cause excessive tire wear and damage wheel bearings.
  6. There should be no more than two inches in height difference from the front of the trailer to the back. More difference than that causes the bulk of weight of the trailer and its contents to ride mostly on the rear axle causing it to bow and wear on both tires and wheel bearings.
  7. Another critical part of the trailer to keep an eye on are the butt chain or bar and the back door. The butt chain or bar should be firmly attached to the wall and its keeper and should always be latched. The door should have a strong secure latch with a pin to insure it stays latched while in motion.
  8. Finally, but certainly not of least importance is a thorough check of the trailer hitch including ball and coupling. Keep the ball well greased. Periodically, check to see that the ball is still securely tightened and the latch on the coupling is working properly.

These few critical safety check points can save you money, stress and the wellbeing of your horse. Until next time, happy trails and safe traveling.

History of the Horseshoe Part 2

Published

on

By Laci Jones

With the saying, “Don’t reinvent the wheel,” Lee Liles, owner of the National Museum of Horse Shoeing Tools and Hall of Honor said the same could be said about the horseshoe.

“Nothing is really new in a horseshoe,” he explained. “It just seems to be a revolving circle.”

While the horseshoe has not changed, Liles said the title of the horseshoe specialist has. At some point over time, the horseshoer took on the name “farrier,” he added.

Certification

Horseshoers in the late 19th century needed to have a certificate issued by the Master Horseshoers National Protective Association. Liles said the association was like a union. If someone was caught without being a licensed member, they could be fined $400.

The color of the certificates wa­­­­­s different each year, making the certificates easy to identify when entering the blacksmith’s shop.

Other countries like Canada and Germany also required certification. Horseshoers in London in 1909 needed to carry a certificate with them at all times. The certificate was signed by the queen, Liles explained.

Mid-Century Trends

In the 1940s, 1950s and 1960s, all horses had heel caulks on their horseshoes.

“I can remember back in the 1960s we had a shoe we called ‘The Cowboy Shoe,’” he added. The Cowboy Shoe was beveled out on the inside to help shed dirt. Liles said a good cow pony on rough terrain requires a tougher shoe.

“If it weren’t for a horseshoer moving up [in rough country] there would never have been good cattle country,” he said. “He kept the horses sound from being on the rocks.”

He remembered when owners could get away with just trimming their ranch horses in the 1960s. “Getting into the 1970s, you had to put shoes on ranch horses,” Liles added. “Their feet weren’t as strong because the breeding changed their feet a lot.”

The Horse

“The life of a horseshoer is very short,” Liles explained, “especially this day and time more so than the old days.”

To give a time-life-history of the horse, 24 million horses were in the United States in 1915. By 1950, they were down to two million. Farmers began working with tractors and the workhorse phased out, he added. In the late 1950s and early 1960s, horses became luxury items, Liles explained. Owners used horses more on ranches and started horse shows and events.

“In 1965, there was a shortage of horseshoers because most were cavalry horseshoers or taught by somebody who was in the cavalry,” he added. Those horseshoers retired by the 1960s, and there was a need for horseshoeing schools.

Z-Bar Shoe

“Our shoe industry has changed dramatically since 1979,” Liles explained. “We’ve got so may good horseshoes on the market today that you hardly need a forge to heat them up to shape them.”

Liles said the industry now has front and rears in the patterns, which has changed horseshoeing. The Z-Bar shoe may have been patented in 1900 in New Orleans, but the shoe has become more popular in recent years. “It’s popular in our horseshoeing contests,” Liles explained.

The Z-Bar shoe is used on horses that have a bad quarter crack, he added. The shoe relieves the pressure and lets the swelling go down, and the bar distributes the weight in the foot. This is the only patent I ever seen south of the Mason-Dixon Line,” he added.

Current Trends

“Just in the last few years, we’re seeing horseshoes with multiple nail holes,” Liles added. “That is more than we’ve ever had.”

For 200 years in the United States, horseshoes have always had eight nail holes in the shoe. Now, 10 to 16 nail holes are in a shoe. “That’s a dramatic change,” Liles explained. “It gives [farriers] more of an option to where they can rotate the nails around if the foot gets bad, so it’s not a bad deal.”

Shoeing horses on the front end and not the back end is trending in the show horse industry, he explained. When asked why this is trending, Liles said one person started winning, and everybody started thinking it would help them win.

“It’s not always necessary to shoe the back end of a horse,” he said. “Most of the weight on a horse is carried from the front end with the weight of the horse’s neck and the cowboy.”

Marvin Beeman, DVM and educator for the American Colt Horse Association, told Liles how a horse farrier shoes a ranch horse depends on the biographical areas in which they live in.

“If you change your horse from one environment to another environment, it will actually change the growth pattern of the horse’s foot and start a groove around his foot,” Liles explained. “When you change that horse’s environment, the horseshoer can actually read it in his foot.

“That’s hard for a lot of people to imagine, but when you bring a horse from the east coast to the west coast, that’s a dramatic change for that horse.”

Different Materials

Liles said using different materials is a current trend among horse farriers. In the early days of horseshoeing, farriers used wrought iron. Today, most horseshoes are made using plain steel. However, the show horse industry uses a lot of aluminum and titanium.

“A pair of heavy walking horse shoes can cost $5,000,” Liles explained, “but it’s made out of tungsten.”

Plastic and rubber shoes have also become popular in recent years. Amish horses used on roads have horseshoes made of Borium. Borium is a texture that keeps the shoe from wearing out, but it can also have a negative impact on the road.

“If you drive around in Amish or Mennonite country and see a dip in the road, it’s from a horse going down the road,” Liles explained. “A lot of states like Pennsylvania and Ohio have funded projects trying to come up with a traction device horseshoe that will not hurt their asphalt and highways as bad.”

Glue-on shoes have come along after he was an active horse farrier. The dairy industry uses the glue-on shoes more than anybody, he added. Cattle are on water and concrete, and they can have a tremendous problem with foot rot. Liles said proper nutrition can help combat this disease.

“I’ve never seen many horse’s feet that I couldn’t nail a shoe on,” Liles said, “but, I see where they help a lot of horses today.”

History of the Horseshoe Part 1

Published

on

By Laci Jones

If it were not for the horseshoe and wagon wheel, the United States would not have been founded, according to Lee Liles. The owner of the National Museum of Horse Shoeing Tools and Hall of Honor said Oklahoma is the grandest example in the world.

Horseshoe books date back to 400 B.C. In fact, the oldest horseshoe at the museum in Sulphur, Okla., is more than 500 years old from Denmark.

“I don’t like going back much farther than 1860 because we don’t have the documentation to back it up,” Liles explained. “You got a few magazines like the Harper Weekly and the Wallaces’ Report, but you want to verify the facts.”

19th Century Patents
The first patent on a horseshoe manufacturing machine in the United States was issued in 1834 to Henry Burden, a Scottish-born industrial engineer. By 1850, Burden had more than 50 different patents on his machines at Burden Iron Works in Troy, N.Y., Liles added.

This was all before the first horseshoe nail patent, which was issued in 1863 to Daniel Dodge in Keeseville, N.Y. The horseshoe nail is the most difficult nail in history to manufacture, Liles explained.

“It’s got a lot of different tapers to it,” he explained. “The nail needs to be strong and durable enough to drive through a foot, come out, be turned over 180 degrees and clenched down in the horse’s foot.”

The nail industry has changed a lot throughout the years, Liles said. In 1853, the horseshoe nail was made from Swedish Iron, but copper nails have become popular in recent years. The oldest nail company left in the United States was the Capewell Horse Nail Company owned by the Mustad family. The nail company started in 1881, and they recently moved out of the country.

“All of these major shoe companies, tool companies and nail companies were located in the northeast United States,” he explained. “That’s where the population was. There weren’t any companies located down here in the South like Oklahoma or Texas.”

Horseshoeing Literature

Most information on horseshoeing actually came from Germany, Liles explained. German books were first written in 1861 by Leisring and Hardman. In 1882, Lungwitz was added as a co-writer.

“[Leisring, Hardman and Lungwitz] were the main vets at the Royal Veterinary College,” Liles said. “[Hardman] wrote his own first book in 1884 and wrote 24 editions. Nobody else has ever written that many books.”

Liles said books are the greatest assets for education. In 1866, the U.S. Congress adapted the cavalry books would be written on the Dunbar System.

“Alexander Dunbar was a person who our Federal Government paid to teach anatomy to horseshoers back in that era,” Liles explained.

John Kerman, who was running a horse shoeing school at Fort Carlisle, Penn., wrote the book written on the Dunbar System. The first American horseshoe book was written in 1871. In 1902, Kerman came to the shoeing school at Fort Riley, Kan.

“The cavalry has been the main source of horseshoers in this country up to the 1950s,” Liles said. “The Army technical manual, TM-220, has been the most copied horseshoeing book in history.”

In the 1890s, Pennsylvania State recruited Mississippi-native, John Adams as a professor. The university sent Adams to Germany to study under Lungwitz.

“When he came back in about 1896, he and Lungwitz were such good friends that he had permission to write the American edition of the Lungwitz book,” Liles explained. “When he came back, Adams brought an instructor from Germany to Penn State to teach anatomy and horseshoeing to the vet students.”

Even Cornell University and Michigan State University had a protégé of Lungwitz in 1913, Liles said.

William Russell

“We had a great educator in Cincinnati, Ohio, who wrote 15 horseshoeing books from 1879 to 1907,” Liles explained. “His name was William Russell.”

In 1887, the first shoemaking contest was held in Cincinnati, Ohio, where Russell won. “The contest consisted of making 100 shoes on an opry stage in front of 3,000 spectators,” Liles explained.

Russell made 100 horseshoes in two hours and 40 minutes with the help of a team. John Silk, who later became a famous horseshoer, was one of Russell’s competitors.

In the 1890s, many horseshoers, including Russell, created display cases filled with their horseshoes. Many of these display cases are still intact and hanging in the museum. One of the cases was in the World Fair in St. Louis in 1904.

“When it went to the World Fair, they added nails to the case,” he added. A photo of the case at the World Fair was added into one of Russell’s books, and it was one of the last display cases he made. Russell offered all of his collection for sale in the same year.

“He died in 1907,” Liles explained. “He was a sick man, and he was blind when he died.”

Aluminum Horseshoe

Liles also has a case located at the museum built in 1895 had an aluminum horseshoe inside. “That is very rare,” he said. “In that era, they only produced 65 pounds of aluminum per year. Aluminum was a precious metal, and you had to buy it through a jeweler.”

Liles said he does not think the aluminum held up well to wear and tear. William Wedekind received the title, “The World’s Greatest Horseshoer” at the 1892 Chicago World’s Fair. Wedekind even made an aluminum horseshoe in 1883.

“It was so light that it floated on water,” Liles explained. “They can’t duplicate the shoe today to make it float on the water.”

The Right Shoe

Liles said when people come to museum, they are used to dealing with one breed of horse and one discipline with the horse. The type of horseshoe used depends on the breed and the discipline. “In this country, we have roughly 400 different breeds of horses,” Liles said.

Liles said he was a horseshoer, which is a lot different from a cowboy shoer. For instance, a horse that is going to go trail riding or ranching needs a high-quality steel horseshoe.

A show horse will wear aluminum shoes because the aluminum will wear the toe quicker. “It will give him a quicker time to break that shoe in,” he added. “If your shoe isn’t new at the show, he has to get that shoe back to where it feels comfortable.”

Many of the plastic shoes are meant for horses that are on concrete, asphalt or wood. Liles said plastic shoes are commonly used in the circus.

A common misconception is people think the weight of the horseshoe affects a horse in either racing or working.  “They think plastic is so much lighter,” he explained. “If that is the case, why don’t you just ride him barefoot?”
