Winter Colic: Why It Spikes, How to Prevent It, and What To Do If It Happens

Published

on

Colic is not a single disease. It’s a broad term for abdominal pain that can range from mild gas discomfort to a surgical emergency. Winter is a time when colic cases tend to climb, and for good reason: cold snaps change how horses eat, drink, and move. For owners in Oklahoma, where one blue-skied day can turn to ice the next, paying attention to water, forage, and routine can prevent a scary midnight call—and speed help if one is needed.

Why Winter Raises Colic Risk

Reduced water intake. Horses drink less when water is icy or hard to access. Even a modest drop in intake dries the gut contents and sets the stage for impaction colic. Horses prefer lukewarm water; keeping tanks ice-free and palatable matters.

Diet shifts. Winter often means a move from fresh pasture to more hay and, on some ranches, added grain. Forage changes alter moisture content in the manure and the way feed moves through the hindgut. Abrupt diet changes and drier rations can increase colic risk. Transition feed gradually and favor consistent forage.

Less movement. Ice, mud, or pen rest can cut turnout and routine exercise. Movement is a natural driver of gut motility. When horses stand more and walk less, the intestinal tract can slow, especially if they are also drinking less and eating a different hay.

Management hiccups during cold snaps. Frozen hydrants, unfamiliar hauled water, and changes in feeding locations are common Oklahoma winter headaches. Even small shifts—a different water source taste, moving hay from pasture to a sandy lot, or a sudden jump in concentrate to “keep weight on”—can add up to trouble.

Other contributors. Dental issues, heavy parasite loads, and sand ingestion (if feeding on bare, sandy ground) don’t take a holiday in winter and can compound risk. Keep those basics current year-round.

Prevention You Can Put to Work Now

Make water easy and appealing.

Keep every trough and bucket ice-free and clean. Aim for palatable, lukewarm water—many horses drink more when water is 40–65°F. Drop-in heaters, insulated tanks, and protected cords are simple investments that pay off. Check twice a day, more often in a deep freeze.

Salt to drive thirst.

Provide plain, loose salt or a white salt block at all times. Most horses won’t overdo it, and a little extra sodium helps stimulate drinking in cold weather. If your vet approves, adding a small amount of loose salt to feed during cold snaps can help.

Keep forage consistent and high quality.

Choose a clean, mold-free hay and stick with it. If you must change hay, blend the new with the old over 7–10 days. For easy keepers or older horses with marginal water intake, soaking hay or offering a soaked beet pulp mash can add moisture to the diet.

Go slow with concentrates.

Avoid big jumps in grain to “warm them up.” If extra calories are necessary for body condition, increase gradually and split into several small meals. Sudden concentrate increases are a recognized colic risk.

Encourage movement.

Turnout is your friend. Even a few hours of relaxed walking in a paddock helps gut motility. If weather limits turnout, add hand-walking or controlled exercise on safe footing.

Feed off the sand and keep lots clean.

Use mats, feeders, or sacrifice areas with footing to reduce sand ingestion. Sand burdens can smolder all winter and show up as colic when drinking drops.

Stay on top of dental and deworming.

Poor chewing leads to larger, drier feed particles and impaction. Keep up with dental checks. Follow your veterinarian’s parasite control plan; a winter larval “bloom” in some situations can add risk.

Mind routine.

Horses thrive on predictable schedules. Keep feeding and turnout times steady, even when the weather is ugly. If your water source changes—say you’re hauling water—some horses drink less until they accept the new taste. Monitor intake closely in those periods.

Know the early signs.

Pawing, looking at the flank, getting up and down repeatedly, reduced interest in feed or water, less manure, loose or very dry manure, reduced or absent gut sounds, sweating, elevated heart rate, abnormal gum color, or depression are red flags. Treat any abnormal behavior as a warning sign.

If You Think Your Horse Is Colicking: A Step-by-Step Plan

1) Call your veterinarian immediately.

Do not “wait and see” through a winter night. Many colics are time-sensitive, and early treatment is often simpler and less costly. While you wait, gather useful information.

2) Do a quick, safe basic check.

Note attitude and pain level. Count heart rate and respiration, take a rectal temperature if it’s safe, listen for gut sounds, and look at gum color and moisture. Share these findings with your vet; they help triage the case over the phone. If the horse is in severe pain or thrashing, prioritize safety and keep them from injuring themselves until help arrives.

3) Remove feed.

Pull hay and grain. You can offer small sips of clean, lukewarm water unless your veterinarian advises otherwise.

4) Walk, don’t work.

Light hand-walking can reduce rolling and may stimulate motility for very mild gas colic, but never exhaust a painful horse or “work it out.” If walking increases distress, stop and wait for your vet’s instructions.

5) Keep them warm and safe.

Wet or shivering horses burn energy and may drink less. Use a dry blanket if the horse is cold or wet and standing quietly. Avoid deep bedding or slick aisles that encourage rolling.

6) Don’t medicate without guidance.

Avoid giving painkillers, mineral oil, or home remedies unless your veterinarian instructs you. Pain meds can mask symptoms your vet needs to evaluate, and oral products are not appropriate for every colic type.

7) Prepare for transport if advised.

If referral is recommended, have a safe, ready trailer and a plan for winter roads. Keep your horse’s Coggins and paperwork handy to avoid delays.

Practical Checkpoints for Cold Spells

Trough audit: Before a front, test every heater and replace worn cords. Have a plan for hauling water if hydrants freeze.

Intake logs: In deep cold, jot down approximate daily water levels and manure output. A sudden drop in either is a warning sign.

Hay stash: Keep at least a week of the same hay on hand to ride out supply hiccups.

Contact sheet: Tape your vet’s number to the feed room door along with barn directions and gate codes for anyone helping in an emergency.

Winter colic prevention hinges on three controllables: water, forage consistency, and routine. Keep water ice-free and appealing, transition feed gradually, encourage movement, and watch for the subtle changes that signal a problem. If your gut says something is off, call your veterinarian and act. Quick recognition and prompt care save horses.

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.

Fly Control That Works: What’s Worth Your Money This Summer

Published

on

By Ann Asher

Every year about this time, it feels like the flies start winning. No matter how clean I keep the pens or how many fly strips I hang, they show up in clouds. Over the past few summers, I’ve tried just about everything—feed-through supplements, predator bugs, DIY traps, and plenty of fly sprays. Some things helped. Some were a waste of money. If you’re battling flies this year, here’s what’s actually worked for me—and what research says can make a real difference on the farm or ranch.

Start with Cleanliness (But Know It’s Not Enough)

The first—and most repeated—advice is to stay ahead of the mess. Manure management is critical, especially around barns, pens, and loafing sheds. Flies lay eggs in fresh manure, and those eggs hatch into larvae in as little as 24 hours during warm weather.
I try to clean high-traffic areas at least every other day, but the truth is, even on the cleanest farms, flies can still be a problem because of moisture, standing water, and nearby neighbors.

Feed-Through Fly Control: A Solid Foundation

One thing that made a noticeable difference for my horses and cattle was starting a feed-through larvicide early in the season. These products add a growth regulator to the feed that passes through the animal and prevents fly larvae from developing in manure.
It’s not an instant fix—you won’t see fewer flies for several weeks—but once it kicks in, you’ll notice fewer new flies being born.

Tip: Feed-through products only work if all animals on the property are eating it consistently. Otherwise, you’re just treating part of the manure, and flies will keep breeding.

Fly Predators: Small, Mighty, and Surprisingly Effective

Last year, I tried fly predators for the first time. These are tiny, non-stinging insects that lay their eggs in fly pupae, stopping the next generation.
I was skeptical (and honestly a little creeped out at first), but I noticed that where I used predators around the barn and dry lots, the fly pressure dropped. Some companies even offer subscription services that send predators timed to your local climate.

Tip: Fly predators don’t kill adult flies—they stop future flies. So you still need to control the adults already buzzing around.

Good Old-Fashioned Fly Traps

In areas like the barn aisle and outdoor runs, nothing beats physical traps.
I like a combination approach:

  • Sticky ribbons and strips for indoor areas
  • Odor-baited traps placed away from livestock areas to draw flies away

Tip: Hang baited traps a good distance from barns or stalls. Otherwise, you’re luring flies right into your animals’ space.

Fly Sprays: Choose Carefully

Fly sprays are the first thing most of us reach for—and they do help—but they have limits.
For horses, sprays containing pyrethrins, pyrethroids (like permethrin), or natural oils tend to offer the best repellency. Even then, most sprays only last a few hours, especially if animals are sweating heavily.

Tip: Apply before morning turnout and again before evening if possible. Reapplication is important, especially after heavy exercise or rain.

Other Tools That Help

  • Fly masks and fly sheets — particularly those with UV protection, to protect sensitive areas like the eyes and ears
  • Fans in barns and run-in sheds — flies struggle to land in strong airflow
  • Automatic sprayer systems — an investment, but highly effective for larger barns

The bad news? There’s no magic bullet for fly control.
The good news? Combining several methods—manure management, feed-through treatments, predators, traps, and targeted sprays—can actually make summer bearable for you and your livestock.

At the end of the day, I figure if I can cut the fly population by half, I’ve already made life better for my animals—and a lot less miserable for myself.

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?”
