Temporohyoid Osteoarthropathy

Published

on

By Lauren Lamb, DVM

Temporohyoid osteoarthropathy, also known as THO, is a neurologic disease seen in horses. It is a rare disease, but when diagnosed and treated early in the disease process, a horse can make a full recovery. THO is caused by arthritis, inflammation or infection of the temporohyoid joint.

The temporohyoid joint is made up of the stylohyoid bone and the petrous temporal bone. The petrous temporal bone is on the base of the skull within the guttural pouch. The stylohyoid bone is connected to the hyoid apparatus, which is a series of bone in the horse’s throatlatch that suspend the larynx (voice box) and the tongue from the base of the skull.

The temporohyoid joint has a significant amount of movement when the horse chews or moves its tongue. Two cranial nerves run through the petrous temporal bone, cranial nerve seven and eight. The facial nerve (cranial nerve seven) is responsible for movement of the lips, ears, blinking of the eyelids and production of tears.

The vestibulocochlear nerve (cranial nerve eight) is responsible for helping the horse keep its balance, walk in a straight line and hold its head in a normal position. The exact cause for THO is unknown. One possible theory is inflammation or infection of the THO joint, which will cause degeneration of the joint.

Basic Wound Care for Horses: What Every Owner Should Know

Published

By

If you spend any amount of time around horses, you learn fairly quickly that bumps, scrapes, and cuts are almost inevitable. Horses can find ways to injure themselves in well-maintained pastures, clean stalls, and even while standing quietly at the fence. While some wounds are minor and heal without much trouble, others can become serious if they are not handled correctly from the start. Knowing how to assess a wound and provide basic first aid can make a real difference in both healing time and long-term soundness.

The first step in dealing with any injury is evaluating where it is located and how severe it appears. Wounds on the legs deserve particular attention. Compared to the body, the lower limbs have very little muscle or fat between the skin and critical structures such as joints, tendons, ligaments, and bone. Because of this, even a small cut can turn into a major problem if it involves deeper tissues.

Certain areas are especially concerning. Cuts on the front of the knee (carpus), the front of the hock, the back of the pastern, or around the heel bulbs are more likely to involve joints or tendons. Large, gaping, or bleeding wounds are usually easy decisions—those warrant a call to your veterinarian. Smaller wounds can be more difficult to judge, particularly when it is hard to tell how deep they go. If you are unsure whether a wound penetrates beyond the skin, it is best to contact your veterinarian before attempting home treatment.

Lameness is another important factor to consider, but it can be misleading. Some horses with fresh joint wounds may not appear lame at first, even if a joint is involved. Over time, however, infection can set in, leading to severe or even non-weight-bearing lameness. On the other hand, injuries involving tendons, ligaments, bone, or extensive soft tissue damage often cause immediate and obvious lameness. When a horse is suddenly very sore or unwilling to bear weight, more serious injuries such as fractures must be ruled out.

Being prepared is one of the best things a horse owner can do. A basic first aid kit kept in the barn or trailer allows you to respond quickly when an injury is discovered. The goal of initial wound care is simple: clean the wound, protect it, and prevent further contamination until healing begins or veterinary care is provided.

Most wounds are dirty when first found. Flushing away debris is far more important than applying medication right away. Clean tap water or sterile saline works well for this purpose. A mild antiseptic solution can be used, but it should always be diluted. Strong solutions can damage healthy tissue and slow healing. A good rule of thumb is to dilute antiseptics until the solution is a light tea color. Gentle cleaning is key—scrubbing aggressively can do more harm than good.

Once the wound is clean, a topical treatment may be applied if appropriate. For minor cuts and scrapes, a simple triple antibiotic ointment is often sufficient. These products are widely available and effective when used correctly. In areas where bandaging is difficult or impossible, spray-on products designed to protect wounds can help keep dirt and insects out while the surface heals.

Bandaging can be extremely helpful for many leg wounds. A properly applied bandage helps keep the area clean, provides support, and protects the wound from additional trauma. Basic bandaging supplies include non-stick pads, gauze, cotton or combine rolls, and a secure outer wrap. Bandages should be snug but never tight enough to restrict circulation. They also need to be checked and changed regularly to prevent moisture buildup and skin irritation.

Even with good first aid, it is important to know when to step back and call the veterinarian. Wounds that are deep, involve joints, produce significant swelling, or do not improve over a few days should be professionally evaluated. Your veterinarian can also guide you if you are unsure whether a wound can be managed at home.

Horses may be accident-prone, but prompt and thoughtful wound care goes a long way. A calm assessment, proper cleaning, and knowing your limits as a caretaker can help ensure small injuries stay small and your horse stays on the road to recovery.

Winter Water Solutions

Published

on

By

Winter brings its own set of challenges. For ranchers and horse owners, few are more pressing than keeping water available. Cold weather, frozen tanks, and ice buildup can cut animals off from the single most important nutrient. Cattle can survive on short pasture and horses can get by on hay, but without water, everything stops. Hydration affects digestion, body temperature regulation, and overall health. That’s why every winter, producers across Oklahoma and North Texas turn their focus to one essential question: how do you keep water flowing when the mercury drops?

The struggle against frozen water isn’t new. Generations before electricity, rural families learned to outsmart the cold with ingenuity and grit.

Chopping Ice – One of the oldest solutions was also the most labor-intensive: grabbing an ax or a bar and breaking ice daily. While effective, this method demands constant attention and becomes impractical during long cold snaps. Horses and cattle can quickly fall behind on intake if a rancher misses even a few hours.

Windmills and Groundwater – Traditional windmills pumping from underground aquifers often provided water that was warmer than surface tanks, since groundwater stays at a relatively stable temperature year-round. Many old ranches still rely on this method, though windmill upkeep is a challenge in itself.

Insulated or Buried Lines – Families learned to bury water lines below the frost line or wrap them with insulating material. That practice continues today, and it remains one of the most effective long-term strategies for preventing frozen pipes.

Floating Devices – Ranchers also improvised with floating logs, balls, or even old tires in stock tanks. The movement helped keep ice from sealing solid and gave livestock a space to drink. While not foolproof, the idea is still used in remote areas.

These methods show the persistence of rural people, but modern technology has added new tools to the fight.

Today, ranchers and horse owners have a wide menu of winter water solutions, ranging from simple add-ons to major investments.

Heated Waterers – Electric or propane-powered waterers remain the most reliable way to ensure animals never face ice. Available in tank heaters, floating units, or fully enclosed automatic waterers, they keep temperatures above freezing even during prolonged cold. The trade-off is cost: electricity bills can spike, and in rural areas, running lines to distant tanks may not be practical. Still, for barns, lots, and heavily used pastures, heated waterers are a standard tool.

Solar Solutions – Where electricity isn’t available, solar-powered heaters have gained traction. Panels run small heating elements or pumps, reducing reliance on grid power. Though initial costs are high, they provide independence and sustainability, especially in sunny but cold climates.

Geothermal Systems – Some operations use earth’s steady underground temperature to keep water from freezing. By burying lines or tanks and tapping into geothermal exchange, water stays at safe levels without heavy energy use. These systems are especially effective when designed into new construction.

Automatic Waterers with Constant Flow – In some cases, ranchers use systems that keep water trickling constantly. Movement prevents ice buildup, though it can waste water if not carefully managed. This method works best where water supply is abundant and low-cost.

Tank Additives – While chemicals are never recommended for human or animal safety, some producers use nontoxic dyes or floating covers to limit algae and ice. These are niche options, but they illustrate the creativity at play.

Practical Ranch Hacks – Many ranchers mix and match. Submersible de-icers paired with insulated tank covers, old truck hoods repurposed as windbreaks, or even placing tanks on south-facing slopes to maximize sun exposure can make the difference between usable and frozen water.

Why does all this matter so much? Because winter dehydration can have cascading effects. Horses, for instance, are prone to impaction colic when water intake drops. Cattle that can’t drink freely eat less feed, lose weight, and struggle to maintain body condition. Calves and older animals are especially vulnerable. Even wildlife around a farm benefits from accessible water sources.

Beyond animal health, reliable winter water reduces labor stress. Instead of breaking ice in multiple tanks at dawn and dusk, producers with dependable systems can focus on feeding, calving prep, or other winter tasks. In a season where daylight is short and weather unpredictable, those saved hours are invaluable.

Water is the lifeblood of the ranch, and winter tests every producer’s ability to keep it flowing. From chopping ice with an ax to installing solar-powered heaters, solutions have evolved, but the goal is the same: hydration without interruption.

For some, a floating log and a good bar might still get the job done. For others, investment in heated automatic waterers pays off every year. The choice depends on herd size, geography, and budget. What unites them is the understanding that winter water is not optional. It is essential, and it always will be.

The Calf Roping Capitol

Published

By

By Krista Lucas Wynn

            Every fall, calf ropers descend onto a southwest Texas town for the annual Cinch Roping Fiesta, in San Angelo, Texas. The roping event was held October 23-26 and is the longest running stand alone roping event in the nation. The weekend features calf roping, breakaway roping, team roping, steer roping, and double mugging.

            The fan favorite event is the invitational calf roping, featuring the top 30 of the Professional Rodeo Cowboys Association world standings, as well as five from a qualifying event held the day before. Bryce Derrer, of Portales, NM, dominated the competition by winning both go rounds and the average. He pocketed over $16,000 for his efforts.

            Tom Crouse, Blane Cox, Chet Weitz, and Tyson Durfey followed Derrer in the first round, placing second through fifth respectively. Zane Kilgus, Cody McCartney, Logan Bird, Cash Enderli, and Riley Webb rounded out the second go round. Previously featured NTFR calf roper and local cowboy, Hagen Houck, also competed at the roping fiesta for the first time.

Weitz, of London, Texas, bested the short go field, with a time of 9.6 seconds. Kincade Henry, Webb and Brey Yore rounded out the final round.

World champion, Webb, also roped against world champion and 10 time Wrangler National Finals Qualifier, Caleb Smidt, in a 12 head match. Smidt retired in 2025 but still hung with Webb up until a missed calf cost him time. After that, Webb stayed consistent to finish the match with a time of 197.1 seconds, a full minute and a half ahead of Smidt.

A fan favorite event has quickly become the legends match, presented by O-H Triangle Ranch, during the calf roping event. This year, WNFR qualifiers, Jeff Chapman and Ricky Canton went head to head on six calves. Canton was the returning champion but was bested by Chapman after a back and forth contest. Chapman finished with a time of 84.3 seconds, and Canton turned in a total time of 91.7 seconds.

With three full days of roping, a remodeled arena, and beautiful weather, roping fans of all ages and disciplines had something to watch. Winnings for the calf roping and steer roping will count for the 2026 PRCA world standings. For full results, visit www.sanangelorodeo.com.
