Handling excitable horses during turnout can be a challenge, especially for those that become aggressive or try to bolt when leaving the stall. Fortunately, modern protocols and safe sedation options offer a solution that improves safety for both horse and handler. In this blog, we'll explore the benefits of sedation, discuss the most commonly used sedatives, and provide practical advice for horse owners.
Why Sedation Helps with Excitable Horses at Turnout Time
Excitable horses pose significant risks when it comes to routine turnout, often requiring physical restraint from handlers. Sedation reduces not only the need for such restraints but also the overall stress and danger involved in the process. Unlike general anesthesia, which carries a higher 1.2% mortality rate, standing sedation is considerably safer with a mortality rate of around 0.2%. This significant reduction in risk highlights the advantages of sedatives that allow horses to remain on their feet.
How Standing Sedation Works
Veterinarians often administer standing sedatives like xylazine and detomidine "to effect" with rapid onset times of 3-5 minutes. This allows for a precise dosage that minimizes side effects, tailored specifically to the horse's breed, age, and overall demeanor.
Common Safe Sedatives for Handling Excitable Horses
Equine veterinarians prefer standing sedatives due to their excellent safety profiles and limited side effects. Let's explore the most reliable options available for equine sedation today.
Alpha-2 Agonists
This category includes xylazine and detomidine, which are well-known for their ability to maintain an upright form even when a horse is heavily dosed. These drugs provide quick sedation and reduce potential risks, although there's a possibility for rare but notable side effects such as choke if the horse eats too soon post-sedation.
Opioids and Their Synergistic Effects
When combined with alpha-2 agonists, opioids like butorphanol boost their calming effect, making them highly effective for turnout scenarios. While side effects such as slow heart rates or facial twitching may occur, they are usually mild and manageable.
Acepromazine: A Reliable Tranquilizer
Though traditionally viewed with skepticism due to possible priapism, acepromazine remains a smooth sedative option. In fact, the risk of priapism in stallions is as low as 1 in 10,000 cases, making it a reliable choice for most horses during turnout.
Utilizing Trazodone for Pre-Sedation Calming
An oral sedative, trazodone, offers an additional layer of calm before sedation, particularly useful for anxious horses. While it can slightly increase the amount of xylazine needed at induction, it's effective for preparing horses for turnout or even stall rest.
Dosage and Administration Basics
Veterinarians will tailor the dosage according to the horse's breed, age, and temperament. For instance, xylazine is often administered at a rate of 0.1-0.2 mg/kg IV for routines such as lameness exams. Geriatric horses require extra care to avoid deeper sedation, while foals may lie down due to the effects.
Sedative Type and Mortality Risk
| Sedative Type | Typical Use for Turnout | Key Safety Notes | Mortality Risk (Standing) |
|---|---|---|---|
| Alpha-2 Agonists (xylazine, detomidine) | Calms for safe pasture release | Rapid onset; rare choke/aggression | 0.2% |
| Opioids (butorphanol) + Alpha-2 | Enhanced calm, lower doses | Reduces excitement risk | 0.2% |
| Acepromazine | Mild standing tranquilization | Priapism risk: 1/10,000 | 0.2% |
| Trazodone (oral) | Pre-handling anxiolysis | May need more xylazine | Low, study-based |
Beyond Sedation: Best Practices for Handling Excitable Horses
While sedation offers immediate relief in handling excitable horses, building everyday trust and improving handling disciplines can significantly reduce the need for sedatives over time. Paired with equestrian supplements available at our Everyday Horse Vitamins & Supplements collection, these strategies help maintain a balanced, less anxious state for your horse.
Potential Risks and How to Minimize Them
Sedation is safer than ever, with the majority of anesthesia-related issues occurring during the recovery phase. However, risks such as paradoxical excitement and ataxia persist. It's crucial to conduct sedation in quiet environments and ensure that horses are lightly fasted beforehand to avoid issues like choke.
When to Call the Vet and Best Practices
When turnout becomes a daily struggle, consult with a veterinarian to determine the best sedation options for your horse. In doing so, you'll not only improve the experience for your horse but also simplify your daily routine. Once the vet assesses the situation, they can offer a customized plan that might include regular monitoring or minor training sessions.
Conclusion
Incorporating safe sedative practices with the guidance of a veterinarian ensures that your excitable horse remains calm and safe during turnout, enhancing both the horse's and handler's overall well-being. By adopting these practices alongside effective turnout and fly protection solutions, horse owners can transform a typically stressful situation into a more enjoyable experience.
