Why Do Horses Crib? Examining a Unique Equine Behavior

Last updated: August 8, 2024

By: Miles HenryFact Checked

Cribbing, where horses bite on stable objects and inhale air, is more than just an equine quirk; it’s a significant indicator of their mental and emotional state. This compulsive behavior often signals stress or discomfort, necessitating a deeper understanding of equine care.

Beyond being a behavioral issue, cribbing can lead to serious health problems such as dental damage, weight loss, and gastrointestinal issues. In the U.S., approximately 4.5% of horses exhibit cribbing behavior, which equates to about 414,000 horses. Understanding the reasons behind this behavior is crucial for effective management and prevention.

With my experience managing a stable and dealing with a horse that exhibits this behavior, I’ve delved into the complexities of cribbing to provide essential insights for any dedicated horse owner. Join me as we unravel the mystery behind this age-old question: Why do horses crib?

Why Do Horses Crib?

Understanding the underlying causes of cribbing is essential for managing this behavior effectively. Below, we explore the key factors contributing to cribbing in horses.

Boredom and Lack of Stimulation:

Boredom and Lack of Stimulation: Horses are naturally active and social animals. When confined to stalls without adequate mental or physical stimulation, they may resort to cribbing as a coping mechanism, a behavior highlighted by research from the Ohio State University Extension and Extension Horses.

Stress and Social Isolation:

Stress and social isolation are significant triggers for cribbing. Horses, being herd animals, thrive on social interaction. When isolated or stressed, they are more likely to develop cribbing behavior. For more insights, see the recommendations from UC Davis.

Diet and Feeding Practices:

Modern feeding practices, such as feeding large grain meals infrequently, can lead to digestive discomfort, which may trigger cribbing. Adjusting the diet to include more forage and less concentrate, as suggested by the University of Minnesota Extension, can help reduce this behavior.

Genetics and Temperament:

Certain breeds, such as Thoroughbreds and Quarter Horses, have a genetic predisposition to cribbing. Additionally, horses with specific temperamental traits are more prone to develop this behavior under stress, as highlighted in studies from Houpt Lab.

Gastrointestinal Issues:

Horses suffering from gastrointestinal problems, particularly gastric ulcers, may crib to alleviate discomfort. Managing these underlying health issues is crucial in controlling cribbing behavior. For further information, refer to the National Institutes of Health.

Practical Health Management Tips for Cribbing

Managing cribbing effectively requires addressing the associated health implications and providing comprehensive care. Below are the key areas to focus on:

Dental Health:

Regular dental check-ups are crucial for horses that crib, as this behavior can cause significant wear on their teeth. Equine dentists can float teeth to maintain proper chewing function. Learn more about basic dental care from Extension Horses. Providing safe chewing alternatives, like toys, can also help redirect the behavior and minimize dental damage.

Weight Management:

Monitoring your horse’s body condition is essential, especially if cribbing has led to weight loss. Adjusting their diet with calorie-dense forage and providing frequent meals can help. The Equine Disease Communication Center offers additional guidance on maintaining a healthy weight in horses.

Gastrointestinal Health:

To prevent digestive discomfort, focus on a forage-rich diet and limit grain intake, as advised by the University of Minnesota Extension. Regular veterinary check-ups are also necessary to monitor and manage any underlying gastrointestinal issues.

Practical Management Tips

Based on insights from the Ohio State University article, here are some practical cribbing management tips:

• Environmental Enrichment: Increasing turnout time and providing mental stimulation through social interaction or toys can help reduce cribbing.
• Cribbing Collars and Tools: These can be used temporarily as part of a broader management strategy but should not be relied upon solely, as horses may adapt to them.

Personal Insights and Experiences

Owning a horse that cribs has been a challenging experience, and I’ve experimented with various methods to manage this behavior. Over time, I’ve used three different types of cribbing collars on my horse.

Each collar initially seemed effective, working for about two to three weeks. However, she eventually learned to crib even while wearing the collar, which made it clear that this wasn’t a long-term solution.

Without a collar, my horse tends to lose weight, making it essential to address the issue consistently. Through trial and error, I’ve found that turning her out into a pasture provides the most relief.

The increased time outside, with the opportunity to graze and interact with other horses, significantly reduces her cribbing. However, due to weather conditions and stable management constraints, I can’t keep her turned out all the time.

To mitigate this, I’ve worked on balancing her time indoors with other forms of environmental enrichment, such as providing toys and ensuring she has constant access to forage. Combining these strategies has helped me manage her cribbing better than relying on any single method alone.

This experience has taught me that managing cribbing requires a multifaceted approach, adjusting the strategy based on the horse’s specific needs and monitoring for any changes in behavior. This aligns with studies from UC Davis, highlighting the complex and persistent nature of cribbing.

If you have any experience with horses that crib, share them in the comments. Your insights may help others dealing with this issue in their horses.

By combining these health management strategies with practical tips, you can effectively manage cribbing in horses. Adjust your approach based on your horse’s specific needs and consult with professionals for the best outcomes.

Expert Insights and Research Studies on Cribbing

Gaining insights from experts and real-world cases is invaluable in understanding and managing cribbing. Here’s a summary of key research studies and expert opinions:

Research Studies on Cribbing

• Motivation for Cribbing by Horses: This study by K.A. Houpt reveals that horses’ motivation to crib is comparable to their drive for food, suggesting that cribbing is a high-demand behavior. Restricting this behavior could raise welfare concerns, emphasizing the need for careful management strategies (MyHorseUniversity, Equus Magazine).
• Cribbing and Salivary Secretion: A study investigated whether cribbing increases saliva production to reduce gastric acidity, particularly in horses with ulcers. The findings challenged the idea that cribbing helps manage gastric ulcers, as no significant increase in saliva was observed during the behavior (ScienceDirect).

Expert Opinions

• Carissa Wickens, PhD (University of Florida): Dr. Wickens emphasizes that stereotypies like cribbing are difficult to stop once they become habitual. She advocates for environmental enrichment and stress reduction as key strategies for managing this behavior (The Horse).
• Equine Behaviorist Insights: Experts recommend focusing on environmental enrichment, such as increasing social interaction and providing more natural grazing opportunities, to help reduce cribbing. These strategies align with the understanding that cribbing often serves as a coping mechanism for stress and boredom (HorseRacingSense).

Expert insights provide a foundation for understanding cribbing, but real-world case studies demonstrate how these strategies work in practice. Let’s look at some examples of how other horse owners have successfully managed cribbing.

Case Studies

• Case 1: Young Thoroughbred: A young Thoroughbred with a history of cribbing showed significant improvement after her daily pasture time was extended, and she was allowed more interaction with other horses. This case highlights the importance of socialization and environmental management in reducing cribbing behaviors.
• Case 2: Four-Year-Old Gelding: A four-year-old gelding’s cribbing behavior decreased after his hay ration was increased and a large ball was introduced into his stall to combat boredom. This case underscores the value of dietary adjustments and mental stimulation in managing cribbing.

These insights from research, expert opinions, and real-world examples illustrate the complex nature of cribbing and the importance of a multifaceted approach to managing this behavior.

By understanding the underlying causes and implementing appropriate management strategies, horse owners can help reduce the frequency and impact of cribbing on their horses’ well-being.
