The use of animal products in various industries has often been a subject of ethical debate. One such debate surrounds the production of glue, with a persistent myth claiming that horses are killed specifically for their hides to make glue. This misconception has fueled concern and misinformation, prompting a need to clarify the truth behind this claim.
Are Horses Killed to Make Glue?
The idea that horses are slaughtered solely for glue production is largely a myth. While it is true that animal collagen, derived from hides and bones, is used in the manufacturing of certain types of glue, the source of this collagen has evolved significantly over time.
Historical Context
In the past, when industrial processes relied heavily on animal-based products, horse hides were indeed used in glue production. However, this practice was primarily driven by the abundance of horses used for transportation and labor. As these industries declined, the demand for horsehide glue diminished.
Modern Glue Production
Today, the majority of glue used in various applications is derived from other sources, such as:
- Cow hides
- Pig skins
- Fish scales
- Synthetic materials
These alternatives are more readily available and often more cost-effective. The use of horse hides in glue production is now extremely rare, if not nonexistent, in most developed countries.
Are Horses Killed to Make Glue?
The idea that horses are slaughtered specifically to make glue is a persistent myth that has circulated for decades. While it’s true that animal-derived glue was historically made from collagen found in various animal parts, including horse hides, the practice is largely outdated and the notion that horses are routinely killed for this purpose is unfounded. This article delves into the history of animal glue, the modern-day glue industry, and the truth behind the myth surrounding horses and glue production.
The History of Animal Glue
Animal glue has a long and storied history, dating back centuries. It was a vital material used in various applications, from bookbinding and woodworking to construction and even as a food adhesive. The process involved boiling animal hides, bones, or other collagen-rich tissues to extract the gelatinous substance. This gelatin, when dried and rehydrated, formed a strong and flexible adhesive.

Sources of Collagen for Glue
Throughout history, a variety of animal sources have been used for glue production. Some common sources included:
- Horse hides
- Cow hides
- Pig skins
- Fish skins
- Bones
The specific animal source often depended on availability, cost, and the desired properties of the glue.
The Decline of Animal Glue
The 20th century witnessed a significant shift in the adhesive industry. The development of synthetic glues, such as polyvinyl acetate (PVA) and polyurethane, offered several advantages over animal-derived alternatives:
- Greater strength and durability
- Water resistance
- Versatility in applications
- Easier and more controlled production
These advancements led to a decline in the use of animal glue, particularly in industrial settings.
Modern Glue Production
Today, the vast majority of glue used in commercial and consumer products is synthetic. Animal-derived glue, while still produced in some niche markets, is no longer a primary source of adhesive.
Uses of Animal Glue Today
Although less common, animal glue still finds applications in specific industries and crafts:
- Bookbinding: Traditional bookbinding often utilizes animal glue for its archival qualities and ability to create a strong, flexible bond.
- Woodworking: Some woodworkers prefer animal glue for its natural appearance and its ability to create a strong, water-resistant bond in certain applications.
- Art and crafts: Animal glue is sometimes used in art restoration and other crafts where a natural adhesive is desired.
The Myth Debunked: Horses and Glue
The persistent myth that horses are killed specifically for glue production is simply not true. The decline of animal glue in the 20th century has rendered this practice largely obsolete.
Ethical Concerns and Animal Welfare
The notion that horses are slaughtered for glue raises ethical concerns about animal welfare. It’s important to note that the vast majority of horses are not killed for glue. Horses are primarily used for various purposes, including:
- Riding and equestrian sports
- Draft work
- Therapy and companionship
- Racing
The horse industry is governed by regulations and ethical guidelines that prioritize the well-being of horses.
Conclusion
The myth that horses are killed to make glue is a misconception rooted in outdated practices. While animal-derived glue was historically used, the modern adhesive industry relies primarily on synthetic alternatives. The ethical concerns surrounding the slaughter of horses for glue production are unfounded, as the practice is no longer prevalent.
It’s important to rely on accurate information and to dispel myths that perpetuate harmful stereotypes about animals and industries.
FAQs: Horses and Glue
Are horses killed specifically to make glue?
No, horses are not killed specifically to make glue. The use of horsehide for glue production is very rare today.
What is glue traditionally made from?
Traditional glue was often made from animal collagen, which can be derived from various sources, including horsehide, cowhide, and pigskin.
Are there alternatives to animal-based glue?
Yes, there are many modern alternatives to animal-based glue, such as synthetic glues made from petroleum products or plant-based glues derived from starches or proteins.
Why is horsehide glue not common anymore?
The use of horsehide glue has declined due to the availability of cheaper and more efficient synthetic alternatives, as well as ethical concerns surrounding the use of animal products.
Is it true that glue is still made from horses today?
While it is possible that some small-scale producers may still use horsehide for glue, it is not a common practice in the modern glue industry.
