What is the main function of the wall of a horse's hoof?

The main function of the wall of a horse's hoof is to provide support and protection for the internal structures. The hoof wall is a hard, keratinized structure that encases the softer components of the hoof, such as the sensitive laminae and coffin bone. This protective barrier ensures that the delicate internal structures are safeguarded from external injuries and environmental hazards.

Moreover, the wall also plays a crucial role in supporting the weight of the horse and maintaining its overall balance and posture as it moves. The strength and integrity of the hoof wall are essential for the horse's overall health and performance. Proper care and maintenance of the hoof wall, including regular trimming and attention to any signs of damage or disease, are vital to prevent issues that could arise from compromised hoof integrity.

While the hoof does assist in digital blood circulation, participate in shock absorption, and allow for some flexibility to facilitate movement, these aspects are secondary to the primary role of providing robust support and protection. Understanding the primary purpose of the hoof wall helps in appreciating its significance in equine health and management.
