Conformation of the equine skull: a morphometric study.

This study aims to establish a new method for quantifying horse skull morphology. It was applied to 30 living and deceased horses of multiple breeds to highlight disparities and similarities in equine skull structure.

Research Methodology

The researchers conducted an intricate morphometric (measurement-related) study focused on horse skulls. Nine measurements and six indices or indices were computed for each horse in the study. The parameters studied were:

• Skull length
• Cranial length
• Nasal length
• Ratio of cranial:nasal length
• Cranial width
• Zygomatic width
• Mandibular depth
• Nasal profile area
• Cranial profile area

The indices used were:

• Skull index
• Cranial index
• Nasal index
• Mandibular index
• Nasal profile index
• Cranial profile index

To separate the neurocranium and splanchnocranium, a line was drawn level to an anatomical landmark found caudal to the lacrimal process of each orbit. The study group consisted of 30 horses from different breeds, and their measurements were taken while their head soft tissues were still intact.

Findings

The results revealed numerous positive correlations among many head measurements. Another important finding was the significant differences in skull morphology among three breeds – Arabians, thoroughbreds, and standardbreds. These differences suggest that the method proposed in this study is meticulous and reliable in differentiating skull structures among different horse breeds.

Significance

The research is significant as it provides a reliable method for quantifying equine skull morphology which can be used both for live and deceased horses. It helps to understand the difference in skull structure among various breeds. The results of the study may prove beneficial for researchers in the study of equine health and anatomy, breeders, veterinarians, and others involved in the horse industry. The method proposed could potentially lead to improvements in horse care, breeding, treatment and understanding of equine diseases that impact the skull.
