A Novel Non-Invasive Selection Criterion for the Preservation of Primitive Dutch Konik Horses.

The study investigates the uniqueness of the Dutch Konik horse‘s distal limb anatomy to be used as a non-invasive selection criterion for conservation and breeding purposes.

Study Objectives

• The study aims to identify a non-invasive selection criterion that is potentially unique to the Dutch Konik horse. This is important for genetic conservation and for maintaining the natural landscapes where these horses graze.
• This research also focusses on the investigation of the anatomic parameters of the distal equine limb, specifically the lengths of individual splint bones.

Traditional Breeding Selection

• The conventional method for breeding selection is based on phenotypic characteristics in compliance with the breed description. However, the researchers found that selecting animals for removal from the breeding program can be challenging due to the high uniformity within the breed for features such as wither height, color, and the presence of primitive markings.

Methodology and Results

• The researchers performed post-mortem dissections on the distal limbs of Dutch Konik horses (47 in total) and modern domesticated horses (120 in total).
• They discovered significant differences associated with the length and symmetry of the 2nd and 4th Metacarpals and Metatarsals between the two groups.
• They identified distinct distal limb characteristics in the Dutch Koniks that could be used as a non-invasive selection tool for maintaining and preserving the breed.

Conclusion

• The study suggests that these unique distal limb characteristics of Dutch Konik horses can serve as a useful additional criterion in the non-invasive selection process for the preservation of the breed’s genetic integrity and the natural landscapes they preserve through grazing.
