The Disease |
Hoof Wall Separation Disease (HWSD) is an inherited disease of the hoof. In affected animals, the hoof wall can easily break and crack and a normal appearing coronary band. The breaks and cracks begin to occur in young ponies. In severe cases the pony load its weight entirely on the sole of the foot which can lead to severe lameness. |

Clear
Genotype: N / N [ Homozygous normal ]
The horse is noncarrier of the mutant gene.
It is very unlikely that the horse will develop Connemara Pony Hoof Wall Separation Disease. The horse will never pass the mutation to its offspring, and therefore it can be bred to any other horse.
Carrier
Genotype: N / HWSD [ Heterozygous ]
The horse carries one copy of the mutant gene and one
copy of the normal gene.
It is very unlikely that the horse will develop Connemara Pony Hoof Wall Separation Disease but since it carries the mutant gene, it can pass it on to its offspring with the probability of 50%. Carriers should only be bred to clear horses. Avoid breeding carrier to carrier because 25% of their offspring is expected to be affected (see table above)
Affected
Genotype: HWSD / HWSD [ Homozygous mutant ]
The horse carries two copies of the mutant gene and
therefore it will pass the mutant gene to its entire offspring.
The horse is likely to develop Connemara Pony Hoof Wall Separation Disease and will pass the mutant gene to its entire offspring

Sample Requirements |
Hair Sample from mane with roots (approx 30 hairs) or 1 ml whole blood in EDTA tube.
How to obtain a viable hair sample
Pull around 30 hairs from the mane of the horse with the roots (in faols hair from the tail maybe taken). Wrap the hairs around your finger or a comb, as close as possible to the skin to ensure you obtain the hair roots. Keep dry, put in a bag, label the bag with the horse name, test (s) required. Place in an envelope and send back to us together with the order form. Broken or cut off hair will not be accepted.
