Genetic basis of hoof wall separation disease in Connemara ponies discovered

In April, a research paper by Carrie Finno, Carlynn Young, Amy Stevens and their team was published on the website PLOS Genetics. Their exciting research revealed that this devastating disease, affecting Connemara Ponies that causes the dorsal hoof wall to pull away from the laminae at the white line, is an autosomal recessive disease. 

A frameshift in the SERPINB11 gene causes a premature stop codon leading to insufficient protein production. Likely this is associated with keratinocyte proportions that in the hoof wall, which are most prevalent in the coronary band where hoof wall growth begins. 

This discovery could eventually lead to a genetic test to help breeders make decisions about ponies that carry the disease but don't show physical symptoms instead of just managing ponies that receive two copies of the recessive gene and suffer with the disease. 

I've summarized their genetic research in the infographic on the left.

Legends of Ranching horse sale coverage: Video tour

5/8/2015

This year’s 10th anniversary Legends of Ranching Performance Horse saleincluded a futurity and maturity demonstration on Friday night. Four consignors were invited to show horses in the demonstration, which included dry work and cattle work. Dr. Denniston, the horse-judging instructor and judging team coach, narrated each horse’s run, which highlighted their exceptional qualities.

Horses that are sold during this year’s sale will be eligible to compete in next year’s inaugural futurity and maturity event during the 11thannual legends of ranching sale.

During the preview on Saturday morning, aged horses did dry work and worked cattle. The consigned colts were ridden in the arena by their student trainers, giving potential buyers a chance to see them in action before the one o’clock sale start time.

The fast-paced auction took just over two hours to sell approximately 50 horses.

The top selling aged horse, Docs Tequila Snort, consigned by Singleton Ranches went for $16,000. Dyllan Freeburg, who was also the winner of last week’s Wagonhound Land and Livestock student competition, trained the top selling colt SCR Peptos Parton who sold for $14,000, and was consigned by Spur Cross Ranch. (See all the sale results on the Equine Sciences website).
