Laminitis research: Feeding a high starch diet can influence PPID (Equine Cushings Disease) test results

Summary: New research, conducted in collaboration with the British horse feed company SPILLERS®, has shown that the equine diet, and more specifically, a starch rich food, can influence adrenocorticotropin hormone ,or ‘ACTH’, test results. This could potentially lead to an incorrect disease diagnosis in some horses when ACTH is used to test for Pituitary Pars Intermedia Dysfunction (PPID).

Key point: The threshold values for diagnosis of the disease currently vary dependent on the season, but these new findings suggest that diet should also be considered. 

Hoof Blog note: Laminitis in older horses is commonly blamed on PPID, but a definitive diagnosis by hormonal test results is required to determine if an underlying endocrine condition is the cause of laminitis. Some horses with PPID may lose weight, which might lead owners to increase feed or change to a higher-starch diet to counter weight loss. Horse owners and veterinarians should communicate about a horse's feed intake before testing; future research may reveal more specific guidelines about how feed type influences test results.

Hidden Anatomy: Researchers Make a Case that Modern Horses Have Five Toes--Even If We Can't See Them

One of the keys to the Solounias research is the leafy construction of the Eponychium hoof covering in the fetal horse. The researchers dissected fetal hooves and paid close attention to the construction of the Eponychium. From left: Medial view of fetal horse hoof;  Dorsal view of the fetal hoof, showing a smooth singular surface, representing the dominant digit III; Ventral view of a fetal horse specimen, showing four distinct infoldings that depict evidence of the Solounias paper's proposed digits I, II, IV and V.  (Detail from one of the many figures in the article.)

Scientists have long wondered how the horse evolved from an ancestor with five toes to the animal we know today. While it is largely believed that horses simply evolved with fewer digits, researchers at New York Institute of Technology College of Osteopathic Medicine (NYITCOM) pose a new theory suggesting that the remnants of all five toes are still present in the distal limb of the horse.

USDA Invites Tennessee Walking Horse Owners, Trainers to Horseshoeing Clinic Aimed to Improve Horse Protection Act Compliance

This public announcement is provided by the US Department of Agriculture.

On February 3, 2018, USDA Animal Care and the S.H.O.W. horse industry organization will hold a shoeing clinic for trainers, exhibitors and owners who participate in events regulated under the Horse Protection Act to help these individuals better understand and follow the federal regulations.

The Copper Horseshoe Revival: Why modern farriery's quest for healthier hooves passes through a forgotten footnote from industrial history

      This story was sponsored by Stromsholm Farriers Supplies, UK.

Copper: Why is the warm, soft red metal suddenly showing up on horses’ hooves? First it was copper sulphate compounds added to hoof packing and even hoof wall adhesive. For years, pads have been fixed to shoes with copper rivets. During the past few years, farriers have experimented with new copper-shielded nails to improve hoof wall health. Copper-alloy horseshoes have been patented in Germany and South America.

Copper is suddenly part of the conversation.

It sounds like something new, but long ago copper was spelled out in a critical footnote in farrier materials history as well as in industrial safety. Copper is still the same metal but the newest uses of it are rewriting the script, putting the metal to use for reasons never dreamed of in the past. Here, we'll look at the past and present of copper in the hoofcare world, and leave it to all of you to decide whether it has a future or not.

Laminitis researcher investigates horse owners’ knowledge of disease and how it affects horse care decisions

A new laminitis research study, supported by the equine feed manufacturer SPILLERS®, in collaboration with the Royal Veterinary College (RVC) in England, aims to shed light on British horse owners’ understanding of laminitis and whether or how that knowledge may influence horse management practices in Great Britain.

Farrier "Teams" Will Be On Site for FEI World Equestrian Games™ Tryon 2018

Edited from press release

The American and International Associations of Professional Farriers (AAPF/IAPF) have announced an agreement to provide emergency farrier services for the Fédération Équestre Internationale (FEI) World Equestrian Games™ Tryon 2018 (WEG) at Tryon International Equestrian Center in Mill Spring, North Carolina in September.

Researchers: Tennessee Walking Horse Shoeing and Chains Caused No Pain, Stress or Inflammation in University of Tennessee Study

When efforts to increase Horse Protection Act restrictions on how Tennessee Walking horses are shod failed at the end of 2016, the shows went on, under the pre-existing rules, throughout 2017. Walking horse inspections by USDA and industry groups continued, but there were few new headlines. But the year ended with announcement of new research results on hoof pad stacks and pastern chains, conducted at the University of Tennessee Knoxville's College of Veterinary Medicine. The paper will be in the January 2018 edition of the American Journal of Veterinary Research, published by the American Veterinary Medical Association.  The horse in this photo wears pad stacks and chains on its front feet, as currently allowed under the Horse Protection Act, and is not one of the horses in the study.

Eight veterinarians and animal science researchers at the University of Tennessee Knoxville have collaborated on a study testing the effects of hoof pad stacks and chains on a group of Tennessee Walking horses. In what would literally be the closing hours of the 2017 calendar year, the American Journal of Veterinary Research (AJVR) posted the new research paper online.
