Alternative horseshoeing methods
New non-invasive horseshoeing methods are available for farriers to take advantage of. They encapsulate the damaged hoof, protecting and supporting the sensitive internal structures. This prevents further deterioration, whilst also immediately reducing pain and improving the horse’s ability to move. The resulting comfort also reduces overall stress levels, leading to a faster recovery as the horse can quickly return to a regular routine. Aggressive therapies
Dorsal hoof wall resectionA dorsal hoof wall resection may help in certain conditions after consultation with an experienced veterinarian and farrier team. If decreased bloodflow distal to the coronary plexus is seen on a venogram, or when a laminar wedge forms between P3 and the hoof wall, preventing the proper reattachment (interdigitation) of the laminae, this procedure may be beneficial. When the coffin bone is pulled away from the hoof wall, the remaining laminae will tear. This may lead to abscesses within the hoof capsule that can be severe and very painful, as well as a mass of disorganized tissue called a laminar (or lamellar) wedge. Coronary groovingCoronary grooving involves removing a groove of hoof wall just distal to the coronary band. It is thought to encourage dorsal hoof wall growth and improve alignment of the wall. Deep digital flexor tenotomy
Because the rotation of P3 is exacerbated by continued pull on the deep digital flexor tendon, one approach to therapy has been to cut this tendon, either in the cannon region (mid-metacarpus) or in the pastern region.
Many of the substances that protect us from excess copper perform important functions in our neurological and endocrine systems, leading to diagnostic difficulties. When they are used to bind copper in the plasma, to prevent it from being absorbed in the tissues, their own function may go unfulfilled. Such symptoms often include mood swings, irritability, depression, fatigue, excitation, difficulty focusing, and feeling out of control. To further complicate diagnosis, some symptoms of excess copper are similar to those of a copper deficit. The U.S. Environmental Protection Agencys Maximum Contaminant Level (MCL) in drinking water is 1.3 milligrams per liter. The MCL for copper is based on the expectation that a lifetime of consuming copper in water at this level is without adverse effect (gastrointestinal). The US EPA lists copper as a micronutrient and a toxin. Toxicity in mammals includes a wide range of animals and effects such as liver cirrhosis, necrosis in kidneys and the brain, gastrointestinal distress, lesions, low blood pressure, and fetal mortality. The Occupational Safety and Health Administration (OSHA) has set a limit of 0.1 mg/m3 for copper fumes (vapor generated from heating copper) and 1 mg/m3 for copper dusts (fine metallic copper particles) and mists (aerosol of soluble copper) in workroom air during an eight-hour work shift, 40-hour work week. Toxicity to other species of plants and animals is noted to varying levels. EPA cancer data
The EPA lists no evidence for human cancer incidence connected with copper, and lists animal evidence linking copper to cancer as "inadequate".
