Lake View Veterinary Services offers equine surgery with an emphasis on lameness and traumatic wounds. We now have digital x-ray and use fluoroscope guidance for joint injections. We recently added stem cell therapy to our arsenal of tools for battling equine lameness. We like to work directly with your farrier on many cases or we do have a very good farrier available to do corrective shoeing at the clinic when needed.
We have a hydraulic surgery table with a padded recovery stall and 4 indoor temperature controlled stalls reserved for surgery or hospitalized cases.
We offer artificial insemination and are a semen receiving station for frozen and fresh semen. We have a separate breeding barn that has 10 indoor stalls as well as having multiple outdoor runs for mares.
We no longer stand or collect stallions.
Equine Herpes virus - 1
Equine herpes virus - 1 (EHV-1) is one of five herpes viruses commonly found in horses. There are 3 types of herpes virus - respiratory, reproductive and neurologic.
As in other herpes viruses EHV-1 can be found in herds that have not had new arrivals. While vaccination, quarantine of new stock, segregation of young stock, show stock and breeding stock are important to proper management it is important to know that vaccination only provides short-term immunity (4-5 months) and even during that time is not completely protective. Horses that are well vaccinated can develop disease.
Respiratory form of EHV-1 is usually mild and resolves itself without very much need for treatment. Symptoms include nasal discharge, mild lethargy and fever.
Reproductive disease is generally the most economically important form of EHV-1. This infection causes abortion in the last trimester of pregnancy. Foals that are affected are occasionally born alive but are often very weak and die within days of birth often with a secondary disease condition. The virus infects the mare through the respiratory tract and then travels through the bloodstream and infects the foal. Often time the virus that infects the mare is so mild and is not recognized and abortions occurs spontaneously.
Following any abortion the mare should be isolated, the foal and placenta should be promptly submitted to a diagnostic laboratory to determine cause. Fetal tissues and fluids should be considered infectious, all areas in contact cleaned with a detergent and disinfected, contaminated shavings or straw should be discarded and not spread where any horses may come in contact.
EHV-1 abortions can occur singly or may spread rapidly within a susceptible population. With proper vaccination protocols as well as better management the number of cases of EHV-1 abortions has decreased significantly over the past 3 decades. An effort is being made to develop a more effective vaccine that provides long-term immunity.
The neurologic form of EHV-1(equine herpes virus myeloencephalopathy) is less understood. Sudden ataxia (staggering) or paralysis often with urinary incontinence, tail weakness/elevation , etc. can occur. Outbreaks are often in more dense populations such as racetracks, boarding facilities, large shows, etc. Often times these horses are well vaccinated which seems to not be protective or being a risk factor.
While the diagnosis of the disease if well understood , the production and development of the disease is not well known. Prevention of the outbreaks of EHV-1 relies on the close monitoring and prompt isolation of affected horses and quarantine of the premises.
