Educational Resources for Horse Owners

While thinking about a topic for this blog, I thought of educational resources that are out there for horse owners. Below are some Extension related websites that you may be interested in. You can call or email your local Extension Agent with horse related questions.


North Carolina Cooperative Extension and Extension Horse Husbandry have a webcast series (Elluminate). The webcasts start at 7pm and are free. Some Extension Offices host the webcasts or you can watch from home. The next webcast is February 21st on Legal Issues to Consider as a Horse Owner presented by Dr. Mike Yoder, PhD, NC State University. There will also be a webcast on March 13th on Ask the Professional Trainer, Questions & Answers by Robin Lynn, BS, NC State University. For more information, contact your Local Extension Agent or go to NCSU Webcasts.


eXtension is a partnership of universities in the United States to provide research-based information and learning opportunities in many different areas. There is a section on Horses which has articles, upcoming and archived webcasts, and a calendar of events. Go to eXtension Horse Resources to learn more.

Another resource is the My Horse University (MHU). My Horse University started in 2005 at Michigan State University. MHU brings research and knowledge from world-renowned experts to online courses and products. MHU’s courses provide a comprehensive and convenient learning experience for horse enthusiasts throughout the world. MHU has free webcasts and online courses at a cost. Go to My Horse University. I came across this webcast from My Horse University - Find your Dream Job in the US Horse Industry. This was a very interesting webcast with potential jobs.

Equine Herpesvirus ( EHV-1) Update

From Dr. Tom Ray:

All but two of the quarantined premises and all of the horses located on those farms have been released from quarantine. There have been no other horses that have shown clinical signs, run fevers or become ill since the initial mare was confirmed positive to EHV-1. Six horses were traced to Virginia and seven to Tennessee and the state and federal animal health officials in those states have located all of these animals; quarantines protocols were put in place, animals observed for clinical signs and fevers, and no further cases have been reported in those states as well. The last two quarantined facilities in NC are expected to have their restrictions removed in the next week to 10 days, assuming no evidence clinical signs or fevers show up. Because the outbreak was fortunately contained and all exposed located and quarantined so quickly, we have not recommend cancelling any equine events in North Carolina. Also, no other states have placed any movement restrictions or increased testing requirements on horses from our state. As the State Veterinarian for Tennessee correctly remarked, “This outbreak has pretty much burned itself out!” (We’ll still just knock on wood!).

From Dr. Niki Whitley:



· The one confirmed EHV-1 positive horse in NC has recovered with all tests now negative but is still in quarantine (on-farm in VA).

· No other cases in NC or for the six horses traced to VA and seven traced to TN.

· The last two facilities under quarantine in NC should be released in 7-10 days (if nothing happens).

· NCDA&CS has NOT recommended equine events in NC be cancelled.

· No states have restricted movements or increased testing requirements for NC horses.

St. Andrews University Offers Unique Equine Education




Nestled into the farming landscape of Scotland County, North Carolina is the 100-acre St. Andrews University Equestrian Program. Although I have lived 20 minutes from this facility for over eight years, I've never taken the opportunity to learn more about it, until yesterday. The purpose of the visit yesterday was to learn about the program and write it up for this blog. The program is very multifaceted, and it will be hard to describe all that they do, so I will include the website address at the bottom of the post. Like many other colleges and universities in North Carolina, St. Andrews has competitive teams that compete in the IHSA (Intercollegiate Horse Show Association), and they have hosted several events at their facilities in Scotland County. I met with Peggy McElveen, the Equestrian Director, and she showed me the different units (Western Stables, English Stables, Student Horse Boarding Stables, and Covered Arena). The facility is very nice and exists because of a lot of hard work, donations of time and money, and grants received.



I was most intrigued by the Therapeutic Horsemanship Program, one of the first in the nation and the University’s "Ride like a Knight" Program. This program serves individuals with Attention Deficit Disorder (ADD) or Attention Deficit Hyperactivity Disorder (ADHD), At-Risk Youth, Autism, Cerebral Palsy, Developmental Delay or Disability, Downs Syndrome, Hearing Impairment, Learning Disability, Mental Retardation, Multiple Sclerosis, Muscular Dystrophy, or Speech Impairment. The University also works with the Wounded Warrior Project. The Wounded Warrior Project's mission is to "foster the most successful, well-adjusted generation of wounded service members in our nation's history." The program at St. Andrews allows the opportunity for wounded veterans to get back in the saddle or, in some cases, it allows veterans who have never been on a horse the opportunity to ride. For more information about this program and the other equine programs at St. Andrews University, visit the school's website. That link, as well as the PATH (Professional Association of Therapeutic Horsemanship International) and Wounded Warriors link, is below.

The 1-2-3's of Foaling

With springtime on the horizon, some of you may have mares in foal and be making final preparations to introduce one or more youngsters to your herd. If you are a veteran to foaling, this information shouldn’t be anything new, however, if it has been a while or if your first encounter with a new arrival, the following information should be helpful to your success. There are two types of “1-2-3’s” that are important. First, we will talk about the three stages of labor. Then, I will discuss the 1-2-3 rule on newborn foal behavior and health of the mare and foal.

Let’s start with the stages of labor. Mares more often than not foal at night. The usual hours are in the 10pm-2am timeframe, but let’s face it, this could really happen anytime. There are many changes in the mare as she gets close to foaling that you may experience, even though these changes can vary greatly as well. First, mammary development usually takes place in the last 10-15 days of gestation, with the average gestation length being 340 days (range of 320-365), or about 11 months. Muscles in the croup and tail area will soften, and waxing will occur on the teats. Calcium concentration in the milk will rise, and many mare owners use a milk calcium test to check for this. Water hardness strips are a great tool and indicator to use for checking milk calcium levels. By mixing .25 mL of milk with 1.5 mL of distilled water and dipping strips in the solution, you can look for an orange/reddish color to indicate foaling in less than or equal to 48 hours usually.

When its time to foal, you will experience the three stages of labor. Stage one is where the mare appears somewhat uncomfortable. She may appear to be experiencing mild colic symptoms, be restless and uneasy, have a decreased appetite, may pace around and be sweating. Stage one might turn quickly into Stage 2, or it might take up to 24 hours. Stage 2 begins with the water breaking, and should last no more than thirty minutes. Most often stage 2 will take only up to ten minutes. The “water breaking” is the breaking of the chorioalantois membrane of the placenta. If this membrane appears and has not ruptured, it is important to quickly open it. At this point, the mare will most likely be lying down, but she can get up and down and this is still normal. The majority of mares will deliver the foal just fine without assistance, but if it’s taking a while or if the mare insists on standing, intervening will be necessary. If stage 2 takes more than 30 minutes, dystocia (difficult birth) is most likely occurring and a veterinarian should be called. If more than an hour goes by, the foal’s life is definitely in danger, and most often death will occur. There are several types of dystocia, such as having a leg back, the head back, or even the breech presentation. The mare will need assistance in any of these cases. After delivery, the mare may rest for up to one hour before standing, and the umbilical cord will remain attached. After the cord breaks naturally (we should not break the cord) it should be dipped in an iodine or chlorhexidine solution. A 2% Betadine solution is a good choice. Now we are ready for stage 3, which is expulsion of the placenta. This should take less than five hours, and most often occurs within one hour after foaling. If the placenta is not expelled within six hours, call the vet. Problems associated with a retained placenta could be laminitis, metritis (uterine infection), septicemia (bacterial infection of the bloodstream), or even death. During stage 3 the mare may seem slightly colicky for various reasons and is not uncommon. She should be monitored closely. At the end of the three stages, it is important to notify your veterinarian of the birth (if you haven’t already called). Your vet will want to come see the foal and take a blood sample to screen for “NI” or neonatal isothrolysis, to make sure the foal and mare’s blood types are compatible and the foal is off to a healthy life, not to mention check over the foal’s general appearance and behavior.

Now let’s talk about the “1-2-3 rule” of foaling, which is directly linked to the health and well being of the foal and the mare. Ideally, you will want the foal to stand within 1 hour, nurse within 2 hours, and have the mare expel her placenta within 3 hours. As always, this might not happen exactly on time, but within reason. If your mare is due to foal this spring, monitoring her and the foal with these “rules of thumb”, so to speak will hopefully be helpful to you. However, when in doubt, call your veterinarian!

Equine Herpesvirus ( EHV-1) has been confirmed in a North Carolina Horse

Update on EHV from Wednesday, 1/11/2012 Summary:
· There are 45 horses and 1 donkey under quarantine on 7 locations in 4 counties in NC; 37 of the animals are at a single premises, the other 9 on the remaining six quarantined location.
· Additionally, there are 7 horses traced out to Tennessee at two locations and 2 horses to Virginia at one location.
· Six of the seven quarantined locations in NC are expected to have their quarantine lifted by Tuesday, January 17, 2012 (assuming no fever spikes and/or observations of clinical signs).

As you can see, this situation is pretty much confined, all exposed animals have been located, quarantined, and being closely observed for any fever spikes and/or clinical signs. NCDA&CS, Vet Division field staff have been in close and regular communication with owners at these sites and will continue to do so until all the quarantines are lifted. Because the sites were identified, the exposed animals located and quarantined so quickly after suspicion of EHV-1, there has not been a recommendation to cancel equestrian events in the state. Also, no other states have notified our State Veterinarian’s Office of any movement restrictions on horses moving from North Carolina into their states.

If you have further questions or comments, please do not hesitate to contact me by any of the methods listed below.

Thank you.

Virus affecting horses found at N.C. stable


Virus is contagious between horses, but does not affect humans

RALEIGH – The neurologic form of equine herpesvirus, EHV-1, has been confirmed in a North Carolina horse. The horse, from a Rockingham County stable, was taken to the College of Veterinary Medicine at N.C. State University upon becoming ill, and directly quarantined to the equine isolation unit of the hospital.

“We have been fortunate that we’ve not seen this particular form of this common virus in North Carolina to date, even though it has been increasing in frequency throughout the country for almost a decade now,” said State Veterinarian David Marshall. “We are working with the College of Veterinary Medicine and with the stable to implement biosecurity measures and minimize the risk of further spread.”

EHV-1 is highly contagious among horses, but poses no threat to humans. It most often causes respiratory infections in young horses, but different strains can also pose neurologic problems, which the affected N.C. horse exhibited. The virus also can cause abortion in pregnant horses or neonatal death. Vaccines are available that protect horses from most forms of EHV-1, but not from the strains that cause neurologic problems.

Biosecurity measures to protect horses include quarantining facilities that are suspected to house EHV-1-exposed horses. Water and feed buckets should be disinfected and not shared. Stalls and trailers should also be cleaned and disinfected regularly to prevent the spread of disease. New additions or those returning from shows and exhibitions should be isolated for 3 weeks prior to comingling with other horses upon returning home. Horse owners should also talk with their veterinarian to determine a vaccine schedule.
More information about EPV-1 and how to prevent the virus can be found at http://www.ncagr.gov/vet/Disease%20Alerts.htm. Questions regarding College of Veterinary Medicine protocols may be referred to David Green at 919-513-6662.

There are no horse events scheduled this weekend at facilities owned by the N.C. Department of Agriculture and Consumer Services in Raleigh, Williamston and Fletcher.

Treating Cuts

Most animals have a way of getting themselves in trouble.  However, horses seem to have a very good knack for that.  Just when you think you have removed any and all obstacles that can cause harm or damage to your horse, they seem to find that one minor thing that you overlooked.  Because we know horses can get themselves into big trouble, it is important to be prepared for those times. 
A First-Aid Kit is a must for anyone with horses.  Having the correct supplies easily accessible is critical to making sure the horse survives and heals from the tragedy.  There are certainly many emergencies that horse owners may find themselves in; however, this article is going to address how to treat cuts and tears.  This is certainly not meant to be an all-inclusive article as each case is different.  This is to try and help you be prepared in those emergencies until your veterinarian can arrive. 
If your horse cuts himself, here is a basic list of bandaging materials that would be helpful.
BANDAGE MATERIAL: (There are many types of bandage material that work well)
• 4X4 gauze squares (to clean and cover wounds and to hold wound medications in place)
• 4” wide roll gauze and roll cotton (to cover the gauze, pad the leg, and support the leg)
• Flexible, self-adhering leg wrap, such as Vetrap (to be used only over adequate padding)
• 2” wide adhesive tape (to hold everything together)
• Duct tape (where a water proof covering is needed)
• Bandage scissors

Additionally, some medications might be necessary when dealing with a wound.  A list is below.
MEDICATIONS: (There are a number of medications that might be useful. Make sure that you
                are aware of expiration dates and discard expired medications.)
Mild soap for cleaning wounds
• Mild antiseptic for killing bacteria that will inevitably get into a wound
• Pain relieving drugs - Aspirin is available over the counter and your vet may be willing to
                prescribe drugs such as flunixin (Banamine), phenylbutazone (bute), or a tranquilizer
• Hypodermic needles and syringes will be needed if you use injectible products
Additional information concerning first-aid kits and treating emergencies can be found at the following links.
So, you’ve just found your horse has a laceration.  You go get your newly organized first-aid kit.  Now, what do you do?  Here are some basic guidelines on how to treat a cut or tear.  (The below article is adapted from Craig Wood at the University of Kentucky.)
Wounds require immediate attention and first aid treatment. The seriousness of a wound depends on the location, depth, type of cut or tear, amount of tissue damaged, and type of tissue affected. Serious wounds should be treated by a veterinarian. All cuts and tears should be cleaned thoroughly and all foreign debris removed. Apply nitrofurazone or an antiseptic ointment to the wound.

Treatment
In treating cuts and tears, there are six steps to follow.
1. The first step on any cut or tear is to stop the bleeding. Blood from a cut artery spurts and is bright red. Venous blood is dull red and flows rather than spurts. Direct pressure is required for almost all cuts and tears. Pack gauze into large or deep wounds and apply pressure until the bleeding stops. Very seldom will a tourniquet be needed. Apply direct pressure on a wound with a gauze pad using your hand or a tight bandage. If a tight bandage is used to stop the bleeding, it should be removed once the bleeding has stopped.
A horse can lose up to 10 percent of its blood before the loss becomes critical. A 1,000-pound (454 kg) horse has about 50 quarts of blood. A horse can tolerate a slow blood loss, whereas rapid loss of blood can be critical.

2. The second step is to clean the wound with warm water and to remove all dirt and debris. The best way is to use a hose with running water to clean the wound. If water is not available, use a gauze pad to clean the wound. Press the gauze pad into the wound. Don't rub or swab the wound because that will cause further tissue damage. Avoid using cotton because pieces of it will remain in the wound. The hair should be clipped or shaved from the edge of the wound.

3. The third step is to immobilize the wound to prevent further damage. Hold the horse or place the horse in a box stall. Try to prevent the horse from chewing the wound or bandage. A neck cradle prevents chewing of most wounds. Cayenne pepper or hot pepper sauce applied to the bandage can discourage a horse from chewing. If the wound requires suturing, the veterinarian should do so within 12 to 24 hours for best results.

4. The fourth step is to prevent infection. Antibiotics should be administered under the direction of a veterinarian. Wounds can be treated with a nonirritating wound dressing. Minor skin wounds can be treated with nitrofurazone.

5. The fifth step is to protect the wound from dirt and other debris by applying a bandage. A bandage may decrease movement and promote faster healing of the wound. However, care must be taken when applying a bandage because, if it is applied incorrectly, it can cause more damage than good.

6. The final step is to prevent tetanus. If the horse has not been vaccinated against tetanus within the last eight to 12 months--or if you are unsure when its last tetanus vaccine was given--administer the tetanus antitoxin. Tetanus toxoid should be given every 8 to 12 months.

Here are a couple of additional articles that may provide some more beneficial information.  The key is to be prepared and not panic.  And call your veterinarian.
