What’s In Your Tack Trunk?

Equine First Aid Kit
All horse owners should have an equine first aid kit & know how to use all of the supplies. At least twice yearly, examine & replenish outdated supplies. Store your first aid kit in your home or temperature controlled space. Leaving it in a trailer or uninsulated tack room will quickly degrade the supplies. Talk to your veterinarian about customizing your first-aid kit for your horse’s particular needs.

Feeding a Draft Horse

Due to Draft horses being prone to certain diseases such as, metabolic ailments like PSSM (Polysaccharide storage myopathy), laminitis, Cushings, founder, tying-up, and shivers diet is imperative. Based on these ailments, starch and sugar calories should be replaced by fiber and fat calories.

It is recommended that these guys have high quality forage and some concentrates while working due to their slower metabolism (similar to ponies). Meaning that the less energy they use, the more weight they gain. High carbohydrate feed should be avoided, as a forage with a rational balancer and/or a low NSC feed.

Breakdown of How To Feed A Draft Horse

Calorie Breakdown:

  • 15% daily calories from sugar
  • 20-25% daily calories from, fat
  • No less than 1% of horse’s body weight in forage

Calculating Fat Content:

Pounds of feed per day x % of fat

For example,

3 lbs of feed= 3 x 0.25= 0.75 lb fat

Feed Brands:

Feeds should have no more than 33% sugar and starch (low carb).

Low in starch and sugars: soy, beat pulp, wheat bran, wheat middlings

Feeds with 20%+ of fat should be supplemented with rice bran (20% fat). Feed with anything less than 20% should be supplemented with 100% additional fat source.

  • Nutrena Compete
  • Purina Strategy
  • Blue Seal Hunter, Demand, Vintage Gold
  • Southern States Legend

Supplements:

  • Oil: soy oil, canola, corn oil, rice bran
  • Vitamin E & Selenium supplement (be careful when adding in selenium as high levels can be toxic)

The Plan

  1. Either Purina Strategy or Southern States Legend: No more than 5-6 lbs of feed per 1000 lbs
  2. Rice Bran Oil: begin with 1/4 cup and increase by 1/4 cup every few days until 2 cups are reached. Continue with 3-4 cups per day.
  3. Vitamin E with Selenium: 1-2 oz per day
  4. Forage: Alfalfa pellets mixed or substituted with Purina or Southern States feed

Mix 12 parts alfalfa (or Purina or Southern States Feed or mix of the two) with 1 part water. Soak for 10 minutes. Add in oil. Let it sit for 2+ hours. Right before feeding add in the supplement (Vet E/Selenium).

Why Not?

While agreeing to save the ponies from slaughter, I saw a beautiful, senior mare. She is a 17 hand, 17-year old, Belgian mare who was an Amish workhorse until put into the auction. She is visibility underweight and her coat is dull and patchy but her eyes bright and soulful. I watched to see if she got rescued as her slaughter date was for 5/7/2020. Well, last night, I took the plunge and purchased the sweet girl.

Ever since losing Chance I have not had a desire to get another horse. Over a year ago a neighbor gave me a thoroughbred mare but shortly after she arrived I realized I was not ready and I had just learned I was pregnant. Fortunately, I was able to find her a wonderful forever home. However, upon coming across this Belgian I knew she was my next heart horse. The thing is I only have one paddocked fenced in that holds three miniature donkeys. So I am quickly getting things in order- scheduled to have another paddock fenced in, a large run-in dropped off, and everyones vaccinations up-to-date. One of my neighbors has a barn and paddocks and no other horses on the property and generously offered to allow my new mare and friend’s two ponies quarantine there for 30 days. By the time quarantine is over, the fence and run-in will be up and ready for the new members of the family!

There is also a ton of research that I need to do about owning a draft horse. They are a special breed and more susceptible to metabolic disorders and a ton of hoof issues. Once again I will be using this platform as a way to organize my ongoing research. Wish me luck!

EQUINE BOTULISM: An unknown threat

Equine Botulism

Written by Dr. Tom Lenz on behalf of AQHA 

Few horse owners are aware of this disease which is a progressive, paralyzing disease that is 80-100% fatal in affected horses.  Botulism is sometimes referred to as “forage poisoning” in adult horses or “shaker foal syndrome” in foals. The disease is caused by a potent toxin that is produced by the bacterium Clostridium botulinum. This bacterium lives in the soil as well as the intestinal tract of many normal birds and mammals, including the horse. It produces dormant spores that can be found in 18.5% of soil samples tested in the United States. The disease is most prevalent in Kentucky, Ohio, Maryland, Pennsylvania, California, and Tennessee although it can occur in any state in the U.S. Clostridium botulinum produces several different toxins. Type A toxins are often implicated in human infant botulism and are most often found west of the Rocky Mountains. Types B, C, and D toxins are usually involved in cases of equine botulism, with Type B responsible for 85% of horse cases in the U.S.

Horses of any age are susceptible to botulism which may be initiated by one of three ways. In the case of “forage poisoning” the horse ingests toxins that are contaminating feedstuffs such as grain or hay. Feed contamination is most often due to putrefied carcasses of birds or rodents. A Type C botulism outbreak that killed a number of horses in California several years ago was traced back to hay that contained the infected carcass of a rabbit. The bacteria can also enter a horse’s body via contamination of a wound, especially a deep puncture wound. A good example is “Shaker foal syndrome” which is most frequently caused by the bacteria entering the newborn foal’s body through the foal’s moist navel. Something that can be minimized by dipping the foal’s navel in mild iodine solution soon after birth. The third method in which the disease can be initiated is by ingestion of the spores in the soil. The ingested spores activate in the horse’s intestinal tract where they produce potent toxins that are then absorbed. Regardless of the route, once the bacteria have entered the horse’s body they produce toxins that block transmission of nerve impulses to the horse’s muscles. This results in a progressive paralysis of all the major muscle groups and is concluded with paralysis of the diaphragm, which results in death. Once symptoms develop, death may ensue in several hours or take up to a week.

The disease is difficult to diagnose because it resembles several other medical conditions and diseases such as choke, colic, rabies, EPM, and sleeping sickness. Blood samples very rarely contain toxin and necropsy following the death of the horse usually does not provide a conclusive diagnosis. Because the bacteria often occur naturally in the horse’s intestinal tract, isolation of the organism from the sick horse’s intestine is not diagnostic.

Clinical signs of the disease in adult horses suffering from “forage poisoning” initially include loss of facial expression, a sleepy appearance, saliva drooling from the corner of the mouth, loss of tongue control and loss of tail tone. The horse’s appetite is good, but it has a great deal of difficulty in chewing food and appears to be “playing” in their feed and water buckets. As muscular weakness becomes more profound, the horse will experience muscle trembling, generalized sweating and labored breathing. A weakened, shuffling gait may develop and the horse may take stiff, short steps as if walking on eggs. Eventually, the horse goes down and death results due to paralysis of the respiratory muscles. “Shaker foal syndrome” is usually seen in foals one to two months of age but can develop as early as two weeks or as late as 8 months of age. Early signs in foals are similar to those seen in adults in that the foal shows generalized weakness, poor tail tone, and loss of tongue control. The foal will often dribble milk from the mouth and nostrils because of an inability to swallow. Because of muscle weakness, the foal will lie down frequently. When it does rise, it soon develops muscle tremors and collapses. Affected foals may die within 12 hours of exhibiting symptoms or may linger for as long as a week.

Botulism is usually fatal if left untreated. Prior to the advent of antitoxin, the death rate among affected foals was greater than 90%. With the use of antitoxins in conjunction with antibiotics and supportive therapy, the mortality rate can be reduced to less than 25%. Animals unable to swallow should be fed through a nasogastric tube and placed on IV fluids. Once the toxin produced by the bacteria is attached to the nerve ending it cannot be neutralized by the antitoxin. Therefore, early treatment is critical. Even with aggressive therapy, recovery is slow and may require up to two weeks before the affected horse recovers.

Because of the high death rate and the difficulty in diagnosing this disease, prevention through vaccination is critical. A Type-B Toxoid vaccine is available and is quite effective in preventing the disease. In areas where the disease is prevalent, pregnant mares should be initially vaccinated at the 8th, 9th and 10th month of gestation and thereafter at the 10th month of each pregnancy. Yearly vaccination of adults in areas where the disease frequently occurs is also recommended. If unable to vaccinate the mare prior to foaling, limited information suggests that foals vaccinated with the toxoid at 2 weeks, 4 weeks and at 8 weeks of age developed adequate protection, even in the presence of passive maternal antibodies. Currently, no licensed vaccines are available for preventing botulism due to Cl. botulinum types A or C or other subtypes of toxins. Cross-protection between subtypes does not occur.

As in all horse health issues, your local veterinarian is your best source of information.
