Horsemanship and Showmanship Clinic by Gary Herson and Kris
Klingaman. RSVP to rbitterman@hotmail.com
Iowa Horse Judges Certification Clinic
November 1st
Anna Pesta will be the clinician at the 2014 clinic.
Anna is a graduate student at UNL pursuing a Ph.D.
in Ruminant Nutrition with an emphasis on feedlot
cattle. Originally from North Carolina, Anna was very
active in the youth 4H horse
program and was a member of AQHYA World Show
and Congress Champion youth teams. She then
attended Kansas State University where she was a

Senior College Team. She also competed on the
Meats and Livestock Judging Teams while at K-State. Anna has since
judged 4H and open shows extensively throughout Kansas and

programs and is always happy to help out 4H programs. Anna resides in
Lincoln with her corgi and actively competes her off-the-track
Thoroughbred in Three Day Eventing and stays busy with project horses

The clinic is for individuals with a desire to
learn the basics of horse show judging or
improve their judging skills. Individuals
successfully completing the clinic and a written
examination will become certified Iowa horse

opportunity to judge 8-10 conformation and
performance classes. More Information
The Iowa 4-H Horse Judging Contest is held at the same time.

Equine Allergies: Diagnosis and Treatment
By McKenzie Schaffer and Dr. Peggy Miller
Most horses will exhibit some sort of health issue throughout their life, either minor
or major, but when horse owners think of horse health problems, equine allergies
are probably not on their list. Allergic reactions in horses are not uncommon and
many reactions resolve on their own. However, when a horse frequently or
chronically reacts to a stimulus, things become complicated very quickly. Symptoms
from their reactions can affect their comfort and ability to perform. The horse must
first be tested to determine what exactly it is allergic to. Then the veterinarian and
the owner must work together to find a unique, long-term, and effective treatment
for the horse. Continue Reading

Anthelmintic Resistant Parasites in Horses
by Brandi DeVore and Dr. Peggy Miller
Anthelmintic drugs are used to control parasitic worms in horse's intestines. The three
main types of anthelmintic drugs used in horses are benzimidazoles,
tetrahydropyrimidine pyrantel, and macrocyclic lactones (Peregrine et al., 2014). These
drugs control Parascaris equorum and cyathostomins which are some of the most
common parasites of horses (Peregrine et al., 2014). These drugs are usually given as
part of a worming program that could include daily, monthly, or bimonthly doses. With
a routine dosing of horses with anthelmintic drugs resistant parasites are being
selected for and have been found in at least 15 countries (Peregrine et al., 2014). Looking at the parasites
anthelmintic drugs treat, the three main types of drugs in this category, and the problems that resistance to
these drugs cause, the full effects of this growing problem can be seen. Continue Reading

AAEP Ask the Vet
I have a companion donkey. My horse contracted lungworm. Do you believe
horses and donkeys can be kept together?
Lung worms are a pretty unusual problem in horses in the United States.
When they do get infected, it is usually from donkeys. Donkeys infected with
lung worms usually show no clinical signs of disease. In horses, the parasites
only very rarely can complete their life cycle, so the transmission almost never

goes the other way.
It's harder to make a definitive diagnosis of lungworms in horses than it is in
donkeys. With donkeys, diagnosis can be made with a fecal test, but that
generally doesn't work in horses.
Donkeys and horses can certainly be kept together, but you'll definitely want
to test them, and deworm as appropriate. Ivermectin dewormers are usually effective against lungworms.
Work with your veterinarian to come up with a problem that's ideal for your setting. David Ramey,

Horse Owner Not Liable for Farrier's Death Because He Assumed the Risk of
a Dangerous Occupation
A horse farrier of 45 years was trimming the hooves of the defendant's horses when the
horses knocked the farrier down, causing him to strike his head on a rock. The farrier
died from his injuries. His widow sued the defendant for premises liability and wrongful
death, alleging that the defendant had negligently allowed his corral to remain rocky,
thereby contributing to her husband's death. The trial court granted summary judgment
for the defendant, finding that the horses, not the rock terrain, caused the fall. The court
found that the defendant owed no legal duty to the farrier because of the "occupational
assumption of risk doctrine." On appeal, the court affirmed, ruling that a no-duty rule (often called the
"veterinarian's rule") applied where a person confronted unpredictable animals as an inherent part of his job.
The court found that the job of a farrier was an inherently dangerous occupation as much (or more so) as that
of a veterinarian. As such, the assumption of the risk doctrine applied to bar the widow's claims. The
defendant owed no duty to the farrier since the farrier assumed the risks of his inherently dangerous
occupation and all of its associated risks. Barrett v. Leech, No. D063991, 2014 Cal. App. Unpub. LEXIS 5185

Water for Your Horse
by Equi-Analytical
Water intake influences fluid balance, temperature control, exercise
tolerance, and digestibility of feedstuffs. A horse consumes about ½
gallon of water for each 100 pounds of body weight every day. Water
demands increase with hot and humid weather, increased workloads,
during lactation, and even when being fed coarse hay or pasture.
If you are using a municipal water supply, the municipality is testing
water for contamination such as bacteria, toxic chemicals, and
radioactive materials. However, there could be problems with the
system delivering water to your farm or the pipes at your farm could be
a contamination concern. If your water is from a well, you are
responsible for any testing.
In general it is a good idea to test the water on the farm at least once a year. Other times that you should
take a water sample are:
- If you have a noticeable change in the color, odor, or taste of the water
- Any animal or person drinking the water becomes sick
- The water supply has been disassembled or a new water source is added to your system
- Flooding occurs around or near your well
- The cap or interior of the well has been damaged.
What to test for
Coliforms - A test for the level of bacteria in the water that are normally found in soil, surface water, and
human and animal wastes. Coliform bacteria are not generally a problem, but high coliform counts indicate
that the water may be contaminated with animal or human waste, soil, or decaying vegetation. When present
at high levels it is likely that pathogenic viruses, bacteria, and protozoa may be present.
pH - Water should be in the range of 6.5 to 8.5. If the pH is acidic (less than 5.5), reduced feed intake can
occur. Highly alkaline water (over 9.0) may cause digestive upsets and diarrhea, and reduced intake of feed
and water.
Hardness - Associated with high concentrations of calcium and magnesium. This is not generally a health
concern, but can be a problem for water systems and when washing animals or equipment.
Nitrates - Nitrates in ground water can be a concern for livestock production and human consumption. Nitrates
in water are generally related to timing of fertilizer or manure applications and leaching from manure storages
or piles. Horses are tolerant up to 450 ppm, while toxic levels for humans are in the 45 ppm range.
Other - Water analysis will generally include the concentrations of calcium (Ca), magnesium (Mg), sodium
(Na), iron (Fe) and sulfates. All of these can cause changes in color or taste if present in high concentrations.
Our lab offers a wide range of water testing options. You can order water sampling kits and find the water
