These little bugs can carry diseases-- to people as well as other animals.
Ticks will cause severe anemia in animals if they are of heavy burden.
Last year the standard treatment with Atroban didn’t effectively work… This year I suggest that you use the Permectrin CDS product. This product has an oil base so it can be poured or wiped on (follow label instructions. This product also can be used for fly control later in the season.
Genetically, our horses exceed our environment, therefore, we need to supplement them with minerals and seasonally, we need to supplement vitamins.
A year around supplement is ideal to meet their needs. The best mineral that I have found do this is the loose mineral (Equine Bio-Mineral) from West Feeds (now called Ridley, Hubbard). This mineral is different from most available minerals in that it has chelated zinc, copper and manganese. These mineral are key to health (I notice improvement of foot and teeth density, improved reproduction and wound healing). When supplementing this mineral remove the salt, the mineral has a baseline of salt in the formula. This mineral is designed to be offered free choice… if the consumption is higher than recommended for more than 2 weeks then loose salt can be added to regulate intake. We order this mineral by the ton, it is packaged in 25 pound bags. The cost per year is about 50 to 80 dollars per horse—a good investment.

Winter Vaccines:
Most people wait to vaccinate their horse(s) in the spring…
• This will be too late if the horses are out and exposed to other horses.
• It takes about 2 weeks for immunity to form from vaccines.
• Exposure at barns and events will transpire prior to spring.
• Some horses carry the Rhino (herpes) virus for a lifetime.
• Some horses and facilities harbor the strangles bacteria.
• Your horse needs to be 20 ft. from a shedding horse (cough) to be out of range of aerosol exposure.
Vetera 2XP is a 2-way vaccine that applies to our horses that are exposed to non-resident horses; e.g. horses that are used in events, attend brandings, trailer or board with other horses. This vaccine contains Flu & Rhino. The time to give it is 2 weeks prior to exposure to other horses… now.
Pinnacle vaccine (strep/strangles) is an important vaccine for exposed horses. This bacteria can be persistent in some horses and facilities. I suggest the initial 2 dose series in all horses then thereafter boost only if they are going to places that have a history of this infection or if they are exposed to this problem.
Spring Vaccines:
Endovac Equi is a vaccine that helps horses that founder on green grass. This salmonella vaccine
produces antibodies that tend to lessen the toxemia that occurs in some of our green grass sensitive
equine. The appropriate time to vaccinate is April. It takes several weeks for the vaccine to produce the
Vetera EWT + West Nile is a 4-way vaccine that all horses should get if they don’t receive the 6-way.
This 4-way vaccine protects our horses from serious illnesses that can occur even if the horses are
isolated. Sleeping Sickness and West Nile are transmitted by insects and Tetanus is a common soil
bacteria. The time to vaccinate with this product is the middle of May.
Fecal evaluation or deworm?
Traditionally, we have instructed you to deworm your horses on a regular schedule. Times are changing
due to scientific advancements in the understanding of internal parasitism:
• Worms are developing resistance to our deworming products.
• Individual horses have different immunity to worms.
• Horses have different risk and exposure to parasites.
• Deworming products are not all equal and should be selected based on the type of worms
Fecal flotation is the technique used to evaluate internal parasitism. It is simple to obtain a sample and
submit it to our hospital (a couple of fecal balls in a zip-lock bag with the horse name is an adequate
sample). We can do this test in-house and our doctors can recommend and appropriate product and
proper program to maintain internal health in our horses. The time to do this is now!
Reproductive preparation:
Some of you have plans to breed some mares this spring. Considerations that are timely are:
• Nutritional preparation for fertility
o Vitamin/mineral supplementation
o Proper body condition
• Photo period influence
o As the length of daylight increases our mares will begin to cycle. The first cycles are
often infertile and are called “transitional”. Breeding a mare in these cycles can be
confusing and frustrating. Ultrasound and palpation can distinguish if fertility is present.
• Pre-breeding exams are important. Whether you are using live cover (stallion) or artificial
insemination (AI), breeding horses involves time and money. Some mares have issues that can
be identified and possibly addressed to achieve your goal of a healthy pregnancy. These exams
should be done in advance of breeding and the procedure may vary based on history and health
of the mare.
• Synchronization is a good management tool whether you are inseminating or live covering
mares. Controlling the cycle of a mare often lessens the cost of breeding. If you have specific
questions on this process give us a call. 406-265-8901
• Our standing thoroughbred “Athlete” is available and would cross nicely on quarter horses to
create an appendix breed. This cross typically yields a bigger, athletic horse.
The purpose of this letter is to help guide you in the care of your horses. Product selection, timing and
proper administration is critical to our horses health and productivity.
