War On Worms
Parasite infection leads to colic, the number one
killer of horses!
It is a proven fact that there is a significant linkage
between parasite infection and the incidence of equine
colic. Horses are infected with over 30 different types of
strongyles, in addition to ascarids, pin worms, and bots.
The most damaging and difficult to control is the strongyle
parasite while in the migratory stage. Its life cycle is
clear cut. A horse passes the eggs in its feces, and in one
week the larvae hatches and becomes infectious. While the
horse grazes, they are continuously ingesting the infectious
The immature form of large
strongyles or “bloodworms” spend between two and nine months
traveling throughout the body. During this migratory
pattern, they burrow into the intestinal wall, liver, lungs,
and blood vessels. (They especially like to burrow
themselves into the interior mesenteric artery which
supplies over 70% of the blood to the intestinal tract).
While burrowed, de-wormers/anthelmintics are unable
to eliminate them. Thus, they
are able to cause temporary or permanent damage to your
horse’s intestinal organs.
The physical signs of worm
infestation are: diarrhea, abnormal bowel movements, long,
dull hair coat with irregular shedding patterns, poor growth
rate due to improper utilization of feed or nutrients, and
breathing problems due to lung damage or pneumonia. Colic
symptoms whether due to worms or not, are abnormal bowel
movements, increased pulse, sweating, and restless rolling
or pawing. By the time you see any of the above symptoms the
worms have already caused the damage.
It’s important to know
that 90% of colic cases are caused by the damage of worm
larvae migration, and 30% of the fatal colic deaths are
caused by damage from migrating large strongyle larvae. This
information should help us understand the need for a
rigorous de-worming schedule implemented by a veterinarian
who understands the life cycle of worms, in addition to the
appropriate dosages of effective anthelmintics.
A structured tube
de-worming program is essential in order to protect your
horses against worms. A proper de-worming program, along
with (FEC) fecal checks, break the worms life cycle, reduces
environmental contamination, and prevents the worm
population from becoming resistant to anthelmintics.
There are more than 150
internal parasites that afflict horses. Some species lay
more than 20,000 eggs per day, which result in escalating
parasite loads. Each parasite is harmful to your horse in
many different ways.
Based on our extensive
knowledge, we believe horses should be on a strategic
de-worming program. We recommend having your horses
TUBE DE-WORMED two to four times a year and paste de-wormed
in between if the (FEC) indicates it is necessary.
When Dr. Winter tube de-worms, he rotates the class of drug
and administers an appropriate amount of wormer directly
into the stomach.
This structured de-worming program will maximize your
horses’ health, performance, appearance, and comfort. This
also allows your horse to efficiently utilize their feed,
thus decreasing your feed cost.
