Q. How often should I worm with EQVALAN?
A. Every 8-10 weeks in adult horses and every 6 weeks in young
Q. What else should I do to control worms?
A. The only really effective way of controlling worms is to use
an effective wormer in a planned worming program combined with good pasture management,
such as removing droppings twice a week and not grazing too many horses together.
Resting the pasture or rotational grazing is effective as a way of reducing the
number of worms on the pasture.
Q. Can pregnant mares be treated with EQVALAN Paste?
A. EQVALAN can safely be used during all stages of pregnancy and
in breeding stallions.
Q. How do horses become infected?
A. The cycle of infection begins when roundworm eggs are passed
out in the droppings and develop into immature worms in the dung. These then climb
up blades of damp grass and are eaten by the horse.
Q. What damage do worms cause?
A. Loss of condition such as weight loss, dull coat and lethargy,
loss of performance, diarrhea, colic, and sometimes even death.
Q. Is it true that it is important to worm foals?
A. It is important to worm foals from a young age as they can become
infected with threadworms, which live in the intestines of young foals, soon after
birth usually through the mare's milk. Large roundworms are also important and can
be fatal in young growing foals up to 18 months of age and need to be controlled.
Q. What happens to the worms when they are eaten?
A. Most immature worms develop into adults in the gut of the horse.
Some, however, burrow through the gut wall and into the bloodstream where they migrate
to other parts of the body. It is here, in areas such as the arteries, liver or
lungs, where the immature stages of the worms cause damage.
Q. At what age can I start to treat my foals with
A. If the mare has been wormed shortly before foaling it is recommended
that foals are wormed at 6 weeks of age and are then wormed regularly every 6-8
weeks until they are 18 months old. If large roundworms are a specific problem,
treat foals every 6 weeks over the period of risk. If the mare has not been wormed,
then start worming the foal at 2 weeks of age threadworms. EQVALAN is the only wormer-type
recommended for the treatment of both threadworms and large roundworms at the standard
dose in foals under 4 months of age.
Q. Which are the most damaging worms?
A. Large redworms are the most dangerous but are much less common
than small redworms. The small redworms can be present in huge numbers and usually
account for at least 90% of the horse's worm burden. It is not unusual for horses
to be infected with as many as a million of these parasites. Worms may hibernate
in the gut wall in small cysts. At this stage, they are very resistant to worm treatment.
Q. Is it true that grazing horse with cattle and
sheep helps prevent worm problems?
A. Worms that effect horses do not generally affect sheep or cattle,
so, if you can, graze them together. This will help reduce the numbers of worms
that your horses are exposed to and improve the pasture quality.
Q. Is there resistance to EQVALAN?
A. No, there is no reported resistance. A 9 year trial in the US
where EQVALAN was used every 8-10 weeks for 9 years showed no resistance.
Q. Can I over dose my horse with EQVALAN?
A. EQVALAN is tested up to 10 x standard dose with no adverse reaction.
Therefore it is very safe.
