If Living Out
Worm your horse with the product suitable for the time of year.
To help sterilize contaminated pasture, harrowing when it is hot and dry may help.
If possible remove dung from the fields twice a week.
If you stable your horse to administer worming products and then return the horse to the same field, there is no point in keeping him/her in after worming (he/she is no more infective just after worming than he/she was before). However with certain products there are special precautions to be observed.
Administer the wormer then leave your
horse in the stable for 48 hours. Afterwards, remove everything that could be
contaminated (bedding, hay etc) then clean the stable and contents with a
strong disinfectant. Next,
bring in some fresh bedding and forage; once they have been brought in the
horse can go back into the stable.
It is good stable management to
regularly clean all feed and water buckets. A good worming programme is always made more
effective by good management.
Remember that any change in circumstances and management may upset your horse and in some cases lead to a bout of colic, particularly if your horse is used to grass and then suddenly gets stabled, so in general situations stabling is not necessary. It is best that your horse does not associate worming with a sudden change to their life style.
As a general rule, new arrivals on a yard that have arrived with a satisfactory worming history should be treated with the appropriate products. These can include small redworm, redworm and tapeworm treatment, where possible they should then be turned out on to a paddock that is especially reserved for this purpose. If there is no established worming history then any doubts about how to commence a worming programme should be referred to a vet.
New arrivals on a yard will bring new worm burdens with them so there is a case for stabling them for 48 hours before letting them graze with the rest of the herd.
