An Exmoor pony breeder recently contacted EPIC and asked if we could raise
the issue of worm control in ponies grazing conservation sites. Also the
news came to light of a warden who unfortunately lost two ponies on his
reserve. The postmortem revealed extensive worm damage. An easily
avoidable loss.
We obviously therefore should not be complacent and all need to look at this
in more detail. Variables such as grazing ratios and the nature of the
ponies ( ie. age, whether handled or not etc.) need to be considered when
devising the most effective worm prevention programme as part of good
management practice. It should be remembered that an Exmoor, just like any
other pony, cannot make the best use of the available food source if
carrying a heavy parasitic worm burden. Even one older pony who may be
resistant to some extent to the effects of worms it is carrying itself and
appears to be in good condition, will be a constant source of infection to
the pasture, and the rest of the group.
Routine worm dosing, veterinary analysis of faeces samples, management of
the pasture to minimise the spread of eggs, (can eggs be introduced on the
soles of the boots of the many walkers who visit reserves??), biological
control and prevention and the risk to the invertibrate population from
using certain types of wormers are just some issues about which graziers
need information and practical advice.
Have you something to contribute to this debate?
