such as lead, arsenic, and others. Prof Ivan Horak
and co-workers did a controlled experiment to
test the efficacy of diatomite on ectoparasites, but
they came to the conclusion that clean water was

Having read some of the answers, would it not be
beneficial to rather sell them poor man's lucerne

the dried lucerne and mix it into their rations for
sheep. At least there is some evidence that this
works against worms...

I have observed many game species at times eat
plants that are normally considered unpalatable
for example high tannin content (wattle trees)

Two years ago we had a workshop, "What
Works With Worms" under SAVA auspices and
including a number of internationally respected
parasitologists like Jim Miller of Louisiana SU,
who reviewed the available literature on DE for
its effects on internal parasites. His conclusion
was the same as that of Joop, at best its effect
is very little, far below what is required for our
registration. A local investigation conducted by
Faffa Malan, Jan van Wyk and me many years ago
yielded the same conclusion.
Whatever its virtues, worm control is not one of
them. Maybe its a case of " it does not work, but it
soothes the conscience "?
