What do you use for control of brown stomach worms and also external
parasites such as grubs? Do you time grazing to insure that these parasites
are not present in large numbers?
We primarily graze Jersey steers and start them from birth or near to birth.
The young stock would have significant worm loads unless you kept them on
concrete or at least in a confinement facility where feedstuffs were not
contaminated by feces.
Can you honestly say that you have compared gains between animals treated
and untreated for parasites? I am particularly concerned with the young
stock up to 12 months of age.
Do you believe that you are not taking a hit in gain? Or do you view it more
as a trade off? It is well known by graziers who have run actual studies,
that there is a reduction of gain due to the parasite load, even in managed
grazing. I am thinking in particular about Dr. Larry Smith's experience with
his multiyear studies.

Does the NOP consider manure dropped on location by the animal as manure?
This may sound odd to say, but our understanding here in Wisconsin is that
DNR rules tend to ignore manure pats. At least up to a certain point. This
is different than the biohazards that apparently are being addressed in the
NOP, but do they definitely treat spread manure as the same as deposited by

Is it possible to "only" certify one part of the farm operation? Such as
forage production? And not certify other operations on the same farm? I was
under the impression that it was an all or nothing situation. We would have
little trouble certifying our forage since we don't use any pesticides or
herbicides on the forage and no longer do row crops. This does not include
our small market garden which would not be remotely feasible to certify due
to the cost exceeding our net profit.
