There is appreciable
evidence that feeding hydrated
sodium and calcium alumino
silicate such as Novasil may
partially reduce the adverse
effects of aflatoxin in the diet
and levels of aflatoxin found in
the milk of animals fed conta
minated feed.
Depending upon the level of
mycotoxin in the total diet diy
matter, the aluminosilcate may
not reduce aflatoxin in milk to
legal maximum levels for
human use. Apparently alumi
nosilicates absorb the aflatoxin
and increase its excretion via
the digestive tract. Sodium or
calcium bentonite also has been
shown to reduce effects of afla
toxin on health and
performance.
Unfortunately, there is of yet
little research evidence which
indicates that aluminosilicates
or bentonite are effective in
reducing effects of other myco
loxins upon animal perfor
mance or health. Therefore,

7. Dilution with non
contaminated grain is a good
bet if mycotoxin levels aren’t
too high. For example, vomito

50 ppm. If you reduce that com

Feed Additives
you should not depend on these
additives to alleviate problems
with other mycotoxins, espe
cially those produced by Fusar
iums, which are apparently
more prevalent under North
eastern conditions and more
likely involved than aflatoxin
in performance and health
problems.
Effective levels of alumino
silicates and bentonite range
from .5 percent to 1.0 percent of
the total ration dry matter. The
lower level of .5 percent has
been of value with aflatoxicosis
in swine, while 1.0 percent has
reduced aflatoxin in milk by 25
percent to 44 percent in- some
research.
Since no harmful effects
have been noted at these
intakes, these fairly inexpen
sive ingredients could be
included even in diets with
appreciable mycotoxins other
than aflatoxin present. Howev
er, their use should not negate
the probable need to reduce
levels of contaminated feed in
the diet, or at least temporarily
discontinue feeding items with
appreciable mycotoxin or mold
content to alleviate problems or

mycotoxins will be contained
in these components. For some
producers, it may be tempting
to buy “screenings” from feed
and flour mills since the price is
attractive. But if the grain was
cleaned after a hot and dry, or
excessively wet growing sea

SUMMARY
If test weights and protein
levels from grains grown under
these conditions arc normal,
then the grain may be OK. If a
chemical test shows the grains
are negative for mycotoxins,
then it’s even a safer bet that the
grain is usable.
But you can never be sure
until you feed it. If you see any
of the following symptoms in
your pigs, be suspicious of
mycotoxin poisoning.
• Feed refusal
• Swollen vulvas
• Prolapsed rectums or
vaginas
• Convulsions
• Death
• General reduction in
performance.
