VEGETABLE PROTEIN SOURCES
tion. Peanut meal is considered an appetizing ingredient
for monogastrics, perhaps due to its residual oil concentration (about 1 percent). Peanut meal contains about 50 percent crude protein of good digestibility value, and a few
anti-nutritional factors (mainly trypsin inhibitor activity)
similar to soybeans, most of which are neutralized during
the extraction process.
The main limitations in the use of peanut meal are the
level of fiber that is a result of the manufacturing process
and  the presence of mycotoxins (mainly aflatoxins). As
peanuts grow in the soil, and usually in warm, moist climates, the amount of mycotoxins can be relatively high.
The only solution remains quality control at the receiving
factory excluding batches with a high degree of contamination. Ammoniation and aflatoxin binders in the feed are
the second-best alternative. Otherwise, peanut meal can
be used relatively freely in diets for broilers, even in the
first diet post-hatch.

Guar gum meal

Guar is a legume, widely cultivated in India
and Pakistan, and also in certain parts of the
U.S. and other countries. Its main use is for the
production of mannogalactan gum, a binder for the paper and
pigments industries. The residual meal after the extraction of
the gum contains 50 percent crude protein. The main antinutritional factor is the residual gum, which can be addressed
- potentially - with the addition of a suitable enzyme.
Field trials have yielded variable results, most likely due to
wide variations in quality. Until more information is available
to better qualify the properties of guar gum meal, a conservative approach is recommended in its use in broiler diets.

Lupins
Lupins are grown primarily in Australia and
can become available in certain parts of Asia.
They are also grown in UK and Canada. Lupins
