VEGETABLE PROTEIN SOURCES
Knowing these factors and their concentration can lead to
very successful feed formulations using alternative protein
sources and to very profitable production outcome.

1

Palm kernel meal

The rapid growth of palm oil production in
Asia, Australia, South America and Africa has
led to tremendous quantities of palm kernel meal
being available for all types of livestock. Not a protein-rich
ingredient (less than 18 percent crude protein), palm kernel
meal remains an interesting ingredient because it can contribute to significant cost savings. It is poor in lysine and
methionine, with average digestibility values, but it contains
sufficient energy to constitute a good part of the total dietary protein fraction. It is also relatively high in crude fiber
(up to 20 percent). In many aspects, palm kernel meal can
be compared to corn gluten feed. It is speculated that any
adverse effects of palm kernel meal observed in broilers are

due to its grittiness and overall physical quality aspects and
not due to its nutrient profile. As such, high-quality palm
kernel meal can be used relatively freely, within constrains
imposed by its limited nutrient profile, in broiler diets.

Corn gluten meal

There is nothing really wrong with corn
gluten meal, which is a by-product of the starch
extraction process from corn kernels. It contains
about 60 pecent crude protein, with digestibility values being comparable to that of corn. It also contains the majority
of pigments from the kernel, and it leads to heavy pigmentation of the broiler skin - which can be a desirable or undesirable carcass trait according to market circumstances.
Its inclusion rate is limited by its amino acid profile
(very low in lysine), and its high cost that arises from its
frequent use as a source of natural pigments in layer diets.
In general, it is not advisable to use other corn-derived
