contain 32 to 42 percent crude protein (depending on cultivar), of value comparable to that of soybeans. Their main
limitation is the level of alkaloids, which has been reduced
markedly in modern sweet lupin varieties. Otherwise,
lupin inclusion levels in broiler feeds are reduced by the
remarkably high level of crude fiber (25 percent), a good
part of which is pectins that cause increased gut viscosity, that leads to low energy concentration. The problem
of high crude fiber concentration can be alleviated by
dehulling, fine grinding, and perhaps with the addition of
suitable enzymes. Lupins, unlike soybeans, do not require
thermal processing before being fed to animals.

Sesame meal

In general, sesame meal is not widely available. It does not contain major anti-nutritional
factors, except for high levels of phytic acid. It
also contains very low levels of available lysine, but it is
a good source of methionine, something that is used to
advantage by organic poultry producers. The amount of
sesame hulls added back to the meal will also affect its
quality. In general, upper inclusion levels are not well understood for poultry, and sesame meal should be used with
moderation, especially when it comes to phosphorus and
calcium dietary specifications.

Significant savings
The list of possible alternatives when it comes to soybean meal cannot be exhausted with the seven ingredients
discussed here. There is a great plethora of agro-industrial
co-products and minor crops worldwide. Each has its
own potential and limitations. A conservative approach
is needed when dealing with an unknown ingredient, but
when a qualified nutritionist is armed with suitable laboratory analyses of the protein source at hand, a more liberal
inclusion of such proteins can lead to significant savings.
In general, it is advisable to keep all such alternative
proteins away from the first diet post-hatch - not only do
young birds benefit from superior protein sources, but real
cost savings are better realized towards the later production phases when feed intake is at its maximum. ■
