Rice bran is a misnomer, or rather a confusing
term because it can encompass a range of rice byproducts at variable concentrations. But rice bran
it is, and this name has prevailed in literature
and commerce. It is a very atypical ingredient: it
has excellent nutritive value, but it is undervalued by most nutritionists; it is widely available,
but hardly traded in the commodities market.
Understanding how rice bran is produced and
its problems will help nutritionists seek out this
eccentric ingredient and use it in pig and poultry
diets with confidence.

The rice milling process
It all starts with rice grain as it arrives from
the field. The rice we grow and the rice we humans eat do not look the same. Field rice comes
with a tightly attached outer husk or hull, very
much like barley and oats. Removing the hulls is
the first step in the rice milling industry. Unlike
other similar cereals, rice has hulls extremely
rich in silica (silicon dioxide), better known as
quartz or sand. As such, rice hulls are immensely
abrasive not only on the feed mill machinery, but
also inside the animal.
