it becomes a more useful commodity as it can a substantial
source of nutrients, containing 10 percent crude protein,
about 10 percent sugar and a substantial array of fibers. The
latter include mainly celluloses, hemicelluloses and pectins.
Pectin concentration can reach up to 20 percent of dried
sugar beet pulp, making it a most interesting fiber. It is often
speculated that the high swelling (water holding capacity)
exhibited by dried sugar beet pulp is mostly due to its high
pectin concentration. A close look at the table presented in
this article will demonstrate that pure pectin (from apples)
is not as strong as in holding water as sugar beet pulp fibers.
This is perhaps due to the different pectins among the two
sources, or an interaction of different fibers within sugar
beet pulp. At any rate, dried sugar beet pulp remains the
strongest raw material in terms of water holding capacity.

Wood fiber (lignocellulose)

A most unlikely source of fiber, wood fiber (lignocellulose) has become almost a commodity nowadays. It is
mostly, but not exclusively, made of celluloses, hemicel-

luloses and lignin. This ingredient is highly hydroscopic
(absorbs water), but not to the extent of sugar beet pulp.
It also offers other fibers, as well, and most importantly a
variety of phenolic compounds that can exert antioxidant
activity. The most pronounced benefit of this novel source
of fiber is that it is a wholesome (not purified), yet concentrated source of functional fibers. Thus, it is preferred by
premix manufacturers who are always pressed for space in
their product formulations.

Take-home message
Today, we have breached the wall of crude fiber that
kept everything ensconced in a black box. Ruminants led
the way, but monogastrics have not benefited from such
knowledge as the antibiotic-free era have forced nutrition
thinking to delve into biological aspects. We have done
most of the qualitative work, that enabled us to create a
modus operandi. What we now need is a final push to
obtain quantitative data that will transform all these data
into practical feed formulation techniques. ■
