Abstract
The cattle production systems in the tropic are developed,
basically, under systems of pasturing with
monocultures of grasses, generally with nutritional
contents from mid to low quality, mainly because of
their high content of fiber and low protein levels. As
opposed to this situation it appears the SPS
(silvopastoral systems) under pasturing or cuts and
transportation as an alternative that generally empowers
the total quality of the diet, among other beneficial
factors. The arboreal and shrubs component
involved in these systems presents ample effects
in the nutritional framework of bovines. Their effects
in the animal can be varied, due to the divergence
that occurs in its composition, when compared to
the grasses. This difference occurs, not only at the
primary nutrients level, but also at that of secondary
metabolites (also denominated ANF, or anti nutritional
factors). Traditionally, some metabolites have
been considered anti nutritional factors because of
their negative effects on the fermentative process at
a ruminal level or, in general, on the digestive process
in the total tract. But the effects depend, in
general terms, on the consumption level. Considering
the spectrum of main arboreal and arbustives,
the tropical ones (legumes and non legumes) with
potential in the feeding of the bovines, there are diverse
studied secondary metabolites, such as
tannins, cianogenic glycosides, phytotoestrogens,
saponines and mimosine, among others.
