Resumen
Farming
of
European
wild
boar
(Sus
scrofa
L.)
for
meat
production
has
been
increasing
over
the
last
few
years
in
countries
such
is
Chile,
due
to
particular
organoleptic
characteristics
of
the
meat
and
its
low
fat
contact.
The
majority
of
the
animals
are
farmed
using
a
pasture-‐based
grazing
system
and
receive
a
supplemental
diet.
Previous
studies
that
have
aimed
to
determine
the
nutritional
importance
of
pasture
have
been
carried
out
on
young
animals
over
a
short-‐term
period
(4
weeks).
This
study
aimed
to
determine
the
proportion
of
the
total
digestible
energy
(DE)
intake
that
pasture
represents
in
the
diet
over
the
entire
growth
period.
The
pasture
and
supplemental
diet
intake
of
six
three-‐
month-‐old
European
wild
boar
was
determined
during
one
day
every
two
weeks
through
the
5-‐month
long
growing
period.
Throughout
the
study
the
animals
grazed
for
8-‐hours
daily.
Following
the
grazing
period
the
animals
had
free
access
to
a
supplementary
diet
(3.4
Mcal
DE,
0.8%
lysine)
for
one
hour
and
were
then
housed
in
a
barn
during
the
night.
On
the
days
that
pasture
intake
was
determined
for
each
animal,
they
grazed
small
areas
and
pasture
samples
were
taken
at
ground
level
pre-‐
and
post-‐grazing
to
determine
their
pasture
intake.
On
the
same
day
the
supplemental
diet
intake
was
also
determined.
The
DE
content
of
the
consumed
pasture
was
determined
based
on
the
botanical
composition
of
the
pasture
and
previously
determined
DE
values
for
the
different
pasture
species
in
the
wild
boar.
Overall,
over
the
entire
5-‐month
period,
pasture
consumption
accounted
for
15.3%
of
the
total
DE
intake
of
the
animals
(total
intake
=
DE
intake
from
pasture
plus
that
from
supplemental
diet).
Pasture
makes
a
significant
contribution
to
the
energy
requirements
of
grazing
growing
European
wild
boar.
