Abstract:
Compared with the traditional p
ig
raising, pigs in this healthy pig-raising
craft
were raised on a biological bed spread by or
ganic
bedding with a thickness of 0.8 cm adding in
the
pig houses built accoding to the require
ments
of healthy pig-raising craft on bio-be
d.
The pigs were raised from 25 kg to 90 kg. Th
e
results showed that under the healthy pig-rai
sing
craft, the growth rate increased by 12.2
%~14.5%; the consumption of forage decreased by 8.1
%~10.8%; and the breed efficiency of fatteni
ng
pigs increased by 31.56%. The develpoment
and
health of pigs was improved remarkably. Th
e
amount of excrement decreased by 2.88%; and th
e
contents of nitrogen, calcium and phosphor
us
in the excrements decreased by 49.75%, 46.
15%,
27.97%, respectively, thus accomplished
the
reduction of emissions. T hrough ferment
ation
and degradationof the excrements by mi
croorganisms
in the bedding, it could be reg
arded
as
“zero release”, and no pullution to th
e
environment. But the microenvironment cli
mate
and health situation of the pig houses were relati
ve
bad.
