Wild King: High-Welfare Pork from China
Cross-breeding and a high welfare approach are providing a workable alternative to intensive pork production in China, according to a Model Farm Project by Farm Animal Initiative (FAI).Intensive pork production
in China is associated with
a variety of problems.
“The
main issues in terms of animal
welfare are high stocking
density, tail docking, tooth
clipping and – for breeding pigs
– confinement in farrowing pens
or sow stalls,” explains Dr Ashleigh
Bright of the Model Farm Project (MFP).
As well as affecting the
animals concerned, these are
a becoming a growing issue
for those buying the pork.
“Poor animal welfare, use of antibiotics, contamination of
feed and the environmental
impact of animal waste are all
of concern to consumers,”
says Dr Bright. “Traceability
is a big one, too.”
* "I believe that good animal welfare and a happy, healthy environment will produce good pork." |
Consumer concern is just
one reason why pork farmer
Bob Wang of Wild Pork
Kingdom has
developed a higher welfare
approach.
He said: “I believe that
good animal welfare and
a happy, healthy environment
will produce good pork. If your environment has too much
pressure and is overpopulated,
it’s easy to be stressed. Like
people, pigs will
also be affected
by stress in an
overcrowded
situation. It
isn’t necessary
to tooth clip or
dock the tails
of my pigs and
I believe this is
because they live in a stress-free
environment.”

Wild Pork Kingdom: the approach | Benefits |
If it is sow’s first litter or sow is >50% wild blood, farrowing crate is used (L:1.82–2.08 metres, W:0.6 metres, H:0.83–1.04 metres). Experienced sows placed in pens (L:3.42 metres, W:1.84 metres, H:2.5 metres) with concrete floor and one to two inches of hay during winter. | Piglet mortality in first litters is reduced as sows
are prevented from rolling onto piglets. Mr Wang
is also looking at other ways to reduce piglet
mortality.
Concrete floor helps sows keep cool in summer and sows can use hay to build nests and keep warm in winter when temperatures can reach -18°C. |
Sow and piglets moved to seven- to eight-square metre pen with concrete floor, access to 14– to 16-square metre yard and one to two inches of hay during winter. | Piglets can access outdoor area and play with other piglets. |
Piglets weaned at four to five weeks and moved to pens
in groups of 20 to 40, remaining there for for weeks.
Pens have concrete floor with one to two inches of hay.
Piglets typically in outdoor yards (400 square metres per pen)
during daytime with access to shade.
Sows moved to deep litter pens (L: 35 metres, W: 3.5 metres) or to around 32-square metre dry pens with access to outdoors. |
Straw provides manipulable material and outdoor
yard enables pigs to root in soil and create wallows.
Deep litter pits provide warmth and waste from the pits is given to neighbouring farmers to fertilise crops, in exchange for use of land and feed. Dry pens are cooler in summer. |
At 15–20kg, piglets moved into grazing paddocks (800–2,000 square metres) with 80 pigs per paddock. Five grazing paddocks used in rotation. Pearle Kings remain here for four to five months and Wild Pearles for six to 10 months. Both finished at around 80kg. | One area rested while others used. |
Pigs fed corn, wheat and alfalfa twice daily, quantities varied according to life stage. All feed grown on site or sourced from neighbouring farms. Vitamins, minerals and trace elements (selenium, zinc and copper) provided while sows feeding piglets. Water provided via farm’s 370-metre deep well. | Sows can chew and are therefore kept occupied. Sourcing locally reduces feed miles and means farmer and consumers know where and how feed was grown. |
The Farm
Wild Pork Kingdom is an 8.3-hectare pork farm in Cangzhou
City in Hebei Province, China,
where Mr Wang has bred Beijing
Black pigs (Wild Pearle) and
Changbai Mountain and wild
pig cross (Pearle King) sows
since 2007.
The farm also grows
alfalfa, planted four to five times per
year and used as feed along
with locally sourced corn and
wheat, all grown without the
use of pesticides, herbicides or chemical fertilizers.
Raised in this
stress-free environment, pigs are
healthier, with strong immune
systems where antibiotics are
only used therapeutically.
The Wild Pearle is classed as
a ‘fat’ breed and the Pearle King
is a ‘lean’ meat breed, so when
the two are crossed, it gives us
a good quality meat,” explains Mr Wang.
Hardiness is another big
plus.
“Once Wild Pearle and
Pearle King piglets reach 20–25kg, they are able to
handle very cold temperatures
– in winter, temperatures can
reach -18 degrees,” explains Mr Wang. “No
commercial pigs can handle this.”
Mr Wang uses an ‘open grazing’
approach, incorporating different
types of pen suited to varying
life stages. Deep litter pits are
also integrated into the system.
The Results

While there is no formal
monitoring, Mr Wang has
observed low levels of tail biting (see Table 2).
“There is absolutely
no docking but there are always
one or two naughty pigs in the
paddock that will bite each
other’s tails,” he says. “Only
the piglets of the sows placed
in birthing cages have their
teeth clipped.”
Piglet mortality
is higher than may be expected
in a typical intensive system
due to free farrowing, i.e. more
piglets are getting crushed
by the sow. This is an issue
Mr Wang is working to address by
selecting his replacement sows
from mothers which do not crush
their piglets and have piglets
with a low mortality rate.
Mr Wang
has also employed an on-farm
veterinarian to assist with health
planning for the production cycle.
Table 2. Outcome measures at Wild Pork Kingdom (annual averages) | |
---|---|
Outcome measure | WPK data |
% of animals tail docked | 0% |
% of tail biting incidents | ~1% |
% of animals tooth clipped | <10% |
Mortality of pigs born alive | ~15–20% |
Adult mortality | ~1–2% |
A total of 12 staff currently
work on the farm and are
provided with free accommodation, meals, uniforms and education
regarding animal welfare.
Mr Wang is pleased with the
approach – and final product.
“Anybody who tries my pork will
say it is delicious,” he says.
Potential for Growth
Demand for pork is high
and Mr Wang has plans for
expansion. In 2012, he will finish
around 1,000 pigs and began selling
to a ‘high level’ supermarket in
May.
But Mr Wang intends to build
on this; he aims to be finishing
up to 4,000 pigs in 2012 and
up to 8,000 in 2013, selling
direct to customers, agents and
companies.
“I also hope to sell
direct to schools and to teach
kids about animal welfare,”
says Mr Wang.
He plans to increase the
number of grazing paddocks
for piglets from five to 11, at
4,082 square metres each, with pigs kept at the same stocking density.
The farm will trial birthing arks
this spring, which allow the
sows to perform more natural
birthing behaviours such as
nest-building and provide an
enclosed sheltered space for
farrowing.
Mr Wang also hopes to
improve the slaughter process.
“According to Chinese law, we
can’t kill pigs on our farm but
transportation causes stress,”
he explains. “So I hope we can
work with organisations such
as FAI and WSPA and research
animal welfare issues at the
slaughtering stage.”
