requirements for growing pigs
Straw finishing systems
recommendations are one 95 kg liveweight to each 1.4 m2 (15 sq foot)
(straw usage about 3 kg/head/week)
A 100 kg pig requires 0.93 m2 (10 sq feet ) to ensure
that it does not touch another pig –
a requirement when it is too hot
Finishing pens should not be narrower than 2.5 m width
Ensure pens are not too long and narrow or increases in lameness
will occur
More than 60 pigs in a big pen is required to create a tolerant
social structure
Area occupied by the pig (m2) = kW0.67 with
k ideally = 0.05
For every 0.1m2 reduction of ideal space results in a 5%
reduction in feed intake
Individual living
accommodation for
an adult boar should have a floor area
of not less than 7.5 m2
(81 sq ft) EU 6m2 (64.4 sq ft)
Pens used for living
and service should not be
less than 10 m2 (108
sq ft)
with the shortest
side not less than 2.4 m (8 ft).
Boar pen divisions
should not be less than 1.5 m
(4ft 11 in) high
Boar stalls – 0.7 x 2.4 m
Total unobstructed floor area after breeding for each gilt to be at
least 1.64 m2
Total unobstructed floor for each sow and gilt in groups to be 2.25 m2
If gilts or sows are kept in a group of less than 6 space needs to
be increased by 10%
If gilts or sows are kept in groups of more than 40 then the space
may be decreased by 10%
Total slatted areas are banned with at least 0.95 m2 for
gilts and 1.3 m2 for sows to be solid with no more than 15% of the
solid area reserved for drainage openings. – Jan 2003
To maximise heat
detection a floor space of
2.8 m2
(30 sq ft) is recommended
Internal area of a stall or pen not less than the square of the
length of the pig (sow 2m long) – 4 m2
If free access stalls back onto a solid wall: space between back of
stall and wall at least length of pig
Free access stalls and back to back with central pen minimum
distance between of 3 x length of pig from front of stalls with a 1.5 gap
between the ends of the stall
The escape
area around a
farrowing crate should be 300 mm
wide (12 in)
Heat mat minimum 0.6m2 (4ftx1.5ft) Farrowing arc should have a floor area of
4.5 m2
Farrowing crate and creep area – 0.5 x 2.02m (AU) – flow area 3.2 m2
Farrowing pen –
shortest side a pen should be 1.8m length, total area of the pen no less than
5.6m2 per sow
15-25 sows per hectare (6 to 10 per acre) 20-25 (AU)
9-14 sows/ha farrowing (AU)
33 Service area, 27 Dry sow, 19 Farrowing per hectare
235 kg/m2 for transport.
This is the EU 95/29 limit for 100 kg pig requirements
281 kg/m2 is the MLC guideline. A slope of < 20º suggested for loading ramp
