that has not had its first offspring Sow- a
female pig that has had 1 or more litters Boar

pig

Swine Overview Production Units
Pregnant sows are kept in individual stalls until
they farrow
13
Swine Overview Production Units
Sows can be individually fed and individual
records are kept on each sow
14
Swine Overview Production Units
Open nonpregnant sows may be kept in group pens
so they exhibit estrus
15
Swine Overview Production Units
Sows farrow litters of between 10-16 pigs, but
can nurse only about 12, excess pigs are cross
fostered to sows that have less than 12 pigs
16
Swine Overview Production Units
Pigs are weaned (removed from the sow) at 18-21
days and segregated into nursery units of equal
size pigs
17
Swine Overview Production Units
Pigs are fed special diets from self feeders and
are moved to larger groups at 7-10 weeks of age.
As pigs grow diets are changed and diets for
gilts differ from from diets of barrows or boars
18
Swine Overview Production Units
Manure from the facilities goes through slotted
floors and is flushed into lagoons the manure is
then used for crop fertilizer
19
Swine Overview Production Units
Buildings may be naturally ventilated with
windows or mechanically ventilated with fans
20
Swine Overview Production Units
Pigs may be fed free choice from self feeders or
feed may be regulated when animals are kept in
individual pens
21
Swine Overview Production Units
A piggy sow is one that is near farrowing, note
the large belly full of unborn pigs
22
Swine Overview Production Units
Boars are taught to mount an artificial sow and
semen is collected so sows can be bred
artificially
23
Swine Overview Production Units
A breeding technician collects semen from a boar
24
Swine Overview Production Units
A breeding pipette is inserted into the sows
cervix and the pipette has a cork screw end that
fits into the cervix, semen is injected through
the tube into the sows reproductive tract
25
Swine Overview Production Units
Boars may be kept in pens close to sows so they
are more likely to exhibit estrus

Swine Overview Future Production
1. Production units will become larger 2. Units
are vertically integrated 3. Export markets are
important 4. Margins will continue to be close 5.
Kentucky will see a decline in hog production
