Feeding
- Pigs are monogastric animals and can utilise fibrous
food only to a limited extent. Adult pigs can utilise fibrous food better than young
stock.
- Part of the protein in the diet of pigs should come
from animal source such as fish, meat etc.
- Pigs should be fed at regular intervals.
- Fresh feed should be put only after removal of the previous
feed from the feed trough.
- Pig rearing based on commercial pig feed is not economical
and hence feeding based on swill is recommended. On an average, pig requires 4-8
kg swill per day.
- All categories of pigs can be given small quantity of
fodder or may be sent to pasture.
- Ad libitum feeding using an automatic feeder (which
can be fabricated using 200 litre oil drum) may be practiced for weaned pigs to
avoid post-weaning weight depression.

Miscellaneous feeds which can be fed to pigs:
Swill (kitchen waste including left over of human food, vegetables, meat and
fish cuttings): Composition and quantity vary so greatly that it is difficult to
indicate feeding values. It has been observed that pigs weighing 30 kg reached a
body weight of 70 kg in 70 days when fed exclusively on kitchen waste. Ensure that
swill feed is not old and putrified. On an average 4 – 8 kg swill is needed per
pig per day.

Feeding of boars
A breeding boar requires 2-2.5 kg concentrate per 100 kg weight depending on the
age, condition and breeding demand. Feed allowances should be so adjusted that the
pig is neither fatty nor run down. Greens should be provided if kept indoors. Year-round
pasture is excellent if it could be provided from the stand point of providing both
the needed exercise and valuable nutrients.
Feeding of female
The demands resulting from pregnancy and need for conserving nutrients for ensuing
lactation are accelerated during the later third of pregnancy. The increased needs
are for proteins, vitamins and minerals.
Mature sows gain 30-35 kg and gilts 40-45 kg during pregnancy. Feed should be so
regulated that sows and gilts are never over fat or thin. Individual feeding is
preferred.
Flushing is a practice of giving extra feed to sows and gilts from 1-2 weeks prior
to mating and returns to normal feeding after mating.
Feeding of Farrowing
Sow and Litter
Feed lightly with bulky laxative feed immediately before and after farrowing. Bring
the sow to full feeding in 10 days. Plenty of greens may be provided. Feed allowance
may be calculated as 2.5-3 kg/100 kg body weight plus at the rate of 0.2 kg feed
per piglet with the sow. Thus, a sow weighing 100 kg with 8 piglets should receive
4.6 kg feed per day. The piglets may be provided with special nourishing diet called
creep feed separately
Creep feeding:
The practice of self-feeding concentrates to young piglets in a separate enclosure
away from their mother is known as creep feeding. Creep feed should be given when
piglets are two weeks old. Each active and healthy piglet may consume about 10 kg
feed before reaching the age of 8 weeks and two-third of this consumed between 6-8
weeks.Feeding of growing and finishing pigs
The pigs may be given complete feed they can consume to attain maximum growth. Alternatively,
they may be fed a fixed quantity twice or thrice a day. Yet another method that
they may be fed all the quantity they consume within a fixed time of 30-45 minutes
or so.
On an average, the post-weaning feed conversion efficiency till market weight may
be about 4 i.e. this much quantity of feed would be used by the pig to gain one
kg of weight. However, it varies considerably with age and ambient temperature.
Protein requirements are greater during early life. As fattening progresses, protein
per cent in the ration may be decreased.
