Care and Management
- The dung and leftovers should be removed twice a day, i.e. morning and evening and
the pen may be washed at least once a day. A pressure cleaning system can be effectively
used.
- Inspect all the animals at the feeding time.
- If the pig is sick or off-feed or unthrifty, remove it from the lot and provide
veterinary aid.
- Check the weight of pigs periodically.
- Put the identification marks by ear notching or tattooing at a very young age and
by ear tags.
- Breeding animals may be given provision for wallowing / water sprinkling during
hot periods. In fattener pigs habitual wallowing lead to slight reduction in growth
rate and feed conversion efficiency and hence wallowing is not essential.

Farrowing Sow and
Litter
- Clean and disinfect the farrowing pen with a solution of 2 % of phenyl lotion and
keep it vacant for a week.
- The pregnant female may be dewormed 2-3 weeks before farrowing and prior to admitting
into the farrowing pen. Spray with external parasiticide (1% solution of malathion/cythion,
butox. 0.05 %). Scrub the under surface, sides, interdigital space and udder to
remove dirt, eggs of parasites, disease germs etc. with soap and water just before
moving into the farrowing pen.
- Move the clean animal to the clean pen 10 days before farrowing.
- Provide light bedding of chopped straw 2-3 days before farrowing.
- Appearance of milk in teats when pressed indicates the approach of farrowing time.
- Attend the farrowing throughout. It may last up to 24 hours.
- Wipe the piglets clean with towel/straw. Disinfect the naval cord with tincture
of iodine. Normal healthy piglets suckle teats within 10-30 minutes. Help small
piglets to suckle.
- Placenta, dead piglets, soiled bedding etc. may be removed and buried in time with
least delay. The placenta will be expelled generally within a short while.
- Provide 50 mg iron (Imferon 1 ml) on the second day intra-muscularly to prevent
piglet anaemia. Oral administration of iron solution (1 g Ferrous sulphate in 25
ml of water) 1 ml per piglet once a week can be tried. A second injection may be
given at 5 weeks of age.
- Keep the farrowing pen warm, dry and clean.
- Needle teeth may be removed carefully.
The time taken for expulsion of litter vary from 1 hour to 5 hours. The interval
between the birth of the first and that of successive piglets vary from a few minutes
to 3 hours. About 30 per cent of piglets are usually born in posterior presentation.
Generally placenta is shed only after all the piglings are born. Expulsion of placenta
is usually within 3 hours after expulsion of foetus. Piglets start suckling within
10-15 minutes after birth. Artificial heat may be provided by using an infrared
lamp / ordinary electric bulb during cold and rainy season to avoid death due to
chilling.
Growing and finishing
pigs
This period may be considered from weaning (9-10 kg) to the slaughter weight of
90-100 kg. Entire males, castrates and females can be fattened for meat purposes.
The entire males and females may have higher feed conversion efficiency than castrates.
Castration if required may be done at the age of 3-6 weeks. Castrates are more docile
and put on slightly more fat. Growers may be grouped according to sex, size and
weight as uniformly as possible. The difference in weight between the small and
large pig in a lot should not be more than 20%. Up to 15 pigs may be conveniently
put together in a pen. In summer, sprinklers, wallowing tanks etc. may be provided
in addition to shades to cool pigs. Poor growers may be identified, culled and removed
from the lot at the earliest. Deworming may be done two weeks after weaning and
may be repeated once in two months if necessary.
Orphan pigs
When a sow dies or fails to produce milk or does not claim her pigs, the piglings
should be promptly shifted to a foster mother. Some sows may refuse to suckle alien
piglings. Care should be taken to simulate the conditions including the odour and
body size of piglings when admitted to a foster mother or another suckling sow.
If a suckling sow is not available, hand feeding would be necessary. Cow’s
milk is the best substitute for sow’s milk. Buttermilk or sweet skim milk
can also be used. Each pigling may consume 300-500 ml milk per day. Best results
may be secured by feeding 5-6 times a day for the first few weeks and thereafter
the frequency may gradually be reduced to 2-3 times. Any standard vitamin preparation
two or three times the quantity used for infants may be administered to the piglings
until they start taking feed. Injectable iron preparation (e.g. Imferon) may be
given as usual. A 60-Watt electric bulb may provide enough warmth for the piglings
during the early days of life.

Manure disposal
The dry solid dung may be collected morning and evening and stored in the dung shed.
The liquid part of urine and washings may be taken to settling tanks.
Integration
Pigs can be effectively integrated to a biogas plant for meeting the cooking /lighting
demand of the farmers. It can also be integrated to agriculture and fish culture
thereby increasing the overall economic efficiency of the system. The pig dung is
good organic manure in dried form or as compost.
