SWINE BITING PREVENTION
Pigs are intelligent animals and get bored easily unless they are kept busy.  They may have a tendency to bite the tails of each other.  Put toys in the pen for them to play with.  Give them things that they can push around and get rough with.  Old tires are good play things for them.

PIGS
Plant Varaghu (Kudo Millet – Arka millet) all around as fence to prevent pigs.  They hate the smell.

WORMING SWINE
Leave small lumps of coal in the pen.  They will eat what they need to keep worm free.
