We are using this thread as an example for an Internet class.

In that case lesson one is find the right group.

Pigs are rarely discussed here, it's mostly politics of various sorts.

Lesson two is to ask more specifically, general questions tend to be
ignored. Life is too short.

Have you googled groups for south africa and pig farming?
(Not that you are likely to get much).
