... each sow capable of delivering eight piglets every six to eight weeks.

As someone who knows something about pigs, I'm astonished when I read things in newspapers like:

The pigs reproduce too fast, with each sow capable of delivering eight piglets every six to eight weeks.

That's roughly 59 pigs per sow per year. Please give me some of these magical pigs!

Here's stats on commercial pigs - which have been optimized for production and surviving in an easy environment. 24.6 psy is considered good. A lot aspire to 30 psy (and do everything they can to reach it). 59 psy is ridiculous.
