Kooiker - 4/25/2025 14:05 23 p/s/y farrowing outdoors would be impressive but still a far cry from 30+ of confinement production.
Financially, even with less overhead, there's no way the outdoor production could compete without selling their product for a substantial premium.
Even older paid for confinements have trouble competing (with newer ones) if they don't produce close to the top.
That 23p/s/y was in 1999.

I assume you have the boom/bust pig cycle in the USA too. There's less capital tied up with outdoor pigs |
