Its interesting that the cost of the slurry store and the value of the
cows and youngstock in the herd are almost precisely the same.

The store, though, is a constant cost (management and emptying) and

It really doesn't surprise me that pig production is being exported to

exporting. Just the thing that ecofreaks get very upset about for
industrial waste import/export.

We are aware of this too.
