If the farmer wanted organic weaners does that mean you would have to have fed your sow organically as well as technically the milk she has beed feeding them would not be 100% and the food you have fed them up to leaving your property should also be organic?
The two I've sold are going to an organic farm, but will not be reared organically.
In this case it's the other way about. The weaners will be reared for the household, and they are not bothered about them being organic. They have placed no restrictions on me whatsoever, having checked with their certification body that it is ok for them to buy non-organic pigs and rear them non-organically on the organic land. Obviously they could not sell the pigs nor the pork as organic - but they don't want to, so that's fine.
It is me that is wanting to be a bit careful about the wormer (if any.) I know that some of the chemicals we put down the throats and into the bloodstream and flesh, and on the skins, of our livestock continue to have effects beyond the intended ones on the parasites or other conditions on or in the livestock. For instance, a farm which puts Clic on its sheep is likely to find the cow pats lying, not getting broken down and incorporated into the soil, as the active ingredient in the Clic survives its passage through the sheep and kills dung beetles amongst other soil organisms for many weeks or even months.
