As alreadypreviously said & ouch 
A hard lesson learned, done it myself in the past too     I think many of us have been caught-out by unscupulous "breeders" of various species     Difficult to know who it is we're dealing with sometimes - they may have appealling adverts & professional looking websites, but there's nothing like recommendations from folks on here & of course going with gut instinct.
At least you will be able to give them a happy life now.

Piglets went back last night.  Two wouldn't even lap and I was feeding with a syringe.     I spoke to the guy who still swore they were 8 weeks old but said he'd put them back on the sow.  I took them back and handed them over the gate.  Place has more security than a military base.

Before I took them back I weighed them... they were all between 4 and 5 1/4 kilo's......

I would ring Animal Health  on welfare grounds.

Inclined to agree with eastling. This guy wants reporting that is certainly not weights of 8 week weaners. A 2-3 week Berkshire would weigh that.

[Beewyched]

Even a KK piglet should weigh more than that at 8 weeks 
Putting them back with the sow     If they were properly weaned then mum wouldn't still be producing milk surely    no wonder he won't let you see his set-up 
I agree with Eastling & BB - get AH in, there's definately something dodgy going on there - whether it's "piglet farming" or honest ignorance, his animals are suffering because of it

This sounds so much like 'puppy farming' practises - nothing is sacred or safe from such people is it?

Please report this person to the relevant authorites (not the RSPCA they're useless) as soon as possible. I would have to as i wouldn't be able to sleep at night knowing i'd sent back those piglets to such miserable conditions.

You can report him  anonymously  to Animal Health if it helps. Agree with Mandy re RSPCA not worth the phone call.
