With respect to outdoor pig stocking rates, most of us are short term tenants on arable farms. Therefore high rents are the norm. In my neck of the woods we have to compete with high rent paying alternatives such as root vegetables and now AD maize, so rents of at least £300 per acre are the norm, so driving an economically sustainable stocking rate of about ten sows per acre. It would be normal to move sites every two years.
Of course if it was my own place I would do it very differently.
On labour, I would be fairly typical, with 1000 sows, selling piglets at weaning, employing two and working hard myself, so one per at least 300 sows, thanks to nut throwing machines.
Having had a bit to do with NPA, I would be very careful about engaging too much with Philip Lymbery.
£300!!!! Don't know what to say apart from you will be running a very efficient ship.
labour---we ran 1 man to 100 sows but that was finishing everything which I imagine is not too far off your 3 to 1000 sows selling weaners?
The main difference in our systems then would be that we had more forgiving land, we had an inputted rent half the rate you are paying and we moved pigs on rapidly----typically every 6 months
