The 11 girls, who are all members of Young Farmers' Clubs (YFC) in North Devon, stripped off for the 2010 Cancer Research UK calendar.
They are hoping to raise £2,000 in sales from the calendar and are pictured doing farmyard chores - from milking cows and dressing horses to firing shotguns.

The project was the brainchild of 18-year-old YFC member Hayley Cooper. She said: 'I try and do something for charity every year but this has been by far the most nerve-racking.
'When I first had the idea and rang around the YFCs to see who was interested, loads of girls signed up but said they never thought it would actually happen.
'When I rang them all back a few months later to say that I had booked the photographer, they were all very surprised and worried - a few even made their excuses and dropped out.'

The shoot took place last month at Miss Cooper's farm in Roborough.
Georgie Harris, who appears in the calendar as Miss June, said: 'The day of the shoot was most amusing - especially when the local churchgoers of Roborough turned up for a service and got a good eyeful of me posing for my photo - how embarrassing.'
Jenny Ashton, who is Miss September, said: 'I was slightly nervous but after the first photo I was well up for it.
'The only down side of the day was being pooed on by the cow I was standing with - it was extremely funny but I had to be cleaned off while standing naked in a parlour.'

Miss Cooper added: 'Both my granddads and my auntie died of cancer so my main motivation for doing this calendar is for them.
'We hope to raise more than £2,000 from sales of the calendar, all of which will go to Cancer Research UK.'
A local farmer commented: 'They are all pretty girls and this will probably see a big rise in people wanting to join the YFCs.
'They are all starkers apart from their colourful wellies. I wouldn't mind them in my fields,' he said.
