The relationship between landowners and tenant farmers can be a difficult one - but it’s hoped a new Code of Practice could help improve things. It was one of the key recommendations of the Rock Review into tenant farming in England. The Tenant Farmers Association has called it a “major step forward”, saying “for too long tenants have felt marginalised and mistreated.”

And we visit a state of the art pig farm to find out about a replacement for ‘farrowing crates’. These are the small pens where sows are confined by rails while, and after, giving birth to stop them lying on and smothering their piglets. Sows can get up and lie down, but not turn around or move about until the piglets are weaned when they’re about a month old. The use of these crates is banned in Sweden, Norway and Switzerland and they may also be phased out in the UK.
