The Government will also place restrictions on the time pregnant sows are allowed to be kept in stalls - three years before the planned introduction of new national animal welfare regulations.
Mr Green said the bans would be phased in to allow pig producers time to adjust to the changes.
The restrictions on pregnant sows will take effect from 2014 and the routine use of dry sow stalls will be banned from 2017.
