Figures published by Defra on agriculture in the English regions for 2012 show that output from pigs was up nearly 8% on the previous year at £940 million. The increase was due both to increased slaughterings and higher prices.
Pigs accounted for just over 5% of gross agricultural output in England during the year and 20% of output from farming for meat production.
About 60% of English pig output was from just two regions, the East of England and Yorkshire and the Humber. Pigs accounted for about an eighth of agricultural output in the latter but only 2% in the North-west.
