The total number of pigs remained almost unchanged in 2011 at 4.4 million. Despite increased feeding costs, there was virtually no change seen in the number of fattening pigs which remained at 3.9 million. The number of breeding pigs increased by 1.0 per cent and now stands at 523 thousand.
On the other hand, in 2011, compared with 2010, the value of production at market prices for pigmeat rose by 10 per cent to £1.1 billion.
