UK sow numbers have already been hit by a 15% increase in slaughtering of sows in the first three months of 2011, although this had been expected after more gilts were added as breeding herd candidates in 2010. The debate among observers is whether extra productivity will allow pork supplies to be maintained, even with a projected decline in the population of sows in 2011.
The average producer of finishing pigs in Britain at present is losing around UK£18 (US$29.96) per pig sent to market, despite a slight easing of production costs during March and April 2011 to around UK£1.60 (US$2.66) per kilogram carcass weight. This follows annual averages of -UK£11 (US$-18.31) per pig in 2007 and -UK£8 (US$13.31) per pig in 2008, although there was a short-lived recovery to a profit of UK£11 (US$18.31) per pig in 2009 before negative margins returned with higher feed costs towards the end of 2010.
Calculations by the British Pig Executive showed losses averaging UK£22 (US$36.61) per pig in January 2011, rising to UK£25 (US$41.61) in February and UK£26 (US$43.27) in March before easing slightly to an estimated UK£19 (US$31.62) in April and UK£18 (US$29.96) in May.
