The UK has made an agreement with China to export £45 million worth of pig semen during David Cameron's trade visit to the country.
A Downing Street spokesperson said: "We're doing all we can to ensure that businesses up and down the country reap the rewards from our relationship with China. And that includes our pig farmers.
"This new deal to export pig semen will be worth £45 million to UK firms and means Britain's best pigs will help sustain the largest pig population in the world.
"And we're not stopping there, we're talking to the Chinese about serving up pigs trotters on Beijing's finest dining tables. That would be a real win-win - a multi-million pound boost for Britain and a gastronomic treat for Chinese diners.”
The semen exports are expected to begin in 2014.
