British farmers have been pushing for such a deal for some time, aware that China’s growing appetite for pork has not been matched by a similar increase in the efficiency of their farming methods.
Using better semen to breed pig stocks is one of the key ways Chinese farmers want to use to improve their yields without wreaking huge environmental damage.
Pork barrel politics: U.K. pig semen heading to China

Actually, the number of boars required for a large hog herd is not all that large. When I was growing up our family had a 4000 head hog ranch. We bred the ol' fashioned way, and I doubt we had more than 30 boars and around 400 sows and gilts (a female breeding pig that hasn't had her first litter yet). Each boar can be expected to bred at least one sow a day, usually servicing it twice. Since each litter is around 10 or 12 pigs, it doesn't take a lot of breeding stock.
Even here in the US a lot of hog farms use artificial insemination. In the high-production environment of most modern hog farms it usually pays to use semen from superior boars, and boars produce much more semen than is needed to conceive a litter.
BTW: China now got approval to buy Smithfield, the largest US PORK Company...
China is bringing home the bacon...
