Indeed, the number one of Chinese farms, Wenshi with 270.000 sows, is now using IMV swine frozen semen technologies in order to better control the quality of semen doses.
Using fresh semen doses is hard in China. Semen quality is not guaranty if doses are used more than 2-3 days after collection and after more than a 50 kilometers distance from collection site, because of temperature variation and transportation conditions (big stress impact on semen). With frozen semen, Wenshi is now able to provide doses of quality with a much longer expiry date all around China!
