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!
One Deep AI (or IUI) was performed with frozen semen in China (Wens group): 10 mini straws were thawed at 37°C for 30 seconds in a water bath prior to be mixed in an “all in one “ golden bag.
The sow is now pregnant. The customer is happy and will let us know the number of piglets after farrowing.
