Is your pig farm a blue ear seedling, a classic strain or a mutant strain (highly pathogenic)?

Summarize the feedback results of pig friends. This survey is really meaningful, so I have watched it more than a thousand times, but the people who are willing to announce the truth and vote are still single digits, which is really sad. However, this survey is mainly for the benefit of pig farmers, so I still sorted out the situation, hoping to help everyone. In fact, the reaction of several field leaders has been several typical usages. I think it will be very helpful for the field leaders who are considering blue ear vaccine to discuss with their bosses. So, you can continue to look at those who only look at it, hoping to help you; If you see the value of this feedback, I hope you can contribute to the vote and reply to the virus strain and usage. The summary is as follows: CH- 1R Shanghai Lihai sows are generally pig-free @ TJM-F Shaanxi Langke piglets and reserve 10 day old/first pig friend @ Shuda 1 36VR2332+JXA-1day old classic.
