Thank you so much everyone, all of your kind words are really helping me to get through this horrible time. I'm sorry it's took so long to get back to everyone, we've had an awful 24 hours in which we have lost another 5 pigs, leaving us with 6 out of our original 16
2 of the deceased pigs have gone for postmortem and the 6 pigs that are still here have all been seen by the vet.
The vet found that 2 out of the 6 remaining have base? crackles in their chest and sound congested although not showing obvious outward signs yet. All 6 have been put on a ten day course of Zithromax as the vet suspects something viral such as pneumonia. The pigs with the noisy chests have been given furosemide onlinside their antibiotics as well to help with the congestion.
We've completely stripped the their setups and f10'd everything we can just to get rid of any bugs on the setup and they've gone back on fleece just in case the new rapeseed straw bedding was carrying anything.
For now we just hope that the antibiotics will help the remaining pigs. We are on lock down for at least 4 weeks anyway, no pigs in or out, regular f10'ing of their setups too. They are going back to the vets at the end of their course for another checkup.
I'm just completely lost, my poor poor pigs
