Thanks, doc.
Upon further reading sa mga sites, it may seem to be pseudorabies po tumama sa kanila. To understand it, I have to go back to the time na nagkaprob and found that there is a common figure/item, the pig's pens which are near my boar. For all instances kc po, doon lagi na nkttang may natatamaan with those signs, including sneezing, parang may uhog sa ilong then incoordination including ung head kumikiling sa isang side.
I have two boars kasi which their pens have been part of the growing pen, nilagyan lng po namin ng divider, steel bars lng po pagitan. For some reason po cguro, the weaners na nailagay namin doon sa adjacent may have direct contact to the boar's nose, etc. That the boar may already be a carrier of herpes virus which triggers that disease spreading and its symptoms na parang pneumonia ung result.
It's a lessons learned and I have immediately transferred my boars to a renovated pen instead and have then vaccinated all of my weaners to prevent further outbreak.
Per latest news ng tao ko po (as I'm based in Manila), no other similar diseases is seen in the herd.
I hope I made the right move. =)
