To be honest meron nang nagpost ng ganitong request dati....
Medyo mahirap po kasi ito. You cannot really say na this antibiotic is for disease etc... Ang proper way to do kasi is to do antibiotic sensitivity testing to know what antibiotic will be effective sa mga microorganism na makikita sa inyong farm.
Personally, ang lagi ko lang sinasabi is start sa lowest na antibiotic like penicillin or tetracycline was na hindi ito effective saka ka lang tataas. At yun susunod na gamot na gagamitin mo is depende naman sa assesstment ng vet mo....
