No sir, years ago when I was dealing with constant yearly virus deaths , I was stuck on the use of draxxin for reasons it was the hot drug on the Market , but was advised by one of the Vets, at OSU, that Batril and sulmet r more effective for this form of bacterial pneumonia so what I started doing was if a animal appeared to make it ,I would medicate drinking water with liquid sulmet first 3 to 5 days Then follow up with Batril few weeks later , but please. Understand what I feel has worked for my farms over the years at this time of year not everyone will agree with and I do respect that !
