09 Follow-up check on the farm’s clinical picture.

[A week later] You haven’t heard from Charlie yet, so you have no idea how the pigs are doing.  You dial him up while scanning over the diagnostic lab report.  Charlie answers and you ask how things turned out.  “Well, I injected ‘em all and ran that stuff in the water.  They stopped dying withintwo days , but Doc they look rough.  I still see a little scouring and the cough is gone, but man they look rough.  Like they’re stunted.” 

You pause to consider what he’s said.  Yes, this has played out like a very typical F18 outbreak.  Rapid onset, high mortality, and then large numbers of crummy-looking pigs that take a long time to recover.  “The lab found F18 and that fits with what you’re describing, Charlie.  The drugs you used were a good choice, but it can take a while to recover from the damage from an outbreak like this.  Those rough pigs won’t snap back immediately.  How’s the West barn?”

“Oh, they look great.  I guess it’s just a problem with the East barn, huh?” 

You know that the West barn had dodged a bullet.  Maybe it was a contaminated trailer that happened to haul pigs to the East barn.  Maybe it came with the pigs from the sow farm, and there was enough pathogen-load in the East barn pigs to ramp up the problem.  Maybe the pigs were stressed…was the East barn’s feed mixed correctly or maybe the pigs were all chilled and  loaded into a damp barn.  There are a lot of questions, but you know that wishful thinking will not keep the West barn safe.  You and Charlie need to do some preventive planning.
