Gangrenous dermatitis (GD). Even if you can’t pronounce it or spell it, it’s not hard to figure out that it is not something you want on your farm. So, what is it? The short story is that it is a serious bacterial infection that is becoming more and more common as integrators move away from using antibiotics. It is fast acting and targets 4 week to 8 week old birds. It typically starts with a skin wound or a live bird pecking at a dead bird that has the bacteria.
