I have used PPDB before from a different manufacturer but this new one comes in IU/mL, not in mg or ug, so I don't know how much to use.
Bovine PPD is usually 1mg/ml while avian PPD often used is 0.5mg/ml. This is for the potency. Could u tell us the exact IU/ml so we might help you with the estimations of the right dose and the concentrations.
Thanks so much for your answer! I have used it already
