I have feed both frozen and live, currently feeding all my BP's live due to convenience. I have not fed enough F/T to notice a difference in the growth rate in live vs. frozen. My thoughts on frozen is that there is some nutritional breakdown in the "meat" during freezing process though I do not think it is significant enough to effect the growth rate in your snake. However what I believe that along with killing bad bacteria in the freezing process it also kills any good fauna in the feeder that would otherwise be past on to the snake if it had been alive, which would benifit the snake with digestion and obsorbtion of nutrients and such and so forth. just a thought.

My second thought is the nutrition the feeders nutrition from the petshop you go to for live and what the frozen place feeds them. perhaps the dog food they are feeding or they are feeding something else that is otherwise giving them some kind of nutritional boost, or maybe they just hit a growth spurt?.

Hmmmm, I smell an experiment coming for my next clutch now that I have an empty freezer in the garage.
