Well, I've been researching the growth of BP's lately, and I came across this:

Feeding should be done on a random basis since all snakes are opportunistic feeders in the wild. The amount and size of prey should vary as well to help to fulfill the snakes' opportunistic feeding habits. Most breeders will recommend regular feedings and specific size prey animals, but remember their goals are to raise and animal fast so that it reaches sexual maturity in a hurry, not to provide the best possible captive long-term environment. There is nothing wrong with this method either it is just geared toward rapid growth for the purposes of breeding since a snake's growth is related to the amount it eats. The only problem with a constant set diet appears to be that it shortens the over all life span of the animal. Random feeders seem to live longer according to most veterinary studies.
