I read a scientific paper many years ago about this very subject. It was a study on a species of python, which fed almost exclusively on rats. During the years when the rat populations were high, the pythons growth rate was very high and they reached the size of a 3-4 year old python in just 1 to 1 1/2 years. Wild pythons, and I am sure boas, are very opportunistic and will take a pray animal when the opportunity presents itself. This means that in the wild they will “Power feed” themselves if given the chance.
Wild conditions and captive conditions are very different. Wild snakes get much more exercise than captive snakes, which we raise as couch potatoes. We can’t teach them to crawl on a tread mill now can we. Wild food items get more exercise as well and are not big fat rats like we feed in captivity. If the cage enclosure is big enough and the proper temperature gradient is provided, I do not see any problem with growing a boa up rapidly. I agree that larger food items spread out a little more is better, but if they will take the food, it is probably not a bad thing when they are young and growing.
Adults can get very fat! Breeding females will need a lot more food than males. Once boas are grown many factors will decide how much food they will need. Their food intake will need to be adjusted to their conditions on an individual case by case basis. This is where a little experience comes in. It is unlikely that female boas breed every year in the wild, but in captivity, this may be our goal. In this case, the females will need to be “Power fed” if there is any chance for them to breed more often than they would in the wild.
It is unlikely that we will ever duplicate the conditions in the wild, and we may not want to either. Do we want to wait 5-6 years for a female to start breeding, or do we want everything to be accelerated. In the wild, if the food is available, females may reach breeding size in 2 - 3 years, so there is no real right answer to the Power feeding question. There will always be two sides to this issue, and I guess it is up to each of us to decide which course they want to take. I breed a lot of different kinds of snakes and my females get just about all the food they want. If they don’t they may not reproduce and most breeders goals in a captive breeding programs is to produce offspring.
Everything can obviously be over done, so perhaps we can use a little control if we choose to “Power feed”. I have started to get on a schedule of feeding young snakes and females about every 5 days as much as they want, which works for me under my conditions.
