They are just a species of cockroach that are easy to keep/breed and are a great food item for many lizards. Herpshop has a care sheet on keeping/breeding these roaches on their website that you may find informative.
Anyway to answer your question,
Feeding large quantities to maintain constant food supply while you are away would not be the best idea for several reasons.
1. You dont want them to over feed.
2. You should keep an eye on them while feeding to avoid rival competition, fighting over food etc.
3. You could come home to find that many roaches have hidden in cracks and crevices within the enclosure, perhaps even laying eggs.
I think the best thing to do would be have a close friend or family member (preferably somebody with knowledge of herps) over to feed them if you were to go on a holiday. This would be a much wiser proceedure because not only will they be fed adequately, but they could be watched and examined for many signs while you are away. This will make your return home much more easier concerning your herps if you have a herp sitter that can easily identify and describe any ill healths, non feeders, breeding behaviours etc.
