Yes. Mainly because the captive raised animals have not learned the same behaviors as the wild ones. If an animal does not have to forage, but is simply handed a meal, then it doesn't know how to find a meal. If it has never faced predation, it does not know how to escape. Lots of data on these ideas in the literature.
