I know terms for the meat of young animals of a specific species, such as "lamb" (also the name of a young sheep) and "veal", and the meat of old animals of a specific species or set of closely related species, such as mutton. But are there any terms for the meat of young animals in general, terms for the meat of old animals in general, and for those in between?
For the example of how it'd be used, as mandated in the tag wiki for single word requests: I'm currently using
Do [the aliens] want human lamb, human hogget, or human mutton?
which is probably likely to be understood, but I'd like to know if there's more accurate words to use in this context. I assume the English language doesn't have words specifically for the meat of young humans, medium aged humans or old humans, so the most accurate approach would be saying "human [generic term for young animal meat]", "human [generic term for medium aged animal meat]", and "human [generic term for old animal meat]".
