Roman military diet - bone database

[Caratacus]

You might try looking up the excavation report on Segontium by Casey & Davies (CBA Research Report 90). If memory serves, there is a section there on the bone finds. One of the things that they found was that there was a change over time (the site was occupied for around 300 years), with a switch to cattle, rather than pigs and mutton and also that the animals got bigger, suggesting that local farmers who supplied the military were breeding bigger beasts to order.
