steer or ox
Beef from cattle slaughtered up to four and a half years old is called manzo.
Castrated cattle, or steer, are bue, and can be slaughtered after four and a half years, although now that few are used as work animals, they are usually butchered earlier for the table.
The Bue Rosso (also known as the Sardo Modicana) is a rustic breed of red cattle that in Sardinia graze free range on wild myrtle, juniper, camomile and asphodel, lending a distinctive herbal flavour to the milk and meat.
The Italian expression 'Il bue che dice cornuto all'asino' (The ox that says the donkey has horns) is similar to the English 'the pot calling the kettle black'.
