What do you call a newly born cattle?

A newly born cattle is referred to as a calf. This term specifically denotes a very young bovine animal, typically under one year old. The classification of cattle into various categories such as heifer, bull calf, and steer further defines their age, sex, and purpose but does not alter the fact that any newborn is classified as a calf.

Heifer refers to a young female that has not yet borne a calf, while bull calf is a term used for a male calf, and steer describes a male that has been castrated. Thus, while each alternate option serves a specific purpose in cattle classification, "calf" accurately captures the general designation for all newborn cattle.
