The word cattle has no singular form, as the male bull and the female cow have markedly different temperaments. However, cattle are often referred to as "cows", whether male or female. The offspring of cattle is a calf (plural calves).
A castrated bull is called a bullock.
During his sojourn in Haran, Jacob prospered while tending cattle for Laban. (Gen. 30:40)
The female appears placid and contented and can be easily approached and milked, even by a child. The bull is considered dangerous and is typically penned up far away from any cows.
There are over 60 breeds of cattle worldwide, including the Brahmin, Zebu, and Hereford.
Uniformitarian thinkers claim cattle were domesticated by mankind over thousands of years  but Christian believers prefer to argue that these creatures were created by God as they are today for the benefit of mankind.
