Preparing for birth
Most dairy farms don't keep bulls anymore, and dairy cows are bred using artificial insemination. If this is to be her first calf, the cow will stop milking for a two-month dry period before insemination. A cow's gestation period (time from conception to birth) is typically about 276 days, 10 days longer than humans.
Did you know?
A young cow who hasn't given birth yet is called a heifer. Heifers are usually bred at about 15 months of age and can't produce milk until they've given birth to a calf. They'll produce milk for about 10 months afterward.
