To maintain lactation, a dairy cow must be bred and produce calves. Depending on market conditions, the cow may be bred with a ''dairy bull'' or a ''beef bull.'' Female calves (heifers) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef. Male calves can either be used later as a breeding bull or sold and used for veal or beef. Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. A cow's gestation period is approximately nine months. Newborn calves are removed from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow and calf.

do dairy cows have to be pregnant to produce milk?

A: yes

At the time of the decision about building the tunnel, 15.9 million passengers were predicted for Eurostar trains in the opening year. In 1995, the first full year, actual numbers were a little over 2.9 million, growing to 7.1 million in 2000, then dropping to 6.3 million in 2003. Eurostar was initially limited by the lack of a high-speed connection on the British side. After the completion of High Speed 1 in two stages in 2003 and 2007, traffic increased. In 2008, Eurostar carried 9,113,371 passengers, a 10% increase over the previous year, despite traffic limitations due to the 2008 Channel Tunnel fire. Eurostar passenger numbers continued to increase, reaching 10,397,894 in 2014.
