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.

For example, if a player has only the 7 of diamonds and 8 of diamonds left in their hand, and they draw the 9 of diamonds (forming a sequence), then whether they win the hand or not depends on if they are playing the discard rule variation. If they are playing this variation, they can not win the hand at this point, because they have to finish the turn by discarding one of the three cards in their hand, causing them to no longer have a sequence. However, if the player is allowed to lay off this sequence without a final discard, then the game ends when the player lays down the sequence. And a player can lay down cards afterwards. A player may not win or go out if rummy is declared on the board. You may also pick up from the discard pile and discard that card only if it is with another card.

Romaine or cos lettuce (Lactuca sativa L. var. longifolia) is a variety of lettuce that grows in a tall head of sturdy dark green leaves with firm ribs down their centers.

In North America, romaine is sold as whole heads or as ''hearts'' that have had the outer leaves removed and are often packaged together.
