Upon the conclusion of the fourth season of the series that December, Conrad wished to leave the series to pursue other career opportunities. However, per the producers' requests, she filmed ten episodes for the following season, in which she closed her storylines. Conrad made her final appearance on the series in May 2009, attending Montag and Pratt's wedding after much deliberation during the mid-season finale of the fifth season. However, in the July 2009 issue of Cosmopolitan, she stated that producers had pressured her into a reconciliation with Montag throughout the season, adding that she was displeased when they would not allow otherwise. Conrad was replaced by former Laguna Beach castmate Kristin Cavallari until the series' conclusion in July 2010.

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.
