Problem: Text: 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.

Problem: Text: Of the 71 words in this list, 67 are nouns, and most would generally be considered loanwords; the only modern-English words that contain Q not followed by U and are not borrowed from another language are qiana, qwerty, and tranq.

For words to appear here, they must appear in their own entry in a dictionary; words which occur only as part of a longer phrase are not included.
