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.

Some cookware or packaging is marked with symbols to indicate compatibility with induction, gas, or electric heat. Induction cooking surfaces work well with any pans with a high ferrous metal content at the base. Cast iron pans and any black metal or iron pans will work on an induction cooking surface. Stainless steel pans will work on an induction cooking surface if the base of the pan is a magnetic grade of stainless steel. If a magnet sticks well to the sole of the pan, it will work on an induction cooking surface. An ``all-metal'' cooker will work with non-ferrous cookware, but available models are limited.

He spends his life trying to repress evil urges that are not fitting for a man of his stature. He develops a serum in an attempt to mask this hidden evil. However, in doing so, Jekyll transforms into Hyde, a hideous creature without compassion or remorse. Jekyll has a friendly personality, but as Hyde, he becomes mysterious and violent.
