PRODUCTS OF ANIMALS
Animals are very useful to humans. Students are familiar with their pets, and that meat, milk, cheese, eggs, honey and some other animals products are used as food, but they many not have thought about other uses. Most have never seen a horse or ox drawn wagons and plows but they probably know about horse racing and riding for fun. Some cowboys still use horses, as do some park rangers and police. They many not have thought about leather, violin bows (made with horsehair) and strings (some made with sheep gut), silk, wool, alligator shoes and purses, snake skin hat bands, fur coats, pearls, glue and gelatin (made from cartilage and bones) fertilizer, or truffle-hunting pigs or the cormorants that some Chinese use for fishing.When dairy animals can no longer produce milk, they are often used for meat, primarily in the form of ground beef. It is possible to get the same cuts of meat from a dairy cow that you do a beef animal. Male dairy calves, called bull calves, that are not used for beef are often used for veal. Veal is meat from younger animals and is very lean. It is considered a delicacy in many countries.
