The Dairy Cow as a Producer op Human Food As the price of land, labor, and feed increases, the dairy cow will more and more displace the strictly meat producing animals, for she produces human food far more economically than does the steer, sheep, or pig. That this change is already taking place is brought out by recent cen- sus statistics. These show that between 1900 to 1910 the num- ber of dairy cows in the United States increased about 20 per ct., while the number of other cattle decreased.

This is over 6 times as much human food as is produced by a steer from the same amount of feed. (See Chapter VI.) A dairy cow producing 1 lb. of butter fat per day uses about 47 per ct. of her food for the support of her body, 24 per ct. in the work of converting food nutrients into milk, and actually yields in her milk about 29 per ct. of the digestible nutrients in her This shows her to be a more efficient machine than either the horse or the steam engine. (See Chapter VI.) Dairy vs. beef type.—When in full flow of milk, a high-producing dairy cow is generally spare and shows an angular, wedge-shaped form, a roomy barrel, spacious hindquarters, and a large udder. This conformation is in strong contrast to that of t
