A shelter is also of some importance as a windbreak. Moving air abstracts heat from the body much more rapidly than still air of the same temperature and humidity. (4) Water-supply.—A sufficient water-supply is important for all classes of animals. With our domestic animals the normal consumption is three to four times that of the dry matter of the food. When practicable, the water-supply should be always accessible. The temperature of the water for fat- tening animals is probably rather unimportant, since, as has been seen, such animals are usually producing an excess of heat. It is not impossible, however, that the drinking at one time of much very cold water may temporarily require an increased production of heat to warm it promptly to the temperature of the body. For this reason, as well as in order to give opportunity to the animals to consume all the water needed, a water-supply accessible at all times is very desirable. Milk production. Since but little milk is produced in the United States except by cows, the following discussion will be confined to the feeding of these animals. Milk production differs very essentially from meat production. In the latter we desire to secure an increase in the size and weight of the animal, and, broadly speaking, all the food supplied in excess of the maintenance requirement aids in producing the desired result. In milk production, on the contrary, what we desire is the product of a single gland of the body. An increase in the weight of the mature animal is not desired; it is at best a diversion of the food to a use other than that intended, while
