But there are some--even among intelligent farmers--who make a practice of turning their calves out to pasture at the tender age of two or three weeks--and that, too, when they have sucked the cow up to that time--and allow them nothing in the shape of milk and tender care. This, certainly, is the poorest possible economy, to say nothing of the manifest cruelty of such treatment. The growth of the calf is checked, and the system receives a shock from so sudden a change, from which it cannot soon recover. The careful Dutch breeders bring the calves either skimmed milk or buttermilk to drink several times a day after they are turned to grass, which is not till the age of ten or twelve weeks; and, if the weather is chilly, the milk is warmed for them. They put a trough generally under a covering, to which the calves may come and drink at regular times. Thus, they are kept tame and docile. In the raising of calves, through all stages of their growth, great care should be taken neither to starve nor to over-feed. A calf should never be surfeited, and never be fed so highly that it cannot be fed more highly as it advances. The most important part is to keep it growing thriftily without getting too fat, if it is to be raised for the dairy. The calves in the dairy districts of Scotland are fed on the milk, with seldom any admixture; and they are not permitted to suck their dams, but are taught to drink milk by the hand from a dish. They are generally fed on milk only for the first four, five, or six weeks, and are then allowed from two to two and a half quarts of new milk each meal, twice in the twenty-four hours. Some never give them any other food when young except milk, lessening the quantity when the calf begins to eat grass or other food, which it generally does when about five weeks old, if grass can be had; and withdrawing it entirely about the seventh or eighth week of the calf's age. But, if the calf is reared in winter, or early in spring, before the grass rises, it must be supplied with at least some milk until it is eight or nine weeks old, as a calf will not so soon learn to eat hay or straw, nor fare so well on them alone as it will on pasture. Some feed their calves reared for stock partly with meal mixed in the milk after the third or fourth week. Others introduce gradually some new whey into the milk, first mixed with meal; and, when the calf gets older, they withdraw the milk, and feed it on whey and porridge. Hay-tea, juices of peas and beans, or pea or bean-straw, linseed beaten into powder, treacle, etc., have all been sometimes used to advantage in feeding calves; but milk, when it can be spared, is, in the judgment of the Scotch breeders, by far their most natural food.
