It appears from these, and other similar instances of successful soiling, or stall-feeding in summer on green crops cut for the purpose, that the largely increased quantity of the yield fully counterbalances the slightly deteriorated quality. And not only is the quantity yielded by each cow increased, but the same extent of land, under good culture, will carry double or treble the number of ordinary pastures, and keep them in better condition. There is also a saving of manure. But with us the economy of soiling is the exception, and not the rule. In adopting this system of feeding, regularity is required as much as in any other, and a proper variety of food. A succession of green crops should be provided, as near as convenient to the stable. The first will naturally be winter rye, in the Northern States, as that shoots up with great luxuriance. Winter rape would probably be an exceedingly valuable addition to the plants usually cultivated for soiling in this country, in sections where it withstands the severity of the winter. Cabbages kept in the cellar, or pit, and transplanted early, will also come in here to advantage, and clover will very soon follow them; oats, millet, and green Indian-corn, as the season advances; and, a little later still, perhaps, the Chinese sugar-cane, which should not be cut till headed out. These plants, in addition to other cultivated grasses, will furnish an unfailing succession of succulent and tender fodder; while the addition of a little Indian, linseed, or cotton-seed meal will be found economical. In the vicinity of large towns and cities, where the object is too often to feed for the largest quantity, without reference to quality, an article known as distillers’ swill, or still-slop, is extensively used. This, if properly fed in limited quantities, in combination with other and more bulky food, may be a valuable article for the dairyman; but, if given, as it too often is, without the addition of other kinds of food, it soon affects the health and constitution of the animals fed on it. This swill contains a considerable quantity of water, some nitrogenous compounds, and some inorganic matter, in the shape of phosphates and alkaline salts found in the different kinds of grain of which it is made up, as Indian corn, wheat, barley, rye, &c. Where this forms the principal food of milch cows, the milk is of a very poor quality--blue in color, and requiring the addition of coloring substances to make it salable. It contains, often, less than one per cent. of butter, and seldom over one and three tenths or one and a half per cent., while good, salable milk ought to contain from three to five per cent. It will not coagulate, it is said, in less than five or six hours, while good milk will invariably coagulate in one hour or less, under the same conditions. Its effect on the system of young children is therefore very destructive, causing diseases of various kinds, and, if continued, certain death.
