“The common yield is from fifteen to twenty tons (of green feed) per acre. About the first of August, when heat and flies are too oppressive for cows to feed quietly in the day-time, I commence feeding them with what corn they will eat in the morning, daily, which is cut up with a grass-scythe, and drawn on a sled or wagon to the milk-barn and fed to them in the stalls, which is one hour’s work for a man at each feeding. When thus plentifully fed, my cows have their _knitting_-work on hand for the day, which they can do up by lying quietly under artificial shades, erected in such places as need manuring most, and are most airy, by setting posts and putting poles and bushes on top, the sides being left open. These shades may be made and removed annually, to enrich other portions of soil, if desired, at the small expense of one dollar for each ten cows. At evening, my cows are fed whey only, because they can feed more quietly, with less rambling, and will give more milk by feeding most when the dew is on the grass. “The capacity of cows for giving milk is varied much by habit. In fall, after the season of feeding is past, I feed four quarts of wheat bran or shorts made into slop with whey, or a peck of roots to each cow, till milking season closes (about the first of December). When confined in stables and fed hay and milked, they are fed each one pail full of thin slop at morning before foddering, and also at evening, to render their food more succulent, and they will not drink so much cold water when let out in the middle of the day. In cold weather cows are kept well attended in warm stables. No foddering is done on the ground. Thus a supply of milk is kept up, and the cows get in good flesh, while their blood and bags are left in a healthy condition when dried off. “This flesh they hold till milk season in spring, without other feed than good hay. They will not get fleshy bags, but come into milk at once. About the first of April they are carded daily, till they are turned to grass. Wheat-bran in milk or whey, slops, or roots, are daily fed, as they are found best adapted to the nature of different cows, and most likely to establish a regular flow of milk till grass comes.” All practical dairymen concur in saying that a _warm and well-ventilated barn_ is indispensable to the promotion of the highest yield of milk in winter; and most agree that cows in milk should not be turned out even to drink in cold weather, all exposure to cold tending to lessen the yield of milk.
