"From these experiments, it appears that the least quantity of food, which is required for fattening, is when animals are kept closely confined in warm shelters; and the greatest quantity when running at large, exposed to all weather. But, although animals will fatten faster for a certain time without exercise than with it, if they are closely confined for any considerable time, and are at the same time full fed, they become, in some measure, feverish; the proportion of fat becomes too large, and the meat is not so palatable and healthy as when they are allowed moderate exercise, in yards or small fields. "As to the kinds of food which may be used most advantageously in fattening, this will generally depend upon what is raised upon the farm, it being preferable, in most cases, to use the produce of the farm. Sheep prefer beans to almost any other grain; but neither beans nor peas are so fattening as some other grains, and are used most advantageously along with them. Beans, peas, oats, barley, rye, buckwheat, &c., may be used along with Indian corn, or oil cake, or succulent food, making various changes and mixtures, in order to furnish the variety of food which is so much relished by the sheep, and which should ever be attended to by the sheep fattener. This will prevent their being cloyed, and will hasten the fattening process. A variety of food, says Mr. Spooner, operates like cookery in the human subject, enabling more sustenance to be taken. "The quantity of grain or succulent food, which it will be proper to feed, will depend upon the size, age, and condition of the sheep; and judgment must be used in ascertaining how much they can bear. Mr. Childers states that sheep (New Leicester) fed with the addition of half a pint of barley per sheep, per day, half a pound of linseed oil cake, with hay, and a constant supply of salt, became ready for the butcher in ten weeks; the gain of flesh and tallow, thirty-three pounds to forty pounds per head. (One sheep gained fifty-five pounds in twelve weeks.) "This experiment shows what is about the largest amount of grain which it is necessary or proper to feed to New Leicester sheep, at any time while fattening. The average weight of forty New Leicester wethers, before fattening, was found by Mr. Childers to be one hundred and twenty-eight pounds each. By weighing an average lot of any other kind of sheep, which are to be fattened, and by reference to the table of comparative nutriment of the different kinds of food, a calculation may be readily made, as to the largest amount, which will be necessary for them, of any article of food whatever. "When sheep are first put up for fattening, they should be sorted, when convenient, so as to put those of the same age, size, and condition, each by themselves, so that each may have a fair chance to obtain its proportion of food, and may be fed the proper length of time.
