It may also be well to remember that where rainfall is usually plentiful and sometimes excessive, that a better stand of the young plants can be obtained when the rainfall is moderate than when it is copious. Saturated ground is hurtful to the young plants. They will not grow properly under such conditions and are likely to assume a sickly appearance. Mildew may appear and the plants may fail in patches. And this may happen on land which will ordinarily produce reasonably good crops of alfalfa after they have once been established. The value of alfalfa in providing pasture is more restricted than in providing hay. This arises in part from the injury which may come to the plants from grazing too closely at certain times, and in a greater degree from injury which may result to certain animals which may feed upon the plants, more especially cattle and sheep, through bloating, to which it frequently gives rise. This plant is pre-eminently a pasture for swine. They may be grazed upon it with profit all the season, from spring until fall. No plant now grown in the United States will furnish so much grazing from a given area in localities well adapted to its growth. Swine are very fond of it. Some growers do not feed any grain supplement to their swine when grazing on alfalfa, but it is generally believed that, under average conditions, it is wise to supplement the alfalfa pasture daily with a light feed of grain, carbonaceous in character, as of rye, corn or barley, and that this should be gradually increased with the advancement of the grazing season. One acre of alfalfa will provide pasture for 5 to 15 head of swine, through all the grazing season, dependent upon the degree of the favorable character of the conditions for growth in the alfalfa, the age of the swine, and the extent to which the pasture is supplemented with grain. But in some instances the area named will graze at least 15 hogs through all the growing season without a grain supplement. Swine may be turned in to graze on alfalfa when well set, as soon as it begins to grow freely in the spring. It should be so managed that the grazing will be kept reasonably tender and succulent. For swine pasture the plants should never be allowed to reach the blossoming stage. This can be managed by running the field mower over the pasture occasionally when the stems are growing long and coarse. Close and prolonged grazing by swine will tend to shorten the period of the life of the alfalfa. The extent to which this result will follow will depend upon soil and climatic conditions and the closeness of the grazing. To avoid such a result and also to secure the utilization of the food to the utmost, some growers advocate cutting the alfalfa and feeding it to swine as soiling. The advisability of handling it thus will be dependent to some extent on the relative price of labor.
