Milk producers who know it best concede that alfalfa is an invaluable feed in the dairy, closely akin to wheat bran in results and usually much less expensive. In the average small town or city there is about one cow for every ten or fifteen people. Therefore, in a town of one thousand population, there will probably be seventy-five to one hundred cows. If alfalfa will increase the quantity of their milk and butterfat, giving a product at a lower cost than the concentrated foods, it should be more used. But as yet it is not generally used, because it is not understood and appreciated. The best time to secure a supply is when it is being harvested and can be taken directly from the field. If the mow is large enough for three or more tons, a ton can be stored from each of the different cuttings, and be cured in superior condition almost regardless of the weather. It would be found a most economical feed for the family cow and, if fowls are kept, it could constitute one-third of their ration, adding to growth and to the egg supply. A CHEAP FEED FOR HORSES The larger users of hay in the towns and cities are liverymen, deliverymen and teamsters. These have been unacquainted with or doubtful of the utility of alfalfa and have never given it a fair trial, or possibly any trial at all. Those who have used it and thought its effects harmful have perhaps not understood its highly nutritious character and may have fed it in too large quantities. Having such a large protein content it should not be used with the same prodigality as prairie hay. For driving horses it should be cut when more matured than for other stock, or when about half in bloom, and should be well cured. Fed then, in reasonable rations of from ten to twenty pounds a day, livery horses may be kept in vigorous thrift with a small additional quantity of grain, and thus a saving be made of twenty to thirty per cent in cost of maintenance. In the alfalfa districts there may be found many liverymen who, having had experience with alfalfa hay, feed their horses little of anything else. In the last few years there has been a growing demand for alfalfa hay for southern towns and cities. The coat and general appearance of horses fed alfalfa are improved, as compared with those fed timothy or prairie hay and the tendency to constipation and indigestion is greatly lessened. It is rarely that an alfalfa-fed animal of any kind is constipated. _CHAPTER XX._ Alfalfa in Crop Rotation MAINTAINING FERTILITY
