Digestibility of the constituents of various fodders—Continued.

In this table the maximum and minimum amount digested of each constituent in various experiments are given, together with the probable mean. How much we may depend on these determinations for our American fodders is doubtful. They serve, however, to show in what direction we must work, and what assistance chemistry can render the farmer.

To show how these tables are used in connection with fodder analyses an example may serve. A farmer has a milch cow which he wishes to feed in the most economical manner on the fodder at his disposal, combined with other food purchased, and with a view of obtaining the best return in milk. It has been found that a milch cow requires, as a daily ration, for every 1,000 pounds live weight, according to Kühn

The farmer has an average (German) hay and mangolds, which, if fed together, would make a ration too rich in carbohydrates. Taking into consideration his ability to purchase, he finds from the analyses, digestibility and fodder value, that he can make this up in the best way by buying cotton-seed meal and constituting the ration as follows:

Age and condition.

Of course, it is necessary that a farmer's judgment should be used in the matter as well as the mere data given in the tables. The ration must be palatable to the animal and in proper form.

Wolff's tables of the composition, digestibility, and value of feeding stuffs, and his table of feeding standards, are copied here from the admirable report of the Connecticut Agricultural Experiment Station. They are not so good as those given by Kühn in Mentzel und Von Lengerke's Landwirthschaftliches Kalender für 1880, but are more concise. It must always be remembered that these figures are derived from German experiments, and will probably be modified in the future for this country. Feeding standards.
