ANALYSES OF FEEDSTUFFS
The following table gives the analyses of a number of feedstuffs, showing the percentage of digestible nutrients and fertilizing constituents in each:

RELATIVE VALUES OF DIFFERENT CUTTINGS
The most interesting experiments comprehending tests of the comparative yield, composition and digestibility of early, medium and late cuttings of alfalfa, of the first, second and third crops; the relative feeding value of the various cuttings, and of the different crops, have been made at the Utah station, details of which are recorded in the station’s bulletins Nos. 31, 44 and 61. These tests and investigations extended continuously through a period of five years, and following are the more important facts developed and the conclusions that may be legitimately drawn from them, as summarized (Bul. No. 61) by Profs. Luther Foster and L. A. Merrill who supervised the work:
1. The largest annual yield of hay per acre is obtained by the method of early cutting and the lowest by the late, the average result standing as follows: early cutting, 100; medium, 92; and late, 85.
