maintain the flow of milk to feed some grain in connection with the 



coarse fodders and the following mixtures will be found desirable. 



I. II. 



3 to 4 quarts of gluten feed daily. 100 pounds gluten meal. 



200 pounds fine middlings. 



125 pounds wheat bran. 



Mix and feed 4 to 5 quarts daily. 



III. IV. 



150 pounds gluten feed. 100 pounds fine middlings. 



75 pounds wheat bran. 150 pounds dried brewers grains or 



Mix and feed 4 to 5 quarts daily. malt sprouts. 



Mix and feed 4 to 5 quarts daily. 



When 50 pounds of clover are fed daily the quantity of these 

 mixtures may be diminished about one-third, 



E. COMPOSITION AND DIGESTIBILITY OF FORAGE 



CROPS. 



The following table is divided into two parts : one headed co7npo- 

 sition, represents the total percentages or pounds in 100 of the dif- 

 ferent ingredients contained in the various fodders, and the other 

 headed digestihility ^ shows the percentage or pounds in 100 actually 

 digestible. The table is made up partly from the analyses and diges- 

 tion work carried out at this station and partly from other sources.* 

 In many cases the analyses and digestion tests are too few in num- 

 ber to secure any very satisfactory averages. Single samples of 

 different fodders show quite noticeable variations in composition and 

 digestibility, depending on weather conditions, fertility of soil, and 

 stage of growth. 



The average analyses of the several gwnjys as presented in the 

 table, give a more correct idea of the probable composition of the 

 cereal fodders, legumes and fodder mixtures, than does the analysis 

 of a single fodder in the group. The same holds true concerning 

 digestibility. 



The table shows as much digestible protein in the cereal fodders 

 as in the fodder mixtures, the latter being a combination of a cereal 

 fodder and a legume. This is due primarily to the difference in the 

 amount of water present. The fodder mixtures naturally contain 

 more protein than the cereal fodders.
