III. IV. 



75 lbs. bran. 150 lbs. bran. 



150 lbs. corn and cob meal. 200 lbs. gluten teed. 

 75 lbs. cottonseed meal. 



V. VI. 



200 lbs. dried brewers' grains. 200 lbs. dried distillers' grains. 



100 lbs. corn or hominy meal. 150 lbs. flour middlings. 

 50 lbs. gluten feed. ' 50 lbs. corn meal. 



The selection of the particular ration to be used will naturally de- 

 pend upon the presence and cost of the several grains in the local 

 markets. 



E. COMPOSITION AND DIGESTIBILITY OF FORAGE CROPS. 



The following table is divided into two parts. One headed 

 cotnposition, represents the total percentages or pounds in loo of the 

 different ingredients contained in the various fodders, and the other, 

 headed digestibility, shows the percentage or pounds in 100 acinaUy 

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

 tion work carried out at this station, although other sources have 

 been drawn from when necessary.' In many cases the analyses and 

 digestion tests are too few in number to secure any very satisfactory 

 averages. Single samples of different fodders and fodder mixtures 

 show quite noticeable variations in composition and digestibility, de- 

 pending on weather conditions, fertility of soil, and stage of growth. 



The average analyses of the several groups 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.
