tion should be given to their manurial value, especially 

 since feeds differ so widely in this respect. 



An illustration of the extent to which feeds differ in 

 their fertilizing or manurial constituents is given in the

 seed meal. The table also shows the value of these con- 

 stituents, which was obtained by rating the nitrogen at 

 15 cents per pound, and the phosphoric acid and potash 

 at 4 l /2 cents per pound. 



TABLE IV. Showing fertilizing constituents in 

 corn and cottonseed meal. 



The table shows that the fertilizing value of a ton of 

 cottonseed meal exceeds that of a ton of corn by $17.30,

Frequency of Feeding. The main part of the ration

 some dry roughage at noon, especially when the roughage 

 in the morning and evening consists of silage. The cow,
