I. Tables of Composition and Feeding Standards. 



129. Nutrients of feeding stuffs. We have already learned how 

 the chemist divides the constituents of feeding stuffs into groups, 

 which are placed in tables for convenient reference. From Table 

 I of the Appendix there is here abstracted the fragment marked 

 Example Table A, for the purpose of discussing the subject 

 of nutrients in feeding stuffs. 



Example Table A, showing the water and total nutrients found by the 

 chemist in several common feeding stuffs. 



In tables of this character the results stated are always the 

 average of all analyses for each feed on record at the time of com- 

 pilation. 



The table shows that 100 pounds of average field- cured fodder 

 corn contain 40.5 pounds of water a much larger amount than 

 the feeder will, on first thought, suppose possible in what he has
