276 LEGUMINOS^ IN THE FEEDING OF LIVE STOCK 



digestible proportion and we shall have the unit of fat, the 

 unit of protein, and the unit of carbohydrates. 



Let us take as an example the yellow cowpea, the value 

 of which is Rs. 3.18 per 100 kilos of hay.

Ever since the pioneers of the science of rational feeding 

 attributed a preponderance of value to protein, the other 

 matters Avere regarded as inferior, and for a time even the 

 cellulose and the woody portion of the plant were considered 

 to be useless. However, experiments on the digestibility of 

 nutriments founded on the difference in the analysis of 

 fodders eaten and of the excrement resulting from these 

 fodders, that is to say, from the portion assimilated, showed 

 that, in classes of more or less coarse fodders, a portion 

 of the cellulose was converted into sugar and thus digested. 

 Further, the whole of the carbohydrates did not enter into 

 the organism. These facts having been established the total 

 assimilable cellulose and carbohydrates were thenceforward 

 included in feeding tables under the designation of digestible 

 nitrogen-free extract. 



We have, therefore, in the appended tables, taken these 

 facts into account in estimating the non-nitrogenous matter.
