THE FEEDING OF ANIMALS 



TABLE LXXXIX. RELATION OF FOOD TO PRODUCT 



*Extending over seven years. 



tShort periods. 



Deduced from compilation by Dr. Armsby for U. S. Dept. of Agriculture. 



JDry matter, mostly from milk, practically all digestible. 



II Unpublished data from experiments at the New York Agric. Exp. Station. 

 **4.35 Ibs. dry matter, assumed to be 80 per cent digestible. 

 ttEgg product, 100 eggs per year. 

 85.7 Ibs. dry matter, assumed to be 80 per cent digestible. 



The figures of the foregoing tables can be regarded 

 as being trustworthy for average conditions. They are 

 obtained from the recorded data of experiment stations, 

 and involve a large number of observations with dairy 

 cows and with growing and fattening animals. 



In most cases the amount of digestible matter in the 

 ration is calculated from the average coefficients of 

 digestibility. 



The facts brought out by this study of the relation 

 of food to product are emphatic and suggestive. In 

 order to display them as clearly as possible there are 

 shown in the next table the quantities of the various
