THE DIGESTIBILITY OF FEEDINGSTUFFS 75 



The percentage of each nutrient in the feed, multipUed by 

 the corresponding coefficient of digestibihty, and the result 

 divided by 100, gives the percentage of each digestible nu- 

 trient in the feed. If the corn in the example cited on page 

 58 contained 9.80 per cent of crude protein, 82.08 per cent 

 of which was digestible, the percentage of digestible crude 

 protein in the corn would be 9.80 times 82.08 divided by 

 100, or 8.04. In other words, 100 pounds of the corn con- 

 tained 8.04 pounds of digestible crude protein. The per- 

 centage of the other digestible nutrients of the corn may be 

 obtained in similar manner. In the formation of rations, 

 it is the percentage of digestible nutrients which are in the 

 feeds, rather than the percentage of total nutrients which 

 must be considered. The average content of digestible 

 nutrients in feedingstuffs for horses, cattle, and sheep is 

 given in Table 29, of the Appendix. Inasmuch as hogs do 

 not digest their feeds the same as the other farm animals. 

 Table 30, giving the average content of digestible nutrients 

 in feedingstuffs for hogs, is given.
