Ho^ is a cattle feeder to learn whether his rations compare with 

 the above standards? He must ascertain the composition of his 

 foods and their digestibility ; in other words, he must know how 

 much of different ingredients his cattle are eating and what propor- 

 tion of them is available for use. It is not possible for each farmer 

 to have his feeding stuffs analyzed, but we have tables giving the 

 average composition of a large list of cattle foods as determined by 

 numerous analyses, and the same for the percentages of digesti- 

 bility, and a calculation made for any given food by means of these 

 averages is perhaps accurate enough for practical purposes.
