Here we have a definite quantity of nutritive matter, that 

 was found capable of supporting an ox, now if from any com- 

 bination of food we are able to supply this amount of digestable 

 matter we may be tolerably certain, that the results will be satis- 

 factory, for an animal that is standing still in a warm stall. A 

 majority of farmers, however, do not care to feed simply for 

 maintenance, but want growth, or milk, or wool, the same meth- 

 od of investigation has been applied to all cases, cows giving 

 milk were fed on various combinations of such fodders as the 

 German farmers produce, after many trials those rations, which 

 seemed to be best adapted were taken as standard, and when 

 their value was established by enough trials, the food was analy- 

 sed and the same method of computation applied, as in the case 

 above tabulated. In the same way fattening cattle, horses at 

 work and resting, cows not in milk, growing cattle, swine, etc., 

 have been experimented on and standard rations established. 



Two tables are necessary in computing rations, one showing 

 what quantity of albuminoids and ?ion-n.trogenous, material, is re- 

 quired daily by various animals for each one thousand pounds 

 of live weight, the other showing the composition of the digest- 

 ible part of all the foods that the farmer is likely to have at 

 hand. 



In these tables I have carried out the modification explain-
