THE CHEMISTRY OP THE FARM 



We cannot close this section without a word as to 

 standard rations. In fattening it is clearly the farmer*s 

 object to supply the animal with the largest amount of 

 food it can profitably make use of. So long as bulky 

 foods, as hay, straw and roots are largely employed, 

 the animal may safely be given as much as it can eat ; 

 the limits of profitable use must, however, be con- 

 sidered when concentrated foods, as cake and corn, are 

 supplied. Few accurate experiments have been made 

 as to the economy of supplying a more or less con- 

 centrated diet to sheep and oxen. The assimilating 

 power of the pig is so great that there appears little 

 danger of over-feeding in its case. The daily ration's 

 recommended in the German feeding standards for 

 fattening animals by Wolff and Lehmann are as 

 follows : — 



DAILY FOOD PER 1,000 LBS. LIVE WEIGHT. 

 Fattening Oxen. 



Fattening Sheep.
