A STUDY OF FARM ANIMALS 



A TABLE OF FEEDING STANDARDS 



The following table is made up from the modified Wolff- 

 Lehman feeding standards, as arranged by Henry and Morri- 

 son. The purpose of this table is to enable one to work out 

 a few easy problems in feeding. For example, if we assume 

 one has a horse at light work, and is using feeds given in 

 table A, then with the aid of table B, he should be able to 

 figure out if the ration fed is supplying the animals' needs. 

 The application of these tables is explained in Chapter IX.
