PKEFACE 



This volume is an outgrowth from a class manual written 

 several years ago by the author for the use of elementary stu- 

 dents at the University of Illinois in a general course in stock- 

 feeding. Inasmuch as there has been some little demand for 

 the class manual from outside sources, the author has rewritten 

 the original manuscript and added a number of valuable illus- 

 trations and tables. 



An effort has been made to present the scientihc facts under- 

 lying the art of feeding animals in such a manner that the book 

 will not only be suitable for use as a text for college courses in 

 general feeding, but will also be valuable to the farmer who 

 has not had a technical education in agriculture. Thus it has 

 been deemed wise to omit many minor details and a large part 

 of the mass of experimental data from which the general con- 

 clusions are deduced. 



In the first six chapters the author has discussed the scien- 

 tihc aspects of the subject and has attempted to present them 

 in a simple, concise manner so that they may be easily under- 

 stood, not only by the student but also by the feeder who 

 desires to familiarize himself with the scientific principles 

 underlying the art of stock-feeding. A large number of draw- 

 ings and photographs illustrating points in the discussion 

 should be of great value in this connection.
