vi PREFACE 



On account of the " back to the land " movement which is 

 sending men from the cities to the agricultural colleges and to 

 the farm, a mere discussion of balanced rations and feeding 

 standards has not seemed sufficient. Consequently the author 

 has presented rather definite rules regarding the feeding of 

 the different classes of live stock which, taken in connection 

 with the feeding standards and the discussion of the nutritive 

 value of the different feeds, should enable the inexperienced 

 feeder to formulate at least fairly satisfactory rations. This 

 point has also been kept in mind in treating of the feeding 

 values of the different feeds, and an attempt has been made to 

 make specific rather than general statements regarding the 

 amounts, proportions, and combinations of feeds in the rations 

 of different classes of farm animals. It has also seemed of 

 value to insert illustrations of the principal crops used for 

 feeding. 



It has seemed desirable, partly in order to avoid duplication, 

 to discuss the use of each of the principal feeds for the differ- 

 ent species and classes of live stock rather than to devote 

 separate chapters to the feeding of the different classes of farm 

 animals. For example, under the discussion of corn, its use is 

 given in the rations of growing cattle, colts, pigs, and lambs ; 

 fattening cattle, hogs, and sheep ; breeding cattle, horses, hogs, 

 and sheep ; dairy cows ; and work horses. 



In addition to the discussion of the nutritive value of feeds 

 and rations, the author has given particular attention to their 

 fertilizing values, a phase which is often neglected both by the 

 student and the stockman.
