ABSTRACT FROM THE PREFACE TO THE 

 FIRST EDITION 



In accordance with the great practical importance of a knowledge 

 of feeding and of injurious feed admixtures I have devoted liberal 

 space to this department of veterinary hygiene. The principles of 

 feeding as elaborated in this work have been based upon the epoch 

 making labors of Kellner who has directed the study of this science 

 into new channels. The kindness and obligingness of Prof. Dr. Kell- 

 ner and of the Publishing House of Paul Parey has made it possible 

 to include the tables on the composition, digestibility and starch value 

 of feeding stuffs to which I have added for the sake of handy reference 

 the digestible albumen and starch value ratios as well as the table of 

 condensed feeding standards. I consider it a pleasant duty to express 

 my sincere thanks for the kind permission granted to publish these 

 tables. 

 Dresden, in the fall of 1917. 



ABSTRACT FROM THE PREFACE TO THE 

 SECOND EDITION 



In revising this work it has been my endeavor to correct any exist- 

 ing shortcomings of the first edition which have been kindly pointed 

 out by my critics, and further, to make such changes and additions as 

 recent investigations and discoveries demanded. 

 Dresden, November, 1913. 



PREFACE TO THE THIRD EDITION 



The recent decision in favor of the separate consideration of the 

 study of feeding and veterinary hygiene in the college courses of 

 veterinary medicine and in state examinations has been the motive for 

 the publication in two separate volumes, "Veterinary Hygiene" and 

 "Scientific Feeding of Animals," of my former work which was pub- 

 lished under the common title of "Veterinary Hygiene."* Whether 

 this division and separate consideration of the subjects was practical 

 and necessary is a matter concerning which differences of opinion may 

 well exist. I regret it. 



The fact remains that animal nutrition is one of the most important 

 branches of the study of veterinary hygiene. A sharp distinction be- 

 tween these two divisions is not always possible.

 and enlarged edition. With 270 illustrations. About 440 pages. Berlin. 1921.
