PREFACE 



This book is written for amateur as well as professional livestock and 

 dairy farmers. It makes a popular appeal to all men engaged in animal 

 and dairy husbandry. 



Ages of farm experience have given us a vast store of practical knowl- 

 edge on the raising of crops and animals. This knowledge is scattered 

 through many volumes on different phases of the subject, in experiment 

 station bulletins, agricultural journals and encyclopedias. The important 

 facts on which the most successful livestock and dairy farming is based 

 are here brought together in orderly and readable form. Not only are 

 directions given for the management and care of farm animals but the 

 business end of the problem is fully discussed, showing why some achieve 

 success and why others fail. 



The subject-matter is arranged in several parts of a number of chapters 

 each, and by referring to the Table of Contents any subject may be quickly 

 found. Each department has been prepared by a specialist in the subject 

 presented. The name of the author appears at the beginning of each 

 chapter. Those unacknowledged have been prepared by myself. 



The illustrations have been secured from many sources. Due credit 

 has been given these. 



Special acknowledgment is due the publishers of this volume and 

 the other volumes in the series for its conception, and for many helpful 

 suggestions in the presentation of the subject-matter. 



I wish also to especially acknowledge the valuable editorial assistance 

 of my wife in the preparation of the manuscript.
