8 PREFACE 



ravages of infectious diseases, and the scientific basis for 

 the restriction placed upon the importation of live stock. 



The prominence which poultry breeding has attained as 

 a specialty, added to the widespread importance of raising 

 fowls in both country and town, demands the space given 

 to this section of the book. No aspect of animal husbandr}' 

 requires more study of the fundamental principles of breed- 

 ing, feeding, and marketing than does that of poultry. 



All these essential elements of successful live stock farm- 

 ing make the study of animal husbandry one of especial 

 interest not only to those who actually engage in farming 

 but also to those who must depend upon agriculture for 

 sustenance. 



This volume has been prepared with the hope that its 

 pages will, in some measure, meet the needs of students 

 of animal husbandry and create a deeper interest in the 

 live stock industry.
