Preface and Acknowledgements 



This bulletin is the seventh in a series being issued by the 

 Agricultural Experiment Station, University of New Hampshire, 

 in cooperation with the Agricultural Experiment Station, Uni- 

 versity of Massachusetts, and the Economic Research Service, 

 United States Department of Agriculture. 



The series is concerned with various aspects of poultry 

 marketing in New England. Previous publications in the series 

 with their New Hampshire Experiment Station Bulletin numbers 

 are: 1. Characteristics of the Processing Industry (444), 2. Eco- 

 nomies of Scale in Chicken Processing (450), 3. Capital Accumu- 

 lation Potential of Broiler Growers (475), 4. Structure and Per- 

 formance of the Assembly System (476), 5. Effects of Firm Size 

 and Production Density on Assembly Costs (482), 6. Economies 

 of Scale in Hatching and Cost of Distributing Broiler Chicks 

 (483), and 8. Effects of Firm Size and Production Density on 

 Spatial Costs for an Integrated Broiler Marketing Firm (485). 

 Two companion reports published by the Agricultural Experi- 

 ment Station, University of Massachusetts, are Freight Rates 

 on Feed, Central Territory Origins to New England and Middle 

 Atlantic States (508) and Freight Rates and the Eastern Poultry 

 Industry (533). 



The objectives of this study are to determine the costs of 

 mixing ])roiler feed and economies associated with size of feed 

 mixing firms. Also determined are the costs of delivering the feed 

 and how these costs are affected by changing 1) firm size (vol- 

 ume), 2) delivery density (tons per square mile), and 3) dis- 

 tance. 



The authors appreciate the cooperation of the mill operators 

 who provided information .and data on input-output relation- 

 ships and costs; also those manufacturers and suppliers of mill- 

 ing equipment who furnished data on specifications, capacities 

 and costs. The authors acknowledge the assistance received from 

 William F. Henry and other members of the Resource Economics 

 Department, University of New Hampshire, and George B, Rog- 

 ers, Marketing Economics Division, Economic Research Service,
