  • Broiler Chickens
    The Life of: Broiler Chickens Chickens reared for meat are called broilers or broiler chickens. They originate from the jungle fowl of the Indian Subcontinent. The broiler industry has grown due to consumer demand for affordable poultry meat. Breeding for production traits and improved nutrition have been used to increase the weight of the breast muscle. Commercial broiler chickens are bred to be very fast growing in order to gain weight quickly. In their natural environment, chickens spend much of their time foraging for food. This means that they are highly motivated to perform species specific behaviours that are typical for chickens (natural behaviours), such as foraging, pecking, scratching and feather maintenance behaviours like preening and dust-bathing. Trees are used for perching at night to avoid predators. The life of chickens destined for meat production consists of two distinct phases. They are born in a hatchery and moved to a grow-out farm at 1 day-old. They remain here until they are heavy enough to be slaughtered. This document gives an overview of a typical broiler chicken’s life. The Hatchery The parent birds (breeder birds - see section at the end) used to produce meat chickens have their eggs removed and placed in an incubator. In the incubator, the eggs are kept under optimum atmosphere conditions and highly regulated temperatures. At 21 days, the chicks are ready to hatch, using their egg tooth to break out of their shell (in a natural situation, the mother would help with this). Chicks are precocial, meaning that immediately after hatching they are relatively mature and can walk around.

  • United States V. National Broiler Marketing Association: Will the Chicken Lickin’ Stand?
    University of Arkansas · School of Law · Division of Agriculture [email protected] · (479) 575-7646 An Agricultural Law Research Article United States V. National Broiler Marketing Association: Will The Chicken Lickin’ Stand? by Charles Gordon Brown Originally published in NORTH CAROLINA LAW REVIEW 56 N.C. L. REV. 29 (1978) www.NationalAgLawCenter.org UNITED STATES V. NATIONAL BROILER MARKETING ASSOCIATION: WILL THE CHICKEN LICKIN' STAND? CHARLES GORDON BROWNt Most of the nation's major broiler! producers are skeptical of the wisdom of the old adage "build a better mouse trap and the world will beat a path to your door." The broiler industry built a better mouse trap all right. Sweeping technological and organizational innovations have transformed the industry into one of major agricultural importance. From a meager $19 million in 1934,2 gross farm income from broilers soared to $2.9 billion in 1975,3 a more than fifteen hundred percent increase in just four decades. The remarkable growth of the industry has been accompanied by an even more remarkable phenomenon: broilers are cheaper today than ever before, despite escalating production costs,4 because the efficiency of the industry has kept prices low. 5 The broiler industry's mouse trap has been so success­ ful, in fact, that it has become a model for other areas of agricultural production.6 But the news is not all good. Among those beating a path to the broiler producers' doors was the Antitrust Division of the United States Department t Visiting Assistant Professor of Law, University of North Carolina School of Law; B.A.

    THE ft^^^^^ CHICKElsf BROILER INDUSTRY: STRUCTURE, PRACTICES, AND COSTS Agricultural Economic Report No. 381 -33 UNITED STATES :V, DEPARTMENT OF AGRICULTURE ECONOMIC RESEARCH SERVICE THE CHICKEN BROILER INDUSTRY: STRUCTURE, PRACTICES, AND COSTS. By Verel W. Benson and Thomas J. Witzig, Conunodity Economics Division, Economic Research Service, U.S. Department of Agriculture, Agricultural Economic Report No. 381. This report updates "The Chicken Broiler Industry: Structure, Practices, and Costs," Marketing Research Report No. 930, published in May 1971. ABSTRACT Extensive changes in production, processing, and marketing during the last few decades have changed the chicken broiler industry from one of small, widely scattered farms to one that is large, concentrated, and efficient. More than 99 percent of all broilers produced are grown under contract and by integrated firms which vary in size of operation and complexity. About 84 percent of all production is concentrated in 10 States. Some of the other factors that contributed to these changes are costs, energy use, prices, processing, marketing, and demand. Keywords: Broilers, consumption, costs, demand, energy, marketing, processing. ACKNOWLEDGMENTS The authors wish to acknowledge the assistance of George B. Rogers, William L. Henson, Harold B. Jones, and Leonard A. Voss for contributing data and written materials which are integral parts of the sections on production and marketing costs, energy use, and interregional shipments of broilers.
