This collection provides a comprehensive review of recent developments in poultry breeding. The book begins by reviewing the current challenges facing poultry breeding such as genetic diversity and physiological constraints. It goes on to review recent research on the genetics of key traits, from production traits such as egg production to functional traits such as bone strength, and their implications for breeding. The book then summarises key advances in genomic selection techniques and their application in broiler and layer breeding. It concludes by surveying emerging trends such as the use of epigenetics and genome editing in poultry breeding.

Poultry Meat and Egg Production has been prepared primarily for use as a text for students taking their first courses in poultry manage ment. The general overall science and production practices currently in use in the industry have been characterized and described so that the student can gain insight into the industry. Reading portions of chapters before the lecture discussions and laboratory sessions will be helpful in giving students an understanding of the material. Also, this gives the instructor an opportunity to emphasize in the lectures areas of current concern in the industry, and to present topics of his or her choice in greater detail. We wish to acknowledge and thank the following scientists who reviewed and critically evaluated the several chapters and made many helpful suggestions: Dr. Bobby Barnett, Clemson University; Mr. D. O. Bell, University of California; Dr. Donald Bray (retired), University of Illinois; Dr. W. H. Burke, University of Georgia; Dr. Frank Cherms, Nicholas Turkey Breeding Farms, Inc., Sonoma, California; Dr. Wen dell Carlson (retired), South Dakota State University; Dr. J. V.

The diverse area of chicken breeding is essential to supplying the world's expanding need for poultry products. Effective breeding techniques have a major role in determining the quality, quantity, and efficiency of production-whether it's eggs or meat. This chapter provides an overview of the basic ideas, significance, and workings of the chicken breeding industry. The process of carefully selecting and marrying birds to create offspring with desired qualities is known as poultry breeding. Depending on the intended use-egg production, meat production, or display purposes-these characteristics may differ. Improving a chicken flock's total productivity, well-being, and profitability is the main objective of breeding. Genetics is a major factor in chicken breeding. Breeders need to understand poultry genetics in order to choose mating pairings and selection criteria with knowledge. Numerous characteristics, including development rate, egg production, illness resistance, and feather color, are influenced by genes. Breeders may control these genetic features to produce desired results via selective breeding. Choosing birds with desired characteristics and utilizing them as breeding material to carry those features through to future generations is known as selective breeding. In order to guarantee genetic advancement throughout time, this procedure needs meticulous planning, monitoring, and assessment. Selective breeding is often used to increase traits including body weight, feed conversion efficiency, egg size, and shell quality. The effectiveness of poultry breeding projects is largely dependent on breeding strategies. Breeders are guided in their selection processes and breeding tactics by these plans, which lay forth precise aims and objectives. Objectives might include raising the amount of eggs produced, producing more meat, boosting feed efficiency, or producing birds with certain visual traits. Breeders may concentrate their efforts and resources on attaining measurable results by setting defined targets. Another essential component of raising chickens is managing breeding flocks. For breeding birds to be healthy and productive, they need enough shelter, food, and medical care. Specialized care is needed for breeding flocks in order to guarantee maximum reproductive efficiency and high-quality progeny. Enough room, ventilation, temperature control, and defense against illnesses and predators should all be provided by housing facilities. Egg production and reproductive processes depend heavily on nutrition, necessitating balanced meals full of key elements. Using natural breeding techniques, birds are allowed to mate and procreate without assistance from humans. Given that genetic pairings are left up to chance, this procedure, although simple and inexpensive, may not always provide the intended results. With artificial insemination (AI), breeders may deliberately pair birds based on desired features, providing a more controlled breeding environment. Breeders can overcome obstacles like poor fertility or genetic incompatibility by using stronger genetics and AI.

This book reviews the biological science and background to breeding meat poultry, specifically broiler, turkey and duck. These commercial birds have been changed by genetic selection to such an extent that they are substantially different from traditional breeds and laying hens. Covering science, management and husbandry systems, this book is an essential reference for researchers and students in animal science, as well as technical staff of breeding companies and poultry meat producers. Part of the Poultry Science Symposium Series.

Chickens are now the most scientifically engineered of livestock. How have the methods used by geneticists differed from those employed by domestic breeders over time? Art and Science in Breeding details the relationship between farm practices and agricultural genetics in poultry breeding from 1850 to 1960. Margaret E. Derry traces the history and organization of chicken breeding in North America, from craft approaches and breeding as an 'art,' to the conflicts that had emerged between traditional and scientific methods by the 1940s. Derry assesses links between the 'scientific' revolution of chicken farming and the development of corporate breeding as a modern, international industry. Using poultry as a case study for the wider narrative of agricultural genetics, Art and Science in Breeding adds considerable knowledge to a rapidly growing field of inquiry.

Liberating today's chicken from cartoons, fast food, and other demeaning associations, The Chicken Book at once celebrates and explains this noble fowl. As it traces the rise and fall of Gallus domesticus from the jungles of ancient India to the assembly-line hatcheries sprawled across modern America, this original, frequently astounding book passes along a trove of knowledge and lore about everything from the chicken's biology and behavior to its place in legend and mythology. The book includes lively discussions of the chicken's role in literature and history, the cruel attractions of cockfighting, the medicinal uses of eggs and chicken parts, the details of the egg-laying process, the basics of the backyard coop, recipes, and much more. Entertaining and insightful, The Chicken Book will change the way we regard this too often underappreciated animal.
