Genetics and Evolution of the Domestic Fowl by Lewis Stevens Pdf
The science of genetics has undergone a period of very rapid and significant development in recent years, and the area of poultry genetics has been no exception. This book provides a balanced and up-to-date account of all the major areas of this subject from Mendelian to modern molecular genetics. The book begins by tracing the evolution of Gallus domesticus from its avian ancestors. Subsequent chapters cover important aspects of poultry genetics, including cytogenetics, transmission genetics, gene mapping, sex linkage, lethal genes, genetics of feathering and plumage, and quantitative genetics. In each chapter, a concise explanation of the genetic principles is followed by a full discussion illustrated by key examples. In the latter part of the book, recent advances in gene cloning and sequencing are examined. The impact of these exciting new developments on our understanding of gene structure and organisation, immunogenetics and the evolution of proteins is assessed. Finally, the uses of transgenic techniques and their implications are discussed. This book provides a clear and useful survey of the genetics and evolution of the domestic fowl, which will be of interest to postgraduate students and researchers in the fields of genetics, agriculture and veterinary medicine, as well as to poultry breeders (both commercial and non-commercial).
An Introduction to Form and Feathering of the Domestic Fowl by Brian Reeder Pdf
In this introduction to the genetics of form and feathering of the domestic fowl you will fi nd a straightforward method that allows anyone, beginner or advanced hobbyist, to understand how the major genes of form and feathering come together to create the silhouette that is the hallmark of each breed. Beginning with a discussion of the skeleton genes, then moving to muscling genes, feathering genes and fi nally to comb genes, an understanding of the layers that make the silhouette is revealed. From this system of understanding how the silhouette is formed, one can then understand what really makes one breed unique from another. All of the genes presented herein are found in the commonly seen exhibition breeds and many hobbyists will be familiar with these breeds, but may be less familiar with the genetic factors involved. This volume is a wonderful tool for learning the basis of how the breeds are made, how their respective forms are derived from separate genes of form and feathering, and how those genes all come together to make the one visual impression that we consider a breed. There is in fact no one single gene which makes the form of any given breed. Many genes are required to derive each type and the combination of those many genes creates the silhouette. As you will see from the many silhouette illustrations in this book, once you know a breed, it is instantly recognizable from its silhouette alone. In addition to the discussion of the genes, there is a discussion of basic genetic concepts and of the complex and often confusing method of quantitative selection that is very applicable to many of the genes described herein. This book presents a very clear system for learning about the genetics of form and feathering in the domestic fowl and is written to be understood by the young and beginners alike.
Poultry Genetics, Breeding, and Biotechnology by W. M. Muir,S. E. Aggrey Pdf
This comprehensive research book represents the first complete integration of current knowledge in this area. It addresses issues associated with poultry breeding particularly by examining quantitative and molecular genetics and the uses of transgenic technology. A special section covers the important area of disease resistance and transmission.
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.
Breeding gamefowls is a complex and intricate process that requires a solid understanding of the principles of genetics. You need to grasp how DNA works and how it determines the traits of your gamefowls. DNA is a molecule that stores the information for the development and function of living organisms. For instance, human DNA contains the instructions for all the characteristics of a person. Gamefowl DNA operates in a similar way. Genes are segments of DNA that code for specific traits. We learned about genes in school and how they are inherited from parents to offspring. Different breeding methods aim to manipulate the genes of gamefowls to produce desirable outcomes. However, breeding is not a random or arbitrary activity. It is a scientific and systematic approach that involves careful planning and prediction. You can experiment with different combinations of gamefowls, but you can only achieve success if you can anticipate the results with reasonable accuracy and minimize the risks. The purpose of this eBook is to educate the average gamefowl enthusiast, as well as the beginner breeder, on how to select gamefowls based on their genetic potential, how to weigh the advantages and disadvantages of different breeding methods, and how to apply the best breeding method for gamefowls according to the author’s opinion.

Poultry Meat and Egg Production by Carmen Parkhurst,George J. Mountney Pdf
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. Craig, Kansas State University; Dr. K. Goodwin (retired), Pennsylvania State University; Dr. T. L. Goodwin, University of Arkansas; Dr. G. C.
Poultry Feathers and Skin by Oluyinka A Olukosi,Victor Olori,Ariane Helmbrecht,Sarah Lambton,Nick French Pdf
The feathers and skin in birds are the first line of defence, but are also important in helping the bird to maintain a stable internal temperature, facilitate integral mobility and ensure successful mating in some species. For poultry, the physical conditions of feathers and skin are important barometers to assess the impact of management and ensure health and welfare. Based on the proceedings of a recent symposium, this book documents the significant developments that have been made in our understanding of the importance of the integument to poultry species. The book: Traces the development of the integument over time and discusses our current understanding of its embryonic development. Includes a broad range of studies covering genetics, welfare, health, nutrition, and management. Promotes research opportunities in an under-studied field. Providing a comprehensive yet concise summary of the available research, this book is an invaluable resource for both the poultry industry and for researchers in animal science and welfare at undergraduate and graduate levels.
