Paperback. Etat : New. Print on Demand. This book explores the genetic basis of economically valuable traits in poultry and demonstrates the application of this knowledge to selective breeding for improved production and viability. The author begins with a brief history of poultry breeding, highlighting the work of Pearl, Gowell, and Hays in developing an understanding of the inheritance of egg production. The author then discusses the individual production characters, such as sexual maturity, persistency, broodiness, rate of production, and egg size, and reviews the genetic research on each. The author synthesizes this information to explain how the various characters interact to determine the annual egg record and the overall productivity of a flock. The book concludes with a discussion of the practical application of genetic principles to breeding programs for commercial egg production. The author emphasizes the importance of progeny testing to evaluate the breeding value of individual birds and the use of selection indices to combine information on multiple traits. This book is a valuable resource for poultry breeders and geneticists interested in improving the economic traits of poultry flocks.
