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.
