Scientific bases of animal breeding and genetics were developed in the mid-20th century and were mainly established upon performance recording and reproductive management, with solid statistical foundations. Organized over these principles, breeding programs resulted in significant genetic progress in all animal species. However, dramatic changes have occurred in animal breeding over the last decades, with major developments in areas such as molecular genetics and genomics, which have opened entirely new possibilities for animal genetic improvement. The challenge nowadays is to bring together the quantitative and genomic perspectives in a realistic and efficient way, and transmit this new perception in a consolidated format, exploring the potential that may result from these innovations, but also addressing their possible shortcomings and the ethical considerations involved in their application.

Animal Breeding in the Age of Genomics bridges the gap between conventional Animal Breeding and the new possibilities allowed by recent developments in Genomics, using a practical and applied perspective. The optimization of animal genetic improvement programs becomes crucial, enabling breeders to select for desirable characteristics using the more appropriate tools, thereby enhancing sustainability and productivity in agriculture while considering the environmental impact of animal production. Also, with the increasing recognition of biodiversity's importance, a comprehensive effort is necessary to ensure conservation efforts aimed at maintaining endangered breeds and species, thus helping to preserve genetic diversity, which is crucial for long-term viability and ecosystem resilience.

This book is a great resource not only for undergraduate and postgraduate students, but also for professionals, researchers, educators, and policymakers, fostering a deeper understanding of the importance of animal genetics and how it can address consumer demands, while enhancing animal welfare, environmental sustainability, and food security.
