The dependency on animal biotechnology in livestock industries has been increased in the recent past. The livestock production research has witnessed remarkable developments on biotechnological methods to produce the elite animal breeds. The global animal food requirement has been steadily increasing, and animal production needs to be increased as per the global needs. This book covers various aspects of animal biotechnology such as, reproductive biotechnologies in sheep and goats, oogenesis and folliculogenesis and ovarian disorders. This book focusses the discussion on proteomics and metabolomics, and separate chapters were dedicated to discuss these topics. The proteomics studies of animal viruses were discussed in this book, and this would be helpful to understand animal viral pathogenesis. The applications of metabolomics in livestock were discussed with focus on data analysis, identification of unknown compounds. The purpose of this book is to provide the recent research trends, and convert all this information to usable guide to professionals, researchers and students who are working the research area of animal biotechnology.
