As with many new technologies, the comprehensiveinformation related to omics is lacking. In this book, we have summarized information about how omics-based approaches are causing paradigm shifts in various research areas of biological sciences. The book contains 11 chapters that cover all major aspects of omics-related research methods. The book begins with an overview of the omicsbefore moving on to contemporary omics approachesand theirapplications in various research areas such asgenomics,transcriptomics, proteomics,toxicogenomics, metabolomics, andnutrigenomics, etc. We also discuss how these new technologies are causing paradigm shifts in research related to animal sciences and human disease research. This resource provides a comprehensive overview of the present state of integrated omics research and medicine, with topics ranging from nutrition and animal traits improvementto human diseases such as cancer. The book brings together recent advancements in the omics fieldto create a cutting-edge framework for this discipline. Providing a complete perspective, we also highlight obstacles that are hindering the broader implementation of these omics technologies. We allow the reader to become acquainted with research trends in omics and an understanding of the quality controls and filtering of high throughput sequencing data in omics as well as implementation of omics in various research areas of biology.
