This book explores the expanding role of biotechnology in animal breeding and the ways in which modern genetic science contributes to the improvement and conservation of livestock populations. It explains how advances in molecular genetics, genomics, and biotechnology have transformed traditional breeding practices by enabling more precise understanding of inherited traits. The discussion highlights how genomic research provides powerful tools for analysing genetic variation in domestic animals and for identifying characteristics associated with productivity, adaptability, and disease resistance. The book also considers the historical development of animal breeding science and the transition from conventional selection methods to genome-based approaches. Particular attention is given to the evaluation of breeding models used to improve multiple traits simultaneously while maintaining genetic diversity in livestock populations. In addition, the text examines the significance of breeding strategies in addressing global challenges such as climate change and the conservation of valuable animal genetic resources.

The work presents an academic overview of biotechnology-driven breeding systems within modern livestock science. It supports advanced study in animal genetics, biotechnology, and sustainable livestock improvement, encouraging informed understanding of genomic approaches in contemporary agricultural research.
