Textbook on Animal Genetics and Breeding

This book is designed as a comprehensive academic and practical reference for animal scientists, veterinarians, B.V.Sc. A.H. students, researchers, livestock professionals, and progressive farmers. It explains the science of animal breedingapplying genetic and reproductive principles to improve populationsand emphasizes the importance of selection and mating strategies in achieving long-term genetic gain.

Across 39 well-structured chapters, the book covers foundational and advanced topics including Mendelian genetics, cytogenetics, Hardy–Weinberg law, linkage and population forces, phenotypic variance components, breeding value, heritability, repeatability, genetic correlations, selection indices, and expected genetic progress. It also discusses breeding strategies for cattle, buffalo, sheep, goat, swine, and poultry, national breed improvement programs, breed classification, and the integration of molecular tools with traditional breeding approaches.

The subject matter is presented in a logical progression, enabling readers to move seamlessly from basic concepts to their practical applications. While extensive care has been taken in preparing mathematical expressions, illustrations, and diagrams, minor inaccuracies may remain, and readers are encouraged to share suggestions for future editions. Some figures sourced long ago could not be traced to their original references, and any inadvertent omissions may be communicated for rectification.

This book represents years of teaching, research, and practical experience, offering a dependable resource for strengthening knowledge in animal genetics, breeding, and livestock improvement.
