The bookis a specialized academic resource that offers in-depth knowledge on protozoan parasites affecting the health and productivity of dairy livestock. This book serves as a valuable reference for students, researchers, veterinarians, and dairy professionals concerned with animal health, parasitology, and herd management.The text begins with a foundational overview of protozoa, with specific chapters on key haemoprotozoan parasites such as Trypanosoma, Theileria, Babesia, and Anaplasma. It then explores modern diagnostic techniques for detecting infections, including molecular and serological approaches.Further chapters address critical issues like antiprotozoal resistance, the impact of nutrition on parasite prevention, and general dairy farm management practices aimed at controlling parasite transmission. With an emphasis on both the biological understanding and applied strategies, this book integrates scientific principles with field-relevant practices.Structured to support both academic learning and on-farm decision-making, the book promotes a holistic approach to prophylaxis, diagnosis, and control of haemoprotozoan infections—contributing to sustainable dairy farming and improved animal welfare
