To develop a comprehensive prevention and control strategy targeting three protozoal parasitic diseases—bovine babesiosis, theileriosis, and coccidiosis—aimed at reducing incidence rates and mitigating drug resistance risks.

This study systematically investigated the epidemiological characteristics, typical clinical symptoms, and laboratory diagnostic techniques of the three protozoal diseases. By integrating vector control, precision medication, and immunization strategies, Combining pathogen detection with field practice to formulate an operable scheme.

A trinity system encompassing "diagnosis-treatment-prevention" was proposed for cattle farms of varying scales. This system achieved reductions incidence rates and controlled drug resistance risks, thereby supporting the sustainable development of the cattle industry.

The integration of technology and practical application significantly enhanced the efficiency of bovine protozoal disease management, providing a scientific basis for farm management practices.
