Epizootiological and Clinical Efficiency of a Trigger-Factor–based Integrated Prevention Approach for Controlling Necrobacteriosis in High-Yielding Dairy Cattle

This study systematically analyzes the key trigger factors influencing the development of necrobacteriosis in high-yielding dairy cattle. The disease was considered a multifactorial pathological process formed under the influence of both endogenous and exogenous factors. Hoof rot, interdigital dermatitis, metabolic imbalances, and technological stressors were identified as the principal risk factors. An integrated prevention model targeting these trigger factors was developed and evaluated under field production conditions. The results demonstrated a reduction in the incidence of necrobacteriosis, stabilization of the clinical condition, and preservation of milk productivity. The findings confirm that a trigger-factor–based integrated approach is highly effective for the control of necrobacteriosis in high-yielding dairy cattle.
