Monitoring the prevalence of laminitis and white line pathology in cows at a university dairy farm

The incidence of orthopedic pathology in the farm in 2023 was characterized by a significant prevalence of various forms of hoof deformities in part of the cow population (40,3 %). The dominant pathology was pododermatitis (13,1 %) and ulcerative processes (17,5 %). The causes of pododermatitis were often mechanical injuries. Various nosological forms were detected during primary orthopedic dispensary examination. The spread of ulcerative processes is often due to the presence of chronic irritation of the toe area and interdigital gap due to insufficient compliance with sanitary conditions, untimely removal of manure, unsatisfactory condition of the stables and high humidity. According to clinical examinations of cows, ulcerative processes in the hoof area were characterized by destruction of the epithelial cover and the development of local purulent infl ammation [12, 13]. At the same time, the prevalence of signs of laminitis and white line lesions was at the level of 4,4 %. The results of the medical examination for 2024 and 2025 showed the effectiveness of the complex of measures implemented on the farm. In particular, the established systematic orthopedic treatment and treatment allowed to signifi cantly reduce the prevalence of cases of deformities to (21,7 %) and (22,4 %), respectively. The number of cases of pododermatitis and ul cerative processes also decreased signifi cantly. At the same time, the data indicating a probable increase in the pathology of the white line area from 4,4 % in 2023 to 5,7 % in 2025 are alarming. A potential risk factor for the development of white line pathology is often the penetration of a foreign object through the hoof horn to the base of the skin under the white line, which can cause a local bacterial infection. The results obtained confirm that a well-founded hoof care program, timely trimming, including preventive measures, is of signifi cant importance in the prevention of hoof diseases, as it allows to signifi cantly reduce the percentage of animal culling due to orthopedic pathology.
