Changes of the regional vascular bed in toes septic diseases of cattle

Abstract

CATTLE In the present work, the results of the research on the study of the anatomical, histological and morphopathological aspects of the blood vessels of the support and movement apparatus are presented, a study stimulated by the requirements of theoretical and practical veterinary medicine, for the correct and effective intervention in the cattle toes region. It has been established that in hidden laminitis the horn of the hoog becomes visibly softer, yellow spots appear caused by the leakage of blood from the vessels into the solar dermis, especially at the white line. Arterioles, under the action of pathological processes that develop in the adjacent tissues, lose their muscle tone and then an acute parietal paresis occurs. In severe forms, there are obvious changes in the vessels walls accompanied by changes in their trajectory architectonics. Due to necrosis and deformations of the horn wall of the hoof and the third phalanx, the arteries flatten dorso-palmar (plantar), which causes a major infiltration of the adjacent tissues, worsening of lameness, increased morbidity, decrease or complete cessation of animal productivity.
