Prevalência, características clínicas e epidemiológicas das enfermidades podais em vacas lactantes da bacia leiteira do município de Rondon do Pará

Abstract

In order to determine the prevalence, clinical classification and establish the epidemiological factors of foot diseases in dairy cows of properties located in the municipality of Rondon do Pará, 1.236 cows were evaluated, of whom 275 had at least one type of foot injury and 655 lesions were identified noting a prevalence of 22.25%. The diseases most frequently diagnosed were: interdigital hyperplasia, accounting for 80.92%, followed by diffuse septic foot pad dermatitis with 6.11%, growth over the quarter with 3.82%, hull with form of scissors with 2.60% and paradigit dermatitis with 2.44%. Pelvic members were most affected with 61.83% of total injuries, and the interdigital space, in both thoracic limbs with 36.34% and 48.09% in the hindlimbs where the digital region were affected more frequently. The epidemiological study showed that the environmental characteristics (mountainous, grassland in training with the presence of trunks and branches of trees, irregularities in the floor pens, the presence of mud and gravel) promote the development of foot lesions. In 95.5% of the properties studied there is no measure of control and prophylaxis in relation to diseases that affect the hull. The specific clinical examination of the hull was efficient to diagnosis of diseases.
