“…Estudos realizados em bovinos leiteiros mostram que as enfermidades de casco são determinadas por fatores predisponentes relacionados a aspectos ambientais e/ou decorrentes do manejo inadequado (Silva et al 2001, Silveira et al 2009, Albuquerque et al 2009). Pisos de concreto e pedras pontiagudas, exposição de ferragens, tábuas laterais com quinas salientes e estresse dos animais dentro das instalações são fatores que agregam condições favoráveis a acidentes que podem iniciar lesões na pele ou no tecido córneo do casco.…”

“…Piquetes com presença de troncos e galhos de árvores, solos pedregosos e áreas de relevo inclinado observadas com frequência no presente estudo, são fatores ambientais importantes associados à claudicação em bovinos, já relatados no estado do Pará (Silveira et al 2009) e em outras regiões do País (Silva et al 2001, Ferreira et al 2004) e provavelmente também atuaram nos bovinos do presente estudo. Segundo Malafaia et al (2011), no estado do Pará, muitas pastagens foram formadas após intenso e indiscriminado desmatamento, resultando na degradação dos solos e a grande incidência de tocos e troncos, que atuam como obstáculos naturais à locomoção dos animais.…”

“…Outros estudos realizados em bovinos manejados a pasto no estado do Pará registraram doenças digitais em prevalências consideráveis. Silveira et al (2009) identificaram a hiperplasia interdigital como a lesão mais frequente, seguida pela pododermatite séptica e pelo crescimento excessivo dos cascos. Em bovinos manejados semi-intensivamente em Goiás, identificou-se a dermatite digital, seguida pela dermatite verrucosa e pododermatite séptica (Silva et al 2001).…”

“…Além disso, não se devem desprezar os índices crescentes de enfermidades digitais em rebanhos mistos e de criação extensiva (Silveira et al 2008, Silveira et al 2010, Silveira et al 2011. Silveira et al (2009), no estado do Pará, relataram enfermidades podais em bovinos manejados em regime extensivo de produção. Porém, diferentemente do que está sendo proposto neste trabalho, esses estudos estavam diretamente relacionados a bovinos leiteiros.…”

RESUMO.-Foram avaliados os fatores epidemiológicos e as afecções podais de bovinos de corte no estado do Pará em 12 propriedades. Em todas foi realizado o estudo epidemiológico e em nove o estudo epidemiológico e o exame clínico dos animais. Nos centros de manejo foram observados fatores favoráveis a traumatismos nos dígitos dos bovinos, como piso das seringas calçado com pedras, troncos com exposição de ferragens e rampas dos embarcadores com pisos de pedras pontiagudas, além da falta de manutenção e erros estruturais. Em todas as fazendas observou-se um manejo The epidemiological study was conducted in 12 farms with the history of foot disease occurrence. Clinical examination of the affected cattle for the diagnosis of foot disease was performed only on nine of these farms. Multiple risk factors were found for digit injuries, as syringes floors paved with rocks, working chutes with iron fittings exposure, loading ramps covered with sharp stones and the lack of maintenance and structural errors. On each farm there was an inappropriate handling of cattle. On 91.7% of them (11/12) existed pickets with trunks of trees and 66.7% (8/12) had areas of sloping relief with stones. Moreover, 16.7% (2/12) of the farms were in marsh areas and wetlands. Sodomy was reported for all farms. None of them adopted preventive measures related to foot problems. A total of 498 cattle, males and females, were examined. The hind limbs were the most affected in both, females and in males. In females 629 lesions were diagnosed. The septic pododermatitis was the most common, followed by claw deformities, pododermatitis in the paradigits and digital dermatitis. In males 285 injuries were diagnosed; the most common were septic pododermatitis, claw deformities and heel erosion. It was concluded that management errors associated with inadequate facilities were factors that contributed to the occurrence of foot diseases in beef cattle of the farms studied. The environmental characteristics favored the development of lesions; combined injuries were more prevalent than the simple ones diagnosed in cattle of all farms. Early diagnosis was not carried out in the field, what helped to increase the severity and the diversification of the foot problems.

“…Laminitis is pointed out as the cause of 62% of lameness cases in dairy cows (Nocek 1997), is highly prevalent in cows subjected to intensive (Ferreira 2003) or extensive breeding (Flor & Tadich 2008, Silveira et al 2009) and causes significant losses in milk production, which may reach 1.5kg of milk/day (Warnick et al 2001).…”

The purpose of this study was to investigate histological changes in dairy cows' hooves with or without injuries from naturally acquired laminitis. Cull cows with no clinical signs of hoof abnormalities (G1, n=9) and those with macroscopic lesions associated with laminitis without (G2, n=23) or with lameness (G3, n=7) were used in the study. After slaughter, samples of dermo-epidermal junctions of sole, axial and dorsal regions of the hoof were obtained and histologically processed using HE and PAS staining. Congestion, hemorrhage and inflammatory infiltrate in the dermis of sole, axial and dorsal regions were blindly and semiquantitatively evaluated by the same researcher. Inflammatory infiltrate was evaluated in the dermal laminae of axial and dorsal regions. The morphology of epidermal cells and the presence of irregularities in three regions of the basement membrane (BM) length were examined using PAS staining. Scores of lesions in different regions of the hoof in the same group and in different groups for each region of the hoof were compared using non-parametric analyses. Inflammatory infiltrate in the dermis of all regions of the hoof was detected in all groups with no significant statistical difference. Cows with no clinical signs of hoof abnormalities secondary to laminitis (G1) have inflammation scores and epidermal cell changes similar to those of groups with laminitis injuries, suggesting the existence of a prodromal phase for this disease in bovines. BM had irregularities with a variable intensity along its length, however, with no difference among groups. The pattern of BM irregularities found has not been reported so far and does not resemble the BM collapse described in horses and cattle with induced acute laminitis. Is it concluded that even in the absence of macroscopic hoof signs associated to laminitis, dairy cows have histological injuries compatible with inflammation of the dermo-epidermal junction as in affected animals. Basement membrane of cows with or without laminitis associated lesions had irregularities with an irregular distribution along its length which need to be further studied.

Hoof care, lesion curettage, and application of 5 % Stryphnodendron adstringens bark extract (S. adstringens (Mart.) Coville) or 3 % copper sulfate on surgical wounds of cattle were carried out in this research. A total of 180 cattle with digital dermatitis were used. They were distributed into six groups of 30 animals each (GI, GII, GIII, GIV, GV, and GVI). In GI and GII, only the sick digit was trimmed; in GIII and GIV, both sick and healthy digits of the lesioned limb were trimmed; and in GV and GVI, all digits were trimmed. During the postoperative period, 5 % S. adstringens extract was applied in GI, GIII, and GV, and 3 % copper sulfate solution was applied in GII, GIV, and GVI. After 60 days of evaluation, the data were analyzed using the Chi-squared test (p ≤ 0.05). Both therapeutic protocols utilizing surgical curettage of the lesions were efficient for treating digital dermatitis. However, when the procedure is followed by the trimming of sick and healthy digits, the healing is optimized and a greater number of animals are rehabilitated.
