Digital dermatitis is a disease that causes lameness in cattle. It was first discovered in Italy in 1974 by Cheli and Mortellaro. This disease is caused by a mixture of different bacteria. Anaerobic bacteria, including spirochetes of the genus Treponema, are found in the lesions associated with the infection.
The characteristics of the disease are the sudden onset of fever, stiffness, lameness and nasal and ocular discharges. BEF often causes hypocalcaemia which in turn generates clinical signs such as depression, cessation of rumination, muscle tremors and constipation. [citation needed]
Nasal signs may be prominent, with nasal discharge and stertorous respiration. Some animals also develop foot lesions, beginning with coronitis, with consequent lameness. In sheep, this can lead to knee-walking. In cattle, constant changing of position of the feet gives bluetongue the nickname the dancing disease. [12]
The incubation period for FMD virus has a range between one and 12 days. [12] [13] The disease is characterized by high fever that declines rapidly after two to three days, blisters inside the mouth that lead to excessive secretion of stringy or foamy saliva and to drooling, and blisters on the feet that may rupture and cause lameness.
In cow-hocked horses, the hind hocks are too close together and point toward each other, with the feet too widely apart. It is a fairly common defect, and if the metatarsal bones are vertical, may not always cause lameness. A combination of cow- and sickle-hocks poses a greater risk. [1]
In feedlot cattle, a diet containing a high proportion of cereal grain can lead to primary ruminal tympany. [5] The main signs of bloat in cattle are distension of the left side of the abdomen, dyspnea (difficulty breathing) and severe distress. If gas continues to accumulate, the right side of the abdomen may also become distended, with death ...
General systemic signs include diarrhea, anorexia, and weight loss. Infected animals may develop a jaundiced look which then turns into paleness around the eyes, muzzle, lips, and teats of the cattle. [2] All cattle are susceptible to infection by Anaplasma marginale, but the severity worsens with age increase. Older cattle tend to exhibit the ...
Additionally, nonspecific signs have also been observed which include weight loss, decreased milk production, lameness, ear infections and teeth grinding due to pain. Some animals may show a combination of these signs, while others may only be observed demonstrating one of the many reported.
