Bovine respiratory disease (BRD) is the most common and economically devastating infectious disease affecting beef cattle in the world. [1] It is a complex, bacterial or viral infection that causes pneumonia in calves which can be fatal. It also affects many other species of feedlot animals like sheep and pigs, but is most prominent in calves. [2]
Dictyocaulus viviparus found in the bronchi of a calf during necropsy (arrow). Parasitic bronchitis, also known as hoose, husk, or verminous bronchitis, [1] is a disease of sheep, cattle, goats, [2] and swine caused by the presence of various species of parasite, commonly known as lungworms, [3] in the bronchial tubes or in the lungs.
Body temperature is regularly higher than in any other cattle disease. Fever from 41 to 42 °C (106 to 108 °F) is common in acute stages. Later on (day 5 to day 10 from the clinical onset), temperature will lower to a normal range (38.0–39.5 °C (100.4–103.1 °F)), but the disease will continue to progress, despite a possible apparent ...
Burning the upper layer of soil to eradicate left-over spores is the best way to stop the spread of blackleg from diseased cattle. Diseased cattle should be isolated. Treatment is generally unrewarding due to the rapid progression of the disease, but penicillin is the drug of choice for treatment. Treatment is only effective in the early stages ...
A more acute form of East Coast fever called corridor disease occurs when buffalo-derived T. parva is transmitted to cattle. [3] Another form, called January disease, only occurs over the winter months in Zimbabwe due to the tick lifecycle. [citation needed] Native cattle are often resistant to the parasite, but not without symptoms. They are ...

Fog fever is a refeeding syndrome in cattle, clinically named acute bovine pulmonary emphysema and edema (ABPEE) and bovine atypical interstitial pneumonia. [1] [2] This veterinary disease in adult cattle follows an abrupt move from feedlot (dried feed indoors) to 'foggage pasture' (fast growing, lush pasture, with high protein levels).
The disease can be controlled by ensuring that calves receive adequate colostrum at birth. Management factors such as separating different age groups, and providing good ventilation and clean bedding also reduce disease incidence. Vaccination of young cattle can reduce the severity and incidence of disease. Multiple doses are required and are ...
