abstract

an outbreak of a lethal disease was reported in 4–6-month-old holstein calves in a feedlot around tehran. the signs of central nervous system and gastrointestinal system (gi) involvement were observed in the diseased animals. necropsy samples of gi, liver, kidney, spleen and lung from 3 died animals were prepared for histopathological examination. blood and formalin-fixed ear notch samples of 6 calves were submitted for rt-pcr, antigen-capture elisa (ace) and immunohistochemistry (ihc) for the detection of bvdv. the results of ace on buffy coats were negative but rt-pcr of all 6 cases and ihc of 4 cases were positive for bvdv infection. based on the clinical signs and pathological findings in the gi system and brain, we strongly suggest that the bvdv may represent a gastro-neuropathogen strain. to the best of our knowledge, this is the first outbreak of gastro-neuropathogenic bvdv infection in iran, which may be acquired postnatally.

Preparing Calves for the Feedlot

Evidence based medicine is a balancing act between data and experience (Apley and Thomson, 2003). Decision making with just experience and no data has been termed “wizardry.” This would be similar as to saying we used drug A last year and they all died. This year we used drug B and they all lived. Great! Scientists and statisticians need not apply to work in this environment. The friendly drug ...
