Visited a dairy
herd outside Dunmanway Co Cork where a herd of 90 cows were presented with clinical
symptoms of IBR. However, the farmer
informed me that all tests with swabs, blood, milk etc.showed no evidence of the virus positive in
IBR. However, some of the samples tested
positive for Mycoplasma which can present with the same symptoms as IBR. One should have milk samples routinely tested
to identify the presence or absence of Mycoplasma.
