Samples are tested for the presence of gB antibodies and if all the samples are negative then farm obtains IBR free certificate. To maintain the IBR free certification all the animals older than 24 months are tested once a year. Individual blood or milk samples are collected and tested for the presence of gB antibodies. In the case of milk samples they can be pooled up to 50 samples.
