Currently this herd is on a six monthly program with HIPRABOVIS® IBR Marker Live protocol for the prevention of IBR, with a double primo-vaccination in the young heifer calves at 3 months of age and booster vaccinations in the adults every 6 months. The farm IBR status is regularly monitored by bulk milk tank sampling every 6 months and every 12 months by the sampling and IBR gE serology of 12-24 months old heifers. The bulk milk tank samples still being positive as it is expected due to the consequential new seropositive animals arisen owning to the outbreak. Regarding the blood sampling, 50% of these animals sampled came back IBR positive six months after the outbreak as a consequence of its infection during this period, when they were younger calves, but no new young heifers appeared positive afterwards. No more clinical cases of IBR have been detected and the epidemiologic situation of IBR is now under control.
