PPE has also been made available to Oklahoma dairy farmers.”Some clinical signs of HPAI in dairy cattle are:• A drop in rumination• A decline in feed intake• A decrease in milk yield• Thicker, concentrated, colostrumlike milk• Lethargy• Dehydration• Fever If dairy farmers suspect cases of HPAI, please call ODAFF at 405-522-6141.For more information on HPAI in dairy cattle, including recommended biosecurity measures, please visit the ODAFF Disease Alerts page.
