Explainer: Avian flu in dairy cows warrants close attention

Farmers should identify unusual signs of disease in cattle and have them examined by a veterinarian

An emerging disease syndrome was originally identified in dairy cows in Texas. These cows were identified by animal care workers and veterinarians as having the main clinical signs of reduced milk production and decreased feed intake. Approximately 10 per cent of the cows seem to show clinical signs on affected farms. No deaths occurred and cows seemed to recover with supportive care within two to three weeks. However, loss of milk production was significant. These same farms reported deceased wild birds on their properties.

BRD is the most common reason for administering antimicrobial drugs to cattle and is probably one of the most important economic diseases of beef cattle in North America.

Microbiome research could help in respiratory disease diagnosis

BRD is more complex than just a single bacterial indicator

The fall calf run will have finished up and calves will now be into feedlots. Many calves travel to feed yards via auction markets and one of the major disease risks associated with the stresses of weaning, mixing and transportation is the syndrome known as bovine respiratory disease (BRD). BRD is the most common reason […] Read more
