Any existing herd health problems are amplified by HPAI H5N1, practitioners report. Across the U.S., they are asking regulatory agencies for more consistent testing and reporting protocols. They are also encouraging producers to invest dollars in better nutrition and cow comfort resources.
An Update on Bird Flu in Cows
Nearly 71% of all dairy herds in California have caught the illness since August.
What we know – and don't know – about avian flu
Why the results surprised anyone is itself a surprise. After the state of California began testing dairy herds for highly pathogenic avian influenza, known also as bird flu or H5N1, in August, it found the pathogen on 645 dairy farms.

The FDA announced Monday it has begun collecting samples of aged raw cow's milk cheese to test for bird flu as the U.S. battles an outbreak of the virus.
A single mutation in dairy cow-associated H5N1 viruses increases receptor binding breadth - PubMed
Clade 2.3.4.4b H5N1 is causing an unprecedented outbreak in dairy cows in the United States. To understand if recent H5N1 viruses are changing their receptor use, we screened recombinant hemagglutinin (HA) from historical and recent 2.3.4.4b H5N1 viruses for binding to distinct glycans bearing termi …

H5N1 Detected in Dairy Cattle for the First Time
No. 5 on DTN's list of the Top 10 Ag Stories of the Year focuses on how dairy cattle have been affected by the H5N1 strain of avian influenza. Unlike the depopulations of poultry with a detection of highly pathogenic avian influenza at a facility, a dairy cow testing positive for H5N1 leads to a decrease in milk production and flu-like symptoms, which most recover from over time.
Tracking bird flu virus changes in cows is stymied by missing data, scientists say
Scientists are frustrated that the USDA again failed to include basic information about H5N1 genetic sequences from cows when the data were released this week.
