State Orders Increased Bird Flu Biosecurity Measures for Poultry, Dairy Cattle Facilities

By Tracy Samilton

State orders facilities to ramp up biosecurity procedures, after Highly Pathogenic Avian Influenza (HPAI) recently infected dairy cattle in four Michigan counties. It has also infected poultry in 23 Michigan counties since the outbreak began in February, 2022.

Michigan is ordering poultry and dairy cattle facilities to ramp up biosecurity due to a bird flu outbreak.

That's after the bird flu was detected in dairy cattle in four counties last month. Bird flu has infected poultry in 23 Michigan counties since the outbreak began in February 2022.

Highly Pathogenic Avian Influenza A (H5N1), a strain of what is often referred to as bird flu, is responsible for a worldwide outbreak in poultry and wild birds. The current outbreak is the worst in United States history: More than 60 million birds have either died as a result of bird flu virus infection or have been culled due to exposure to infected birds, according to the National Emerging Special Pathogens Training & Education Center.

Among other steps in the state's order, the facilities must appoint a biosecurity manager, limit access points, keep a log of all visitors, and have disinfection procedures for vehicles and people. There are also new restrictions on exhibitions of lactating cattle and poultry.

Tim Boring, Michigan Department of Agriculture and Rural Development director, said the order is among the strictest in the nation.

David Rosero, PhD, assistant professor of animal science at Iowa State University, and R. Dean Boyd, PhD, consultant with Animal Nutrition Research, recently spoke at the Iowa Swine Day Pre-Conference Symposium, titled Soybean 360º: Expanding our horizons through discoveries and field-proven feeding strategies for improving pork production. The event was sponsored by Iowa State University and U.S. Soy.

Every pig producer, nutritionist and veterinarian is familiar with the summer dip. Pig weight loss hits right as market prices are typically rising in July and August, creating a double-hit financially. New nutrition studies conducted on-farm have led leading nutritionists to a solution that includes higher soybean meal inclusion rates in the summer diet.
