The Spread Of Avian Flu Continues In Poultry Farms

It was confirmed on Friday at a non-commercial poultry operation in Lacombe County. It's unclear how many birds there were infected with the H5N1 strain. Recently, there were four additional cases of avian flu in 3 commercial poultry flocks in Quebec and one in Ontario. The CFIA didn't release any information about what types of flocks were involved or how many birds were in those flocks. It's very likely all of the birds that didn't die from the disease would have to be destroyed.

It's widely believed the disease is spread to domestic flocks by migratory birds which are now returning to Canada. Industry officials are concerned that as more migratory birds make their way north, more cases of avian flu will be reported. BC has been the hardest hit over the past year, followed by Alberta.

Video: Dr. Jay Johnson: Bioenergetics of Heat Stress in Sows

The Swine Health Blackbelt Podcast, Dr. Jay Johnson from the University of Missouri explores the bioenergetics of heat stress in gestating sows and how it affects growth and fat deposition. He discusses energy partitioning, thermoregulation, and genetic strategies to improve thermal tolerance without compromising productivity. Listen now on all major platforms!

"Gestating sows under heat stress grow faster than those in thermoneutral conditions, with much of that growth going into backfat."

Meet the guest: Dr. Jay Johnson earned his Ph.D. from Iowa State University and is now an Associate Professor of Animal Welfare and Stress Physiology at the University of Missouri. His research focuses on heat stress, swine productivity, and practical welfare innovations through physiology and genomics.
