How much Floor Space does a Pregnant Sow need in a Group-Housing System with Electronic Sow Feeders?

Yuzhi Li, Associate Professor

Determining floor space allowance for gestating sows can be controversial because more floor space for the sow means less output (profitability) per square foot for the producer. On the other hand, less floor space can compromise sow welfare and performance. In a recent project, we set-out to determine the minimal floor space required for gestating sows. Read more.

Bioaerosol Sampling for Airborne Virus Surveillance in Swine Facilities

Reprinted as posted on UMN Swine Disease Eradication Center's Swine in Minnesota blog.

Bioaerosol sampling refers to the methods by which one is able to collect the particles of biological origin (microbial, animal, or plant) in the air. This is useful information in swine production because many economically important pathogens can be transmitted by air from one farm to the next. Seventy-three scientific reports were included in this review published in the journal Frontiers in Veterinary Science. The information regarding the presence of viruses in the air around swine settings is limited but their findings has been compiled in the figure below. Overall, bioaerosol sampling could be a promising way to conduct non-invasive viral surveillance among swine farms. Continue reading.
