Novel Vaccination Approach Enhances Worker Safety

Sep 30, 2019

A novel approach to vaccinating sows, gilts and their piglets offers a new method of preventing disease that is safer for barn workers. Researchers with VIDO-InterVac are exploring the effectiveness of administering vaccine directly into the uterus of the pig during artificial insemination.

Dr. Heather Wilson, a research scientist with the Vaccine and Infectious Disease Organization at the University of Saskatchewan, says, because most of the important swine diseases impact reproduction or newborn piglets, the idea was to develop a vaccine to target the uterus to immunize the mom, who could then deliver passive immunity to her babies through her colostrum.

Clip-Dr. Heather Wilson-Vaccine and Infectious Disease Organization:

What we're hoping is that we can show that, instead of giving a needle vaccine to sows or gilts, they're very strong animals, they're kind of dangerous and any time we can remove a needle, it's a good thing for the safety for the barn personnel. If we can show administering a vaccine during artificial insemination, delivering it to the uterus, gives a very good immune response.

We can show people how safe it is, then we would hope to communicate that to the veterinarians, to the pig barns and maybe change the whole way that vaccination takes place for reproductive infectious diseases. Initially we are targeting the pig industry but we would like to look at any other animals that use AI.

Video: What Does 20 MILLION Hogs a Year Look Like?

?? The Multi-Plant System Processing 20 Million Hogs Annually in the Midwest JBS USA operates multiple large-scale pork processing facilities across the Midwest, including major plants in Iowa, Minnesota, and Indiana. Combined, these facilities have the capacity to process approximately 20 million hogs annually.

Each plant operates high-speed automated slaughter systems capable of processing up to 20,000 head per day, followed by fabrication lines that break carcasses into primals, sub-primals, and case-ready retail products.

Hog procurement is coordinated through electronic marketing platforms that connect regional contract finishing operations and independent producers to plant demand schedules. This digital procurement system allows for steady supply flow and scheduling efficiency across multiple facilities.

Processing plants incorporate comprehensive food safety systems, including pathogen intervention technologies, rapid chilling processes, and integrated cold-chain management. USDA inspection is embedded throughout the harvest and fabrication stages to ensure regulatory compliance and product integrity. Finished pork products — from bulk primals to retail-ready packaged cuts — are distributed through coordinated logistics networks serving domestic and export markets.
