Zinc plays vital role in animal and human fertility, can help scientists quickly diagnose infertility

Jun 19, 2018

Infertility affects about 20 percent of the U.S. population and can be incredibly costly; it also costs the livestock industry billions of dollars each year. Researchers at the University of Missouri have found that zinc plays a key role in promoting fertility in males, a discovery that has implications for improved in vitro fertilization and artificial insemination in livestock, and for human infertility diagnostics and therapies.

“Zinc is linked directly with fertility,” said Peter Sutovsky, a professor of animal science in MU’s College of Agriculture, Food and Natural Resources. “We have known that giving males zinc supplements—whether pigs or humans—improves fertility. Now we know that analyzing zinc signatures can help us quickly evaluate the fertilizing potential and quality of sperm.”

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.
