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

 

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: Season 6, Episode 10: Defining Resiliency and the Research Driving Swine Health Forward

Genetic research and new technologies continue to influence the future of swine health and production efficiency. In this episode, we explore how research and technology are being used to support stronger, more resilient pigs, while also improving overall production outcomes. In this episode, we are joined by Dr. Jenelle Dunkelberger, geneticist with Topigs Norsvin, to discuss both routine and emerging strategies for improving piglet, pig, and sow livability. She outlines two primary approaches to enhancing resiliency: gene editing and traditional selective breeding. Continuing the resiliency conversation, we also hear from Dr. Lucina Galina, director of technical research projects at the Pig Improvement Company. She shares insights into ongoing gene-editing work focused on PRRS, detailing the pathway to success, regulatory and practical considerations, and the questions that still remain as the technology evolves. Together, these conversations provide a closer look at how research, genetics and innovation are shaping the future of swine health and livability.
