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.”

Many Canadian grazing recommendations were developed using beef cattle in the prairies. While we have adapted these the forage species and climate in Ontario, other livestock have different needs. Public enemy number one for grazing sheep are gastrointestinal parasites.

The purpose of the Profitable Pasture conference is to bring fresh ideas and new research results to Ontario grazing managers across the ruminant livestock sectors. These conferences have a major focus on pasture management.
