OK To Graze Cool-Season Winter Pastures In May

New SDSU research shows that in won't hurt future grass production. It may even help.

"A lot of people think they should only graze winter pastures in winter, and in reality, grazing them early in the growing season does not affect production for future growth," says Robin Salverson, South Dakota State University Extension cow/calf field specialist.

A three-year research study conducted at Western South Dakota experiment stations indicates grazing cool season winter pastures in early spring can actually boost production, as clipping stimulates future growth.

"We have healthy root structures which allows for the grass to grow and take in nutrients and allows them to have production later in the growing season," she said.

Salverson advises grazing winter pastures for a short time only in early May, allowing livestock to clip the top third of the grass plant.

"Get them on there and graze it so only the top half of the forage is grazed off and then remove those cows," Salverson says.

Be cautious about grazing later in the spring and summer because it can limit future production.

"If you get too late into the season you are going to impact production later," Salverson says.

To prevent this, Salverson recommends limiting spring utilization to about 25%.
