Barriers To Rotational Grazing: Perceptions From Ranchers in the Dakotas

Plan Now to Control Weeds With Grazing Next Season
Livestock will graze Canada goldenrod, Canada thistle and perennial sow thistle. At certain times of the year, these plants have crude protein, total digestible nutrients, and invitro dry matter digestibility concentrations similar to alfalfa and other common forages.

Rotational Grazing During Winter
Winter feed represents one of the largest costs for a livestock production enterprise. Grazing pasture that has been stockpiled for winter use is a rational alternative to limit costs resulting from both harvest and feeding of hay.

Thistle Caterpillars Showing Up on Canada Thistle
