Benefits & Challenges of Switchgrass
Switch grass is appealing as an alternative bedding source because it thrives in marginal soils. Switchgrass also poses a noticeable challenge, however, being difficult to grind to the right particle size for animal bedding.
Grinding Switchgrass for Poultry Bedding
“With tub grinders and other type of grinder instruments, we get a lot more of the rogue or longer pieces.”
Brown notes that the ideal animal bedding material is absorbent and uniform in size. If bedding contains oversized pieces, these larger fibers collect at the top of the bedding, while the smaller particles sink to the bottom. The oversized pieces then mat down and form a crust, which prevents air flow and absorption. Essentially, a top layer of crust formed by oversized pieces renders most of the bedding useless. “With tub grinders and other type of grinder instruments, we get a lot more of the rogue or longer pieces,” Brown states.Brown and fellow researchers are excited about the potential of switchgrass to help fill the need for non-traditional bedding materials. “We are in need of a sustainable, renewable and reliable bedding source” says Brown. “Many traditional sources of bedding are no longer available.”

This field trial involves just one alternative bedding source currently in use or commercial testing. The need for animal bedding is already driving the demand for animal bedding made by processing wood waste with industrial grinding equipment.To learn more about this field study, check out the original article.To learn how Rotochopper grinders convert diverse feedstocks into animal bedding, contact your regional Rotochopper representative.
