Winter Lice Control

Seeing cattle rubbing hair off due to lice infestations can be extremely frustrating. Not only are the cattle damaging fences and equipment, there also can be performance losses and health issues not to mention that the cattle are simply not as visibly appealing, which can be very important for seedstock producers or feeders selling backgrounded feeders.

Left: Soil from long-term no-till field, exhibiting good soil aggregation through clumping and smaller pieces of soil. Right: Soil from conventionally managed field that included tillage and crop residue removal. Notice the soil is lighter brown, indicating lower organic matter, and the pieces of soil are in larger chunks with no visible indication of clumping or structure.
