Alternate Grazing

By using a "leader and follower" system, the cleanest pasture can be retained for the more susceptible animals and the more contaminated pasture can be grazed by the most resistant stock. These latter animals may also help clean the pasture of infectious larvae.

The "leaders" in the system are normally the younger animals and the followers the older animals. The system can also utilise differences in breed or species susceptibility, with small ruminants grazing ahead of cattle or more resistant genotypes such as red maasai sheep grazing behind more susceptible types.
