Chemical treatment at marking
Preliminary results from a small trial at Mount Barker Research Station indicated that applying a chemical treatment at marking may be beneficial in reducing breech strike incidences. Half of the flock of ewe and wether lambs were left untreated, while half received 4 millilitres (ml) Clik to breech and 4ml Clik to purse of ram lambs. Results are shown in the table below. Although there was a low incidence of flystrike, the results confirm that chemical treatment can aid in the prevention of flystrike in non mulesed sheep.

DPIRD ceased mulesing on its research stations in 2008 and since then has been collecting information regarding the management of non mulesed sheep. For past results please see the on-farm research summaries in the side menu.
