Comparison To Crutching
Mulesing is different from crutching. Crutching is the mechanical removal of wool around the tail, anus (and vulva in ewes) in breeds of sheep with woolly points where this is necessary. Mulesing is the removal of skin to provide permanent resistance to breech strike in Merino sheep. Other breeds tend to have less loose skin, and wool, so close to the tail and may have less dense wool.
Crutching has to be repeated at regular intervals as the wool grows continuously. Frequent crutching of Merinos reduces the incidence of flystrike, but not as much as mulesing.
At the time mulesing was invented, crutching was done with blade shears. In Australia, these have been almost universally replaced with machine shears. Hand shears were being used when Mules inadvertently carried out the procedure during crutching. Mulesing would not inadvertently occur using modern machine shears.
