Mulesing (also known as 'live lamb cutting') is the removal of strips of wool-bearing skin from around the breech of a sheep to prevent the parasitic infection flystrike . [1] The wool around the buttocks can retain feces and urine, which attracts flies.

[8] Occasionally the infection can be extensive and persistent if the animal does not produce an immune response. [1] A sheep with orf infection on nose and lips
In ewes, urine can also stain the wool. To avoid discomfort to the sheep and damage to the fleece, graziers remove the wool (and any dags) from the sheep. Urine and watery faeces from eating spring grass can also lead to myiasis (fly-strike), which occurs when flies lay eggs in warm, damp wool and the fly larvae grow and eat into the sheep ...
Flystrike in sheep is a myiasis condition in which domestic sheep are infected by one of several species of flies that are external parasites of sheep. Sheep are particularly susceptible to flystrike because their thick wool, if sufficiently contaminated with urine and faecal material, can provide effective breeding ground for maggots even in the relative absence of wounds.
In addition, shearing the ewe before lambing can increase the quality of the fleece as wool breaking can occur since giving birth is such a major stress on the ewe's body. [36] It is important to keep in mind weather conditions prior to shearing ewes, especially in colder climates. [37]
