When breeding a sheep that is producing a high amount of wool most farmers will shear the hind end of the ewe (called crutching), just enough for the vulva opening to be easily accessed.
Sheep are shorn annually, so it depends of the time of joining and shearing as to how much wool the sheep will actually have in that area. Also farmers are breeding sheep to have less wool in the breech area so that there is a lower risk of fly strike.
Merino
The Merino sheep is a breed originally from Spain and is known for producing fine, silky wool. Merino wool is highly prized for its softness, warmth, and ability to breathe and regulate body temperature.
Marino wool comes from a breed of sheep -- Marino. You can read more about them, below.
Some different kinds of sheep include Merino, Dorset, and Suffolk. Merino sheep are known for their fine wool, Dorset sheep are valued for their meat, and Suffolk sheep are popular for their muscle development and growth rate.

Farmers in South West England have a breed of sheep that loose their wool automatically in the spring, this breed is called the Exlana.
It depends on the type of 'Sheep Herder' that you're talking about. There are certain farms that raise only meat breed sheep. Those 'Herders' would kill there sheep for meat. There are also Wool breed sheep which don't need to be killed because they are raised for there wool and you want them alive so that their wool will grow.
