I have workers who know cattle and sheep. They know how to brand, they know how to feed, they know how to castrate, they know how to break in, they know how to inseminate, they know how to give injections, they know how to milk, they know how to examine. And for sheep, they know how to feed the young, they know how to milk, they know how to herd, they know how to shear, they know how to give birth. 7 years of experience. For cattle, they are doctors, and for sheep, they are also doctors.
