What does milter mean?
A milter is principally a device, person, or animal associated with milking livestock. Its uses include a milking machine, someone employed to milk animals, and a cow or other animal kept for milk. In North American farming vocabulary, “milter” can also mean a male sheep, particularly one retained for breeding. The word sounds old-fashioned and technical, so modern speakers often choose the clearer term “milking machine” when referring to the equipment or “milker” when referring to a person or milk-producing animal. Although its individual senses are uncommon, “milter” preserves a useful distinction in agricultural language between the worker, the animal being milked, the apparatus, and the breeding male. It is therefore most likely to appear in livestock-management, dairy-farming, or historical agricultural contexts rather than in everyday conversation.
A person, animal, or device used for milking livestock.
"The farmer tested the new milter before installing it in the dairy."
The sense is uncommon outside agricultural and dairy contexts; “milking machine” is often the more explicit modern term for the device.
A male sheep, especially one kept for breeding.
"The farmer selected the strongest milter to sire the next flock."
This sense is chiefly associated with North American agricultural usage.
The plural is used for multiple people, animals, or milking devices, as well as for a group of breeding male sheep.
"The automatic milkers ran while the farmhands completed their morning checks."
A “milter” can describe both a milking machine and a breeding ram—two meanings connected by the long history of livestock breeding.

Where does milter come from?
The word comes through Middle English from the root shared with “milk,” with the suffix “-er” traditionally indicating an agent, instrument, or person who performs an action. The related “milch,” now largely literary or regional, likewise refers to an animal kept for its milk. The separate sense for a breeding male sheep developed from agricultural usage and reflects the older English verb “to milt,” meaning to emit sperm.
