For farmers and ranchers

The federal record lists M3 Meats for slaughter of cattle, hogs, and sheep and lamb, both under federal inspection and on a custom-exempt basis for animals the customer already owns. Custom-exempt work returns meat packaged and marked Not for Sale, for the owner's own use. The plant is in the smallest FSIS volume class, under 1,000 head per year, so capacity is limited. Booking lead times, scheduling, kill fees, cut and wrap charges, and minimums are not stated in any source on file. Producers should call (406) 433-3410 to confirm availability and terms.

M3 Meats reports custom-exempt slaughter to FSIS, which means it can process an animal a customer already owns (a whole, half, or share bought before slaughter) and return it in packages marked Not for Sale. Most small farms have one or two plants they book with, and the plant's calendar decides the delivery date.
