Michigan Compiled Laws, Chapter 287. Animal Industry § 287.127a

Sec. 7a. (1) A licensee shall not transport nonambulatory livestock to a livestock auction, collection point, or buying station. Livestock that become nonambulatory in transport, or while present at a livestock auction, collection point, or buying station shall be humanely euthanized, and the dead animal disposed of as required in subsection (4) or be humanely moved or physically separated from other livestock.

(2) A licensee shall ensure that nonambulatory livestock are not dragged, pulled, pushed, rolled, or otherwise moved except as passive passengers on or in slings, mats, floats, carts, pallets, or containers, or as directly necessary to facilitate the use of these devices. When moved by these devices, the motive force shall be attached to the device, not the livestock. Nonambulatory animals that are not immediately euthanized shall be managed as provided in this section and shall receive appropriate veterinary care.

(3) The director may require a licensee to adhere to specific methods of euthanasia to ensure the welfare of the animal during the euthanasia process.

(4) A licensee shall dispose of any dead animals as defined in 1982 PA 239, MCL 287.651 to 287.683, in the manner required in that act.
