To find the most up-to-date information, I recommend you check these resources:
* Michigan Department of Agriculture and Rural Development (MDARD): Their website often has statistics and reports related to agriculture in the state.
* United States Department of Agriculture (USDA): The USDA's National Agricultural Statistics Service (NASS) collects and publishes agricultural data, including farm numbers.
* Michigan Farm Bureau: This organization represents farmers in the state and may have statistics about dairy farms.
By contacting these organizations directly or checking their websites, you'll find the most accurate and recent information on the number of dairy farms in Michigan.
