What’s in it
BACKGROUND —— GENERAL. Confinement feeding operations are regulated by the department of natural resources (DNR) under the “Animal Agriculture Compliance Act” (Code chapter 459). A confinement feeding operation is a type of animal feeding operation in which agricultural animals are maintained for at least days in any 12-month period.102).311). Regulations governing confinement feeding operations vary based on the size of the operation measured by its animal unit capacity (AUC). AUC refers to a measurement used to determine the maximum number of animal units that may be maintained as part of a confinement feeding operation at any one time.
