Under the hood of a pickup lies an assembly of metal , its details often forgotten – until the motor breaks down . All that ’ s left is a vehicle that can no longer do its job .

When cattle can ’ t access all the minerals they need reproduction rates drop , tissue growth diminishes and illness sets in .

That ’ s why mineral supplementation underpins any cattle operation .

Less obvious ? “ Things like marbling , ribeye area development and muscle fiber type ,” the Iowa State University feedlot nutritionist explained .
