This week's edition of "Dairy Good Questions" is going to be a quick one..
DGQ 1) What is a mineral tub for?
Answer: Mineral tubs are used to provide supplemental vitamins and minerals to cows that are out on pasture and rely on grazing or hay as their primary diet. These tubs contain trace minerals such as selenium, zinc, and cobalt, and are available in several different formulations depending on the animals' nutritional needs. The tubs we provide for our heifers and dry cows come with the minerals and vitamins suspended in a molasses-based liquid that is poured into a plastic tub and hardens into a block. Cows will spend a few minutes a day licking the mineral tub, seeming to instinctively know both when they need it and when they've had enough.
