Dairy Leaders of Tomorrow

Purpose

Although many consumers purchase fluid milk in the grocery store, there are numerous other products that are made from milk. What are some products that you can think of?

When a farm produces milk, they typically sell their milk to a cooperative, which is a member-owned organization that is responsible for marketing milk to processing plants. Many processing plants specialize in a certain type of product and pay different prices for milk depending upon what product they are manufacturing. There are 4 classes of milk that you will investigate further.

Finally, the US is very fortunate in that our milk production exceeds our demand. This fact allows the United States to export a large number of dairy products across the globe. Utilizing the US Dairy Export Council’s website, you will gain a sense of where American milk products are shipped.
