Abstract:
The dairy cow is an amazing creature. She produces fresh, wholesome milk that is made into lots of different dairy products. She is a ruminant, meaning that she has a four-compartment stomach. Her four stomach compartments allow her to eat feeds that humans cannot eat like grass and hay. She is also able to make milk from by-product feeds, materials leftover after making other products. For example, whole cottonseeds are left over after removing cotton to make cloth. Whole cottonseed is a great feed for the cow because it is high in fiber, energy, and protein. Bakery waste (bread, pastries, donuts), citrus pulp (orange juice), corn hominy feed (flour) are a few examples of other by-product feeds that cows like to eat. Participants will get to identify and handle many of the feeds that the dairy cow eats.
