Dairy Vocabulary: TMR, Rumen, Cud
Growing up on a dairy farm, there are many words that I hear and use every day that you’ve probably never heard of. I thought it would be fun to share some of these words with you, and tell you what they mean.
TMR — This stands for Total Mixed Ration, which is the name we use for what we feed our cows. It is a combination of different kinds of grass, corn and grain that is mixed by a special machine. Different farms use different mixes of feed as farmers and nutritionists work hard to come up with a mix that is best for their cows. Our cows are fed a mix of corn silage, hay silage, grain (corn), distillers grains, and soybean meal.
Rumen — The rumen is the first and largest part of a cow’s stomach (they have four parts to their stomach). This is the part that breaks down the complex plants they are fed.
Cud — Cud is partially digested food from the rumen that cows burp back into their mouths to chew again. When you see a cow that looks like she is chomping on bubble gum, really she is chewing her cud. Cows can spend 10 hours a day chewing their cud!
