Dairy farmers are some of the hardest working people in our country. Tirelessly dedicating each long day to their cattle and to producing milk for consumers. Now is an even more important time to thank these farmers for what they do as June is National Dairy Month! Below is a list of 10 fun facts about the dairy industry, dairy cattle, and IL dairy farms. 

  1. The IL dairy industry contributed around $29.14 billion in economic impact in 2021 
  2. Top 5 counties for number of dairy cows in Illinois (as Jan 1, 2022): 
  • Clinton – 11,800 
  • Stephenson – 10,600 
  • Washington – 6,400 
  • Jo Daviess – 4,100 
  • McLean – 4,000 

3. Dairy foods across the country contribute 3.5% of the U.S. gross domestic product 

4. As of 2019, the U.S. is producing 60% more milk from 30% fewer cows than 50 years ago, in other words, each cow is producing over 2.5 times as much milk 

5. The U.S. dairy industry has decreased water use by 65+% over the past decades. 

6. A lactating dairy cow consumers 30-50 gallons of water a day, along with 110-120 pounds of wet feed or 50-55 pounds of dry matter. 

7. IL dairies led to 117,100 jobs in 2021

8. Dairy cattle have a visual field of almost 360° but have trouble seeing things from head on. Also, dairy cattle cannot see the color red as they lack the red retina receptor. 

9. The greatest amount of milk produced by a dairy cow in the U.S. in one year was 59,298 pounds by a Holstein names Robthom Sue Paddy. To put this in perspective lactating cows produce an average of 23,948 pounds every year. 

10. 94% of dairy farms in the U.S. are family owned and operated

How much do you know about the farmers who came before you and the decisions that still shape Illinois agriculture today? That's what University of Illinois student Lyndon Shi set out to explore during his internship with IL Corn . What began as an archival research project became a deeper look at the history of farmer leadership, innovation and advocacy in Illinois. While digging through university archives, Lyndon uncovered an undigitized manuscript from agricultural economist Harold Guither explaining the case for checkoffs. When he mentioned the discovery to IL Corn Director Rod Weinzierl, he got an unexpected response: "Oh yeah, I know him. We worked with him." It was a reminder that agricultural history isn't as distant as it may seem. Lyndon's research connected two eras of the IL Corn Growers Association: the original organization founded in the 1890s and the modern ICGA established in the 1970s. He learned how University of Illinois agriculture dean Eugene Davenport helped organize corn growers and sent professors across the state on "Corn Gospel Trains" to share the latest farming research. One story stood out in particular: the adoption of hybrid corn. Farmers who once judged corn by the appearance of the ear had to shift their focus to yield. Lyndon sees a similar transition today, as farmers increasingly balance yield with profitability amid rising input costs. "Illinois corn farmers are very good at organizing, and they are genuinely very grassroots," Lyndon said. "They've had a much more active role in shaping policy rather than just being on the receiving end." This Summer and Fall, Lyndon will travel to Taiwan on a federal scholarship to study food security. He'll do so with a new appreciation for Illinois agriculture's global connections, including Taiwan's longstanding role as an important trading partner. Watch the full conversation on IL Corn TV to hear Lyndon's research firsthand and discover how Illinois corn's history continues to influence the future.
