June 23, 2022

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.

  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.

When northern Illinois farmer Dan Sanderson started farming in the 1980s, cover crops weren’t exactly mainstream. Government set-aside programs required planting something like oats, but what stuck with Dan wasn’t the paperwork. It was the difference he noticed in those acres the next year—healthier plants and stronger soils. Decades later, that observation led him down a lifelong road of conservation and soil health improvement. In this episode of IL Corn TV, Dan joins IL Corn board member Shane Gray to talk about his path toward regenerative farming, what he learned at a 2017 Soil Health Academy that changed everything, and why he now treats soil as a living system, not something to manipulate. Dan’s story is one every farmer can relate to—trial and error, lessons learned the hard way, and realizing that “good soil” is about more than yield. 🎥 Watch Part 1 now and catch Part 2 soon, where Dan dives deeper into how he’s reducing inputs, improving soil function, and still keeping his yields strong.
