Three Nutritional Tools to Help Tackle Heat Stress

Heat stress is about more than keeping cows cool. It also changes how they eat, digest nutrients, and maintain production.

Supporting cows through hot weather starts with a strong nutritional foundation. Tools like yeast, chromium, and betaine can help support rumen function, hydration, and metabolism, making them valuable additions to a broader heat stress management strategy. Nutrition works best alongside proven cooling practices and good cow comfort.

“Heat stress affects more than body temperature. The right nutritional tools can help cows better maintain intake, rumen health, and performance during periods of elevated heat.”

Well-Fed Calves Prefer Play Over Food

Calf behavior can tell us a lot about how nutrition programs are working.

Well-fed calves are more likely to spend time exploring, socializing, and playing instead of focusing on feed-seeking behavior. Those early indicators can offer valuable insight into calf comfort, health, and overall development.

“The key takeaway, I think, is that there are clear benefits in feeding calves more milk and in housing them in bigger pens with peers, so as to favor play behaviors,” Lecorps says.

Beyond the gate: What really drives sorting efficiency?

Sorting efficiency starts well before cattle reach the gate. Effective sorting, from facility design and cattle flow to handling practices and team consistency. Small adjustments in setup and process can lead to safer handling and better overall efficiency.

“Sort gates are a powerful productivity tool. With proper planning, setup and care, they can ease labor demands, improve cow flow and simplify daily routines. But too often, sort gates fall short of their potential when service, strategy or support are treated as afterthoughts.”

Lifespan and healthspan: improved culling

Culling decisions play a major role in both the lifespan and long-term health of a dairy herd, and they are not always as straightforward as they seem. A recent article from Hoard’s Dairyman looks at how rethinking culling strategies can lead to healthier cows that stay productive longer.

The article explains that many cows are removed from herds not solely because of age, but due to preventable health challenges such as lameness, mastitis, or metabolic stress. When these issues are managed earlier and more consistently, cows are better positioned to remain in the herd and perform well across multiple lactations.

It also highlights the difference between lifespan and healthspan. While keeping cows longer is one goal, maintaining their comfort, mobility, and overall well-being throughout that time is just as important. Thoughtful daily management, including nutrition, monitoring, and timely intervention, plays a critical role in reducing involuntary culling.

Winterizing Ventilation Fans in Dairy Barns

Proper ventilation is critical year-round, but winter brings unique challenges for dairy barns. A recent Progressive Dairy article by Sam Leadley, Ph.D., highlights the importance of winterizing ventilation fans to maintain air quality, prevent moisture buildup, and protect herd health through the colder months.

Leadley emphasizes that poor winter airflow can lead to condensation, increased bacterial growth, and respiratory stress in calves and cows alike. Key steps include inspecting fan blades and shutters for dirt or ice buildup, sealing gaps that create drafts, and ensuring inlets are clean and unobstructed.

Balancing air exchange without excessive heat loss is the goal. Proactive maintenance not only improves animal comfort but also extends the life of equipment and supports overall barn efficiency.

Water: The Overlooked Nutrient in Dairy Farming

Water is the most essential nutrient in dairy farming, yet it is often overlooked. A recent DairyHerd article featuring Dr. Vern Osborne emphasizes water’s critical role in cow health, productivity, and facility management. Key areas include water quality, nutrient supplementation through water, facility design, and sustainable practices.

Osborne describes water as the “mega molecule,” essential for every cell function. Transition cows, in particular, benefit from nutrient-enriched water to maintain energy balance during stress. Facility design also matters; strategically placed bowls, troughs, and moving water features stimulate natural drinking behaviors.

Water quality directly impacts intake and herd health. Osborne recommends full chemical analysis of water sources and mechanical filtration methods for consistent, safe quality. Looking ahead, practices like rainwater harvesting and improved filtration will be vital as environmental and economic pressures grow.

Prioritizing water management enhances cow well-being and strengthens long-term farm efficiency.

Beyond the Feed: A Whole-Farm Approach to Dairy Success

At Cornerstone Ag Management, we believe that true dairy performance is about more than just nutrition. It’s about understanding the entire operation. That’s why our team of consultants partners closely with producers to support herd health, forage planning, crop rotations, and long-term efficiency.

A recent article in Tri-State Neighbor highlighted the work of our own Brent Van Middendorp and his integrated role at Hilltop Dairy in Elkton, South Dakota. His work there reflects our broader philosophy: when nutritionists collaborate with the full farm team, herdsmen, vets, calf growers, and feed crews, great things happen.

What does this whole-farm support look like?

  • Customized Nutrition + Forage Strategy: Brent helps Hilltop Dairy make decisions about crop selection, field rotations, and harvest timing, ensuring the feed they grow matches their herd’s nutritional needs and supports soil health.
  • Hands-On Herd Oversight: From walking barns and observing cow behavior to adjusting rations based on forage quality, our visits are about more than numbers; they’re about knowing your herd.
  • Future-Focused Calf Care: Calf performance today impacts the milking herd tomorrow. At Hilltop, calves are raised nearby under attentive care and customized rations designed by Cornerstone, helping achieve a 90% return rate to the milking herd.
  • Efficiency Through Local Sourcing: Brent works with dairies to source ingredients smartly, balancing cost, quality, and proximity to drive long-term sustainability.

As Brent says, “Our milk production today is the result of what we failed or achieved over the last three years.” That’s why every decision matters.

Are you focusing on these cow comfort essentials?

Cow comfort is foundational to dairy productivity. A recent article from AG Proud emphasizes key areas that directly impact cow well-being: ventilation, cooling systems, stall bedding, feed and water facilities, bedding, and lighting. By focusing on these essentials, farms can enhance cow health, increase milk production, and improve overall efficiency.​

Proper ventilation and cooling systems help maintain optimal barn temperatures, reducing heat stress. Comfortable bedding encourages cows to rest more, which is vital for milk yield. Adequate lighting supports natural behaviors and can influence reproductive cycles. Ensuring easy access to feed and clean water promotes consistent intake, supporting digestion and overall health.​

Implementing these cow comfort strategies benefits the animals and contributes to the farm’s profitability.​
