Heat Stress Kills Estimated 10,000 Head of Kansas Feedlot Cattle

 

 

Would more shade have helped prevent US feedlot deaths?

THE deaths of more than 10,000 feedlot cattle in the United States have been drawing plenty of attention in the past week, with graphic pictures emerging online and debate raging about the cause of the incident.

 

While there were some wild theories about how it happened, evidence is pointing to heat stress – with the perfect storm of hot, humid, still weather and not much relief at night.

 

One of the most noticeable parts of the Kansas feedlot pictures was a large absence of shade, a complicated issue in the US.

 

While the Australian lot feeding industry has had a major focus on it in recent years, with the peak body aiming to have all its members providing shade by 2026, University of Queensland professor John Gaughan said the situation was different in US

 

“They have snow over there and snow puts an extreme loading on top of the shade structures,” Dr Gaughan said.

 

“There’s an extra workload in taking shade structures down in the winter and putting them back up in the summer. But it is a welfare issue and there is productivity benefits from having shade.

 

“Shade would not have stopped all cattle dying in Kansas, but I do believe shade would have reduced the death rates in the US – at least that is what our previous experience shows us.”

 

Dr Gaughan said with the extreme conditions faced in the US last week, deaths would have been hard to prevent. He said pens can easily become muddy in the US climate.

 

“Cattle were coming out of winter, they were in good body condition and still had their winter coats on and the pens would have been wet and muddy,” he said.

 

“With our research we have learnt a lot about the duration of heat stress events. One-or-two days of bad conditions isn’t a problem, but five days is.”

Thousands of Cattle Reported Dead

Heat Stress Kills Estimated 10,000 Head of Kansas Feedlot Cattle

A heat wave that blazed through Kansas feedlots early last week killed an estimated 10,000 head of fat cattle.

 

Final death numbers continue to come in, but that early estimate was shared with DTN by livestock experts, who put the geographical center point for those deaths at Ulysses, Kansas.

 

DTN calls to feedlots in the area and to ranchers whose branded animals were seen in some privately shared photos of dead cattle were not returned.

 

What is known is that leading up to these heartbreaking losses, temperatures in the area were over 100 degrees Fahrenheit, there was humidity, and there was little to no wind to help cool the animals. Temperature readings reported for Ulysses began to exceed the 100-degree mark on June 11. By June 13, the high temperature was reported at 104 degrees, with humidity levels ranging from 18% to 35%. Temperature and humidity levels began to break some on June 14. Just a few days prior to the heat setting in, highs had been in the 80s.

 

Corbitt Wall, a cattle analyst with National Beef Wire who works out of Amarillo, Texas, told DTN he heard from two non-media sources about the extent of the Kansas losses. He noted there was frustration that despite such extensive losses, the futures market fell last Monday.

 

"I know it's hard for people in the business to watch that futures market, but it's not real," he said. "The only time those traders and speculators make money on futures is when the market is volatile, and they are watching these algorithms to tell them where the market is going. For people following the fundamentals, it is frustrating."
