Rude Awakening for Crops, Livestock as Plains See Temperature Swing

Rude Awakening for Crops, Livestock as Plains See Temperature Swing
By Pam Knox
 
It may seem unlikely, but a pair of typhoons in the Western Pacific may have contributed to the blast of cold air that is moving through the central US, according to an article this week in AgFax. According to the article, the typhoons helped build up a strong ridge of high pressure in the western US, which is contributing to the forest fires there. Downstream, in the central US, a large trough of low pressure is associated with the unseasonably cold air, which is bringing snow to the Front Range of the Rockies. Livestock are having a hard time acclimatizing to the rapid change from temperatures near 100 F to below freezing in just two days, and producers are worried about how they will handle the cold weather so early in the season. Fortunately, the cold outbreak is not expected to last long. You can read more here.

Video: Heat Stress in Pigs: What to Prepare for Before Next Summer - Dr. Joshua Selsby

In this episode of The Swine it Podcast Show Canada, Dr. Joshua Selsby from Iowa State University explains how heat stress affects swine biology and why now is the ideal time to prepare for next summer’s challenges. He breaks down its effects on muscle function, immune responses, and long-term metabolic outcomes. Learn how early planning can protect herd performance when temperatures rise again. Listen now on all major platforms! "Heat stress leads to a cascade of biological damage, beginning with metabolic disruption and expanding across multiple organ systems." Meet the guest: Dr. Joshua Selsby is a Professor in the Department of Animal Science at Iowa State University. With over 15 years of research on skeletal muscle physiology and heat stress, he focuses on understanding how thermal stress disrupts swine metabolism, immune function, and muscle integrity.
