Preg-Checking in a Drought Year with High Cull Cow Prices

In the dynamic world of cattle production, producers constantly face challenges that test their resilience. One such challenge for many beef producers this year is drought and higher feed costs. When water becomes scarce, pastures are stressed and the costs of maintaining a herd can surge.  

In drought conditions, every mouth to feed counts. Producers may be forced to reduce their herd size to sustain the remaining animals. In such situations, making well-informed decisions is critical for the economic viability of an operation. By preg-checking and identifying open cows, producers can choose to cull those open cows early, reduce the herd’s overall feed requirements and minimize additional costs associated with keeping the open animals.

Genetics vs Genomics in Swine - Dr. Max Rothschild

Video: Genetics vs Genomics in Swine - Dr. Max Rothschild



In this episode of The Swine it Podcast Show Canada, Dr. Max Rothschild, Distinguished Professor at Iowa State University, explains how genetics and genomics have transformed swine production. He explores genomic selection, key gene discoveries, and the role of gene editing in improving disease resistance and productivity. Practical insights on litter size, meat quality, and industry adoption are also discussed. Listen now on all major platforms!

"Genetic improvement in swine production accelerated significantly once molecular tools enabled identification of DNA level variation influencing growth, reproduction, and meat quality across commercial populations."

Meet the guest: Dr. Max Rothschild / max-f-rothschild-b3800312 earned his PhD in Animal Breeding from Cornell University and has spent over four decades at Iowa State University advancing swine genetics and genomics. His research focuses on genetic improvement, disease resistance, and molecular tools for swine production. A leader in pig genome research, his work has shaped modern breeding strategies.
