Feeding changes open opportunities

There’s a strong relationship between health and growth in a calf’s early life and that animal’s lifetime production. That means what happens to a calf in its first few hours and days is extremely critical, particularly concerning what it’s fed.

What, how much and when to feed calves is changing and opens new opportunities for producers to impact the long-term health, growth and productivity of their animals, said Michael Steele, a professor in the University of Guelph-Department of Animal Biosciences.

“You can mold the calf when it’s born,” he said. “We call this developmental plasticity, which is strong early in life and goes down as time goes on.”

Video: Post-Weaning E. coli Control - Dr. Rodrigo Paiva


In this episode of The Swine it Podcast Show Canada, Dr. Rodrigo Paiva, DVM and PhD candidate at Iowa State University, explains how post weaning colibacillosis has changed in recent years and why pathogenic Escherichia coli has become more important in swine production. He discusses virulence factors, diagnosis, whole genome sequencing, biosecurity, and practical strategies to reduce disease risk while improving herd health. Listen now on all major platforms!

"Pathogenic E. coli now behaves like a robust, well-equipped truck carrying multiple tools for post-weaning disease."

Meet the guest: Dr. Rodrigo Paiva / rodrigo-paiva-09364355 is a veterinarian and PhD candidate at Iowa State University specializing in swine health, veterinary epidemiology, and post weaning colibacillosis. After several years working in commercial swine production in Brazil, his research has focused on understanding pathogenic Escherichia coli and improving disease prevention in modern production systems.
