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: Season 7, Episode 5: Understanding Hog Trailer Contamination and Re-Contamination

Biosecurity and foreign animal disease preparedness extends beyond the farm. This episode looks at the risk of contamination on hog trailers as pigs move from different parts of the state to harvest plants.

Dr. Cesar Corzo, associate professor at the University of Minnesota and leman chair for swine health and productivity, and Lucas Ferreira, research assistant and PhD student at the university, discuss how their trailer research got started, how trailers can be exposed to pathogens and where contamination can occur during the transportation process. They also discuss trailer washing, PPE and opportunities to break the chain of contamination and strengthen transportation biosecurity.
