When the people from the drug company came out to visit Tyler Karney at Ordway Feedyard on Colorado’s eastern plains, he was a little skeptical.
They said their product, Zilmax, could put another 30 pounds on an animal in the last days before slaughter. Then he started blending it into the feed for the 6,500 head of Holsteins at this huge feedlot.
“We feed it the last 20 days of the feeding period and when you drive by, you can actually see a physical change in the animal,” Karney said. “They’re chest floor’s wider and just, a boxier animal. It’s kinda hard to believe.”
