rBST: The End of an Era

By Jim Dickrell 
 
 
By the end of this year, very few dairy processors will accept milk produced with rBST. There will still be a few pockets here and there in the Midwest and possibly in Idaho, but for the most part, rBST will fade into history—driven there by ignorance, misinformation and fear.
 
Part of the blame falls to the dairy industry itself. Proponents tried to explain but could never completely convince naysayers about the benefits of the technology and how it could provide more dairy products at lower cost without jeopardizing food safety or cow health. Opponents, both within and outside the industry, played on consumer fears of “Franken foods” and, worse, what it might do to children’s growth and development. The most recent example came just last month when Arla Foods USA launched a 30-second ad targeted toward grade school kids.
 
 
Prior to its launch in 1994, rBST opponents within the industry feared a flood of milk and crashing milk prices as a result. That never happened, with adoption rates probably never reaching a fourth of farms.
 
Take a look at the chart below, supplied by Brian Gould, an dairy economist with the University of Wisconsin. Milk per cow, the blue line, has grown at a pretty steady 2.2% compound annual growth rate since the end of World War II. Can you tell when rBST was introduced? Even if you draw a vertical line up from 1994 when rBST was introduced, the slope of the graph doesn’t change. And the decline in cow numbers, the red line, actually tapered off in the mid-90s, when rBST use was likely at its highest rate.
 
But the opposition to rBST, based on that fear, helped create the environment of consumer paranoia of food technology we now find ourselves in. It’s an ugly place between a rock and hard place to be.
 
In and of itself, the loss of rBST isn’t that big of a deal. Dairy farmers in the Northeast who lost the technology first learned to live without it, and within a year or two, are producing just as much milk per cow as before.

Dr. David Rosero: Fat Quality in Swine Diets

Video: Dr. David Rosero: Fat Quality in Swine Diets

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. David Rosero from Iowa State University explores the critical aspects of fat quality and oxidation in swine diets. He discusses how different types of lipids affect pig performance and provides actionable insights on managing lipid oxidation in feed mills. Don’t miss this episode—available on all major platforms.

Highlight quote: "Increasing levels of oxidized fats in swine diets reduced the efficiency of feed utilization, increased mortality, and led to more pigs being classified as culls, reducing the number of full-value pigs entering the finishing barns."

Meet the guest: Dr. David Rosero / davidrosero is an assistant professor of animal science at Iowa State University. His research program focuses on conducting applied research on swine nutrition and the practical application of smart farming. He previously served as the technical officer for The Hanor Company, overseeing nutrition, research, and innovation efforts.
