Study Monitors Long-Term Impacts Of Feeding GM Crops To Livestock

Sep 29, 2014

Recently, Dr. Alison Van Eenennaam and research assistant Amy E. Young completed the most comprehensive study of genetically modified (GM) crops ever, set to be published in the Journal of Animal Science after Oct. 1.

It represents the longest-term monitoring of the health-impact of GM crops in history as it examines at 29 years of livestock productivity and health data from both before and after the introduction of GM crops into animal feed formulations.

"The broiler information set is the most powerful because we looked at 9 billion birds that were fed mostly GM crops," Van Eenennaam said. "There was improved feed-to-gain ratios and decreased age to market, which suggests that feeding GM crops did not having any detrimental effects to the birds' health."

The U.S. Grains Council uses studies like this one to encourage policymakers around the world to develop biotechnology policies that are science-based, risk-appropriate and consistent. The new findings could have implications for the international marketplace as some countries continue to reject GM crops based on non-science based safety concerns.

Video: How Swine Nutrition Can Revolutionize Biogas Production - Dr. Felipe Hickmann

In this episode of The Swine it Podcast Show Canada, Dr. Felipe Hickmann from Laval University explores how nutritional strategies and manure management impact biogas production in pig farming. He breaks down the science behind anaerobic digestion at low temperatures and explains how dietary adjustments affect methane production and environmental sustainability. Learn how producers can reduce emissions and improve resource efficiency. Listen now on all major platforms!

"Lowering crude protein can reduce nitrogen in manure, but only if animal intake doesn’t compensate by increasing feed consumption."

Meet the guest: Dr. Felipe Hickmann / felipe-hickmann-963853a6 is a PhD research assistant at Laval University, specializing in swine and poultry sustainability. With extensive experience in manure management, nutritional strategies, and precision livestock technologies, he contributes to improving environmental outcomes in animal agriculture.
