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: World Pork Expo: Tackling oxidative stress at critical stages in swine production

Dr. Marlin Hoogland, veterinarian and Director of Innovation and Research at Feedworks, speaks to The Pig Site's Sarah Mikesell just after World Pork Expo about how metabolic imbalance – especially during weaning, late gestation and disease outbreaks – can quietly undermine animal health and farm profitability.

In swine production, oxidative stress may be an invisible challenge, but its effects are far from subtle. From decreased feed efficiency to suppressed growth rates, it quietly chips away at productivity.

Dr. Hoogland says producers and veterinarians alike should be on alert for this metabolic imbalance, especially during the most physiologically demanding times in a pig’s life.
