Study: Unique corn silage delivers significant feed efficiency gain in dairy cattle

DOWNERS GROVE, Ill., USA, Dec. 5, 2019 – Providing a crucial benefit for dairy producers in a challenging economy, Enogen® Feed corn silage delivers significantly higher feed efficiency than conventional corn silage, according to newly released results from a leading university feeding trial. The study found a 4% ECM feed efficiency gain (6% uncorrected) with Enogen Feed hybrids, available from Golden Harvest® Seed Advisors in select geographies.

“This study confirms what dairy producers who grow it for their operations already know: that a simple switch to Enogen Feed may help increase the feed value of silage in your ration,” said Duane Martin, Ph.D., head of marketing for Enogen, Syngenta. “Along with proven competitive yields and strong agronomic characteristics, the efficiency gain reported in this trial shows just how critical a tool Enogen Feed can be for maximizing profit potential.”

The key to Enogen Feed is a unique in-seed alpha amylase technology that converts starch to usable sugars more quickly than other corn, helping to maximize energy. Dairy cattle can more completely use the starch in Enogen Feed grain or silage, which may result in greater efficiency and help significantly lower feed costs for producers.

Researchers presented their findings at the 2019 American Dairy Science Association (ADSA) Northeast Brand meeting in November. In their replicated experiment, the only variable was the type of corn silage fed, so any difference they saw in efficiency was the direct result of Enogen Feed corn’s unique characteristics. In addition to the increase in ECM feed efficiency, researchers saw no negative effect on rumen fermentation.1

“The university data further confirms results seen in extensive research at several universities and commercial trials,” said Eileen Watson, Ph.D., Enogen development specialist, Syngenta. “On average, we’ve found that Enogen Feed corn fed as grain or silage may increase feed efficiency by about 5% compared to corn without the Enogen trait.”

Golden Harvest and Syngenta are committed to accelerating innovation, investing in technologies that matter to bring about positive, lasting change for more sustainable agriculture. In addition to benefits for dairy producers, Enogen Feed hybrids also help deliver high yields in the field. Combining proven genetics and leading traits, the hybrids have consistently performed equal to or better than non-Enogen hybrids. 2

“We know dairy operations are under a lot of pressure. Enogen Feed is here to help,” said Jon Barrett, corn marketing manager, Golden Harvest. “The combination of top-of-the-line yield potential, increased silage quality and proven gain in feed efficiency should help many producers get more out of their rations – and most importantly, help their bottom lines.”
