Improved fiber digestibility impacts animal performance.

With new Alforex alfalfa varieties featuring High-Gest Alfalfa Technology, growers can get improved fiber digestibility and forage quality along with management flexibility.

Improved fiber digestibility

Lignin is the complex organic compound that hardens and strengthens the plant’s cell walls. In mature plants, lignin increases yield but negatively affects forage quality. To minimize this dilemma, producers have traditionally had to find a compromise between yield and quality by harvesting at late-bud stage to one-tenth flower.

Better digestibility for more milk

Varieties with Hi-Gest increase the rate of fiber digestion by 5-10%, which improves animal intake; increases the extent of fiber digestion (as measured by uNDF240) by 5-10%; and raises crude protein by 3-5%.* The net impact can be 2.5 or more pounds of milk per cow per day.

During the 2015 growing season, more than 10,000 acres of Hi-Gest 360, 660 and AFX 1060 with Hi-Gest Alfalfa Technology were planted in key production areas across the U.S. Those on-farm tests showed Hi-Gest actually reduced indigestible fiber at 240 hours (uNDF240) by 22% and increased crude protein by 11% versus the Rock River Laboratory’s running averages.**

More harvest flexibility

Varieties with Hi-Gest provide the management flexibility to work around the weather or manage tonnage and quality to maximize return per acre. Producers can get even higher quality dairy hay at their normal cutting schedule or choose to increase yield  and maintain harvest quality of conventional varieties at there normal cut date.

Ready for your fields, no special management or stewardship required

After years of testing, varieties in the fall dormancy groups 3, 4, 6, 9 and 10 were advanced commercially and launched under the Hi-Gest Alfalfa Technology registered trademark in 2014 and 2015. Patents are pending for all varieties and hybrids with Hi-Gest Alfalfa Technology. The patent for Hi-Gest 660 has been granted.

Alfalfa growers will not need to change their management practices to benefit from the use of Hi-Gest alfalfa for haylage or hay. As a non-transgenic technology, Hi-Gest forage production fields do not have or require special stewardship management considerations.

*The increased rate of fiber digestion, extent of digestion, and crude protein data was developed from replicated research and on-farm testing. During the 2015 growing season at West Salem, WI and Woodland, CA, the following commercial dormant, semi-dormant and non-dormant alfalfa varieties were compared head-to-head with Hi-Gest® alfalfa for rate of digestion, extent of digestion and percent crude protein: America’s Alfalfa Brand AmeriStand 427TQ, Croplan Brands LegenDairy XHD and Artesia Sunrise, Fertizona Brand Fertilac, S&W Seed Brands SW6330, SW7410 and SW10 and W-L Brands WL 319HQ and WL 354HQ. Also during the 2015 growing season, 32 on-farm Hi-Gest hay and silage samples were submitted to Rock River Laboratory, Inc., for forage analysis. The results for rate of digestion, extent of digestion and percent crude protein were averaged and compared to the 60-day and four-year running averages for alfalfa in the Rock River database which included approximately 1,700 alfalfa hay and 3,800 silage 60-day test results and 23,000 hay and 62,000 silage tests results in the four-year average.

**Crude protein= 60-day running averages and uNDF240=4-year running average
