These perennial ryegrass varieties are engineered to enhance livestock nutrition, boost productivity, and contribute to environmental sustainability.
HSG Varieties improve digestibility through increased levels of water-soluble carbohydrates (WSC) in the plant.
Unlike traditional ryegrass varieties, where some protein in the forage remains undigested and is lost as waste, HSG sugars are a source of readily available energy soon after forage enters the rumen, fuelling the rumen microbes to process more of the grass protein.
This protein can then be used in the production of milk and meat, rather than being excreted.
Two standout varieties in the HSG range available exclusively in Australia from Upper Murray Seeds (UMS) are AberGreen AR1 and AberGain AR1.
These advanced late-maturing perennial ryegrass varieties offer excellent growth characteristics and are designed to provide superior forage for grazing systems.
AberGreen AR1 is a deep-rooted diploid perennial that offers robust yields, resilience under grazing pressure, and enhanced feed value.
AberGain AR1 is a tetraploid variety that excels in producing highly digestible forage with exceptional palatability, making it an ideal choice for intensive livestock production systems.
Both varieties significantly improve digestibility compared to standard ryegrass varieties and provide high-energy forage ideal for boosting milk and meat production.
These grasses also address environmental sustainability.
The high level of WSC in Aber HSG varieties provides more readily fermentable energy. Research at the Institute of Biological, Environmental and Rural Sciences (IBERS) shows this increases the capture of rumen degradable protein into microbial protein and reduces the amount of nitrogen lost in the urine.
“The Aber High Sugar Grass range is a game-changer for Australian farmers, offering superior forage quality, improved livestock performance, and greater sustainability,” Upper Murray Seeds general manager David Lockhart said.
“At Upper Murray Seeds, we’re proud to offer this innovative solution to the Australian market, helping farmers achieve more productive and resilient pastures.”
He said the introduction of AberGreen AR1 and AberGain AR1 into pasture systems offers a dual solution to modern farming challenges, driving higher yields and contributing to environmental stewardship.
“As pasture seed innovation continues to play a crucial role in Australian agriculture, these grasses stand out as variety leaders.”
