AberGain Perennial Ryegrass


A late-maturing, tetraploid perennial ryegrass which sets a new standard in grass production and nutritional quality.

  • A premium High Sugar Grass that can significantly improve the utilisation of protein from grass for increased meat and milk production, while lowering methane production
  • Low endophyte
  • Excellent early grazing and substantial silage yields
  • Very high levels of digestibility and palatability throughout the growing season
  • Exceptional yield with abundant early spring and late autumn growth

Features, Advantages and Benefits

AberGain HSG is the ultimate in tetraploid perennial ryegrass from the IBERS breeding program at Aberystwyth University in Wales which has been running for over 30 years. As part of the IBERS long-term trials program. AberGain is monitored for water-soluble carbohydrate (WSC) content as well as all other agronomic and performance attributes.

AberGain is a High Sugar Grass (HSG) that was specifically bred with higher levels of WSC to provide extra energy to microbes in the animals’ rumen and so the animal can digest and use more of the protein from forage to increase milk production and live weight gain.

AberGain HSG has outstanding season-long performance, with the highest summer and autumn grazing yield of any late- maturing perennial ryegrass, and the highest spring grazing yield of any late tetraploid. Its combination of dry matter yield and herbage quality means AberGain out-performs all other varieties for ME yield, whether under grazing or conservation management.

AberGain HSG presents farmers with all the traditional yardsticks such as yield, persistence and disease resistance, but more important is its capacity to increase production of meat and milk by up to 24% and reduce methane emissions and nitrogenous pollutants by up to 20%.

Cattle and sheep are poor converters of grass protein into milk and meat. When grazing a standard ryegrass, livestock use only about 20% of protein from the forage for production - and the rest is degraded to rumen ammonia and wasted in faeces and urine. This is not only financially costly, but also detrimental to the environment.
