SF Adrenalin

A winter feed and silage star

SF Adrenalin is a tetraploid annual ryegrass developed from three components and selected for fast establishment, good early feed and improved standability for fodder conservation. It is capable of several grazings or cuts and will produce high yields of leafy foliage throughout the growing season, and has outstanding recovery from grazing or cutting. SF Adrenalin is a late season variety flowering some nine days later than Tetila types, and just one day after Winter Star II. It has a higher dry matter percentage than Winter Star II for improved early silage, but also has lower NDF and higher ME levels.

Agronomic features:
  • High yielding
    More feed for your pasture investment

  • High winter yields
    Provides feed when it is needed most

  • Excellent late season quality
    Enables higher quality conserved fodder which will provide more meat and milk per hectare
