  Grazing/Cutting

  Well suited to fodder conservation. Strip or rotational grazing facilitates efficient utilisation and maximum regrowth. Graze at 2.5 to 3 leaf stage.

  Ability to Spread

  Will spread from seed; seed set will occur if ungrazed/not cut and this will be associated with a substantial trade off in nutritive value.

  Weed Potential

  Low unless allowed to set seed.

  Major Pests

  Red and black-headed cockchafer, black field cricket, white-fringed weevil, African black beetle, corbies, underground grass caterpillar.

  Major Diseases

  Rust.

  Herbicide Susceptibility

  Glyphosate.

• Animal Production
  Feeding Value

  High.

  Palatability

  Very palatable feed.

  Production Potential

  High winter growth; rapid spring growth preflowering early summer.

  Livestock Disorders/Toxicity

  Livestock disorders on annual ryegrass are rare. As with other fast growing forages, nitrate toxicity can occur in certain conditions. Bacterial infection of seedhead can occasionally occur and result in ergot poisoning.
