Assessing the palatability and nutritional value of Matricaria to grazing sheep locations
Aims
  • To determine whether sheep graze on matricaria (palatability of the weed) in a mixed species pasture and if so at which growth stages is the weed palatable.
  • Estimate the feed value of matricaria at various growth stages compared to other available feed.
  • Evaluate the use of MCPA to increase matricaria palatability.
  • Evaluate the efficacy of late flowering mowing or weed wiping to control matricaria compared to district practice of spray topping.
Key messages
  • Spray topping remains the most effective control option for matricaria in pastures.
  • Sheep did not graze matricaria at any growth stage and the use of MCPA in a spray-graze scenario did not increase grazing of matricaria. Grazing would not be a reliable control method for matricaria, even when paired with chemical manipulation, in an average year.
  • Matricaria had good feed value but had less crude protein and metabolisable energy than the other green feed in the paddock.
  • Mowing or weed wiping to control matricaria at the flowering stage was significantly less effective in reducing biomass and number of flowers and had significantly more regrowth compared to district practice of spray topping.
