Silage Additives

NWF Ultra Guard Range

NWF Ultra Guard & Ultra Guard Plus silage additive range delivers unrivalled fermentation and stability for all crops and conditions.

NWF Ultra Guard is specially designed to optimise the fermentation process, maintain good palatability and to improve the forage digestibility in low sugar forages.

Features & Benefits

  • Rapid pH drop in the silo
  • Rapid inhibition of Clostridia and Enterobacteria
  • Better forage digestibility
  • Lower dry matter loss at the ensiling phase
  • Greater nutritive value, less energy loss, less protein breakdown and better fibre degradability

NWF Ultra Guard Plus is specially designed for all higher dry matter crops to reduce losses from the presence of yeasts and moulds, and to keep silage fresh and palatable longer.

Features & Benefits

  • Inhibition of yeasts and moulds
  • Greater aerobic stability. Longer stability of the silage at opening, lower dry matter loss and higher protection from aerobic spoilage
  • Greater feeding value. Lower nutrient loss due to aerobic challenges, higher energy value as a result of Lactobacillus buchneri NCIMB 40788 and improved animal performance
