Feed: preservation

Contributor(s): Alastair Macrae, Liam Sinclair

Introduction

  • There are a number of techniques that farmers utilize to preserve feedstuffs.
  • The basic aim is to preserve food during a time of plenty (for example grazed grass during peak grass growth in the summer/rainy season) or cheap (for example cereal harvest), so that it can be stored, and be available for feeding during a period with reduced feed availability and/or higher cost.
  • Feedstuffs need to be preserved so that deterioration in quality is minimal (preserving energy, protein and mineral levels).
  • Preservation also needs to prevent growth of harmful microorganisms, eg bacteria such as Listeria monocytogenes Listeria monocytogenes, or molds/mycotoxins.
