Mould inhibitors

Moulds consume valuable nutrients, make feed unpalatable and produce toxins.

Mould spores are present within plant material and environment. Animal feed and raw materials provide the nutrients required for their development. Moisture content is critical for mould development, more specific the available water (Aw-value). The Aw-value expresses the amount of available water for microbial growth and should not exceed 0.6. Even moisture levels of 11-12% can result in an Aw-value higher than 0.6. Climate, harvest and storage conditions (e.g. condensation in silos) will have a significant impact on the Aw-value. Temperature and grain breakage are important factors which will mainly affect the rate of mould  reproduction.

Mould growth will have an important impact on feed quality. Losses on dry matter can go up to 20% (mainly energy and proteins) and mycotoxins, produced by moulds, will be detrimental to animal health and performance. Due to changes in physical properties, problems such as “crust formation” in silos might occur, as well as palatability issues.

Control of moulds in cereals and feed is based on a number of principles

  • Clean, well aerated silos and transport systems.
  • Monitor moisture, Aw-value and temperature.
  • Monitor production processes such as pelleting and extrusion.
  • Apply high quality additives (dosage depends on moisture content and storage time)
  • Apply mould inhibitors as soon as possible in the production chain (feed materials), in order to preserve quality (mycotoxin) and nutritional value.
  • Apply mould inhibitors in raw materials and in feed as a preventive measurement. It will guarantee safe raw materials and feed from raw material producer up to the farm.
  • Use appropriate application equipment

The physical structure of the different feed components is altered in the time between harvest, drying and processing. It will result in a lower water holding capacity, which will negatively affect the feed moisture content. Nevertheless, optimal moisture content has to be achieved in order to optimize digestion and maintain nutrient availability. Optimization of moisture levels will improve feed processing in terms of reduced energy consumption and increased output. Especially for pelleted feed, an improved pellet quality and durability can be expected.
