A benefit of Fiber Fresh products is they contain an abundance of naturally occurring yeasts distributed throughout the feed material. These yeasts include Saccharomyces cerevisiae, a highly beneficial yeast culture that aids in digestion and improves feed digestibility and utilisation in animals such as horses.
In some Fiber Fresh products, these yeasts occasionally form pure white, odourless patches or clusters mainly on the surface of the product at the top of the bag. The remaining product will smell completely normal when yeast is present.
If you encounter a yeast patch you should not be alarmed as they are harmless and will not cause any injury to you or your animal. However, if you are not comfortable feeding these natural yeasts, simply scrape off the yeast or break away the cluster and discard.
You can rest assured that beneficial yeasts are still present and distributed evenly throughout the remaining product.
Separate to yeast, moulds can form when oxygen is introduced to the bag. Moulds can vary in colour but are typically blue and green and have a strong, pungent odour. The presence of mould signifies the beginning of the deterioration of the feed, therefore any feed affected by mould should not be fed to or consumed by animals including horses and camels. Damaged bags containing mould will often smell flat, musty or off when opened.
Fiber Fresh products are free of moulds as the feed material is sealed airtight under vacuum and free of any oxygen in the package. This oxygen free environment ensures the feed is properly fermented and the nutrients are perfectly preserved. However, if a bag has been compromised, either through a very small hole, a tear or a faulty seal then oxygen will enter the package and start to interact with the product and mould will eventually develop.
To prevent the development of mould, please handle with care and use as instructed by following the opening instructions and Storage instructions on the package.
