FermenAider™: your forage quality improvement tool

Applying bacterial inoculants to forage is a crucial component of successful forage fermentation. While indigenous microorganism populations cause fermentation to occur naturally, the use of bacterial inoculants aids and directs the process, resulting in overall better-quality silage.

Beneficial bacteriaFermenAider benefits listed with cows eating

Forage naturally contains species of homofermentative and heterofermentative bacteria. Silage inoculants typically feature homofermentative species of bacteria, since a homofermentative ensiling environment results in reduced dry matter loss, improved palatability, and better retention of nutrition and energy, among other benefits.

Homofermentative bacterial strains used in silage inoculants are selected for their ability to grow rapidly under a range of temperature and moisture conditions. Bacterial species commonly found in silage inoculants include Lactobacillus plantarum or other Lactobacillus species, Pediococcus species, and Enterococcus faecium.

Tip: Applying bacterial inoculants is beneficial only if live bacteria reach the crop. It is essential that bacterial inoculants are properly stored according to manufacturer instructions in order for the bacteria to remain viable.


The enzymes in quality silage inoculant products break down fiber in the forage, and produce sugars that beneficial bacteria can more readily use in the fermentation process. FermenAider™ contains the enzymes amylase, cellulase, B glucanase and hemicellulase.

FermenAider™ silage inoculants deliver viable, naturally occurring microorganisms and enzymes to the crop to ensure that efficient silage fermentation occurs. FermenAider™ is available for dry granular (DG) and water soluble (WS) application.

FermenAider™ contains five strains of homofermentative bacteria, including Lactobacillus plantarum, Pediococcus Pentosaceus, Pediococcus acidilactici, Lactobacillus brevis, and Lactobacillus casei. Each type performs a vital role in the fermentation process.

  • Pediococcus acidilactici and pediococcus pentosaceus rapidly lower pH during the initial phase of fermentation
  • Lactobacillus brevis promotes aerobic stability in the forage
  • Lactobacillus plantarum and Lactobacillus casei serve to keep pH levels low and stable throughout the fermentation process

Tip: Generally speaking, five factors determine the fermentation process: the forage moisture content, the fineness and type of chop, the exclusion of oxygen, the carbohydrate content of the forage, and the bacterial populations present on the forage, both indigenous and as a result of inoculation. Good silage management practices include rapidly filling, properly packing and covering the storage structure. The crop type, storage structure type, and feed-out rate must also be taken into consideration. Bacterial silage inoculants are a forage quality improvement tool that will produce best results along with good management practices.
