What’s the goal for your silage inoculant? That’s the question that Richard Muck, agricultural engineer with the U.S. Dairy Forage Research Center, wants you to ask before you buy a silage inoculant. There are two main types of inoculants:

  • Traditional homofermentative types, such as Lactobacillus plantarum.
  • Heterofermenter types, such as Lactobacillus
    buchneri. 

Each works differently and should be used in different situations, explains Muck. He recommends the following rules-of-thumb:

  • If you want to make good silage better, use a homofermenter.
  • If you need to improve aerobic stability, use a heterofermenter.
