Agri-King has been serving customers in the United States since the company was founded in 1968. In 1997, Agri-King Limited was established in the United Kingdom, introducing Agri-King products to the European market. Several years later, Silo-King® was registered in Canada and joined the Canadian marketplace.

What Sets Silo-King Apart?

  • Less Heating – Antioxidants scavenge oxygen within the forage or grain, minimizing respiration and heating to reduce dry matter loss and retain more nutrients.
  • Increased Digestibility – Enzymes break down the cell wall and predigest stem fibres and grain starches, unlocking valuable nutrients and allowing the forage or grain to be more easily digestible in the rumen.
  • Enhanced Palatability – Reduced spoilage helps retain sugars to reduce secondary fermentation, which allows for improved palatability for livestock.
  • More Energy – Improved digestibility and nutrient retention help make for higher quality feeds with more available energy.
  • Improved Storage Life – Spoilage and heating are controlled to improve bunk life, resulting in minimized dry matter loss.


Key Ingredients

  • Lactic Acid Bacteria (LABs) – Controls ensiling process to completion; reduces dry matter loss; lowers pH for quicker fermentation
  • Enzymes – Predigests complex fibres and grain starches, increasing digestibility and sugars while releasing more
    energy for rumen microorganisms
  • Food-grade Antioxidants – Maintains oxygen-free environment to limit rancidity and growth of “spoilage organisms”.
