Dry Antioxidants to Preserve Feed Quality

ENDOX® Dry Antioxidants are formulated specifically for the treatment of finished feeds and premixes. Each ENDOX product is a combination of an inert carrier coated with a synergistic blend of synthetic antioxidants, metal chelators and surfactants, which adequately distribute to protect feed from fat oxidation, vitamin degradation and more.

Features and Benefits

  • Synergistic blend of synthetic antioxidants to absorb free radicals before they destroy fats and vitamins
  • Chelators to bind metal ions, which may otherwise promote free radical oxidation
  • Proprietary manufacturing process ensures all carrier molecules are coated with the active antioxidant mixture
  • Antioxidant blends specifically formulated for finished feeds and vitamin premixes
  • Customer Laboratory Services (CLS)-supported product line for helping customers evaluate fat quality

ENDOX Antioxidant Systems

Synthetic antioxidants like butylated hydroxyanisole (BHA), butylated hydroxytoulene (BHT) and ethoxyquin (EQ) are commonly used to provide oxidative stability to fats, vitamins and other nutrients in finished feeds. Conventional antioxidant mixtures for feeds are often simple, dry mixtures containing crystals of the antioxidants and carriers. In contrast, ENDOX Dry Antioxidants are manufactured using a proprietary process where active antioxidants are applied to the surface of a dry carrier. This ensures nearly every particle is covered with an active mixture and allows for the homogenous distribution of the antioxidants throughout the feed or premix. ENDOX products contain research-backed blends of antioxidants specifically developed by Kemin scientists for protection of finished feeds or vitamin/trace mineral (VTM) premixes.

So, although they make up less than 1 percent of the diet, vitamins are vital ingredients for optimal growth, health, reproduction and performance of livestock and poultry.
