ENDOX® - Preserving Feed Quality

Benefits of Antioxidants on Feed Quality—What's Oxidation Costing You?

Rancid fat means quality has been compromised, but what does that mean to your bottom-line? Oxidized fat may:

  • Destroy fat soluble vitamins
  • Reduce the digestibility of fat
  • Reduce palatability and feed consumption through the production of aldehydes during the oxidative process
  • Increase exposure to toxic compounds, which may reduce productivity
  • Reduce energy content available in the feed
  • Increase exposure to free radicals, which may lead to internal oxidative stress concerns
  • Negatively impact gut health, which can lead to future immunity challenges

To protect your finished feed from the negative effects oxidation has on feed quality, an antioxidant system should be used. Antioxidants stabilize fat and maintain feed quality by delaying oxidation. Antioxidants accomplish this by sacrificing themselves to quench the free radicals before the fat or vitamin molecules can be attacked. For the best efficacy and protection, an antioxidant system should be utilized and should contain a combination of the following:

  • Synergistic blend of antioxidants to absorb free radicals before they destroy fatty acids
  • Metal chelators to bind metal ions, which may promote free radical oxidation
  • Oil-based carriers to provide a homogeneous mix into the feed matrix

The Kemin antioxidant systems approach provides the best blend of antioxidants specifically formulated for the protection of your feeds and fats.

ENDOX® Dry and ENDOX® 5X

Formulated specifically to protect finished feeds, ENDOX Dry is a blend of ethoxyquin (EQ), Butylated hydroxyanisole (BHA) and Butylated hydroxytoluene (BHT). ENDOX 5X was developed by Kemin scientists for application into a vitamin premix. ENDOX 5X is a blend of ethoxyquin (EQ) and Butylated hydroxyanisole (BHA).

Why Are ENDOX Products the Products of Choice?

ENDOX is a combination of an inert carrier that has been coated with a synergistic blend of synthetic antioxidants and phosphoric acid. In addition, mono and diglycerides were added to act as surfactants within the antioxidant system. This combination provides adequate distribution of the active components throughout your feed mixture.

The data indicates there was not a significant peroxide problem in any of the individual ingredients with the exception of the supplement. It is especially noteworthy that the fat was of good quality. When the ingredients were combined, oxidation began immediately. Further data, not shown, indicated the problem increased exponentially when the feed was actually placed in the feed bunk.
