ENDOX brand antioxidant is a combination of an inert carrier that has been coated with a synergistic blend of synthetic antioxidants and citric acid. This combination provides adequate distribution of the active components throughout your feed mixture. Proven efficacy backed up by 50 years of use in feeds of varying composition and storage conditions, worldwide.
In laboratory, the benefit of using an antioxidant to stabilise a feed can be demonstrated via an accelerated test (i.e. the OXITEST). This is a routine analysis at Kemin and the following example demonstrates how the inclusion of a standard dosage of ENDOX D dry is able to significantly improve feed shelf life.
An improvement of 23% in an accelerated test stressing the feed at a temperature of 100 degree Celsius, which resulted in a significant stability to oxidation in feed stored in standard conditions (20 C). In fact, considering the induction point of negative control was around 13 h, and estimating a Q10 factor of 2.3, the feed stabilised with ENDOX D dry will be more resistant to oxidation for approximately 100 extra days. In other words, a feed stabilised with ENDOX D dry can be stored for more than 3 months longer than an unsterilized feed.
The preservation of fat quality in feed is extremely important. 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 the energy content of the feed
Reduce palatability and feed consumption
Increase the animal’s exposure to free radicals, which may lead to internal oxidative stress
Increase exposure to toxic compounds, which may reduce productivity
Negatively impact gut health, which can lead to future immunity challenges
To protect your finished feed from the negative effects that oxidation has on feed quality, an antioxidant program should always be applied. The program should begin with the stabilization of feed ingredients sensitive to oxidation and end with a supplementary addition of antioxidants to the final feed.
The inclusion of an antioxidant in complete feeds helps to maintain their quality by delaying oxidative chain reactions which are potentially triggered by production processes or the presence of pro-oxidant ingredients.
Antioxidants slow down the oxidative process by sacrificing themselves for consumption by free radicals before the fat or vitamin molecules can be attacked.
Improving fat preservation with an antioxidant system 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
Moreover, due to the relatively low inclusion rate of antioxidants in final feeds, optimal physical properties are also required to deliver uniform distribution throughout the feed giving maximum efficacy.
Kemin’s fat quality solution is an antioxidant system approach, which provides the best blend of antioxidants specifically formulated for the protection of your feeds and fats.
ENDOX brand antioxidants for animal feed are developed for the treatment of complete feeds and premixes. Each formula is specifically designed with the correct level of active antioxidants, to fit customer needs. ENDOX D dry and ENDOX ME dry are designed for application in feed with different fat levels, while the concentrated form ENDOX 5X Conc. is more suitable and cost effective for application in premixes.
All ENDOX brand antioxidants include the following:
An inert carrier that has been coated with a synergistic blend of synthetic antioxidants - ethoxyquin (EQ), Butylated hydroxyanisole (BHA) and a metal chelator
Small particle size allowing for homogeneous distribution of the antioxidant throughout the premix and finished feed
Increased active surface area allowing for every particle to be active and more effective at sequestering free radicals
ENDOX brand antioxidants are available in 25 kg bags.
