Balancing feed costs and animal productivity are a challenge for animal nutrition and health professionals. Lipid oxidation compromises the nutritional quality of animal feeds by degradation of essential ingredients like polyunsaturated fatty acids, vitamins, pigments and others. Together with the negative impact on feed palatability, oxidation leads to a lower animal performance. While poor animal performance is of economic importance, formation of reactive compounds like free radicals or aldehydes will have a negative effect on the health of animals.

Inclusion of specific antioxidants is essential to prevent or slow down lipid oxidation in animal feeds. 


Safe raw materials and feeds

Guaranteed oil, premix and feed quality with improved shelf life

Preservation of costly essential feed ingredients

Contributes to an improved animal performance and health


When freshly harvested grain is fed to pigs it often results in problems with the productivity. When the grain is harvested many biological processes are still ongoing. These are mainly enzymatic reactions such as the activity of the lipoxygenase enzyme. Upon grinding of freshly harvested grain the enzymes are liberated and become active. The lipoxygenase enzyme promotes oxidative reactions. Stabilization of the feed with an additional amount of antioxidants is able to overcome the negative aspects associated with feeding animals freshly harvested grain.

An extensive field survey reveals large variation in oxidative oil quality

Variability in feed raw materials, such as fats and oils, is a very common issue and can influence feed variability and animal performance. Today, CLS offers an exclusive service called the Lipid Evaluation Test (LET), with a serie of analyses to assess both oxidative and nutritional characteristics of fats and oils. Since its launch, more than 930 lipid samples have been analyzed in the LET test. It shows the large variation present between lipid sources. The compiled dataset helps to fully understand the huge variability in oxidative quality of fats and oils present in todays feed market. Kemin’s CLS will thoroughly screen your fat or oil sample for it’s quality after which we offer a tailored antioxidant solution to you.
