Fat Soluble Vitamins – Factors Affecting Stability!


Moisture, light, oxygen, acidity, abrasion, fat rancidity, carrier, enzymes and

medications affect vitamin stability in premixes and complete feeds.

Vitamins are organic compounds sensitive to a myriad of physical and chemical reactions

that affect their potency. For example, vitamin A has five double bonds highly susceptible to

oxidation, whereas vitamin E is a natural antioxidant rapidly consumed without its own

protection. During feed manufacturing and storage, oxidative conditions often arise that may

reduce vitamin stability. Unless vitamin destruction is prevented or compensated, animal

performance may be reduced depending on severity and duration of imposed vitamin

deficiency
