Definitions

  • the present invention relates to an animal feed composition, a process to produce the animal feed composition and the use of an interesterified triglyceride composition for reducing oil-leakage from an animal feed composition.
  • High amounts of digestible lipids, in particular liquid oils, are often desirable in animal feed compositions, as they are beneficial for the growth and development of animals.
  • Liquid oils are not only used as sources of energy because of their high caloric value. They also offer essential fatty acids and are important for the absorption of fat-soluble vitamins and pigments. Additionally, liquid oils play a beneficial role in structural properties of the meat of the animals and an improvement of palatability when the meat is consumed. The incorporation of high amounts of liquid oils in animal feed compositions is difficult to achieve since the liquid oil needs to be structurally retained in the feed composition.
