Rumen-Protection System for Feed Ingredients

Technology Benefits

No FDA approval required Utilizes only natural, plant-or animal-derived ingredients Can be used in organic dairy Involves accepted food-and feed ingredients and unit operations

Technology Application

Modification of physico-chemical and sensorial characteristics of milk and dairy products (e.g. improved spreadability of butter or controlling flavor development in cheese) Modulate the composition of milk in a way that significantly enhances the nutritional value and health benefit (e.g. production of milk high in Omega-3 fatty acids) Orally deliver medicaments, potentially easing vaccination and other therapeutic interventions

Detailed Technology Description

A delivery system that protects feed ingredients (e.g. nutrients, medicaments) as they pass through the rumen of cattle (or other ruminant animals) has been developed by UC Davis researchers. This system enables ingredients to pass through the rumen unmodified. Allowing presentation of these protected feed ingredients to the intestine, where they can be absorbed into the bloodstream and utilized by the animal - including being incorporated into the milk. This system has been used for example, to elevate the level of Omega-3 fatty acids in cow's milk, by preventing omega-3s that have been protected with this system from modification in the rumen after being fed to the animal.

Title: Method and compositions for preparing and delivering rumen protected lipids, other nutrients and medicaments
Usefulness: Method and compositions for preparing and delivering rumen protected lipids, other nutrients and medicaments
Summary: The composite gel is used, e.g. for delivering unmodified amino acids, lipids, and/or feed supplements through the rumen of a ruminant animal. It is used for protecting lipids, proteins, and/or other supplements during passage through a rumen. It can be, e.g. fed to cattle or other ruminants, by which lipids, nutrients, and/or bioactive molecules can pass through the rumen.
Novelty: Composite gel for delivering unmodified amino acids, lipids, and/or feed supplements through the rumen of a ruminant animal comprises a dispersed phase of lipid droplets, and a continuous phase aqueous matrix of crosslinked protein(s)
