Abstract
Method for incorporating polyunsaturated fatty acids into milk with improved efficiency. The methods include protecting the polyunsaturated fatty acids, including omega-3 and omega-6 polyunsaturated fatty acids, with a protective agent prior to feeding the fatty acids to a milk producing animal. Methods for feeding polyunsaturated fatty acids to milk producing animals by top dressing a polyunsaturated fatty acid supplement on top of animal feed compositions and methods of making and using such compositions are also provided.
Claims29
A composition comprising a polyunsaturated fatty acid (PUFA) and a protective fat, wherein said PUFA comprises an omega-3 PUFA, omega-6 PUFA or a combination thereof.
A method of making a composition comprising a PUFA and a protective fat, comprising the steps of:
- (a) obtaining the PUFA, wherein said PUFA comprises omega-3 PUPA, omega-6 PUFA, or a combination thereof;
- and
- (b) combining the protective fat with the PUFA to produce the composition.
A method of obtaining milk enriched with omega-3 PUFA, omega-6 PUFA or a combination thereof in an animal capable of producing milk, comprising the steps of:
- (a) obtaining a PUFA, wherein said PUFA comprises omega-3 PUFA, omega-6 PUFA, or the combination thereof;
- (b) combining a protective fat with the PUFA to produce a mixture thereof;
- (c) feeding the animal said mixture in an amount effective to produce enriched milk;
- and
- (d) extracting milk from the animal to obtain said enriched milk.
A method of producing PUFA-enriched milk, comprising the steps of:
- (a) adding a layer comprising omega-3 PUFA, omega-6 PUFA, or a combination thereof on top of feed to form a layered feed, wherein the PUFA layer contains an effective amount of PUFA to produce PUFA-enriched milk;
- and
- (b) feeding said layered feed to a milk-producing animal.
