Abstract

The present application provides compositions, methods, and systems for reducing allergic response to Fel D1. Such compositions, methods, and systems generally include a supplement comprising an anti-Fel D1 molecule and an animal digest.

First claim

The invention is claimed as follows:

1. A supplement for reducing allergic response to Fel D1, the supplement comprising dried egg yolk powder comprising an anti-Fel D1 molecule that is anti-Fel D1-specific polyclonal immunoglobulin Y (sIgY), the supplement further comprising a dried animal digest that is thermally-treated meat-based enzymatic hydrolysate,
the dried egg yolk powder is about 1 wt. % to about 30 wt. % of the supplement,
the anti-Fel D1 molecule is about 0.0001 wt. % to about 1 wt. % of the supplement, and
the dried animal digest is about 20 wt. % to about 80 wt. % of the supplement.

2. The supplement of claim 1 , further comprising an additive selected from the group consisting of vitamin E, vitamin C, and mixtures thereof.

3. A method of making a supplement for reducing allergic response to Fel D1, the method comprising:
admixing (i) dried egg yolk powder comprising an anti-Fel D1 molecule that is anti-Fel D1-specific polyclonal immunoglobulin Y (sIgY) and (ii) a dried animal digest that is thermally-treated meat-based enzymatic hydrolysate, to form the supplement,
the dried egg yolk powder is about 1 wt. % to about 30 wt. % of the supplement,
the anti-Fel D1 molecule is about 0.0001 wt. % to about 1 wt. % of the supplement, and
the dried animal digest is about 20 wt. % to about 80 wt. % of the supplement.

4. The method of claim 3 , further comprising admixing an additive selected from the group consisting of vitamin E, vitamin C, and mixtures thereof.

5. A system for reducing allergic response to Fel D1, comprising:
a food composition, and
a supplement, wherein the supplement comprises dried egg yolk powder comprising an anti-Fel D1 molecule that is anti-Fel D1-specific polyclonal immunoglobulin Y (sIgY), the supplement further comprising a dried animal digest that is thermally-treated meat-based enzymatic hydrolysate, the dried egg yolk powder is about 1 wt. % to about 30 wt. % of the supplement, the anti-Fel D1 molecule is about 0.0001 wt. % to about 1 wt. % of the supplement, and the dried animal digest is about 20 wt. % to about 80 wt. % of the supplement.

6. The system of claim 5 , wherein the food composition is a cat food.

7. A method for reducing allergic response to Fel D1, comprising:
adding a supplement to a food composition, wherein the supplement comprises dried egg yolk powder comprising an anti-Fel D1 molecule that is anti-Fel D1-specific polyclonal immunoglobulin Y (sIgY), the supplement further comprising a dried animal digest that is thermally-treated meat-based enzymatic hydrolysate, the dried egg yolk powder is about 1 wt. % to about 30 wt. % of the supplement, the anti-Fel D1 molecule is about 0.0001 wt. % to about 1 wt. % of the supplement, the dried animal digest is about 20 wt. % to about 80 wt. % of the supplement; and
administering the food composition to a cat.

8. The method of claim 7 , wherein administration is a regular administration.
