Abstract

The present invention involves methods for improving the quality of the hair of a non-human animal and for increasing the 18-methyleicosanoic acid content of the hair of a non-human animal comprising feeding to the animal an edible composition comprising an effective amount of an amino acid selected from the group comprising isoleucine, threonine, and mixtures thereof.

First claim

1 - 16 . (canceled)

17 . A pet food composition for increasing an 18-methyleicosanoic acid content of hair of a non-human animal, comprising an effective amount of threonine to increase the 18-methyleicosanoic acid content of the hair of the non-human animal, wherein the increase in the 18-methyleicosanoic acid content of the hair improves a quality of the hair.

18 . The pet food composition of claim 17 , wherein at least about 1.0 wt % of the effective amount of threonine is supplemental threonine.

19 . The pet food composition of claim 18 , wherein at least about 1.2 wt % of the effective amount of threonine is supplemental threonine.

20 . The pet food composition of claim 19 , wherein the pet food composition further comprises an effective amount of isoleucine.

21 . The pet food composition of claim 20 , wherein at least about 1.0 wt % of the effective amount of isoleucine is supplemental isoleucine.

22 . The pet food composition of claim 17 , wherein the pet food composition further comprises an effective amount of isoleucine.

23 . The pet food composition of claim 22 , wherein at least about 1.0 wt % of the effective amount of isoleucine is supplemental isoleucine.

24 . The pet food composition of claim 17 , wherein the quality of hair is determined by an improvement selected from: increased hair strength, increased hydrophobicity, increased smoothness, decreased swelling, increased luster, and combinations thereof.

19 . The pet food composition of claim 17 , wherein the effective amount of the threonine is at least about 2.3 wt % of the pet food composition.

20 . The pet food composition of claim 17 , wherein the effective amount of the threonine is about 2.3 wt % of the pet food composition.

21 . The pet food composition of claim 17 , further comprising:
protein in an amount of from 30 wt % to 40 wt %; fat in an amount of from 5 wt % to 15 wt %; carbohydrate in an amount of from 40 wt % to 50 wt %; fiber in an amount of from 0 wt % to 10 wt; mineral mixture in an amount of from 0 wt % to 0.1 wt %; and vitamin mixture in an amount of from 0 wt % to 0.2 wt %.

22 . The pet food composition of claim 21 , wherein the pet food composition comprises 0.05 wt % to 0.1 wt % of the mineral mixture, and 0.15 wt % to 0.2 wt % of the vitamin mixture.

23 . The pet food composition of claim 17 , wherein the pet food composition is a daily ration.

24 . The pet food composition of claim 17 , wherein the non-human animal is a cat.

25 . A method of improving the quality of hair of a non-human animal lacking 18-methyleicosanoic acid in the hair comprising feeding to the non-human animal in need thereof an edible composition comprising an effective amount of isoleucine to increase 18-methyleicosanoic acid in the hair and improve the quality of the hair of the non-human animal.

26 . The method of claim 25 , wherein improving the quality of the hair is evidenced by an improvement selected from: increased hair strength, increased hydrophobicity, increased smoothness, decreased swelling, increased luster, and combinations thereof.

27 . The method of claim 25 , wherein the edible composition is a nutritionally complete food.

28 . The method of claim 25 , wherein the composition is a dry composition.

29 . The method of claim 25 , wherein the composition is a moist composition.

30 . A method of increasing 18-methyleicosanoic acid of the hair of a non-human animal lacking 18-methyleicosanoic acid in the hair comprising feeding to the non-human animal in need thereof an edible composition comprising an effective amount of isoleucine to increase 18-methyleicosanoic acid of the hair, wherein the increase in the 180methyleicosanoic acid of the hair results in an improvement of the quality of the hair.
