Pet food compositions
Described herein are pet food compositions comprising an amino acid component comprising: lysine; betaine; and glutamic acid and/or a salt thereof present in an amount of about 7 wt. % or more, based on the total weight of the pet food composition; and about 3.3 wt. % or more, of a fatty acid component comprising a fatty acid having an aliphatic tail of 6 to 12 carbons and/or an omega-3 fatty acid, based on the total weight of the pet food composition.
1 . A pet food composition for mitigating gut microbiome putrefaction, comprising:
an amino acid component comprising lysine, betaine, and glutamic acid, wherein lysine is present from 2 wt. % to 3.3 wt. %; the betaine is present from 0.4 wt. % to 0.6 wt. %; and the glutamic acid is present from 3 wt. % to 4.6 wt. %, based on the total weight of the pet food composition;
a fatty acid component comprising: a C8 fatty acid present from 0.5 wt. % to 6.3 wt. %; a C10 fatty acid present from 0.5 wt. % to 6.3 wt. %; and an omega-3 C18 fatty acid present from 0.2 wt. % to 5 wt. %, based on the total weight of the pet food composition; and
a fiber component comprising: a fiber source selected from: flax seed; citrus pulp; beet pulp; cranberry pomace; or a combination thereof, present in an amount of 0.1 wt % to 10 wt %, based on the total weight of the pet food composition,
wherein the weight ratio of lysine:betaine:glutamic acid is from about 5.4:1:7.6 to about 6.5:1:9.1.
2 . The pet food composition according to claim 1 , wherein the weight ratio of C8 fatty acid:C10 fatty acid:omega-3 C18 fatty acid is from about 2.21:1.86:1 to about 2.65:2.23:1.
3 . The pet food composition according to claim 1 , comprising:
from about 1.15 wt. % to about 1.73 wt. % of a C8 fatty acid;
from about 0.97 wt. % to about 1.45 wt. % of a C10 fatty acid; and
from about 0.52 wt. % to about 0.78 wt. % of an omega-3 C18 fatty acid.
4 . The pet food composition of claim 1 , wherein the omega-3 fatty acid is selected from linolenic acid, stearidonic acid, eicosatetraenoic acid, eicosapentaenoic acid, docosapentaenoic acid, docosahexaenoic acid, or a combination thereof.
5 . The pet food composition of claim 1 ,
further comprising caproic acid, caprylic acid, capric acid, lauric acid, or a combination.
6 . The pet food composition according to claim 1 , wherein the amino acid component comprises:
about 2.7 wt. % of lysine;
about 0.5 wt. % of betaine; and
about 3.8 wt. % of glutamic acid.
7 . The pet food composition according to claim 1 , wherein the fiber component comprises flax seed, beet pulp, and cranberry pomace, and wherein the weight ratio of flax seed:citrus pulp:beet pulp:cranberry pomace is from about 2:1.5:1.5:1 to about 2.4:1.8:1.8:1 or about 2:1.5:1.5:1.
8 . The pet food composition of claim 1 , wherein the fiber component comprises:
from about 1.6 wt. % to about 2.4 wt. % of flax seed;
from about 1.2 wt. % to about 1.8 wt. % of citrus pulp;
from about 1.2 wt. % to about 1.8 wt. % of beet pulp; and
from about 0.8 wt. % to about 1.2 wt. % of cranberry pomace.
9 . A method for treating or ameliorating a symptom associated with gut microbiome putrefaction in a companion animal or mitigating gut microbiome putrefaction, the method comprising feeding an effective amount of the pet food composition of claim 1 to the companion animal in need thereof.
10 . The method according to claim 9 , wherein the companion animal is a dog.
