Compositions and Methods for Feeding Domesticated Animals
The subject invention provides methods and compositions for feeding domesticated animals. In certain embodiments, compositions comprising a microorganism and/or a microbial growth by-products is contacted with an animal's food and/or drinking water. Preferably, the growth by-product is a biosurfactant. Advantageously, the subject invention can promote good health and well-being in a domesticated animal by, for example, enhancing the animal's immune system, promoting digestive health, providing nutrients to the animal and promoting dental/oral cavity health. Furthermore, the subject invention can be used to prolong the shelf life of pet food and prevent contamination of food from deleterious microorganisms.
1 . A method for feeding a domesticated animal, wherein a composition comprising a biosurfactant-producing microorganism and/or a growth by-product thereof, is formulated into the animal's food and/or drinking water prior to the animal ingesting the food and/or drinking water.
2 . The method of claim 1 , wherein the growth by-product is a biosurfactant.
3 . The method of claim 2 , wherein the biosurfactant is a glycolipid selected from sophorolipids, rhamnolipids, mannosylerythritol lipids, cellobiose lipids and trehalose lipids.
4 . The method of claim 2 , wherein the biosurfactant is a lipopeptide selected from surfactin, iturin, fengycin, arthrofactin and lichenysin.
5 . The method of claim 2 , wherein the biosurfactant is a phospholipid.
6 . (canceled)
7 . The method of claim 2 , wherein the biosurfactant is in crude form, said crude form comprising the biosurfactant in fermentation broth in which a biosurfactant-producing microorganism was cultivated.
8 - 11 . (canceled)
12 . The method of claim 1 , wherein the animal's food or water contains a nutrient for promoting the animal's health and/or well-being, and wherein the bioavailability of the nutrient to the animal's digestive tract is enhanced by the composition that has been formulated into the food or water.
13 . A method for prolonging the shelf-life of pet food, wherein a composition comprising a biosurfactant-producing microorganism and/or a microbial growth by-product thereof, is formulated into the pet food.
14 . (canceled)
15 . A composition for feeding a domesticated animal, the composition comprising a biosurfactant-producing microorganism and/or a growth by-product thereof, wherein the growth by-product is a biosurfactant.
16 . The composition of claim 15 , wherein the biosurfactant is a glycolipid selected from sophorolipids, rhamnolipids, mannosylerythritol lipids, cellobiose lipids and trehalose lipids.
17 . The composition of claim 15 , wherein the biosurfactant is a lipopeptide selected from surfactin, iturin, fengycin, arthrofactin and lichenysin.
18 . The composition of claim 15 , wherein the biosurfactant is a phospholipid.
19 . (canceled)
20 . The composition of claim 15 , wherein the biosurfactant is in crude form, said crude form comprising the biosurfactant in fermentation broth in which a biosurfactant-producing microorganism was cultivated.
21 . The composition of claim 20 , comprising the crude form biosurfactant without the microorganism that produced it.
22 . The composition of claim 15 , further comprising water, wherein the water is an animal's drinking water.
23 - 26 . (canceled)
27 . The composition of claim 15 , further comprising one or more nutrients for animal health.
28 . The composition of claim 27 , wherein the one or more nutrients are selected sources of amino acids, peptides, proteins, vitamins, microelements, fats, fatty acids, lipids, carbohydrates, sterols, enzymes, and trace minerals.
