ANIMAL FEED SUPPLEMENT AND METHODS OF MAKING
A solid animal feed composition generally includes a liquid nutrient component in an amount of 1% to 40% by weight and a fatty acid component in an amount of 60% to 99% by weight. The solid animal feed composition has a melting point of at least 70° F. The animal feed composition can be fed to lactating dairy cows to increase milk production, increase the fat content of milk produced by the cow, and/or increase the protein content of milk produced by the cow.
1 . An animal feed composition comprising:
a liquid nutrient component in an amount of 1% to 40% by weight;
a fatty acid component in an amount of 60% to 99% by weight; and
a melting point of at least 70° F.
2 . The animal feed composition of claim 1 , wherein the liquid nutrient component is present in an amount of from 1% to 25%.
3 . The animal feed composition of claim 1 , wherein the composition has a Shore A hardness of at least 50.
4 . The animal feed composition of claim 1 , wherein the liquid nutrient comprises a liquid analog of a solid nutrient.
5 . The animal feed composition of claim 1 , wherein the liquid nutrient comprises a liquid analog of methionine.
6 . The animal feed composition of claim 1 , further comprising tallow, lard, corn oil, soy oil, coconut oil, palm oil, palm stearin, a hydrogenated fat, a non-hydrogenated fat, an emulsifier, a fat-soluble vitamin, an organic acid, a cation, or any combination of two or more of the foregoing.
7 . The animal feed product of claim 1 , wherein the melting point is at least 120° F.
8 . A method of making a solid animal feed supplement from liquid materials, the method comprising:
melting a fatty acid composition;
adding a liquid nutrient to form an intermediate mixture; and
cooling the intermediate mixture in a manner effective to produce a solid animal feed supplement.
9 . The method of claim 8 , wherein cooling the intermediate mixture comprises introducing the intermediate into a prilling tower.
10 . The method of claim 8 , wherein the solid animal feed supplement has a Shore A hardness of at least 50.
11 . The method of claim 8 , wherein adding the liquid nutrient forms an intermediate mixture having a fatty acid:liquid nutrient ratio of from 99:1 to 75:25, by weight.
12 . The method of claim 8 , wherein the liquid nutrient comprises an analog of methionine.
13 . A method of increasing milk production in a lactating cow, the method comprising:
administering to the lactating cow a nutritional supplement comprising the animal feed composition of claim 1 .
14 . A method of increasing milk fat content in milk with low fat content produced by a lactating cow, the method comprising:
administering to the lactating cow a nutritional supplement comprising the animal feed composition of claim 1 .
15 . A method of increasing milk protein content in milk with low protein content produced by a lactating cow, the method comprising:
administering to the lactating cow a nutritional supplement comprising the animal feed composition of claim 1 .
