BACKGROUND

[0001] Increasing production and fat content of milk obtained from lactating ruminants has been a major goal for dairy farmers. Additional milk production per ruminant is beneficial because it results in a higher yield, thereby increasing profits. Increased milk fat is desirable because it has a higher economic value and can be used in highly desirable food products, such as cheese, yogurt, and the like.

[0002] A common approach to increasing either or both production and milk fat contents includes adjusting feed, nutrients, elements, vitamins, supplements, and/or the like provided to the ruminant. One such specific method includes feeding the ruminant a total mixed ration (TMR), which is a mix of grain and silage with some protein meals, such as, for example, soya bean meal and canola meal. Additional materials and trace elements, vitamins, extra nutrients, and the like may also be added to the TMR.

[0003] However, the current methods and feeds used to increase milk fat content tend to lower milk production, lower protein content, and/or have other detrimental effects on the ruminant. Furthermore, the methods and feeds oftentimes result in other undesired effects, such as increased trans fatty acid levels on the fatty acid profile of the milk fat.

SUMMARY

[0004] In an embodiment, a dietary paste composition may include at least one saturated fatty acid compound and at least one carrier component.

[0005] In an embodiment, a method of increasing fat content in milk may include providing a dietary paste composition to a ruminant for ingestion. The dietary paste composition may include at least one saturated fatty acid compound and at least one carrier component. [0006] In an embodiment, a method of preparing a dietary paste composition may include contacting at least one saturated fatty acid compound with at least one carrier component to form the dietary paste composition.

[0007] In an embodiment, a method of preparing a dietary paste composition may include dispersing at least one saturated fatty acid compound in water to form a colloid and combining the colloid and at least one carrier component to form the dietary paste composition.

DETAILED DESCRIPTION

[0010] This disclosure is not limited to the particular systems, devices and methods described, as these may vary. The terminology used in the description is for the purpose of describing the particular versions or embodiments only, and is not intended to limit the scope.

[0011] As used in this document, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art. Nothing in this disclosure is to be construed as an admission that the embodiments described in this disclosure are not entitled to antedate such disclosure by virtue of prior invention. As used in this document, the term "comprising" means "including, but not limited to." [0012] The following terms shall have, for the purposes of this application, the respective meanings set forth below.

[0013] A "ruminant" is a class of mammal with a multiple chamber stomach that gives the animal an ability to digest cellulose -based food by softening it within the first chamber (rumen) of the stomach and regurgitating the semi-digested mass. The regurgitate, known as cud, is then chewed again by the ruminant. Specific examples of ruminants include, but are not limited to, cattle, bison, buffaloes, yaks, camels, llamas, giraffes, deer, pronghorns, antelopes, sheep, and goats. The milk produced by ruminants is widely used in a variety of dairy-based products. Dairy cows are of considerable commercial significance for the production of milk and processed dairy products such as, for example, yogurt, cheese, whey, and ice cream.

[0014] "Silage" refers to a feed that includes chopped green forage, such as, for example, grass, legumes, and field corn. The silage is placed in a structure or a container that is designed to exclude air. The silage is then fermented in the structure or container, thereby retarding spoilage. Silage can have a water content of about 60% to about 80% by weight.

[0015] A "paste" is a viscous substance that behaves as a solid until a sufficiently large load or stress is applied, at which point it flows like a fluid. Pastes may include a suspension of granular material in a background fluid. The individual grains are dispersed together like sand on a beach, forming a disordered, glassy or amorphous structure, and giving pastes their solid-like character. Unlike pastes, liquids have very low viscosities, and solids have extremely high viscosities (in some cases, essentially infinite)..

[0016] The present disclosure relates generally to dietary compositions such as supplements and the like that can be fed to ruminants for purposes of affecting milk production in the ruminant. Particularly, the dietary compositions described herein may be fed to a ruminant to increase the amount of milk produced by the ruminant and/or to increase the fat content of the milk produced by the ruminant, as described in greater detail herein. Specific compositions described herein may be in a dietary paste form.

[0017] When a ruminant consumes feed, the fat in the feed is modified by the rumen to provide a milk fat profile that is different from the profile of fat in the feed. All fats which are not completely inert in the rumen may decrease rumen digestibility of the feed material. Milk composition and fat quality can be influenced by the ruminant's diet. For example, oil feeding can have negative effects on both rumen function and milk formation. As a result of the oil feeding, the milk protein concentration is lowered, the fat concentration is decreased, and the proportion of trans fatty acids is increased. These have been connected especially to an increase in the harmful low-density lipoprotein (LDL) cholesterol and to a decrease in the beneficial high-density lipoprotein (HDL) cholesterol in human blood when the milk is consumed. In addition, the properties of the milk fat during industrial milk processing are weakened. A high level of polyunsaturated fatty acids in milk can also cause taste defects and preservation problems. A typical fatty acid composition of milk fat may contain more than 70% saturated fatty acids and total amount of trans fatty acids may vary in the range of 3%-10%. When vegetable oil is added into the feed, the proportion of trans fatty acids may rise to more than 10%.

[0018] One solution to diminishing the detrimental effect of oil and fat is to prevent triglyceride fat hydrolysis. Fat hydrolysis can be decreased, for example, by protecting fats with formaldehyde treated casein. Another alternative is to make insoluble fatty acid calcium salts whereby hydrogenation in rumen can be avoided. However, fatty acid salts have a pungent taste, which can limit their usability in feeds and can result in decreased feed intake. The salts may also impact the pelletizing process of the feed.

[0019] Accordingly, the dietary composition described herein allows for the transfer of palmitic acid from the feed via the digestive tract into the blood circulation of a ruminant. This improves the energy efficiency of milk production of the ruminant. When the utilization of energy becomes more efficient, the milk production increases and the concentrations of protein and fat in the milk rise. Especially, the dietary composition enhances fat synthesis in the mammary gland by bringing milk fat components to the cell and therefore the energy consuming synthesis in the mammary gland is not necessary. Thus, glucose can more efficiently be used for lactose production whereupon milk production increases. The milk protein content rises since there is no need to produce glucose from amino acids. Thus, the ruminant therefore does not lose weight at the beginning of the lactation period.

[0020] In the various embodiments described herein, the dietary paste compositions may include at least one saturated fatty acid compound and at least one carrier component. The saturated fatty acid compound may be primarily one or more palmitic acid compounds, as described in greater detail herein. The saturated fatty acid compound may be about 10% to about 90% by weight of the dietary paste composition. In some embodiments, the dietary paste compositions described herein may be used as a booster or a supplement for ruminant feed.

[0021] FIG. 1 depicts a flow diagram of a method of preparing a dietary composition for consumption by a ruminant. In various embodiments, the dietary composition may be formulated in a manner so that when consumed by the ruminant, the dietary composition maximizes particular qualities in the milk produced by the ruminant, as well as an amount of milk produced by the ruminant, as described in greater detail herein. In particular embodiments, the dietary composition may be substantially a dietary paste composition. Thus, the terms "dietary composition" and "dietary paste composition" will be used interchangeably herein. [0022] In various embodiments, the components described herein with respect to FIG. 1 may generally be combined in any order and/or any combination, and are not limited by the order described herein. In some embodiments, a dietary composition may be prepared by heating 105 a saturated fatty acid, contacting 110 the saturated fatty acid with a carrier, and adding 115 one or more additional ingredients. In some embodiments, the saturated fatty acid may be heated 105 to a temperature that is equivalent to at least its melting point, as described in greater detail herein. Heating 105 the saturated fatty acid and adding 115 additional ingredients may be completed as optional processes. In addition, processes 105, 110, 115 may be performed in different orders, or both may be performed simultaneously. Furthermore, heating 105 may include heating the saturated fatty acid, the carrier, the one or more additional ingredients, or combinations thereof.

Because stearic acid in large amounts may hinder milk production capacity of the mammary gland, the amount of stearic acid may be present in the saturated fatty acid compound in an amount of about 30% or less by weight of the saturated fatty acid compound. In particular embodiments, the stearic acid compound may include about 30% by weight of the saturated fatty acid compound, about 25% by weight of the saturated fatty acid compound, about 20% by weight of the saturated fatty acid compound, about 15% by weight of the saturated fatty acid compound, about 10% by weight of the saturated fatty acid compound, about 5% by weight of the saturated fatty acid compound, or any value or range between any two of these values.

[0033] In various embodiments, a molar ratio of the palmitic acid compound to the stearic acid compound may be present in the saturated fatty acid compound. Illustrative molar ratios of the palmitic acid compound to the stearic acid compound in the saturated fatty acid compound may include about 2: 1, about 5: 1, about 10: 1, or any value or range between any two of these values. [0034] In some embodiments, the dietary composition may include an unsaturated fatty acid as an additional ingredient, as described herein.

For example, derivatives of an unsaturated fatty acid may include salts, esters, amides, anhydrides, alcohols, and/or the like, as previously described herein. In various embodiments, a minimal amount of unsaturated fatty acid in the saturated fatty acid compound to affect a desired quality of milk produced by the ruminant consuming the dietary composition may be used, as described in greater detail herein. Thus, in some embodiments, the dietary composition may substantially not include an unsaturated fatty acid. As used herein with respect to unsaturated fatty acids, the term "substantially free" is understood to mean substantially no amount of unsaturated fatty acids or about 5% or less by weight of unsaturated fatty acids, including trace amounts of unsaturated fatty acids. Accordingly, the unsaturated fatty acid may be present in the dietary composition in an amount of about 5% or less by weight of the saturated fatty acid compound, including about 5% by weight, about 4% by weight, about 3% by weight, about 2% by weight, about 1% by weight, about 0.5% by weight, about 0% by weight, or any value or range between any two of these values.

[0035] In various embodiments, at least a portion of the saturated fatty acid compound may be contained. In some embodiments, the saturated fatty acid compound may be pre-contained prior to contacting 110 the saturated fatty acid compound to the feed ingredient. In other embodiments, the saturated fatty acid compound may be contained as a result of the various processes 105, 110, 115 described herein. In some embodiments, the saturated fatty acid compound may generally be contained by at least one supermolecular structure. Supermolecular structures may include vesicular structures such as microemulsions, liposomes (vesicles), micelles, and reverse micelles. The liposomes (vesicles) may contain an aqueous volume that is entirely enclosed by a membrane composed of lipid molecules, such as phospholipids. In some embodiments, the liposomes may have a bilayer membrane. In some embodiments, the liposomes may include at least one surfactant. Examples of surfactants may include polyoxyethylene ethers and esters of fatty acids. The surfactant may have an hydrophilic-lipophilic balance (HLB) value of about 2 to about 12, including about 2, about 3, about 4, about 5, about 6, about 7, about 8, about 9, about 10, about 11, about 12, or any range or value between any two of these values. Micelles and reverse micelles are microscopic vesicles that contain amphipathic constituents but do not contain an aqueous volume that is entirely enclosed by a membrane. In micelles, the hydrophilic part of the amphipathic compound is on the outside (on the surface of the vesicle). In reverse micelles, the hydrophobic part of the amphipathic compound is on the outside. The reverse micelles may thus contain a polar core that can solubilize both water and macromolecules within the inverse micelle. As the volume of the core aqueous pool increases, the aqueous environment begins to match the physical and chemical characteristics of bulk water. The resulting inverse micelle may be referred to as a microemulsion of water in oil.

[0036] In some embodiments, at least a portion of the saturated fatty acid component may be contained in a core of a micelle or a vesicle. The core may include any number of particles therein in addition to the fatty acid. The core composition may be made of a core material that includes at least one of the protein material, the cellulosic material, the amino acid, and the amino acid derivative, as described in greater detail herein.

In some embodiments, additional ingredients may be added 215, as described in greater detail herein. In some embodiments, the colloid may be an emulsion, a suspension, or a combination thereof.

[0056] In various embodiments, water may be included in an amount that is separate from any amounts of water that may be inherently present in any of the other ingredients described herein. Water may generally be present in the dietary composition in an amount that is about 12% or less by weight, including about 0.5% by weight, about 1% by weight, about 2% by weight, about 3% by weight, about 5% by weight, about 8% by weight, about 10% by weight, about 12% by weight, or any value or range between any two of these values. [0057] In some embodiments, the dietary composition may be dried. Drying may generally be completed to remove any excess water or other undesired materials, as well as to provide a material that is suitable for use as a dietary paste composition.

[0058] In various embodiments, a method of increasing milk fat content in ruminants may include providing the dietary composition as described herein to the ruminant for ingestion. In some embodiments, milk may be obtained from the ruminant. In some embodiments, the dietary composition may be provided as a supplement or a booster. In particular embodiments, the dietary composition may be a dietary paste composition, as described in greater detail herein. In some embodiments, the composition may be admixed with feed to be provided to the ruminant. In some embodiments, the composition may be coated on the feed to be provided to the ruminant. In some embodiments, the dietary composition may be provided to the ruminant in an amount that the ruminant receives at least about 10 grams of fatty acid per kilogram of milk produced by the ruminant each day. The amount may be based on the previous day's milk production by the ruminant, an average day based on the previous week' s milk production by the ruminant, an average day based on the previous month's milk production by the ruminant, an average production of milk by the ruminant when not provided the dietary composition, and/or the like. In some embodiments, the ruminant may be provided with additional amounts of the dietary composition to make up for portions of the dietary composition that are not consumed by the ruminant such as amounts that are spilled by the ruminant when consuming the dietary composition and/or the like.

[0059] In some embodiments, providing the dietary composition to the ruminant for the ruminant to consume may result in an increase in production of milk and/or an increase in fat content of the milk produced. These increases may generally be relative to a similar ruminant that does not receive the dietary composition, an average of similar ruminants not receiving the dietary composition, an average of the milk production quantity and fat content of the same ruminant when not provided the dietary composition, and/or the like. In particular embodiments, the milk production may increase by an amount of about 1% to about 10%, including about 1%, about 2%, about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, or any value or range between any two of these values. In particular embodiments, the milk fat content may increase by an amount of about 10% to about 15%, including about 10%, about 11%, about 12%, about 13%, about 14%, about 15%, or any value or range between any two of these values.

[0060] Various portions of the components described herein may be ground to a particular particle size. Grinding may be performed by various grinding devices known to those having ordinary skill in the art, such as a hammer mill, a roller mill, a disk mill, or the like. The various components described herein may be ground to various sizes, such as particle size (for instance, measured in millimeters), mesh sizes, surface areas, or the like. According to some embodiments, the components may be ground to an average particle size of about 0.05 mm to about 10 mm. More particularly, the various components may be ground to produce a granular material having an average particle size of about 0.05 mm, about 0.1 mm, about 0.2 mm, about 0.5 mm, about 1.0 mm, about 2.0 mm, about 3.0 mm, about 4.0 mm, about 5.0 mm, about 6.0 mm, about 7.0 mm, about 8.0 mm, about 9.0 mm, about 10.0 mm, or any value or range between any two of these values. In some embodiments, the various components may be ground so that about 20% to 50% of the each component and/or all components are retained by a mesh having openings with a size of about 10 mm and so that about 70% to about 90% of each component and/or all components are retained by a mesh having openings with a size of about 1 mm. In some embodiments, the various components may have a varying distribution of particle sizes based upon the ingredients. For example, in embodiments containing one or more wheat ingredients, the particle size may be distributed so that about 95% of the ground wheat ingredients are retained by a mesh having openings with a size of about 0.0625 mm and so that about 65% of the ground wheat ingredients are retained by a mesh having openings with a size of about 1.0 mm. In another example, such as embodiments containing one or more barley ingredients, the particle size may be distributed so that about 95% of the ground barley ingredients are retained by a mesh having openings with a size of about 0.0625 mm and so that about 60% of the ground barley ingredients are retained by a mesh having openings with a size of about 1.0 mm. The varying mesh sizes of each ingredient may be independent of mesh sizes for other ingredients.

[0061] Grinding may provide various benefits, such as improving certain characteristics of the mineral lick mixture and/or the mineral lick composition formed therefrom. For instance, even and fine particle size may improve the mixing of different ingredients. According to certain embodiments, grinding may be configured to decrease a particle size of certain components of the mineral lick composition, for example, to increase the surface area open for enzymes in the gastrointestinal tract, which may improve the digestibility of nutrients, and/or to increase the palatability of the feed.

EXAMPLES

Example 1 : Making a Dietary Paste Composition

[0062] A dietary paste composition to be used as a feed booster for ruminant feed is made using a process of contacting at least one saturated fatty acid with at least one carrier component. The saturated fatty acid compound is at least about 50% by weight of the dietary paste composition. The saturated fatty acid compound includes about 98% by weight of a palmitic acid compound and about 2% by weight of a stearic acid compound. The carrier component includes starch, agar, and dried blood meal. The dietary paste composition also includes about 10% by weight of water and about 10% by weight of a nutritive component to include additional nutrients not currently present and/or lacking in the ruminant's current feed. The nutritive component includes molasses, glycerol, propane diol, vitamin A, riboflavin, pantothenic acid, folic acid, vitamin D, vitamin E, carnitine, a lysine derivative, calcium, iron, selenium, oat hulls, hay meal, and straw.

Example 2: Feeding a Dairy Cow

[0063] A dairy cow that has a normal (untreated) average daily production of 25 kg milk is provided with the dietary paste composition described above with respect to Example 1 to increase the milk fat and the quantity of the milk produced.

[0064] The dairy cow is given about 275 grams of dietary paste composition as an additive to the cow's daily TMR feed. This amount is selected to ensure that the cow consumes at least about 245 grams of the dietary paste composition over the course of a day. This amount corresponds to about 10 grams of palmitic acid for every kilogram of milk that the cow will produce that day. As a result, the cow produces 10% more milk than the cow did previously, and the milk that the cow produces contains 15% more milk fat content than the milk that the cow produced previously.

Example 3: Providing to a Large Group of Cows

[0065] The dietary paste composition as described above with respect to Example 1 is provided to a large group of cows on a commercial dairy farm to confirm its effectiveness. 1000 dairy cows from the commercial dairy farm are selected at random to provide a wide variation in various characteristics, such as breed, weight, age of the cow, and the like. The 1000 cows are equally divided into two groups: a sample cow group and a control cow group. Each day, the sample cow group is given the dietary paste composition in addition to the cow's TMR feed. In contrast, the control cow group only receives the regular TMR feed daily. The 1000 cows are monitored for the amount of mineral lick composition consumed, changes in weight, an amount of milk the cow produces each day, and the composition of the milk produced by the cow each day. Monitoring continues for a period of 90 days. A comparison of the two groups of cows over this period of time shows a statistically significant improvement from the group that consumed the dietary paste composition over the control group that did not receive the dietary paste composition.

Example 4: Fatty Acid Composition

[0066] The following table describes a fatty acid composition that increases the volume of milk produced by a ruminant and the milk fat content of the milk produced by the ruminant.

[0067] In the above detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be used, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein. [0068] The present disclosure is not to be limited in terms of the particular embodiments described in this application, which are intended as illustrations of various aspects. Many modifications and variations can be made without departing from its spirit and scope, as will be apparent to those skilled in the art. Functionally equivalent methods and apparatuses within the scope of the disclosure, in addition to those enumerated herein, will be apparent to those skilled in the art from the foregoing descriptions. Such modifications and variations are intended to fall within the scope of the appended claims. The present disclosure is to be limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled. It is to be understood that this disclosure is not limited to particular methods, reagents, compounds, compositions or biological systems, which can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.

[0069] With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

[0070] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (for example, bodies of the appended claims) are generally intended as "open" terms (for example, the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," et cetera). While various compositions, methods, and devices are described in terms of "comprising" various components or steps (interpreted as meaning "including, but not limited to"), the compositions, methods, and devices can also "consist essentially of or "consist of the various components and steps, and such terminology should be interpreted as defining essentially closed-member groups. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (for example, "a" and/or "an" should be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (for example, the bare recitation of "two recitations," without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, et cetera" is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (for example, " a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, et cetera). In those instances where a convention analogous to "at least one of A, B, or C, et cetera" is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (for example, " a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, et cetera). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."

[0071] In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

[0072] As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, et cetera As a non- limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, et cetera As will also be understood by one skilled in the art all language such as "up to," "at least," and the like include the number recited and refer to ranges which can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 cells refers to groups having 1, 2, or 3 cells. Similarly, a group having 1-5 cells refers to groups having 1, 2, 3, 4, or 5 cells, and so forth.

[0073] Various of the above-disclosed and other features and functions, or alternatives thereof, may be combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art, each of which is also intended to be encompassed by the disclosed embodiments.
