[0101] This invention relates to a method and system for determining the oral care performance of coarse abrasives in pet food (also referred to as "coarse abrasives only"). The method includes predicting the dental therapeutic and cleaning effects of the coarse abrasives on a pet's oral cavity during chewing.

[0102] Predictive determination involves analyzing the sample coarse abrasive and comparing it with a reference coarse abrasive whose properties were previously established to predict how the sample coarse abrasive will perform processing and / or cleaning effects during chewing.

[0103] The analysis includes the evaluation of numerous sample coarse abrasive properties. These properties may include, but are not limited to, coarse abrasive size, peak force, and contact time. For the reference sample coarse abrasive, these properties may be referred to as sample coarse abrasive size, sample coarse abrasive peak force, and sample coarse abrasive contact time.

In relation to the reference coarse abrasive, the reference coarse abrasive characteristics may be referred to as reference coarse abrasive size, reference coarse abrasive peak force, and reference coarse abrasive contact time. As used herein, contact time is typically determined using a texture analyzer, and a screwdriver blade is used to simulate teeth, whereby the texture analyzer pushes the screwdriver blade across the coarse abrasive and quantifies the force as a function of time. The contact time is then determined as the width of the force versus time curve at one-quarter of the height (see [link to relevant documentation]). Figure 13A and Figure 13B In at least one embodiment, the contact time is defined as the peak width of the force-time curve at one-quarter of the height (see [reference]).

In some embodiments, the model can compare the peak force of the sample coarse abrasive with that of a reference coarse abrasive; the size of the sample coarse abrasive with that of a reference coarse abrasive; and the contact time of the sample coarse abrasive with that of a reference contact time.

[0107] The reference roughing material size can range from the minimum reference size to the maximum reference size. The minimum and maximum reference sizes are not equal. The minimum reference size is smaller than the maximum reference size.

[0108] The reference coarse abrasive can be any size suitable as a coarse abrasive for pet food. In other words, the predictive determination of the present invention based on comparing the characteristics of a reference coarse abrasive with those of a sample coarse abrasive can be unrestricted by the specific coarse abrasive sizes (including coarse abrasive volume, shape, etc.) of the sample and reference coarse abrasives.

The minimum reference peak force and the maximum reference peak force are not equal. The minimum reference peak force is less than the maximum reference peak force.

[0114] The reference coarse abrasive can be any coarse abrasive suitable as a pet food for peak force. In other words, the predictive determination of the present invention, based on comparing the characteristics of a reference coarse abrasive with those of a sample coarse abrasive, is not limited to the specific peak forces of the sample and reference coarse abrasives.

[0115] In a non-limiting embodiment, the minimum peak force of the reference coarse abrasive may be about 2,000 (g), and the maximum peak force of the reference coarse abrasive may be about 24,000 (g). In some embodiments, the reference coarse abrasive may have a peak force greater than 24,000 (g). In some embodiments, the reference coarse abrasive has a peak force less than 2,000 (g).

[0116] In a non-limiting embodiment, the minimum peak force of the reference coarse abrasive may be about 4,000 (g), and the maximum peak force of the reference coarse abrasive may be about 20,000 (g). The range of peak forces of the reference coarse abrasive may be between about 4,000 (g) and about 20,000 (g)—inclusive of any forces and subranges therein.

[0117] In a non-limiting embodiment, the minimum peak force of the sample coarse abrasive can be about 2,000 (g), and the maximum peak force of the sample coarse abrasive can be about 24,000 (g). In some embodiments, the sample coarse abrasive can have a peak force greater than 24,000 (g). In some embodiments, the sample coarse abrasive has a peak force less than 2,000 (g).

[0118] In a non-limiting embodiment, the minimum peak force of the sample coarse abrasive can be about 4,000 (g), and the maximum peak force of the sample coarse abrasive can be about 20,000 (g). The range of peak forces of the sample coarse abrasive can be between about 4,000 (g) and about 20,000 (g)—inclusive of any forces and subranges therein.

[0119] The coarse abrasive texture analysis of this invention refers to how a sample coarse abrasive will remain together during in vitro puncture. In a non-limiting example, a handheld tool (such as a screwdriver blade) can be used to simulate teeth, while the texture analyzer pushes it across the sample coarse abrasive and quantifies the force as a function of time—as shown graphically in Figure 13, the contact time is defined here as the width of the force curve generated by the instrument at a quarter-height position. Thus, the contact time can be the time span during which the applied force is measured.

[0120] These values ​​can then be compared with known reference coarse abrasives that have undergone the same analysis, revealing how effective these reference coarse abrasives are at cleaning / treating the pet's mouth during chewing. This process provides a meaningful mechanism for testing and analyzing coarse abrasives in vitro without the need for in vivo studies.

[0121] Peak force is defined as the maximum force applied to the coarse abrasive by a texture analyzer. Peak force can be measured in vitro using a texture analyzer. Peak force of a reference coarse abrasive can be measured in vitro using a texture analyzer. Peak force of a sample coarse abrasive can be measured in vitro using a texture analyzer. While peak force relates to how the pet's mouth can penetrate or crush the coarse abrasive during chewing, measuring these properties in vitro allows for accurate collection of coarse abrasive characteristics that might otherwise be difficult to measure in in vivo methods (e.g., measuring force in some way while the pet is chewing the coarse abrasive).

[0122] For the analysis, contact time, peak force, and coarse abrasive size were estimated, and data from a reference coarse abrasive study were combined to attempt to correlate mechanically derived dental effects with coarse abrasive texture. Dental effect data from the Logan / Boyce test method were used in conjunction with coarse texture indices to estimate coarse abrasive texture and its relationship with the ability of food to reduce dental plaque, tartar (dental stains), stains, gingivitis, and halitosis in small breed dogs. Dental endpoints were the Logan / Boyce scores for plaque, tartar, stains, gingivitis, and halitosis, and the percentage reduction in these parameters compared to a control (non-dental) food (defined as dental effect).

[0123] Plaque effect, tartar effect, gingivitis effect, and odor effect are defined as the percentage reduction in the measured endpoint score for the assessed characteristic: (Control) / Control x 100%. In some embodiments, the method includes determining a mathematical formula representing the correlation between plaque effect, tartar effect, gingivitis effect, or odor effect and contact time. For example, the method may include using regression analysis to determine a mathematical formula representing the correlation between plaque effect, tartar effect, gingivitis effect, or odor effect and contact time.

[0124] In some preferred embodiments, the method includes estimating and / or determining plaque effectiveness using the following equation: Plaque effectiveness (%) = 30.33 × one or more contact times - 46.88.

[0125] In some preferred embodiments, the method includes estimating and / or determining the odor effect using the following equation: Odor effect (%) = 0.002194 × size - 1.817.

[0126] In some preferred embodiments, the method includes estimating and / or determining the gingivitis effect using the following equation: Gingivitis effect (%) = 0.002503 × size - 2.339.

[0127] In some preferred embodiments, the method includes estimating and / or determining the tartar effect using the following equation: Tartar effect (%) = 0.006660 × size + 3.492.

[0128] In some preferred embodiments, the method includes estimating and / or determining the plaque effect using the following equation: Plaque effect (%) = 0.007063 × size - 13.39.

[0129] In some preferred embodiments, the method includes estimating the gingivitis effect using the following equation: Gingivitis effect (%) = 0.000913 × peak force - 3.618.

[0130] In some preferred embodiments, the method includes estimating and / or determining the tartar effect using the following equation: Tartar effect (%) = 0.002729 × peak force - 4.028.

[0131] In some preferred embodiments, the method includes estimating and / or determining plaque effectiveness using the following equation: Plaque effectiveness (%) = 0.003104 × peak force - 24.24.

[0132] In some preferred embodiments, the method includes estimating the odor effect using the following equation: Odor effect (%) = 0.001056 × peak power - 5.896.

[0133] In some preferred embodiments, the method includes estimating and / or determining the gingivitis effect using the following equation: Gingivitis effect (%) = 11.7 × contact time - 16.07.

[0134] In some preferred embodiments, the method includes estimating and / or determining the tartar effect using the following equation: Tartar effect (%) = 27.28 × contact time - 24.83.

[0135] In some preferred embodiments, the method includes estimating and / or determining the odor effect using the following equation: Odor effect (%) = 9.138 × contact time - 11.25.

[0136] This method may include using any of the aforementioned correlations and / or mathematical formulas to estimate and / or ultimately determine the odor effect, tartar effect, gingivitis effect, and / or plaque effect. The method of the present invention may also include a step of creating output values ​​based on comparisons performed by a model. The output values ​​may be a predictive determination of whether a sample coarse abrasive will meet a minimum threshold for oral care performance (i.e., improve the pet's oral health).

[0137] In some embodiments, the sample coarse abrasive size is greater than a minimum reference size when the output value can predict that the sample coarse abrasive meets a minimum threshold for treating oral conditions in pets during consumption of the sample coarse abrasive.

[0138] In some embodiments, when the output value predicts that the sample pet food coarse abrasive meets the minimum threshold for treating oral conditions in pets during the consumption of the sample pet food coarse abrasive, the peak force of the sample coarse abrasive is greater than the minimum reference peak force.

[0139] Non-limiting examples of improving such pet oral health could be reducing and / or eliminating plaque, tartar, gingivitis, odor, stains, etc.

[0140] Reference coarse abrasive properties can be collected from known coarse abrasive materials. These properties can be stored in a database. The reference coarse abrasive properties can be accessed from the database and combined with newly collected sample coarse abrasive properties before being incorporated into the model.

[0141] The sample coarse abrasive can be a coarse abrasive with a new formulation, size, shape, texture, etc. Using the model of this invention, in vitro methods can be used to predict the therapeutic effects on pet oral health during chewing of the new coarse abrasive (i.e., the sample coarse abrasive). This finding is valuable because it provides a new approach to coarse abrasive design when the goal is to achieve a coarse abrasive that can improve pet oral health during chewing without the need for in vivo studies.

[0142] Pet food compositions (also known as "pet food") are typically in coarsely ground form. Pet food compositions according to the present invention may include a variety of ingredients, including but not limited to fiber, protein, carbohydrates, and fat.

[0143] Pet food compositions may include a variety of ingredients, including but not limited to fiber, protein, carbohydrates, and fat. Protein can be provided from any of a variety of sources known to those skilled in the art, including plant-based, animal-based, or both. Animal-based sources of protein include, for example, meat, meat by-products, seafood, dairy products, eggs, etc. Meat includes, for example, the meat of poultry, fish, and mammals (e.g., beef, pork, sheep, goat, etc.).

In a preferred embodiment, the protein content in the coarsely ground material can range from about 25 wt.% to about 35 wt.%—inclusive of all percentages and sub-ranges therein—based on the total weight of the coarsely ground material.

[0147] Fats can be provided from any of a variety of sources known to those skilled in the art, including meat, meat by-products, fish oil, and plants. Plant fat sources include wheat, flaxseed, rye, barley, rice, sorghum, corn, oats, millet, wheat germ, corn germ, soybeans, peanuts, and cottonseed, as well as oils derived from these and other plant fat sources. Meat fat sources include beef, pork, and poultry fat. Fats can be crude fat.

[0148] Non-limiting examples of fats include animal fats and plant-based fats. In one respect, fat sources can be animal fat sources, such as beef tallow or poultry fat. Plant-based oils, such as corn oil, sunflower oil, safflower oil, grapeseed oil, soybean oil, olive oil, and other oils rich in monounsaturated and polyunsaturated fatty acids, can also be used.

[0149] In a non-limiting embodiment, the fat content in the food composition may range from about 10 wt.% to about 30 wt.%—inclusive of all percentages and sub-ranges therein—based on the total weight of the food composition. In a preferred embodiment, the fat content in the food composition may range from about 15 wt.% to about 25 wt.%—inclusive of all percentages and sub-ranges therein—based on the total weight of the food composition.

[0150] In a non-limiting embodiment, the fat content in the coarsely ground material can range from about 10 wt.% to about 30 wt.%—inclusive of all percentages and sub-ranges therein—based on the total weight of the coarsely ground material. In a preferred embodiment, the fat content in the coarsely ground material can range from about 15 wt.% to about 25 wt.%—inclusive of all percentages and sub-ranges therein—based on the total weight of the coarsely ground material.

[0151] Carbohydrates can be provided from any of a variety of sources known to those skilled in the art, including oat fiber, cellulose, peanut shells, beet pulp, semi-cooked rice (white and / or brown), corn starch, corn gluten meal, and any combination of these sources. Cereals that provide carbohydrates include, but are not limited to, wheat, corn, barley, and rice. The carbohydrate content of a food can be determined by any number of methods known to those skilled in the art.

[0152] Non-limiting examples of carbohydrate sources include cereals or grains such as rice, corn, millet, sorghum, alfalfa, barley, soybeans, rapeseed, oats, wheat, rye, triticale, and mixtures thereof. The composition may also optionally include other materials such as dried whey and other dairy byproducts.

[0153] In a non-limiting embodiment, the carbohydrate content in the food composition may range from about 25 wt.% to about 55 wt.%—inclusive of all percentages and sub-ranges therein—based on the total weight of the food composition. In a preferred embodiment, the carbohydrate content in the food composition may range from about 35 wt.% to about 45 wt.%—inclusive of all percentages and sub-ranges therein—based on the total weight of the food composition.

In a preferred embodiment, the carbohydrate content in the coarsely ground material can range from about 35 wt.% to about 45 wt.%—inclusive of all percentages and sub-ranges therein—based on the total weight of the coarsely ground material.

[0155] The food composition may also include one or more fiber sources. The fibers of the present invention may be one or more fibers selected from oriented fibers, dietary fibers, fermentable fibers, non-fermentable fibers, coarse fibers, and neutral detergent fibers. Whether digestible or indigestible, soluble or insoluble, the fiber can provide volume in the food composition. According to the present invention, the food composition may include total fiber contents—this may refer to all fiber components (i.e., a combination of oriented and non-oriented fibers).

[0156] Based on the total weight of the food composition, the total fiber content in the food composition can range from about 3 wt.% to about 30 wt.%—inclusive of all percentages and subranges therein.

[0157] In a non-limiting embodiment, the total fiber content in the coarse mill can range from about 3 wt.% to about 30 wt.%—inclusive of all percentages and subranges therein—based on the total weight of the coarse mill.

[0158] In a non-limiting embodiment, based on the total weight of the food composition, the food composition may include oriented fibers in a content ranging from about 3 wt.% to about 30 wt.%—including all percentages and subranges therein.

[0159] In a non-limiting embodiment, the content of oriented fibers in the coarse abrasive can range from about 3 wt.% to about 30 wt.%—inclusive of all percentages and subranges therein—based on the total weight of the coarse abrasive.

[0160] The term "oriented fiber" can refer to a coarsely ground material formed such that the fibrous component has the same orientation (i.e., coarsely ground material) within a reference composition. Fibers can be oriented using the method disclosed in U.S. Patent No. 5,500,239, the entire contents of which are incorporated herein by reference for all purposes. The amount of oriented fiber can be determined using X-ray microscopy. In a non-limiting example, this orientation can be achieved using a heated extruder having one or more transfer screws within a closed, heated barrel and a restricted extrusion discharge channel, such as a die, nozzle, or pipe, at the front end of the barrel. A mixture formed from the fibrous component with one or more combinations of carbohydrates, proteins, and fats can be pretreated and moistened with steam and water, and then plasticized in the extruder barrel under a combination of temperature, shear, and pressure, thereby transforming the feed mixture into a flowable substance. The advancing substance generates sufficient shear force to push the plasticized mixture through the discharge channel at the desired temperature and pressure.

[0161] For example, when in coarsely ground form, the water content of the pet food composition can range from about 4 wt.% to about 16 wt.% based on the total weight of the pet food composition. In some embodiments, the water content of the pet food composition, based on the total weight of the composition, can range from about 4 wt.% to about 16 wt.%, about 4 wt.% to about 13 wt.%, about 4 wt.% to about 11 wt.%, about 4 wt.% to about 9 wt.%, about 4 wt.% to about 7 wt.%; about 6 wt.% to about 16 wt.%, about 6 wt.% to about 13 wt.%, about 6 wt.% to about 11 wt.%, about 6 wt.% to about 9 wt.%; about 8 wt.% to about 16 wt.%, about 8 wt.% to about 13 wt.%, about 8 wt.% to about 11 wt.%, about 10 wt.% to about 16 wt.%, about 10 wt.% to about 13 wt.%, or any range or subrange thereof.

[0162] Subsequently, the plasticized mixture can enter the discharge channel from the transfer screw, where it is compressed and heated to a sufficiently high temperature so that the mixture is cooked as it flows through the discharge channel. During the passage of the plasticized mixture through the discharge channel, the flow conditions in the extruder are considered to be close to laminar flow due to the low coefficient of friction of the inner wall.

[0163] Laminar flow differs from turbulent flow, which is the normal flow condition for extruding plasticized animal food products. In turbulent flow, fluid elements are in chaotic motion, and even if the average velocity can remain constant along its axis, there will be small random fluctuations in velocity at a single point. Laminar flow is a flow with constant streamlines, which allows constant velocity surfaces to maintain constant separation, and thin layers or sheets of fluid can slide against each other without friction. By creating laminar-like conditions during product extrusion, the fibrous components in the mixture can be oriented in transverse striations within the product matrix. In contrast, fibrous food products extruded under turbulent conditions contain fibrous materials randomly distributed throughout the food product. When chewed by an animal, this food product crumbles rather than breaks, and exerts a limited mechanical cleaning effect on the animal's teeth.

[0164] During extrusion, the moisture in the extrudate is in a superheated state, and when the extrudate leaving the discharge channel is suddenly depressurized, the moisture will flash into steam. The escaping steam will cause the extrudate to expand and grow. The extrudate leaves the discharge channel in the form of coarse strands, ready to be cut into small balls, etc.

[0165] The extrusion can then be formed into a coarse abrasive. This coarse abrasive can be a solid, homogeneous, expanded composition with fibrous striations extending laterally through the matrix microstructure. Unlike baked or other extruded products, this food product does not crumble when chewed by an animal; instead, it breaks along the matrix striations, thus providing the animal with the intended dental cleaning benefits derived from mechanical cleaning and other abrasive contact with the matrix layer separated from the chewed striations—thereby treating oral problems in pets. Furthermore, because the striationed fibrous product does not crumble when chewed by the animal, it adheres and bonds to the teeth for an extended period, thus prolonging the mechanical dental cleaning effect.

[0166] Dietary fiber refers to the components of plants that resist digestion by animal digestive enzymes. Non-limiting examples of fiber include fiber from plant sources (such as marine plants), but fiber from microbial sources can also be used. As is known to those skilled in the art, a variety of soluble or insoluble fibers can be utilized. Fiber sources can include beet pulp (from beets), gum arabic, tarharzianum, psyllium husk, rice bran, carob gum, citrus pulp, pectin, fructooligosaccharides, short-chain fructooligosaccharides, mannan-fructooligosaccharides, soybean fiber, arabinogalactan, galactooligosaccharides, arabinoxylan, or mixtures thereof.

[0167] In non-limiting embodiments, the dietary fiber content in the food composition can range from about 2 wt.% to about 10 wt.% based on the total weight of the food composition—inclusive of all percentages and sub-ranges therein.

[0168] In a non-limiting embodiment, the dietary fiber content in the coarsely ground material can range from about 2 wt.% to about 10 wt.%—inclusive of all percentages and subranges therein—based on the total weight of the coarsely ground material.

[0169] Soluble fiber is not easily digested and absorbed in the small intestine and will be completely or partially fermented in the large intestine. Examples include beet pulp, guar gum, chicory root, psyllium, pectin, blueberries, cranberries, pumpkin, apples, oats, beans, citrus fruits, barley, or peas.

[0170] In non-limiting embodiments, the content of soluble fiber in the food composition can range from about 0.1 wt.% to about 3.0 wt.%—inclusive of all percentages and sub-ranges therein—based on the total weight of the food composition.

[0171] In a non-limiting embodiment, the content of soluble fibers in the coarse abrasive can range from about 0.1 wt.% to about 3.0 wt.%—inclusive of all percentages and subranges therein—based on the total weight of the coarse abrasive.

[0172] Insoluble fiber can be provided from any of a variety of sources, including cellulose, whole wheat products, oats, corn bran, flaxseed, grapes, celery, green beans, cauliflower, potato peels, fruit peels, vegetable peels, peanut shells, and soybean fiber.

[0173] In non-limiting embodiments, the content of insoluble fiber in the food composition can range from about 2.0 wt.% to about 8.0 wt.% based on the total weight of the food composition—inclusive of all percentages and sub-ranges therein.

[0174] In a non-limiting embodiment, the content of insoluble fibers in the coarse abrasive can range from about 2.0 wt.% to about 8.0 wt.%—inclusive of all percentages and subranges therein—based on the total weight of the coarse abrasive.

[0175] Crude fiber includes indigestible components contained in plant cell walls and cell contents, such as the outer shell of grains like rice, corn, and beans.

[0176] Based on the total weight of the food composition, the content of crude fiber in the food composition can range from about 0.5 wt.% to 3.0 wt.%—inclusive of all percentages and sub-ranges therein. In a non-limiting embodiment, based on the total weight of the coarsely ground material, the content of crude fiber in the coarsely ground material can range from about 0.5 wt.% to about 3.0 wt.%—inclusive of all percentages and sub-ranges therein.

[0177] Alternatively, the fiber source may be fermentable fiber. The benefits of fermentable fiber to the immune system of companion animals have been previously described. Fermentable fiber or other compositions known to those skilled in the art that provide probiotics to enhance the growth of probiotics in the gut may also be incorporated into the composition to help enhance the benefits of this invention to the animal's immune system.

[0178] Food compositions may also include ash. As described herein, ash consists of non-organic or non-aqueous compounds and is typically produced by the combustion of biological materials.

[0179] In non-limiting embodiments, the ash content in the food composition can range from about 1.0 wt.% to about 10.0 wt.%—inclusive of all contents and sub-ranges therein—based on the total weight of the food composition. In non-limiting embodiments, the ash content in the coarsely ground material can range from about 1.0 wt.% to about 10.0 wt.%—inclusive of all contents and sub-ranges therein—based on the total weight of the coarsely ground material.

[0180] The food compositions of the present invention may also include one or more amino acids. Essential amino acids vary by species and depend on the organism's metabolism. For example, the essential amino acids generally considered to be phenylalanine, leucine, methionine, lysine, isoleucine, valine, threonine, tryptophan, alanine, histidine, and arginine for dogs and cats (and humans) are phenylalanine, leucine, methionine, methionine, methionine, lysine, isoleucine, valine, threonine, tryptophan, alanine, histidine, and arginine. Furthermore, taurine, although technically not an amino acid but a derivative of cysteine, is an essential nutrient for cats. A balanced diet can provide all essential amino acids; however, there are certain more critical essential amino acids, as a diet lacking one of them limits the usefulness of the other essential amino acids, even if the other essential amino acids are present in sufficient quantities. Generally, these limiting amino acids are methionine, cysteine, tryptophan, and lysine.

[0181] The food compositions of the present invention may also include one or more minerals and / or trace elements, such as calcium, phosphorus, sodium, potassium, magnesium, manganese, copper, zinc, choline, or iron salts. A preferred trace element is manganese. Manganese is essential as a cofactor for many enzymes that regulate the metabolism of food, including proteins, fats, and carbohydrates. Such enzymes may include oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases, lectins, and integrins. Manganese also affects bone development and nerve function. Manganese may be naturally present in the composition or may be added to the composition.

[0182] In some embodiments, the food composition may also include the amounts of vitamins and minerals required to avoid deficiency and maintain health. These amounts and methods of measurement are known to those skilled in the art. For example, AAFCO provides recommended amounts of these ingredients for dogs and cats. As contemplated herein, beneficial vitamins may include, but are not limited to, vitamin A, vitamin B1, vitamin B2, vitamin B6, and vitamin B6. 12 Vitamins C, D, E, H (Biotin), K, folic acid, inositol, niacin, and pantothenic acid.

[0183] The food compositions of the present invention may further include additives, stabilizers, fillers, thickeners, flavoring agents, palatability enhancers and coloring agents, in amounts and combinations familiar to those skilled in the art.

[0184] The coarsely ground material of the present invention may further include additives, stabilizers, fillers, thickeners, flavoring agents, palatability enhancers and coloring agents, in amounts and combinations familiar to those skilled in the art.

[0185] In various embodiments, the food composition comprises at least one of the following: (1) one or more probiotics; (2) one or more inactivated probiotics; (3) one or more components of inactivated probiotics that promote similar or identical health benefits to the probiotics, such as proteins, lipids, glycoproteins, etc.; (4) one or more prebiotics; and (5) combinations thereof. Probiotics or components thereof may be incorporated into the food composition (e.g., uniformly or non-uniformly distributed within the composition) or applied to the food composition (e.g., locally applied with or without a carrier). Such methods are known to those skilled in the art, for example, by U.S. Patent No. 5,968,569 and related patents.

[0186] Typical probiotics include, but are not limited to, probiotic strains selected from lactobacilli, bifidobacteria, or enterococci, such as Lactobacillus reuteri, Lactobacillus acidophilus, Lactobacillus animalis, Lactobacillus rumeni, Lactobacillus johnsonii, Lactobacillus casei, Lactobacillus paracasei, Lactobacillus rhamnosus, Lactobacillus fermentum and Bifidobacterium spp., Enterococcus faecalis and Enterococcus spp. In some embodiments, the probiotic strain may be selected from the group consisting of: Lactobacillus reuteri (NCC2581; CNCM 1-2448), Lactobacillus reuteri (NCC2592; CNCM 1-2450), Lactobacillus rhamnosus (NCC2583; CNCM 1-2449), Lactobacillus reuteri (NCC2603; CNCM 1-2451), Lactobacillus reuteri (NCC2613; CNCM 1-2452), Lactobacillus acidophilus (NCC2628; CNCM 1-2453), Bifidobacterium adolescentis (e.g., NCC2627), Bifidobacterium spp. NCC2657, or Enterococcus faecalis SF68 (NCIMB10415). Many such probiotics and their benefits are known to those skilled in the art, such as EP1213970B1, EP1143806B1, U.S. Patent No. 7,189,390, EP1482811B1, EP1296565B1 and U.S. Patent No. 6,929,793.

[0187] As described above, the food composition may contain one or more prebiotics, such as fructooligosaccharides, glucose oligosaccharides, galactooligosaccharides, isomaltooligosaccharides, xylooligosaccharides, soybean oligosaccharides, lactulose oligosaccharides, lactulose, and isomaltulose. In one embodiment, the probiotic may be chicory root, chicory root extract, inulin, or a combination thereof. Generally, the amount of prebiotics applied is sufficient to actively stimulate the healthy microbial community in the gut and allow these “good” bacteria to multiply. Typical amounts range from about 1 to about 10 grams per serving, or about 5% to about 40% of the daily recommended dietary fiber for animals. Probiotics and prebiotics can be incorporated into the composition by any suitable method. Typically, these agents can be mixed with the composition or applied to the surface of the composition, for example, by sprinkling or spraying. When the agent is part of a kit, it can be mixed with other materials or packaged in its own packaging.

[0188] The coarse abrasive can have a coarse abrasive size range of approximately 800 mm. 3 To approximately 10,000 mm 3 —Including all volumes and sub-ranges therein. In a non-limiting embodiment, the abrasive may have a abrasive size range of approximately 1000 mm. 3 To approximately 8,000 mm 3 —Including all volumes and subranges within it.

[0189] It has been found that at this coarse abrasive size, when combined with oriented fibers, the resulting coarse abrasive slightly improves the resolution of pet oral problems by increasing the contact time between the coarse abrasive and the oral cavity during consumption.

[0190] In some embodiments, the food composition of the present invention may be in the form of pet food. In another embodiment, the food composition may be a snack.

In another aspect, dosing can be performed at least once a week. In some embodiments, more frequent dosing or consumption can be performed, such as twice or three times a week, or four times, or five times, or six or seven times a week. In one aspect, the dosing regimen can include consumption at least once a day. In one aspect, the dosing regimen can include periodic dosing, including every week, every two weeks, or every three weeks, or every month, or every two months, or every three months, every quarter, every quarter, every two quarters, every three quarters, etc.

[0193] When the kit includes a virtual package, the kit is limited to a combination of instructions in a virtual environment and one or more physical kit ingredients. The kit contains sufficient amounts of ingredients to promote lean body mass, reduce body fat gain, and / or manage weight.

[0198] Example

[0199] An experiment was prepared to measure the effects of certain properties of pet food compositions in coarse abrasive form, including coarse abrasive size and peak coarse abrasive force, on improving oral health in pets (i.e., reducing plaque, tartar, gingivitis, and odor) through contact time during consumption, coarse abrasive size, and peak force.

[0200] Each coarse abrasive was estimated to determine its dietary ability to alleviate dental plaque, tartar (dental plaque), gingivitis, and halitosis in dogs. Test and control values ​​for contact time, abrasive size, and peak force were collected for each coarse abrasive, along with corresponding efficacy values ​​for plaque, tartar, gingivitis, and halitosis removal. The control coarse abrasive size ranged from approximately 10¹⁴ mm. 3 Approximately 1030 mm 3The contact time was approximately 0.15 seconds, and the peak force was approximately 9285 g. The contact time was determined using a texture analyzer (Texture Technology TA.XTplus) to generate a force profile by pushing an alternative tooth (screwdriver blade) across a single coarse abrasive, while recording the force required for its entire journey. The generated force profile shows a function of force (Y-axis) versus time (X-axis), recording the magnitude of the force required to push the coarse abrasive, the degree to which the coarse abrasive remained together, and the duration of this process.

[0201] Calculate the overall effect for each coarse abrasive using the following formula:

[0202]

[0203] The results for each record are shown in the table below, starting with Table 1—for coarse abrasive sizes. Plaque effect, tartar effect, gingivitis effect, and odor effect were determined as the percentage reduction in the measured endpoint score of the assessed characteristic (control) / control x 100%.

[0204] Table 1

[0205]

[0206] Then plot the values ​​from Table 1 onto... Figure 1-4 The figures demonstrate a statistically significant relationship between the size and effectiveness of treatments for various oral problems. It should be noted that the term "NM" refers to the unmeasured value.

[0207] The recorded values ​​for peak force (g) are shown in Table 2 below.

[0208] Table 2

[0209]

[0210] Then plot the values ​​from Table 2 onto... Figure 5-8 The figure shows a statistically significant relationship between the size and effectiveness of treatments for various oral problems.

[0211] Table 3 lists the recorded values ​​for contact time (seconds).

[0212] Table 3

[0213]

[0214] Then plot the values ​​in Table 3 onto... Figure 9-12The graphs demonstrate a statistically significant relationship between the size and effectiveness of treatments for various oral problems. Statistical significance for effectiveness was determined using an unpaired, two-tailed Student's t-test in Microsoft Excel, where a p-value < 0.05 was considered statistically significant. Regression analysis was performed in GraphPad Prism using the effectiveness values ​​and values ​​for CT, PF, and KS, and the slope was tested to determine if it was distinct from zero. A p-value < 0.05 was considered statistically significant.

[0215] Based on the values ​​in Tables 1, 2, and 3, a model can be created to compare the characteristics of the sample coarse abrasive with the above reference values ​​to determine whether the sample coarse abrasive can effectively treat / remove plaque, tartar, gingivitis, and / or odor.
