Description:
FOOD COMPOSITIONS FOR COMPANION ANIMALS

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to European Patent Application No. 22200209.9, filed on October 7, 2022, which is incorporated herein by reference in its entirety.

FIELD OF THE DISCLOSURE

The present disclosure relates to the field of food compositions for companion animals, especially for puppies, and uses thereof.

BACKGROUND OF THE DISCLOSURE

Companion animals, such as dogs and cats, require differing diets depending on their age, size, body composition, medical problems and often breed. Both dog and cat nutrient requirements can be separated into three different categories based on the life stage which are: growing animals, such as puppies, adult animals, and senior animals.

Like human babies, the first years of an animal’s life are marked by rapid growth and development. Tissues and organs continue to form, develop, and mature into adult levels and functionalities. Therefore, companion animals during the growth, require adapted dietary compositions to support its energy needs and tissue-building requirements.

However, certain commercial diets indicated for growth can contain allergens that could cause adverse immune reactions and/or food intolerance in companion animals, especially in young animals, which are particularly susceptible.

This condition, also known as an adverse food reaction, is usually an abnormal response to animal and/or vegetal proteins found in commercial pet food leading to a resistance to feed of companion animals, especially puppies, with detrimental impacts on their health. Adverse food reactions can present dermatological lesions and/or gastrointestinal problems, such as vomiting or diarrhea, that can cause discomfort and pain in companion animals.

There are currently food compositions on the market supposed to be considered, or presented as, hypoallergenic, but none of them have been specifically designed to fulfill the specific requirement of a food for a young animal, particularly a puppy. It can be mentioned that, said requirements for a puppy food composition are considered, according to the current knowledge of the person skilled in the art, difficult to reconcile with the requirements of a hypoallergenic food composition.

Nevertheless, said food compositions do not provide effective nutritional content and contain animal proteins that can cause allergic reactions in companion animals that consume it.

Thus, there is a need for alternative hypoallergenic food compositions that promote and/or support the growth of a companion animal, in particular a puppy, for decreasing or minimizing the risk of adverse food reactions while remaining palatable.

There is a need for novel hypoallergenic food compositions for promoting and/or supporting the growth of a companion animal, in particular a puppy, especially for a companion animal suffering from adverse food reaction.

There is a need for novel hypoallergenic food compositions reducing the likelihood of occurrence of adverse food reactions in a companion animal, in particular a puppy.

In addition, novel hypoallergenic diets should be palatable, well tolerated and digested by the companion animal and be easily produced.

There is a need for novel hypoallergenic dry food compositions adapted to puppies, with such regard to the size and/or the texture of the dry food composition.

There is a need for novel hypoallergenic dry food compositions palatable for a companion animal, such as a puppy.

The present disclosure has for purpose to satisfy all or part of the above-mentioned needs.

SUMMARY OF THE DISCLOSURE

DETAILED DESCRIPTION OF THE DISCLOSURE

The objective of the present disclosure is to provide a well-tolerated new hypoallergenic dry food composition, including hydrolyzed vegetal protein, an optimal nutritional level of proteins, vitamins, calcium, phosphorus, threonine and/or fat for a companion animal, preferably a puppy, especially those susceptible or predisposed to adverse food reaction or those suffering from adverse food reaction.

The food composition as described herein does not provoke allergic reaction in companion animals. In particular, the food composition of the present disclosure is formulated to avoid or at least minimized the risk of a food aversion. For clarity and not by way of limitation, the detailed description of the presently disclosed subject matter is divided into the following subsections:

1. Definitions;

2. Hypoallergenic nutritionally complete dry food composition;

3. Method for manufacturing hypoallergenic nutritionally complete dry food composition; and

4. Uses of hypoallergenic nutritionally complete dry food compositions.

1. DEFINITIONS

The terms used in this specification generally have their ordinary meanings in the art, within the context of this subject matter and in the specific context where each term is used. Certain terms are defined below, or elsewhere in the specification, to provide additional guidance in describing the compositions and methods of the disclosed subject matter and how to make and use them.

As used in the specification and the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a compound” includes mixtures of compounds.

The terms “comprise(s),” “comprising”, “include(s),” “including”, “having,” “has,” “can,” “contain(s),” and variants thereof, as used herein, are intended to be open-ended transitional phrases, terms, or words that do not preclude the possibility of additional acts or structures. The present disclosure also contemplates other embodiments “comprising,” “consisting of,” and “consisting essentially of,” the embodiments or elements presented herein, whether explicitly set forth or not.

The term “about” means within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, z.e., the limitations of the measurement system. For example, “about” can mean a range of up to 10% of a given value. Also, particularly with respect to systems or processes, the term can mean within an order of magnitude, preferably within two-fold of a value.

Ranges provided herein are understood to be shorthand for all of the values within the range. For example, a range of 1 to 50 is understood to include any number, combination of numbers, or sub-range from the group consisting 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 as well as all intervening decimal values between the aforementioned integers such as, for example, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, and 1.9. Ranges disclosed herein, for example, “between about X and about Y” are, unless specified otherwise, inclusive of range limits about X and about Y as well as X and Y. With respect to sub-ranges, “nested sub-ranges” that extend from either endpoint of the range are specifically contemplated. For example, a nested sub-range of an exemplary range of 1 to 50 can include 1 to 10, 1 to 20, 1 to 30, and 1 to 40 in one direction, or 50 to 40, 50 to 30, 50 to 20, and 50 to 10 in the other direction.

In the detailed description herein, references to “embodiment,” “an embodiment,” “one embodiment”, “another embodiment,” “in various embodiments,” “certain embodiments,” etc., indicate that the embodiment(s) described can include a particular feature, structure, or characteristic, but every embodiment might not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described. After reading the description, it will be apparent to one skilled in the relevant art(s) how to implement the disclosure in alternative embodiments.

As used herein, the expression “adverse food reaction” is referring to an abnormal or exaggerated immune response of a companion animal to the ingestion of a food composition, which negative response can cause a reduced appetite that could lead to a refusal of the diet or a food aversion. An adverse food reaction response can be immune-mediated which is referred to as a food allergy. The said negative response can also be a non-immune-mediated response, called a food intolerance. Illustratively, an adverse food reaction encompasses pruritus, often referred as to itching, and can result in additional dermatological signs, such as alopecia, seborrhoea or pyoderma.

As used herein, the term “allergic reaction” or “allergy” is a clinical altered immune response by an individual to a dietary allergen. Symptoms of allergic reactions can affect the cutaneous (e.g., urticaria, angioedema, pruritus), respiratory (e.g., wheezing, coughing, laryngeal edema, rhinorrhea, watery/itching eyes), gastrointestinal (e.g., vomiting, abdominal pain, diarrhea), and/or cardiovascular (if a systemic reaction occurs) systems. Allergic reaction to a food composition can provoke an adverse food reaction by the companion animal feeding this food compositions.

In the context of the present disclosure, the term “food aversion” refers to an eating disorder in a companion animal that leads to detrimental health outcomes, including renal impairment, nutritional deficiencies, non-optimal puppy development or energy deficits. Food aversion manifests as adverse effects in companion animals, often stemming from a negative association between the taste of a particular food composition and symptoms induced by intoxication, spoilage, or toxic substances. Typically, a food aversion is developed by a companion animal following the ingestion of food compositions that elicit feelings of nausea, induce vomiting or induce an adverse food reaction.

As used herein, the terms “animal”, “companion animal”, or “pet” refers to domestic animals including, but not limited to, domestic dogs, domestic cats, horses, cows, ferrets, rabbits, pigs, rats, mice, gerbils, hamsters, goats, and the like. Domestic dogs and cats are particular non-limiting examples of pets. In a more specific embodiment, the term “companion animal” refers to pets, in particular dog and cat, particularly to puppy and kitten, and more particularly to puppy. As used herein, a “puppy” refers to a young dog aged from about 2 to about 15 months old, depending on the breed and expected adult weight. In some preferred embodiments, a puppy can be less than about 6 months old.

As used herein, the terms “food”, “food composition”, “diet” or “foodstuff’ cover all of foodstuff, diet, food or a material that can contain proteins, carbohydrates and/or crude fats, which is used in the body of an organism to sustain growth, repair and vital processes and to furnish energy. Foods can also contain supplementary substances or additives, for example, minerals, vitamins and condiments (See Merriam- Webster’s Collegiate Dictionary, 10th Edition, 1993). Such food compositions can be nutritionally complete. In a particular embodiment, a food composition according to the present disclosure is a nutritionally complete food composition.

As used herein, “threonine” refers to an amino acid. An amino acid threonine can be used in the biosynthesis of proteins (CAS Registry Number® is 80-68-2). Threonine (Thr) is an essential amino acid needs to be present in the diet of companion animals, such as puppies. This essential amino acid is naturally present in protein source and can be added as a protein supplement in the formulation of the food compositions in order to achieve the target recommended level of threonine suitable for an optimal puppy’s growth.

The term “carbohydrate” includes, for example without limitation, cereals, grains, corn, wheat, rice, oats, corn grits, sorghum, grain sorghum (milo), wheat bran, oat bran, amaranth, durum, semolina, or mixtures thereof.

The term “nitrogen-free extract (NFE)” represents the soluble carbohydrates, such as starch and sugar, of an animal food.

As used herein, the term “fat” encompasses any food-acceptable fat(s) and/or oil (s) irrespective of their consistency at room temperature, i.e., irrespective of whether said “fat” is present in essentially fluid form or in essentially solid form. In some embodiments, the term “fat” includes vegetal fat and/or animal fat. Fat can be supplied by any of a variety of sources known by those skilled in the art. SFat content of foods can be determined by any number of methods known by those of skill in the art. A fat source can comprise, or even consist essentially of a mixture of fatty acids.

As used herein, the terms “fat”, “oil”, and “lipid” are synonymous and also encompass mixtures of fats or oils. Animal fats as well as vegetable oils and/or marine oils can be used. Any commercially available source of animal, vegetable, marine fat can be tested. Plant oils are typically canola oil, soybean oil, com oil, olive oil, sunflower oil, linseed oil, peanut oil, palm oil, palm kernel oil, safflower oil, rapeseed oil, cottonseed oil, coconut oil, and the like. Typical animal fats are beef fat (including beef tallow), pork fat (including pork lard), poultry fat (including chicken fat, turkey fat, duck fat, and combinations thereof), and the like. Marine oils are typically tuna oil, sardine oil, salmon oil, menhaden oil, anchovy oil, fish oil, and the like. Also are encompassed herein fats that are derived from animal, plant, marine sources, or that are produced by animals and plants.

As used herein, the term “dry food composition” generally refers to a food composition having a moisture content of less than 12% by weight, relative to the total weight of the food composition, and commonly even less than 7% by weight, relative to the total weight of the food composition. Dry food compositions can be formed by an extrusion process. In some embodiments, a dry food composition can be formed from a core and a coating to form a dry food composition that is coated, also called a coated dry animal food composition. It should be understood that when the term “dry food composition” is used, it can refer to an uncoated dry food composition or a coated dry food composition. A dry food composition can be a kibble. As used herein, the term “kibble” includes a particulate pellet like component of animal feeds, such as dog and cat feeds, typically having a moisture, or water, content of less than 12% by weight, relative to the total weight of the kibble. Kibbles can range in texture from hard to soft. Kibbles can range in internal structure from expanded to dense.

As used herein “hypoallergenic food composition” as used herein refers to a composition for which a substantially limited or no allergic reaction is achieved upon consumption of the composition. Hypoallergenic food compositions disclosed herein can be dry or wet food compositions. In particular, hypoallergenic food compositions can be dry food compositions.

In the present disclosure, the expressions “hypoallergenic nutritionally complete dry food composition”, “food composition” and “composition” are alternatively used to designate the hypoallergenic nutritionally complete dry food composition of the present disclosure.

As used herein, the term “nutritionally complete” or “nutritionally balanced” means that the composition of the present disclosure provides the complete and balanced nutritional requirement to a companion animal. Specifically, a nutritionally complete food composition contains all known required nutrients for the intended recipient of the food composition, in all appropriate amounts and proportions based, for example, on recommendations of recognized and competent authorities in the field of animal nutrition. In certain embodiments such companion animals are puppies. Therefore, a nutritionally adequate feed is a feed with which the said companion animal, e.g., the said puppy, can be fed as the sole ration and is capable of sustaining life without additional food (except water). The nutritionally complete food composition can contain a carrier, a diluent, or an excipient. Depending on the intended use, the carrier, diluent, or excipient can be chosen to be suitable for animal use.

As used herein the term “optimal” in the context of growth or development refers to a food composition or formula providing complete and balance nutrition for a companion animal, such as a puppy. “Optimal” refers to an appropriate amount of calories supporting the growth and development of a companion animal throughout its life. This is defined as the amount that supports normal growth and maintains the puppy at a balanced lean body condition. The food composition of the present disclosure presents the right balance of protein, calcium, essential vitamins and minerals delivering the energy and vitality needed for supporting growth and development. Fast and low growth is not optimal growth. The optimal growth of a companion animal can be evaluated with the ratio of the weight and the age of the companion animal. In particular, the optimal growth also depends on the breed of the companion animal. The optimal growth of a companion animal can be evaluated by any suitable method known in the art. For instance, the growth can be objectively observed as regard of the line body of the companion animal or evaluated by management tools. Illustratively, the body condition score (BCS) can be used to evaluate body fat of dogs and cats (Body Condition Scores by Lynn Buzhardt, DVM Care & Wellness, Pet Services; or Baldwin et al. Journal of the American Animal Hospital Association, July/ August 2010, Vol. 46).

As used herein, the terms “palatability” or “palatable” refer to being desirable to the palate or taste. Further, the terms “palatability” or “palatable” as used herein refer to the extent to which an animal food product, in particular a pet food product, appeals to the palate or taste of the animal. This is suitable measured by feeding tests, e.g., difference tests or ranking tests. In certain embodiments, “palatability” can mean a relative preference for one food product over another. For example, when an animal shows a preference for one of two or more food products, the preferred food product is more “palatable”, and has “enhanced palatability” or “increased palatability”.

Within the scope of the present disclosure, a reference optimal growth for a companion animal can be obtained by measuring the Body Score Condition (BCS).

For a dog on a 9-scale, a BCS from about 1 to less than 4, in particular would be indicative of an underweight. A BCS from 4 to 5, in particular 4, 4.5, or 5 would be indicative of an ideal weight for a dog. And a BCS from above 5 to 9, in particular 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, or 9 would be indicative of an overweight for a dog.

A BCS of about 4 to 5 is targeted in a canine companion animal to achieve optimal growth and development and avoid nutritional related diseases in adulthood. In particular, a BCS of 4 to 5 throughout the life of the companion animal is optimal.

For a cat on a 5-scale, a BCS from about 1 to less than 2.5, would be indicative of an underweight. A BCS from 2.5 to 3.5 would be indicative of an ideal weight for a cat. And a BCS from above 3.5 to 5 would be indicative of an overweight for a cat. A BCS of 2.5 to 3.5 is targeted in feline companion animal to achieve optimal growth and development and avoid nutritional related diseases in adulthood.

In complement, a reference optimal growth for a companion animal can be obtained by measuring the muscle condition score (MCS). The MCS differs from the BCS in that the MCS evaluates muscle mass. Evaluation of muscle mass includes visual examination and palpation over the temporal bones, scapulae, lumbar vertebrae and pelvic bones.

The term “ppm” or “parts per million” is herein used according to its conventional meaning. More precisely, it refers herein to a weight amount relative to the total weight of the dry matter of the food composition (e.g., mg/kg) (unless otherwise indicated).

Units

All weight percentages expressed herein are by weight of the total weight of dry matter of the food composition unless expressed otherwise.

As used herein, an amount of a component as expressed as weight/Mcal can consist of a weight amount of the said component by unit of Metabolizable Energy (ME) of the total animal food composition.

As used herein, the ME parameter is intended to represent the energy value of a food composition that is directly metabolized after consumption. Within the scope of the present disclosure, the ME value can be measured by any suitable method known in the art.

Illustratively, the ME value can be measured using feeding trial. In practice, the gross energy (GE) of the food is determined in the laboratory, and the amounts of food eaten by the animals are recorded. The feces and urine from the animals are collected, and the energy in each is determined and called fecal energy (FE) and urinary energy (UE), respectively. The ME is then calculated by the following formula:

ME (kcal/kg) = [GE - (FE + UE)] / Kg of food consumed.

Alternatively, the ME value can be measured by a mathematical method, in particular taking into account the percentage of crude fat (CF), the percentage of crude protein (CP), and the percentage of carbohydrates (NFE) in the composition. In practice each percentage is multiplied by its respective Atwater Factors. The resulting sum is then multiplied by 10. The mathematical method can be represented by the following formula:

ME (kcal/kg) = 10 x [(3.5 x CP) + (8.5 x CF) + (3.5 x NFE)].

Metabolizable Energy is conventionally determinable according to standard methods, and especially according to the modified Atwater factorial equation proposed by the National Research Council (NRC) in 2006 (Calvez et al., PLoS One. 2019). 2. HYPOALLERGENIC NUTRITIONALLY COMPLETE DRY FOOD COMPOSITION

A hypoallergenic nutritionally complete dry food composition of the present disclosure shows advantages in promoting and supporting the growth of a companion animal, in particular a puppy, especially for a companion animal suffering from adverse food reaction.

The present disclosure relates to a hypoallergenic nutritionally complete dry food composition for a companion animal, preferably a puppy, wherein said composition can include: about 20% to about 25% by weight of vegetal proteins, said vegetal proteins having at least about 95% by weight of hydrolyzed vegetal proteins; about 15% to about 25% by weight of fat; about 200 ppm to about 500 ppm of vitamin C; about 400 ppm to about 900 ppm by weight of vitamin E, about 0.5% to about 2% by weight of calcium (Ca); about 0.5% to about 1.5% by weight of phosphorus (P); and about 0.5% to about 1.5% by weight of threonine (Thr), the weight percentage and ppm by being expressed on a dry matter basis.

Indeed, the said hypoallergenic nutritionally complete dry food composition can comprise other substances (such as fiber, lutein, taurine, beta-carotene, natural flavor(s), etc.) so that its composition amounts to 100% by weight on a dry matter basis.

The food composition according to the present disclosure is prepared according to the techniques which are well known to a person skilled in the art.

The palatability of the hypoallergenic palatable compositions according to the present disclosure can be measured by any suitable known method in the art. For example, the palatability of a food composition can be assessed using a single bowl test or a by a two- bowl test or other methods for determining palatability (Aldrich et al. Animals (Basel). 2015 Jan 16;5(l):43-55).

EXAMPLES

For purpose of understanding and not limitation, the presently disclosed subject matter will be better understood by reference to the following Examples, which are provided as exemplary of the disclosed subject matter, and not by way of limitation.

The present examples 1, 2 and 3 provide a hypoallergenic dry food composition according to the present disclosure along with assessments of its palatability and digestive tolerance when administered to puppies. Example 4 presents results on food acceptance, growth evolution and digestive tolerance of a hypoallergenic dry food composition according to the present disclosure. EXAMPLE 1: MATERIAL &METHODS

/. Test for assessing palatability

The palatability of the hypoallergenic dry food composition was determined using a “Two Bowl Test”. This test allows to determine the palatability of a food regarding the food preference of the animal between two different food products.

In this test 30 puppies were enrolled. A hypoallergenic dry food composition and a control food composition were placed in their respective bowls and presented simultaneously to each animal. The bowls are left with the animal for 20 minutes. The amount of food product offered in each bowl is sufficient for the animals’ daily caloric intake. The test is performed twice a day. Fresh water was always available. The remaining food product were collected and weighed to determine how much of each food product was consumed by the animal. Each food product is classified alongside the others as a function of its consumption. The palatability was measured according to the diet preference: the percentage of animals which prefer diet A, versus the percentage of animals which prefer diet B, and the percentage of animals which don’t have any preference (no choice).

2. Test for assessing digestive tolerance

The digestive tolerance of the hypoallergenic dry food composition was determined with the observation of the quality of stool (faecal scoring system).

The study length requires 10 days and pets are fed with the same diet during the 10 days (5 days of acclimatation of the diet and 5 days of fecal collection). No less than 6 animals must complete the study. All animals included in the study are stool graded daily during the fecal collection phase thanks to the fecal score scale hereinafter.

Fecal scoring system for dogs (® Royal Canin, 2017) on a 5-scale :

Score 1 : Hard, dry, crumbly stool (crumbs)

Score 2: Dry, very clearly defined cracks

Score 2.5: Clearly defined shape with visible cracks (optimal)

Score 3: Moist stool starting to lose shape and cracks

Score 3.5: Moist stool with no cracks

Score 4: Moist stool with little consistency and no real shape

Score 4.5: Liquid stool with minimal consistency

Score 5: Entirely liquid stool (no texture).

At the end of the study, the mean weighted score is determined for each animal. Protein indigestibility, measured on Table 5, is the fraction of the protein in a foodstuff that is not assimilated by the animal’s digestive system as a % of the total quantity of protein ingested. The protein indigestibility is estimated in our laboratory using the ileal digestibility measuring method or “BOISEN method”. This method is proved to be the best in vitro method to predict the ileal digestibility in monogastric species and is recognized as the reference for in vitro evaluation of digestibility (Boisen S., and Fernandez JA. 1995. “Prediction of the Apparent Ileal Digestibility of Protein and Amino Acids in Feedstuffs and Feed Mixtures for Pigs by in Vitro Analyses.” Animal Feed Science and Technology 51 (1- 2): 29-43.).

Therefore, the hypoallergenic nutritionally complete dry food composition is palatable and well accepted for puppies of any breed and does not cause food aversion.

EXAMPLE 3: DIGESTIVE TOLERANCE RESULTS

The results on stools, digestibility and body weight variation for all dogs included in the study are presented below.

Table 4. Distribution of stools quarter for the dogs The optimal target fecal score was 2.5 (optimal score in the fecal scoring usual scale). The average fecal score obtained was 2.8. Therefore, the hypoallergenic dry food composition of the present disclosure is well tolerated and digestible by the dogs. There was no report of diarrhea.

Table 5. Mean results on the digestibility of all the enrolled dogs

For reference, a diet having a digestibility of dry matter of 83% or more and a digestibility of proteins of 86% or more is considered to be a highly digestible food composition. A diet having a digestibility of dry matter of 81% or more and a digestibility of proteins of 83% or more is considered to be a standard food composition.

Table 6. Body weight variation, in 10 days collection, during the test

The puppies maintained good body weight (no loss >5% in 10 days collection) which confirms the dogs ate the food composition consistently and achieved their energy requirements.

EXAMPLE 4: RESULTS FOR ACCEPTANCE, GROWTH EVOLUTION, AND DIGESTIVE TOLERANCE

The present example present results on food acceptance, growth evolution and digestive tolerance of a hypoallergenic dry food composition according to the present disclosure.

Table 7. Characteristics

4.2 Food Acceptance Results

To assess the food acceptance of the hypoallergenic dry food composition among the puppies, it was evaluated, based on scores provided by the owners, the following categories:

(a) the easiness to eat of the diet (Score: Ranging from 1 [very difficult] to 9 [very easy]),

(b) Amount of food consumed per meal by the animal (Score: Ranging from 1 [none of the food offered was eaten] to 9 [all of the product offered was eaten]),

(c) Enjoyment of the diet by the animal (Score: Ranging from 1 [puppy did not enjoy at all] to 9 [puppy enjoyed extremely], and

(d) Assessment of the kibble by the pet owner (For the kibble size: Score ranging from 1 [much too big] to 3 [just about right] to 5 [much too small]. For kibble texture: Score ranging from 1 [much too hard] to 3 [just about right] to 5 [much too soft]. For the “chewiness” of the kibble: Score ranging from 1 [not nearly chewy enough] to 3 [just about right] to 5 [much too chewy]).

Results based on the average scores from the pet owners: a. The diet was considered “very easy” to eat for 9 puppies and “easy to eat” for the remaining puppies. b. Eight puppies consumed all the food offered, and the remaining puppies ate more than half of the food offered. Therefore, the food was consumed in appropriate quantities. c. All pet owners reported that their puppies enjoy the food composition, with 9 owners indicating that their puppies enjoyed the food extremely. Furthermore, most of the puppies enjoyed the food composition more than their previous diet. d. More than half of the pet owner found the kibble size to be “just about right” (score 3). All pet owners found that the kibble texture to be “just about right”. Finally, 9 pet owners rated the kibble “chewiness” as “just about right” (score 3).

In conclusion, the hypoallergenic dry food composition of the present invention has kibble features adapted to growing puppies and is palatable.

4.3 Growth evolution results

To assess the growth evolution of puppies fed with the hypoallergenic dry food composition, it was evaluated the Body Weight (BW) evolution and the Body Condition Score (BCS) evolution of the puppies.

Evolution of the average body weight (in kilograms) for the growing puppies fed with the food composition is shown in Table 8 below:

Table 8._Evolution of the average body weight for the growing puppies

The results show that the evolution of Body Weight follows the classical trend observed in growing puppies for that age and size, with a slight progressive increase over time.

The body condition score evolution results are shown in Table 9 below:

Table 9 Body Condition Score evolution The results show that the BCS remains within correct limits (around 4-5). When interpreted in parallel with the body weight (BW) evolution, this suggests that the progressive increase in weight is not associated with an increase in fat mass but rather with an increase in lean body mass, which is favorable for the puppy.

4.4 Digestive Tolerance Results

To evaluate the digestive tolerance of the hypoallergenic dry food composition in puppies, it has been assessed the consistency of the feces and the fecal frequency of the puppies. a. The results indicate that the stools exhibited good consistency, with fecal scores consistently falling between 2 and 4. There were no scores of 1 or 4.5-5. The average fecal score (FS [D10-D30]) was 2.65, which falls within the range considered as ‘optimal’ for puppies. b. It has been observed a notable enhancement in the frequency of defecation during the study, with no puppies exhibiting bowel movements 4-5 times per day by the end of the study. The overall results regarding digestive tolerance are highly favorable.

CONCLUSION

As supported by the examples above, the present disclosure successfully provides a well -tolerated, highly digestible and palatable new hypoallergenic nutritionally complete dry food composition, including ingredients which provide hydrolyzed vegetal protein and an optimal nutritional level of proteins, vitamins, calcium, phosphorus, threonine and/or fat.

In particular, this hypoallergenic nutritionally complete dry food composition is preferably formulated for a young companion animal, preferably a young dog (puppy), especially those susceptible or predisposed to adverse food reaction or those suffering from adverse food reaction.

The hypoallergenic nutritionally complete dry food composition as described herein does not provoke allergic reaction in companion animals. In particular, the hypoallergenic nutritionally complete dry food composition of the present disclosure is formulated to avoid or at least minimized the risk of a food aversion.
