従来、猫や犬のような伴侶動物（愛玩動物）の栄養状態を評価する方法は、触診やボディコンディションスコアによるもの（例えば、特許文献１）が中心である。伴侶動物の栄養状態を定量的に評価する方法として、採血した血液の成分によるものが知られている。血液成分に基づく伴侶動物の栄養状態の評価は、ヒトの血液成分に基づくヒトの健康状態の評価方法（例えば、特許文献２）と同等に行うことができる。 Conventionally, the method of evaluating the nutritional status of companion animals (pet animals) such as cats and dogs is mainly based on palpation or body condition score (for example, Patent Document 1). As a method for quantitatively evaluating the nutritional status of companion animals, a method based on the components of collected blood is known. The evaluation of the nutritional status of a companion animal based on the blood component can be performed in the same manner as the method for evaluating the human health condition based on the human blood component (for example, Patent Document 2).

Step A: A step of collecting the urine of the companion animal to be estimated.
The collection of urine in step A is performed for urination within a certain period of time.

所定値Ｘは蛋白質の摂食不足の判定値であり、所定値Ｘに基づいて蛋白質の摂食量が不足していることの推定が簡便且つ的確に行われる。
Step D: A step of presuming that the amount of protein consumed is insufficient when the ratio (creatinine concentration / urea nitrogen concentration) is larger than a preset predetermined value X.

工程Ｅ：前記比率（クレアチニン濃度／尿素窒素濃度）が所定値Ｘより大きい場合において前記所定値に対する前記比率（クレアチニン濃度／尿素窒素濃度）の偏差に基づいて蛋白質の摂食不足量を推定する工程。
この工程により、蛋白質の摂食不足量を定量的に推定することができる。
Step E: When the ratio (creatinine concentration / urea nitrogen concentration) is larger than the predetermined value X, the step of estimating the protein intake deficiency based on the deviation of the ratio (creatinine concentration / urea nitrogen concentration) with respect to the predetermined value. ..

By this step, it is possible to quantitatively estimate the amount of protein intake deficiency according to body weight. When the ideal health weight of a companion animal is known, the amount of protein intake deficiency relative to the ideal body weight should be quantitatively estimated by calculating the healthy protein intake according to the ideal body weight. Can be done.
本実施形態による伴侶動物の栄養状態推定方法は、尿中の比率（クレアチニン濃度／尿素窒素濃度）と比率（蛋白質摂食量／カロリー摂食量）とに相関性があることを見出したことに基づくものであり、尿中の比率（クレアチニン濃度／尿素窒素濃度）によって比率（蛋白質摂食量／カロリー摂食量）を推定することができる。 The method for estimating the nutritional status of a companion animal according to the present embodiment is based on the finding that there is a correlation between the ratio in urine (creatinine concentration / urea nitrogen concentration) and the ratio (protein intake / calorie intake). Therefore, the ratio (protein intake / calorie intake) can be estimated from the ratio in urine (creatinine concentration / urea nitrogen concentration).
これにより、触診やボディコンディションスコアによる伴侶動物の栄養状態の推定に比して伴侶動物の栄養状態を個体ごとに的確に推定することができ、しかも尿の採取だけで、採血を必要とすることなく伴侶動物の栄養状態の推定を簡便に行うことができる。 As a result, the nutritional status of the companion animal can be accurately estimated for each individual compared to the estimation of the nutritional status of the companion animal by palpation or body condition score, and blood sampling is required only by collecting urine. It is possible to easily estimate the nutritional status of companion animals.
クレアルチンや尿素窒素等の尿中成分は、血中成分と異なり、最終代謝産物が含まれることや、非侵襲的に採材が可能であることから、代謝状態の評価には最適であり、本実施形態のように、代謝状態を栄養評価に用いることは、フードに対する身体の適応が評価されるために判定までの時間がフード給与開始から長くて１日というメリットがある。 Unlike blood components, urinary components such as creatin and urea nitrogen contain final metabolites and can be collected non-invasively, so they are ideal for evaluating metabolic status. As in the embodiment, using the metabolic state for nutritional evaluation has an advantage that the time until the determination is long from the start of food feeding to one day because the body's adaptation to food is evaluated.
蛋白質の摂食不足の判定値である所定値Ｘは、比率（クレアチニン濃度／尿素窒素濃度）とカロリー摂食量に対する蛋白質摂食量の比率（蛋白質摂食量／カロリー摂食量）との関係に基づいて設定されればよい。 The predetermined value X, which is a determination value of protein intake deficiency, is set based on the relationship between the ratio (creatinine concentration / urea nitrogen concentration) and the ratio of protein intake to calorie intake (protein intake / calorie intake). It should be done.
比率（クレアチニン濃度／尿素窒素濃度）は比率（蛋白質摂食量／カロリー摂食量）が大きくなっても、上昇しなくなる下限値がある。所定値Ｘは比率（クレアチニン濃度／尿素窒素濃度）の下限値に関係して設定されればよく、蛋白質の無駄な摂食、消費をなくすことができる。 The ratio (creatinine concentration / urea nitrogen concentration) has a lower limit that does not increase even if the ratio (protein intake / calorie intake) increases. The predetermined value X may be set in relation to the lower limit of the ratio (creatinine concentration / urea nitrogen concentration), and wasteful feeding and consumption of protein can be eliminated.
比率（クレアチニン濃度／尿素窒素濃度）とカロリー摂食量に対する蛋白質摂食量の比率（蛋白質摂食量／カロリー摂食量）との関係に基づく所定値Ｘは、下記の実験によって適正値に設定することができる。 A predetermined value X based on the relationship between the ratio (creatinine concentration / urea nitrogen concentration) and the ratio of protein intake to calorie intake (protein intake / calorie intake) can be set to an appropriate value by the following experiment. ..
１６頭の成猫（雄）の各々に、高蛋白質フード（４４％，３８０ｋｃａｌ／１００ｇ）から低蛋白質フード（２２％，３５０ｋｃａｌ／１００ｇ）までの４種類のキャットフード、つまり、（蛋白質摂食量／カロリー摂食量）比率が既知となるキャットフードを給与し、各給与キャットフードの場合について、午後５時から翌朝午前８時３０分までの排尿全量及び午前８時３０分から午後５時までの排尿全量を個別に採取し、各尿中の（クレアチニン濃度／尿素窒素濃度）比率を分析した。 For each of the 16 adult cats (males), there are four types of cat food, from high protein food (44%, 380 kcal / 100 g) to low protein food (22%, 350 kcal / 100 g), that is, (protein food intake / calories). Cat food with a known (feeding amount) ratio is fed, and for each cat food, the total amount of urination from 5 pm to 8:30 am the next morning and the total amount of urine from 8:30 am to 5 pm are individually calculated. The samples were collected and the (creatinine concentration / urea nitrogen concentration) ratio in each urine was analyzed.
図１は尿採取時間が午後５時から翌朝午前８時３０分の場合の比率（クレアチニン濃度／尿素窒素濃度）と比率（蛋白質摂食量／カロリー摂食量）との関係を平均値±標準誤差及び折れ線モデルで示している。この場合の寄与率Ｒ２は０．９３４であった。 Fig. 1 shows the relationship between the ratio (creatinine concentration / urea nitrogen concentration) and the ratio (protein intake / calorie intake) when the urine collection time is from 5 pm to 8:30 am the next morning. It is shown by a fold line model. The contribution ratio R 2 in this case was 0.934.
図２は尿採取時間が午前８時３０分から午後５時までの場合の比率（クレアチニン濃度／尿素窒素濃度）と比率（蛋白質摂食量／カロリー摂食量）との関係を平均値±標準誤差及び折れ線モデルで示している。この場合の寄与率Ｒ２は０．９００であった。 Fig. 2 shows the relationship between the ratio (creatinine concentration / urea nitrogen concentration) and the ratio (protein intake / calorie intake) when the urine collection time is from 8:30 am to 5:00 pm. Shown in the model. Contribution R 2 in this case was 0.900.

何れの場合も、比率（蛋白質摂食量／カロリー摂食量）の上昇に応じて、つまり、キャットフードの高蛋白質化に応じて比率（クレアチニン濃度／尿素窒素濃度）が低下し、比率（蛋白質摂食量／カロリー摂食量）が所定値に達すると、比率（クレアチニン濃度／尿素窒素濃度）が下限値を示す。 In either case, the ratio (creatinine concentration / urea nitrogen concentration) decreases as the ratio (protein intake / calorie intake) increases, that is, as the cat food becomes more protein-rich, and the ratio (protein intake / urea nitrogen concentration) decreases. When the (calorie intake) reaches a predetermined value, the ratio (creatinine concentration / urea nitrogen concentration) shows a lower limit.
このことは、伴侶動物が蛋白質を有効摂食することに限界があることを意味し、比率（クレアチニン濃度／尿素窒素濃度）が下限値を示す比率（蛋白質摂食量／カロリー摂食量）より高い比率（蛋白質摂食量／カロリー摂食量）のキャットフードが給与されても、栄養状態上、意味のない過剰の蛋白質摂食となり、無駄な蛋白質の消費になる。 This means that there is a limit to the effective feeding of protein by companion animals, and the ratio (creatinine concentration / urea nitrogen concentration) is higher than the lower limit ratio (protein feeding / calorie feeding). Even if a cat food of (protein food intake / calorie food intake) is fed, excessive protein food is meaningless in terms of nutritional status, resulting in wasteful protein consumption.
尿採取時間が午後５時から翌朝午前８時３０分までの場合は、（蛋白質摂食量／カロリー摂食量）比率が０．１０３で、比率（クレアチニン濃度／尿素窒素濃度）が「Ａ」をもって下限値を示した。この場合は、所定値Ｘ＝「Ａ」とすればよい。尿採取時間が午前８時３０分から午後５時までの場合は、（蛋白質摂食量／カロリー摂食量）比率が０．１０５６で、比率（クレアチニン濃度／尿素窒素濃度）が「Ｂ」をもって下限値を示した。この場合は、所定値Ｘ＝「Ｂ」とすればよい。 When the urine collection time is from 5 pm to 8:30 am the next morning, the (protein intake / calorie intake) ratio is 0.103, and the ratio (creatinine concentration / urea nitrogen concentration) is the lower limit with "A". The value is shown. In this case, the predetermined value X = "A" may be set. When the urine collection time is from 8:30 am to 5:00 pm, the (protein intake / calorie intake) ratio is 0.1056, and the ratio (creatinine concentration / urea nitrogen concentration) is "B", which is the lower limit. Indicated. In this case, the predetermined value X = "B" may be set.
比率（蛋白質摂食量／カロリー摂食量）と、比率（クレアチニン濃度／尿素窒素濃度）との関係は、上述の如く、尿採取時間に関して大きい相違を生じないが、午後５から翌朝午前８時３０分等、尿採取時間が夜間を含むほうが同関係が安定すると推察される。 The relationship between the ratio (protein intake / calorie intake) and the ratio (creatinine concentration / urea nitrogen concentration) does not make a big difference in urine collection time as described above, but from 5 pm to 8:30 am the next morning. It is inferred that the same relationship is more stable when the urine collection time includes nighttime.
以上、本発明を、その好適な実施形態について説明したが、当業者であれば容易に理解できるように、本発明はこのような実施形態により限定されるものではなく、本発明の趣旨を逸脱しない範囲で適宜変更可能である。伴侶動物は、猫に限られることはなく、犬等であってもよい。また、上記実施形態に示した構成要素は必ずしも全てが必須なものではなく、本発明の趣旨を逸脱しない限りにおいて適宜取捨選択することが可能である。 The present invention has been described above with respect to preferred embodiments thereof, but as can be easily understood by those skilled in the art, the present invention is not limited to such embodiments and deviates from the gist of the present invention. It can be changed as appropriate as long as it does not. The companion animal is not limited to a cat, but may be a dog or the like. In addition, not all of the components shown in the above embodiments are indispensable, and they can be appropriately selected as long as they do not deviate from the gist of the present invention.

A step of calculating the ratio of the creatinine concentration to the analyzed urinary urea nitrogen concentration (creatinine concentration / urea nitrogen concentration), and
When the ratio (creatinine concentration / urea nitrogen concentration) is larger than a preset predetermined value, it has a step of presuming that the amount of protein consumed is insufficient.
The predetermined value is set in relation to the lower limit value in which the ratio (creatinine concentration / urea nitrogen concentration) does not decrease even if the ratio of protein intake to calorie intake (protein intake / calorie intake) increases. Nutritional status estimation method.
前記比率（クレアチニン濃度／尿素窒素濃度）が予め設定された所定値より大きい場合において前記所定値に対する前記比率（クレアチニン濃度／尿素窒素濃度）の偏差及び前記体重から体重に応じた健康的な蛋白質の摂食量に対する蛋白質の摂食不足量を推定する工程とを更に有する請求項１から３の何れか一項に記載の伴侶動物の栄養状態推定方法。 The step of measuring the weight of the companion animal to be estimated and
When the ratio (creatinine concentration / urea nitrogen concentration) is larger than a preset predetermined value, the deviation of the ratio (creatinine concentration / urea nitrogen concentration) with respect to the predetermined value and the healthy protein according to the body weight to the body weight. The method for estimating the nutritional status of a companion animal according to any one of claims 1 to 3, further comprising a step of estimating a protein underfeeding amount relative to a food intake.
