Description

  The present invention relates to a pet food for small animals such as dogs and cats.

  Due to the pet boom, the number of pets is increasing, and due to the aging of pets, lack of exercise, overnutrition, etc., adult diseases similar to humans such as obesity, diabetes, liver disease etc. are also increasing in pets. . In addition, there are an increasing number of dogs and cats who are in poor health due to hormonal imbalance after contraceptive surgery. The pet in such a state is not well-groomed and the skin condition is unhealthy.

Many pet foods have been developed to improve health for pets in this situation. For example, in order to improve the immune function of the skin, lactic acid bacteria are used in pets as probiotics (Patent Document 1), and compositions containing oligosaccharides as probiotics to improve inflammation (Patent Documents) 2) In order to improve the vitality of pets, techniques such as a method of combining fructooligosaccharides as probiotic microorganisms and prebiotics (Patent Document 3) have been proposed.

  However, although the above-mentioned technique certainly has an effect of promoting the health of pets to some extent, it cannot be said to be sufficient when evaluated from the viewpoint of whether it looks healthier from the aspect of appearance.

  An object of the present invention is to provide a pet food for not only improving the physical condition of a pet and improving health but also making the appearance of the pet healthier and more beautiful.

Therefore, the present inventors have studied on excellent foods necessary for making the appearance of pets healthy and beautiful in order to obtain a pet food for achieving the above object. It has been found that a certain combination has an effect of improving pet hairiness. As probiotics, lactic acid bacteria that have been proposed in the past are used, and as prebiotics to be combined, it has been found that malto-oligosaccharides that have not attracted attention in the past are effective among oligosaccharides.
That is, this invention provides the pet food containing maltooligosaccharide and lactic acid bacteria.

  The pet food of the present invention is effective not only to improve the physical condition of the pet and promote health by eating, but also to make the appearance of the pet's hair, etc. healthier and more beautiful.

The maltooligosaccharide used in the pet food of the present invention is an oligosaccharide obtained by linearly polymerizing 3 to 10 molecules of glucose and α-1,4 glucoside bonds. Maltose in which two molecules of glucose are polymerized naturally exists as a main component of malt starch syrup, and malto-oligosaccharides in which three or more molecules are polymerized are also included in the starch syrup. Among these malto-oligosaccharides, those having a glucose polymerization degree of 4 to 7, that is, maltotetraose, maltopentaose, and maltohexose are preferable from the viewpoint of improving the appearance of pet hair and the like.

The method for producing maltooligosaccharide is not particularly limited, but for example, a method of partially hydrolyzing starch or the like with acid, α-amylase or the like, a malto-oligosaccharide-producing amylase of microbial origin that specifically produces malto-oligosaccharide having a specific degree of polymerization It can manufacture by the method of utilizing. These maltooligosaccharides may be purified according to their usage, application, dosage form, and other purposes. However, considering the dosage or effects of oral administration, use as high purity maltooligosaccharides as possible. Is preferred. The content of malto-oligosaccharide in the total sugar is 30% by mass (hereinafter simply referred to as “%”) or more, more than 50%, and particularly 80% or more, which improves the appearance of pet hair and the like. To preferred. Moreover, it is preferable from the same point that the content of maltooligosaccharide having a degree of polymerization of sugar of 4 to 7 in the whole sugar is 20%, further 30%, particularly 50%.

The maltooligosaccharide thus obtained is generally a colorless transparent liquid or white powder. Maltooligosaccharides are odorless, excellent in taste, have a mild sweetness, and are excellent in acid resistance and heat resistance. In addition, LD ₅₀ is 20 g / kg or more in rats, which is excellent in safety. Therefore, it can be blended in pet food as it is. The amount to be blended in the pet food varies depending on the age of the pet, but the maltooligosaccharide is preferably 1 kg body weight, 10 to 3000 mg per day, more preferably 100 to 1000 mg, which is taken once or several times a day. It is preferable to improve the appearance of pets, such as their hair.

Example 1 and Comparative Examples 1-3
The test meal having the composition shown in Table 1 was fed by free feeding for 28 days to 16 domestic dogs shown in Table 2 (divided into 4 groups, each having 4 test meals). As the lactic acid bacteria, Enterococcus ficarius EC-12 strain (Combi) was used, and as the maltooligosaccharide, Fujioligo 450P (Nippon Food Processing Co., Ltd., maltooligosaccharide 70% having a glucose polymerization degree of 4 to 7) was used. Each pet after 28 days was evaluated for “hairiness” and “overall evaluation” according to the following criteria, and an average value was obtained for each group. The results are shown in Table 1 and FIG.

[Evaluation criteria for hair growth]
As a question item, “How did you change“ Muzuya ”compared to before changing to this test meal? ”Was selected from the following criteria.
5: Improved 4: Improved slightly 3: Unchanged 2: Slightly degraded 1: Deteriorated

[Evaluation criteria for overall evaluation]
Regarding the question “Do you look healthier than before changing to this test meal?”, One of the following criteria was selected.
5: Looks healthy 4: Looks somewhat healthy 3: Unchanged 2: Looks somewhat unhealthy 1: Looks unhealthy

  As shown in Table 1 and FIG. 1, compared to a test meal that does not contain either lactic acid bacteria or maltooligosaccharide (Comparative Example 1), a test meal that contains only lactic acid bacteria (Comparative Example 2), a test meal that contains only maltooligosaccharide (Comparative Example 3) The pets that gave the test gave somewhat good results for both “hairiness” and “overall evaluation”, but the pet that gave the test containing both substances of lactic acid bacteria and maltooligosaccharides (Example 1), “hairiness” It was found that both the “overall evaluation” improved significantly.

It is a figure which shows the result of the hair after the test meal feeding shown in Table 1, and whole evaluation.
