Description

Detailed Description of the Invention

[0001]

[Industrial application]

The present invention relates to animal feed containing calcium and crude fiber, and more specifically, small pet animals such as dogs, cats and guinea pigs, livestock such as dairy cows and cattle, pigs, horses and chickens, large poultry for competition and large animals for competition. The present invention relates to animal feed containing calcium and crude fiber.

[0003]

[Prior Art]

[0004] In recent years, with the miniaturization of the family structure and the like, the number of households that care for small animals as pets is increasing, and the feed given to these small animals is large, including dried foods and soft semi-raw foods. Marketed, and due to their high nutritional diet, the lifespan of pets can be relatively long.

As a result, while the conventional causes of death of pets were many due to parasites and various illnesses, recent causes of death are the inability to eat food due to weakened teeth or falling out, osteoporosis, and excessive disease. Diseases due to obesity are believed to be increasing.

On the other hand, domestic animals such as pigs, beef cattle, dairy cows, horses and chickens, poultry and competitive horses have been promoted in terms of economic efficiency and the like, and as a result, the breeding environment and the diet for breeding have become highly nutritious. The number of vulnerable animals is increasing, and it is considered that the number of sudden fractures, which were few in the past, and the fragile eggshell in the case of chicken eggs are increasing.

Under these circumstances, the drawbacks of the conventional feeds containing a large amount of phosphate have been pointed out, and the importance of crude fiber and calcium in the feed has been recognized again. The effort is being made.

[0008]

[Problems to be Solved by the Invention]

However, many problems remain in the conventional animal feed containing calcium and crude fiber.

The problem is that, for example, the conventional animal feed containing calcium and crude fiber has a relatively low digestion and absorption rate, and when the crude fiber is ingested at the same time, various advantages of the crude fiber in the feed are obtained. Recently, nutritional studies have shown that absorption of minerals including calcium is inhibited and the excretion of minerals is promoted, although it is exhibited.

On the other hand, although there are some cases where sugar, glucose, etc. were adopted, there has been no report so far that maltitol was adopted as animal feed, and it is used as a sweetener for human taste. Not too much.

Under the above circumstances, coexisting minerals, which is the negative side of crude fiber in feed,
In particular, there has been a strong demand for animal feeds containing calcium and crude fibers, which have improved calcium absorption inhibition and low calcium absorption efficiency.

[0013]

[Means for Solving the Problems]

As a result of intensive studies for solving the above-mentioned problems, the present inventors have found that normal saccharides are digested and absorbed in the upper part of the small intestine, whereas the absorption rate of calcium from the intestinal tract is improved. Came to consider that some influence on the lower intestinal tract is necessary.

Based on this consideration, it was confirmed by an animal experiment that the absorption rate of calcium is improved by blending a predetermined amount of maltitol with calcium.
Surprisingly, it was found that by mixing a predetermined amount of maltitol with crude fiber and calcium to prepare a feed, it is possible to prevent inhibition of calcium absorption by crude fiber, and to use a calcium-maltitol adduct. It was found that similar effects can be obtained by the above, and succeeded in obtaining a calcium- and crude fiber-containing animal feed in which the absorbability of calcium into the animal body was remarkably improved as compared with conventional feeds and crude fiber was ingested. The present invention has been completed.

That is, the present invention is, firstly, a calcium- and crude fiber-containing animal feed containing 1 part by weight of crude fiber, 0.01-1 part by weight of calcium and 0.2-20 parts by weight of maltitol. is there.

Secondly, the present invention is a calcium and crude fiber-containing animal feed containing 1 part by weight of crude fiber and 0.1 to 10 parts by weight of calcium-maltitol adduct.

In carrying out the present invention, there are no particular restrictions on the type and form of the calcium and crude fiber-containing animal feed obtained, and the crude fiber, calcium and maltitol are contained therein in a predetermined ratio. If so, the effect intended by the invention can be obtained, but it is also possible to improve the conventional feed so as to obtain the effect of the present invention by supplementing each deficient component to the processed feed of the conventional formulation. Is.

The crude fiber which can be used in the present invention is natural or artificial, and can be used for feed,
It can be adopted if it has quality and form, for example, even if it is a natural feed such as grains, vegetables, grass and wood and it is not pure crude fiber, it may contain crude fiber in it. Good.

Specific examples include wheat bran for feed, powdered cellulose, beer meal, apple meal, okara, coconut sesame oil residue, various seaweed and its polysaccharides, corn fiber, various gums, konjac mannan. , Various pectins, hemicellulose, lignin, polydextrose, grains such as beans, vegetables, grass for feed, and crushed wood.

Calcium which can be used in the present invention is not particularly limited as long as it has the type, form and quality used for feed in the industry or calcium contained in natural feed.

In carrying out the present invention, as maltitol, those containing maltitol as a main component and of the quality and form generally manufactured and sold as foods can be used. , Amarti Syrup [registered trademark; manufactured by Towa Kasei Kogyo Co., Ltd.], Amarti [registered trademark; manufactured by Towa Kasei Kogyo Co., Ltd.] and the like.

Calcium which can be used in the present invention
Maltitol adducts are referred to as Carbohydrate Research, 24 (1972) 180-183 and 24 (1).
972) 175, the method described in Japanese Patent Publication No. 1-2477.
A method according to Japanese Patent Publication No. 2), for example, a method of dissolving equimolar calcium and maltitol in a heated 80% ethanol aqueous solution or 50% acetone-aqueous solution, allowing to stand and cooling, and then filtering and drying the precipitate. It is a substance in which about 1 molecule of maltitol is added to 1 molecule of calcium hydroxide, and its aqueous solution has a pH of 1
Shows about 1.2. In addition, as its form, powder form,
There are liquid forms, both of which can be used in the present invention.

In carrying out the present invention, the blending ratio of the crude fiber needs to be a level that compensates for the insufficient intake amount of the target animal per day, but the blending ratio of other components. It also has a close relationship with the above, and when maltitol and calcium are 0.2 to 20 and 0.01 to 1 part by weight, respectively, 1 part by weight is the original aim of the present invention. Is preferred from the viewpoint of ingestion and expression of its effect, and blending so as not to inhibit calcium absorption.

Further, in the practice of the present invention, the amount of calcium to be blended must be such that the insufficient intake per day, which is the required amount for the target animal, can be supplemented. There is a close relationship with the blending amounts of other components such as algal and maltitol, and the blending ratio of calcium is 0.
It is preferably from 1 to 1 part by weight.

When the amount of calcium added is less than 0.01 part by weight, the calcium enhancing effect of the feed is often not obtained, and when it exceeds 1 part by weight, maltitol is added. It is not preferable because the effect of preventing calcium absorption inhibition may not be obtained in some cases due to the relationship with the blending amount.

Further, in the practice of the present invention, the content of maltitol should be such that the effect of promoting absorption of calcium or the inhibition of calcium absorption due to intake of crude fiber is prevented. And it is preferable that the amount of maltitol is 0.2 to 20 parts by weight.

If the blending ratio of maltitol is less than 0.2 parts by weight, the effect of preventing calcium absorption inhibition, which is the aim of the present invention, may be insufficient, which is not preferable.
When the amount is more than 20 parts by weight, the effect of the present invention does not increase even if the amount of maltitol added is increased. Therefore, the meaning of the addition is that sweetening for improving the taste of animals. It will be required for other purposes.

In carrying out the present invention, the mixing ratio of the calcium-maltitol adduct is 1 for the crude fiber for the same reason as the determination of the mixing ratio of calcium and maltitol.
When blended in parts by weight, it is preferably 0.1 to 10 parts by weight.

If the blending ratio of the calcium-maltitol adduct is less than 0.1 part by weight, the effect of suppressing the calcium absorption inhibition of the crude fiber may not be exhibited in some cases, and therefore it is not preferable and the blending amount exceeds 10 parts by weight. If
It is not preferable because the resulting feed may have an astringent taste derived from calcium, which may lead to the avoidance of ingestion in some animals.

In addition, it was a feed for animals containing calcium and crude fiber with good calcium absorption efficiency.

[0045]

[Test example]

In order to confirm the effect of the animal feed containing calcium and crude fiber obtained by carrying out the present invention, a comparative test of calcium absorption was carried out as follows. Six-week-old Wistar male rats were given to each group of 6 rats, and the feed prepared in Example 1 was given to the rats. Similarly, except that maltitol was excluded from the composition of Table 1 of Example 1 and corn starch was 660 parts by weight in the same manner, with 6 rats in each group,
A feed compounded in the same manner was given and used as a control. Then, with regard to the present invention group and the control group, after each of them was allowed to freely ingest a diet and bred for 2 weeks, the rats were bred in a metabolic cage for 5 days, urine and feces were collected, and the balance of calcium for these 5 days was calculated. It was measured. Table 5 shows the calcium balance of the rats after feeding for 2 weeks on a regular diet, and Table 6 shows the calcium absorption rate and retention rate derived from Table 5 as the measured calcium balance results. Table 5
It can be concluded that the numerical value inside is the mean value ± standard error of 6 animals in one group, and the numerical value of urinary calcium excretion in the control group and the present invention group is significantly different at a risk rate of 5% or less.

[0047]

[Table 5]

[0048]

[Table 6]

Considering the above test results, it has been clarified that the feed of the compounding ratio obtained by carrying out the present invention realizes a high calcium absorption rate while ingesting crude fiber. Although the reason why these results are obtained has not been clarified, it is considered that the absorption mechanism of calcium is due to active transport in the duodenum and upper jejunum, and diffusion in the lower jejunum and ileum. It is also possible that the difference in Toll's affinity had some effect.
