Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feed composition for land or aquatic animals, and more particularly to a feed composition for suppressing the generation of malodor derived from feed ingredients or excrement of domestic animals.

[0002]

2. Description of the Related Art In recent years, great attention has been paid to environmental problems such as water pollution, air pollution, and destruction of nature.
In the fields of livestock and fisheries, air pollution and water pollution due to manure or animal odor derived from farm animals have become a serious problem. In order to solve this problem, for example, equipment investment is required for deodorization, excrement treatment, or the like, or a large amount of cost is required, such as moving from a suburb of a city to a distant place and moving further away. Further, the above environment is not preferable for the health of people involved in the livestock industry, and improvement is required also from this point.

Generally, the intestines of animals are in an anaerobic environment,
Organic nitrogen and organic sulfur are decomposed and excreted by low-molecular-weight ammonia and thiol compounds, respectively, by a group of microorganisms living in the intestine. Also, various nitrogen compounds are decomposed into uric acid, allantoin, urea and other compounds in the cells of animals and excreted in urine. The excrement discharged outside the body is further anaerobically decomposed by anaerobic microorganisms,
It becomes hydrogen sulfide, ammonia gas, thiol derivative, etc., and volatilizes into the atmosphere, causing a bad odor.

As described above, the substances causing the malodor are mainly produced by the enzymes possessed by the anaerobic microorganisms. Since these compounds have a strong putrid odor and cause not only a bad odor but also toxicity to animals including humans, it is necessary to suppress or eliminate the generation thereof as much as possible. Therefore, it is desired to develop an effective method capable of preventing the generation of offensive odors such as ammonia odor and hydrogen sulfide odor generated in farms and the like.

[0005] Conventionally, as a method for reducing the malodor generated in farms for cattle, pigs, chickens, etc., loggerheads and the like have been sprinkled in a barn and mixed with the generated excrement to prevent volatilization of odorous substances. Although it is applied to treatment, the effect of preventing malodor is insufficient.

As another measure, deodorization with various deodorants has been proposed, but these deodorants only mask the bad odor with other odors and are toxic to ammonia gas, hydrogen sulfide and the like. There is no effect of suppressing or removing the generation of substances. Therefore, in the essential sense, a large effect cannot be expected.

[0007] Further, agents such as yucca extract, which is an inhibitor of the enzyme urease that produces ammonia, have been developed, which suppresses the generation of ammonia by acting physiologically, but neither of them has sufficient effect, and There is a problem that it is very expensive.

[0008] Further, when a conventional feed such as fish meal which is easily spoiled is used as a raw material, there is a problem that spoilage occurs during storage to cause a spoiled odor and the feed value is lowered.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems, the object of the present invention is to use an inexpensive material to prevent the generation of malodorous or toxic substances such as ammonia derived from feed ingredients or manure of domestic animals. An object of the present invention is to provide a feed composition that can be significantly suppressed or eliminated.

[0010]

The present invention is a feed composition comprising a feed ingredient and one or more selected from the group consisting of zeolite, silica gel, alumina and activated carbon. .

The feed composition of the present invention is a feed composition for raising livestock animals such as cows, pigs and chickens, as well as terrestrial or aquatic animals such as aquatic animals such as seafood, laboratory animals and pet animals. It is a thing.

The feed ingredients constituting the feed composition of the present invention are not particularly limited as long as they are a nutrient source for the above animals,
Conventionally used feeds or feed compositions can be used. For example, a feed obtained by adding feed additives such as vitamins, minerals, and antibiotics to the main nutrition sources such as grains, hay, fish meal, oil meal, beer meal, and fats and oils can be arbitrarily selected according to the breeding animal. In addition, as such a feed component, a commercially available feed can also be used.
Examples of such commercially available feeds include the following as feeds for dairy cattle, beef cattle, pigs, meat chickens, and layer chickens.

Feed for dairy cows Weight part Corn silage 74 Clover hay 10 Wheat barley 5 Dried beer lees 10 Vitamin and mineral additives 1

Feed for beef cattle Weight part Corn 49 Soybean meal 25 Clover hay 10 Wheat barley 5 Dry beer meal 10 Vitamin / mineral additive 1

Feed for swine Part by weight Corn 30.5 Mylo 30.5 Soybean oil meal 6 Fish meal 4 Bran 10 Defatted rice bran 8 Alfalfa meal 6 Molasses 3 Vitamins, amino acids, minerals 2

Meat chicken feed parts by weight Corn 54.2 Mylo 21.7 Raw soybean 11.9 Fish meal 4.3 Corn gluten meal 4.9 Alfalfa meal 2.2 Calcium phosphate 0.3 Salt 0.2 Vitamins 0.3

Feed for laying hens Weight part Corn 65.6 Fat Nuka 2.7 Soybean meal 10.2 Rapeseed meal 4.2 Corn gluten meal 1.9 60% Fish meal 4.0 50% Meatbone meal 4.5 Feather meal 0.7 Beef tallow 5.0 Vitamins, minerals 1.2

Zeolite, silica gel, alumina and activated carbon used in the present invention are not particularly limited as long as they are generally used. These are porous and have a large specific surface area, and various products are sold due to differences in their pore diameters and particle sizes, but any of them can be used.

For example, zeolite has a length of 1 c
m, diameter 5 mm, pelletized zeolite, particle size 30 to 5
Examples thereof include 0 mm, 1 to 3 mm, 0.5 to 1 mm granular zeolite, and 200 mesh pass powdery zeolite (all manufactured by Sieglite Co., Ltd.). Similar to zeolite, silica gel is commercially available in the form of beads or powder, depending on the particle size, such as Silbead (trade name, manufactured by Mizusawa Chemical Industry Co., Ltd.).

Similar to zeolite, alumina is also marketed in the form of beads or powder in terms of particle size. Mizuka Sieve (manufactured by Mizusawa Chemical Co., Ltd., trade name), activated alumina (Sumitomo Chemical Co., Ltd. ), Product name) etc. Acidic, neutral, and alkaline activated carbons are commercially available due to the difference in surface treatment, but any of them can be used, for example, Shirasagi C and Shirasagi A (both are products of Takeda Pharmaceutical Co., Ltd.). .

The shapes of zeolite, silica gel, alumina and activated carbon are not particularly limited, but pellets and granules are preferable because they are excellent in handleability and workability when used in combination with feed. Zeolite, silica gel, alumina and activated carbon may be used alone or in combination of two or more.

The blending ratio of each component is 0.01 to 100 parts by weight in total of one or more kinds selected from the group consisting of zeolite, silica gel, alumina and activated carbon per 100 parts by weight of the feed.
It is desirable to add 30 parts by weight, preferably 0.5 to 15 parts by weight. If the amount is less than 0.01 parts by weight, the effect is small, and if the amount is more than 30 parts by weight, the effect is not expected to be improved and the nutritional value as feed is lowered, which is not preferable, but in some cases, 30 parts by weight You may mix beyond.

The feed composition of the present invention can be produced by mixing the respective components in a mixing machine such as a mixer so as to have the above-mentioned mixing ratio. Zeolite, silica gel, alumina, or activated carbon may be mixed with a feed ingredient in advance to form a feed composition, or may be mixed with a feed ingredient at the time of feeding to give a feed composition, which can be fed to domestic animals.

The feed composition of the present invention is used not only for livestock animals such as cattle, pigs, sheep, goats, horses, chickens, turkeys, ducks and geese, but also for aquatic animals, laboratory animals and pet animals. be able to. Of these, it is particularly suitable for land animals such as livestock animals, but it can also be used for underwater animals such as marine animals. The feed composition of the present invention can be fed to the above-mentioned domestic animals as it is or after being mixed with other feed ingredients.

By feeding a feed composition containing the zeolite, silica gel, alumina or activated carbon of the present invention to a breeding animal, the malodorous substances or toxic substances in the feces and urine are adsorbed by the zeolite etc. Can be significantly reduced. As a result, generation of offensive odorous substances or toxic substances in the livestock shed and its surroundings can be significantly suppressed, and a more favorable environment can be maintained. Further, since zeolite, silica gel, alumina or activated carbon does not change at all in the animal digestive system and is neither digested nor absorbed, it does not adversely affect the health of animals. In addition, all of the paid food is excreted as feces outside the body,
It also absorbs malodorous or toxic substances generated by decay after discharge, and suppresses generation of odors in the livestock shed and its surroundings even after discharge.

Further, when a perishable raw material such as fish meal is used as the raw material for the feed, the spoiled odor generated by the spoilage during storage is also adsorbed, so that no bad odor or toxic substance is generated during storage. The feed value can be maintained at a high level.

[0027]

As described above, according to the present invention, since the feed ingredient is mixed with zeolite, silica gel, alumina or activated carbon, the feed ingredient or the excrement of a domestic animal is derived from an inexpensive material. A feed composition capable of significantly suppressing or eliminating the generation of malodorous or toxic substances such as ammonia is obtained.
