Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an antibacterial and antiseptic feed additive to be added to general feed given to poultry, livestock, or cultured fish.

Conventionally, in order to prevent the above-mentioned general feeds from deteriorating and becoming toxic, organic fungicides such as nitrofuran-based or pyrimidine-based fungicides have been widely added to these feeds.

However, recently, cancer-causing substances have been found to accumulate in the eggs and meat of animals grown on such additive feed.
It has been confirmed that these organic fungicides can cause cancer in humans who regularly eat them, and the Ministry of Agriculture, Forestry and Fisheries and the Ministry of Health and Welfare have issued orders to completely ban the addition of these organic fungicides to feed. .

However, if some kind of antibacterial preservative is not added to the feed, the feed may rot and deteriorate.

Alternatively, large amounts of malignant pathogenic bacteria such as Escherichia coli and Proteus bacteria may occur in the feed or in the intestines of the animals that eat it, making it impossible to raise these animals satisfactorily.

Therefore, there has been a growing demand among the feed industry and the authorities regulating these for the emergence of totally non-hazardous antibacterial additives to replace these organic chemicals.

The present inventor previously issued Patent No. 646,655 (Japanese Patent Publication No.
No. 34,724) and Patent No. 819,888 (Japanese Patent Publication No. 32,979/1989), a mixture of an appropriate amount of iron sulfate and fly ash or dried natural zeolite fine powder is added to freshly excreted raw chicken manure. The product is then granulated and dried, and the resulting product is used directly as feed, or preferably about 20% by weight is blended into general feed.
It was disclosed that chicken manure itself is odorless, pollution-free, and highly nutritious feed, and that the farmed animals can grow in a favorable, odorless and harmless environment, resulting in improved egg and meat yields.

However, the invention described above is based on the dislike of using human excrement as feed (for example, carp likes to eat human excrement, but it is prohibited to feed carp with human excrement, and people who dare to do this) There aren't any.

), it has not yet been widely implemented.

Recently, when the Ministry of Health and Welfare issued an order prohibiting the addition of organic chemical agents to feed, the present inventor took advantage of the idea of the above patented invention and did not indirectly use chicken manure as an intermediate raw material.
We came up with the idea of adding a mixture of iron sulfate and fly ash or natural zeolite directly to general compound feed, and after conducting various tests, we were able to obtain better results than expected.

First, the production of the feed additive according to the present invention will be explained.

The main raw material, blue-green ferrous sulfate crystals containing 7 molecules of water of crystallization, is an industrial waste that is produced in large quantities as a by-product during the production of titanium white, etc., and is difficult to dispose of.

Since these precipitated crystals have deliquescent properties, it would be extremely difficult to use them as feed additives as they are.

Therefore, for 80 parts by weight of this iron sulfate heptahydrate crystal group,
Fly ash as desiccant or 10 to 2 pieces of finely ground natural zeolite ore dried at approximately 120°C
Mix 0 parts by weight.

The temperature of this mixture is 65°C to 85°C while stirring.
When dried for about 30 minutes, the large heptahydrate crystals naturally disintegrate into fine particles, lose some of the crystallization water, and become white monohydrate crystal particles and light green tetrahydrate crystals. The existence of crystalline particles (dihydrate, trihydrate, and hexahydrate) is unknown.

), and the surface of each particle is coated with fly ash or natural zeolite fine powder.

These fine powders attached to the surface of the crystal particles prevent some of the hygroscopicity of the crystals, and also improve the fluidity of the additive of the present invention, making it easier to add it to feed.

Furthermore, it also has the effect of keeping somewhat moist feed dry.

Fly ash is a finely powdered industrial waste substance collected from the flue gas of coal boilers, and although there are large amounts of natural zeolite ore stored in various places, only a small portion of it is used as cultivation material. Except for
It is an untapped resource that is largely ignored.

The raw materials for the additive of the present invention are all made by effectively utilizing such industrial waste or unused resources, and are unique in that they can provide antibacterial and preservative additives to the feed industry at a very low cost.

It is not only clear from the inventor's existing patents that fly ash and natural zeolite fine powders are harmless from a sanitary standpoint even if they are added to feed and ingested by animals. Various inorganic components are extremely useful as so-called minerals for the growth of animals or when their odor is used as fertilizer for plant growth.

Feed containing this additive maintains a dry state as described above, and is smooth and easy to handle.

Animals that eat this additive feed do not dislike the mixed inorganic additive particles, but rather instinctively and happily ingest them.

Harmful bacteria such as Salmonella (a type of Escherichia coli) are not present in the mixed feed, and feed spoilage is completely prevented over a long period of time.

Furthermore, animals that eat feed containing this additive no longer suffer from diarrhea or dysentery, and because of the iron content in the additive, they do not suffer from anemia or stress, and grow in excellent health. The mortality rate due to the disease has also been drastically reduced to almost zero.

The odor of animals that eat feed containing this additive loses its fluidity and becomes semi-solid, making it easier to clean the odor.

Moreover, the odor evacuation is virtually odorless, and since no ammonia is emitted, there is no respiratory harm to the animals in the nursery.

In this way, the breeding environment improves, so there is no odor pollution around the farm, and the animals are healthy, which improves the egg collection rate, milk collection rate, and meat collection rate, and the livestock efficiency is significantly improved. Improve your skills.

It is stated in the Japanese Pharmacopoeia and the Ordinance for Enforcement of the Ministerial Ordinance on Ingredient Standards for Feed and Feed Additives that it is harmless to hygiene even if animals eat iron sulfate, and that humans do not cause cancer if they eat the meat of these animals. This is clear from the fact that iron sulfate is mentioned as an anti-anemia agent or nutritional supplement.

Moreover, since the aforementioned by-product iron sulfate heptahydrate crystals are recrystallized from an aqueous solution, they do not contain any other impurities.

However, the amount of iron sulfate added to feed as a nutritional supplement is extremely small, and the appropriate amount of iron sulfate to be added to feed as an anemia preventive agent or nutritional supplement is approximately 0.1% by weight of the feed. It is said that there is.

However, it should be noted that this does not act as a bactericidal preservative for feed.

The present invention is the first to use iron sulfate as an antibacterial and antiseptic additive for feed, and it has been found that the appropriate amount of iron sulfate to be added is 0.5 to 1.0% by weight based on the feed.

Implementation fee 1 At a poultry farm with 30,000 chickens that had been complained of odor pollution by the neighborhood, commercially available compounded feed (a mixture of corn, corn, fish meal, soybean meal, and skim milk powder) was given zero
．． 7% by weight of the additive according to the invention (crystalline ferrous sulfate 7
Mix 15 parts by weight of fly ash with 80 parts by weight of water salt,
When a mixture of 1.0% and 1.0% of this product was used, a blend of 1. There is no longer any bad odor in the chicken house, and there is no longer any ammonia odor in the chicken house.

In this comfortable environment, they continue to live in good health without harming their respiratory system, and the egg production rate is about 5% higher than before using the above additive.
% increase.

In addition, conventionally, the odor was in a fluid form, but after using this additive feed, it no longer has fluidity, making cleaning and handling of the odor much easier.

In addition, when this waste odor is collected and dried to produce fertilizer, significant savings in fuel costs have been seen compared to before the use of additive cutting.

If the commercially available compound feed is not mixed with antibacterial and preservative additives, the compound feed will rot and become useless in one month in the summer, but if the additive of the present invention is mixed in, the feed will become useless in the summer. No rotten phenomenon occurred for more than 4 months.

Example 2 In a farm with 4,000 broilers, the ammonia content in the air inside the chicken was about 20%, but the additive of the present invention (in the additive described in Example 1) Temperature 120℃ instead of 15 parts by weight of fly ash
After using a commercially available mixed feed supplemented with 0.5% by weight of 20 parts by weight of finely ground natural zeolite dried in .

Furthermore, the average body weight of broilers increased by about 1601 points for -wings, and the survival rate increased by 3.7% on average, compared to the feed without the above-mentioned additives.

Note that, as in Example 1, the above additive did not cause spoilage in the compounded feed for more than 4 months even in the summer.

Example 3 At a pig farm where 400 pigs are raised, many new public housing units were built around the farm in the two or three years since pig farming started, but the people who lived there were causing foul odor pollution. Appeals were made to the prefecture and city, requesting that the pig farm be relocated, and the issue was even picked up on television, leaving the farm owner in great distress.

Therefore, when the pigs continued to be reared using a commercially available mixed feed containing 0.7% by weight of the additive of the present invention (described in Example 1), the pigs began to enjoy this mixed feed. .

At the same time, there was no longer any bad odor coming from this pig farm, and the problem was completely resolved.

The ingested additive remained in the feces and no longer produced an odor.

When the number of Escherichia coli in the emitted odor was examined, the number was reduced to less than one third compared to when no additive was added.

In addition, previously the odor was soft and yellowish, but after using the additive, the odor became blackish and semi-solid.

Separately, when the additive of the present invention was sprinkled on the floors of livestock farms and piglet barns, it was also possible to prevent the release of odors caused by urination.

In addition, in the past, there were many insect pests such as flies, mosquitoes, and garlic flying around in the livestock barns, but since they started eating the compounded feed containing the additives of this invention, all of these pests have disappeared. I don't seem to have a fever anymore.

Furthermore, excellent effects were observed in the meat quality of pigs raised on feed mixed with this additive, which had an increased reddish tinge and reduced fat content compared to conventional feed.

The effects described above should be similarly exhibited in the case of cattle farming.

Furthermore, when the odorless waste from livestock that has eaten this additive is mixed into the compost, iron and minerals are added to the compost, increasing its fertilizing effect.

Example 4 Eel farming has been carried out in aquaculture ponds exposed to nature for a long time, but it takes about two years from the time eel fry are released into the aquaculture pond until the grown eel is caught and shipped. They hibernate once in the pond mud during the winter.

Due to the proliferation of E. coli in the feed administered over a long period of time, as well as the decay of leftover feed and odor in the mud that accumulates on the bottom of the pond, the hygiene of the eels is seriously impaired, resulting in a large number of eels dying. The survival rate from dead eel fry to live eel is usually less than 50%.

However, when eels in this aquaculture pond were continuously fed with a commercially available compounded feed for eel aquaculture mixed with the additive of the present invention (used in Example 2), the survival rate of the grown eels was 80%.
Good results were obtained, exceeding %.

This is because the amount of E. coli and other pathogenic bacteria in the body is drastically reduced, and the sludge at the bottom of the pond is purified.

Recently, eel farming has become popular in indoor cultivation tanks using heated wastewater from steel mills and other factories.

In this case, the tank water is refreshed throughout the year and kept at an appropriate temperature, so the eels do not hibernate and the young eels become ceremonial eels in eight months.

Furthermore, the survival rate of eel fry has increased to about 75%.

In this case, approximately 0.7 weight □ of the above-mentioned additive of the present invention is added to the feed.
When the combination was administered, the survival rate further increased to 9
The result was that it exceeded 0%.

What's more, I saw that it also had the side effect of completely eliminating the unpleasant odor from the waste water from the aquaculture tanks.
