Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of using gypsum or an aqueous gypsum solution for feed.

[0002]

2. Description of the Related Art Generally, in order for animals to grow up healthy and to obtain good quality meat, milk and eggs, it is necessary to ingest a sufficient amount of calcium. For this reason, livestock etc. may be fed with a feed containing a large amount of calcium, or may be fed with a mixture of shells and a calcium drug in the feed. The amount of calcium that elutes is a very small amount, and most of the calcium is discharged outside the body as it is and is not being efficiently ingested by livestock.

Further, a feed composed of grains, fish meal, etc. is oxidized with the passage of time to accumulate oxides, or putrefaction proceeds. When such a feed is given to livestock, symptoms such as diarrhea may appear and the physical strength may be weakened.

Furthermore, in recent years, attention has been paid to the influence of methane gas emitted from livestock on the environment. In other words, the greenhouse effect of carbon dioxide, which has been pointed out as the cause of global warming and has begun to be discussed among countries regarding emission control, far surpasses the greenhouse effect of carbon dioxide. According to the US Department of Energy's estimation, the amount of methane gas that produces an effect is estimated to be 400 million tons or more per year. Of this, about 20% is emitted from paddy fields, but methane gas emitted from herbivores is about 15%. And it is the second most common source. Generally, ruminants such as cows and goats discharge methane gas generated in the process of decomposing and fermenting plant fibers into the atmosphere by the action of microorganisms that live in the digestive system. For example, the amount of methane gas emitted per day of cows is about 360 g, and the number of domestic cattle raised is about 4 million. With simple calculation, about 520,000 tons of methane gas per year is released into the atmosphere. In addition to this, it is pointed out that the impact of livestock on global warming is greater than expected considering that 30,000 goats and about 30,000 sheep are bred. ing.

The methane gas produced by such livestock is not always accompanied by normal digestive activity, but contains a considerable amount of methane gas produced by abnormal fermentation occurring in the digestive system due to lack of freshness of feed. Therefore, the budget for researching feed and feeding methods etc. to suppress the production of methane gas is 1
Trials such as the addition to the Ministry of Agriculture, Forestry and Fisheries have begun since fiscal 991, but such research is still in its infancy and effective results are left as future tasks.

[0006] In the recent gourmet boom, for example, aquaculture of shrimp and high-grade fish has become popular in various places, and various kinds of fish are often cooked alive. "Ikesu" live fish from the production area
Although live fish are sometimes transported directly as they are, and live fish are kept alive for a certain period of time in a restaurant, however, the water quality may be deteriorated and the survival rate may be reduced due to the excrement (for example, ammonia) of the fish itself. Improving the survival rate of fish in such cages and aquariums is directly linked to the success or failure of the project, and if not kept in a healthy state for a certain period of time, the taste will be affected. For that reason, vitamins, oxygen, etc. are given along with the food, but the effect is not fully exerted.

Therefore, in view of the above conventional circumstances, the present invention has
It is an object of the present invention to breed livestock and fish, improve the taste of meat, milk and eggs obtained from the livestock and to provide a feed that is effective for fish farming, transportation and breeding.

[0008]

In order to achieve the above object, the present invention employs the following means. That is, a gypsum aqueous solution in which a trace amount of gypsum is dissolved in water, or after heating the water to dissolve the gypsum, the gypsum aqueous solution returned to room temperature is fed to an animal such as livestock. It is also possible to feed gypsum directly to feed and give it to animals such as livestock.

Furthermore, there is a method of using gypsum or a gypsum aqueous solution in which water in a water tank or a water tank is partially replaced with the above-mentioned gypsum aqueous solution or a small amount of gypsum is dissolved.

[0010]

[Effect] By dissolving gypsum in drinking water of livestock or by giving an aqueous solution of gypsum, calcium content can be efficiently absorbed in the body and the vitality of livestock is improved. Furthermore, by adding gypsum to the feed, the feed is kept from being oxidized and spoiled to keep it fresh for a long time, and the gypsum is directly absorbed by the livestock to improve the vitality of the livestock.

Furthermore, the calcium contained in the gypsum mixed in the feed by the above method is efficiently ingested by the livestock to neutralize the oxides present in the digestive organs of the livestock, and at the same time, to be oxidized and exhausted. By returning the feed to a fresh state, it has an action of preventing abnormal fermentation in the digestive organs and suppressing the amount of methane gas produced. Immediately after the livestock defecation, mixing the amount of gypsum with the feces immediately after defecation, the odor disappears immediately, or when a person ingests a very small amount of gypsum with food, there is no odor in that person's defecation. , Or armpit odor, athlete's foot, which is excrement from the skin,
The action of the above-mentioned gypsum can be inferred in consideration of the fact that wiping and the like disappear at all.

Further, by substituting a part of the water in the water tank or the water tank with a gypsum aqueous solution or dissolving a trace amount of gypsum, the oxides eluted in the water by the excrement of fish raised or cultivated or the spoilage of the bait. To neutralize and maintain proper water quality.
Further, by giving gypsum together with the feed, it is possible to efficiently ingest calcium in fish or the like and give vitality.

EXAMPLES The present invention will be described in detail below based on examples. = Honkamo = The administration test of the present invention was carried out at a breeding farm in Manano Town, Otado County, Kagawa Prefecture, where 200 duck and 400 duck are bred in one duck house.

The administration method was performed by mixing gypsum powder in feed and drinking water. After administration, the coat and beak are glossy, especially the pink part of the nostrils becomes clear,
It became a beautiful figure. The obtained duck organs, especially the liver, swelled well, and the weight of each individual also increased. = Fish farming = A test was conducted at the Hiwasa Fisheries Research Institute, Tokushima Prefecture, in which 1 part by weight of gypsum powder was administered to 1000 parts by weight of seawater.

Water quality / transparency While the transparency was 88.2 before the addition, it was 5 after the addition.
The day-to-day transparency was 86.7 to 86.9, and there was no large change in transparency before and after the addition, and there was no large change in the transparency for 5 days after the addition.

Five days after the introduction of the microorganism, no death of the microorganism in seawater was observed. Degradation of salinity No change before and after injection.

The dissolution rate in seawater is within 68%. Oxygen concentration 5000 / l The injection rate is slightly worse than that without injection.

No toxic substances or harmful substances are found. Further, as a result of the above, it was judged that it is appropriate to administer about 500 g of gypsum powder to 1 t of seawater, and thereafter it is desirable to administer additional doses little by little over time.

Based on the results of the seawater test, 1 part by weight of gypsum powder was dissolved in 1000 parts by weight of water in a water tank used for transporting or culturing live fish. The calcium content neutralized acidic substances such as fish excrement (ammonia) accumulated in the water in the aquarium, and the survival rate was improved.

Two water tanks containing goldfish were prepared, one of which was prepared by replacing 1/10 of the water in the water tank with a gypsum aqueous solution having a concentration of 3%, and the other of which was ordinary tap water. , An air generator was attached, "bait" was not given, and a test was conducted on the assumption that it would die at some point.
All 10 goldfish died in the day, but only 2 of the goldfish using gypsum or gypsum solution died. = Chickens = In a poultry farm, a mixed feed containing 1% by weight of gypsum was applied to egg-laying chickens, and the collected egg weight, egg diameter, egg shell strength, egg shell thickness, egg yellow, H. U (how unit) was measured, and the results are shown in Tables 2 (a) to (e). The measurement conditions are as shown below. Test target chicken

[0021]

[Table 1]

Test Procedure Administration was started on May 18, 1990, and each value was measured every month. Criteria for evaluation It is judged to be effective if the results in June and July, when egg quality declines the most in a year, do not fall below the results in May, which is the start of administration. Test results As shown in Table 2, the results at the time of the 4th measurement (July 4th) were comparable to those of the 1st time, and the weather was particularly good even after the end of June, when hot days continued. Maintaining the same level of egg quality is considered to be effective by the administration of the gypsum according to the present invention.

Also, in chickens in which the same amount of oyster shells or calcium carbide was mixed in the feed as the above-mentioned gypsum and administered, 6, 7
A remarkable effect was confirmed in comparison with the sharp drop in the egg quality of the moon. U (how unit) [the index for judging the slackened state of egg white and the higher the value, the more fresh the index] is maintained at a high value, indicating that the calcium of the present invention was efficiently absorbed by chickens. Shows.

[Table 2]

= Excretion = Further, when a feed containing the above-mentioned gypsum of several% or less is fed to livestock, the feed is efficiently fed to neutralize oxides existing in the digestive organs of the livestock. At the same time, the oxidized and exhausted feed is returned to a fresh state. As a result, the abnormal fermentation in the digestive organs was prevented and the production amount of methane gas was suppressed. As a phenomenon similar to this phenomenon, the odor immediately disappears when gypsum is mixed in an amount of several% or less (the amount added may be any amount, but several% or less is sufficient) relative to livestock dung immediately after defecation of livestock. Or, when a person ingests a very small amount of gypsum together with food, the person's stool has no odor, or excretion from the skin, such as axillary odor, athlete's foot, and wipes, disappears at all. That is, gypsum acts effectively not only on the excrement excreted from the anus of an animal, but also on the excrement excreted from the skin or the mouth.

[0026]

INDUSTRIAL APPLICABILITY As described above, feeding the gypsum or the gypsum aqueous solution according to the present invention as drinking water or with a feed to livestock improves the fattening state, and the taste of meat, milk and eggs obtained from the livestock is improved. It becomes more compact and its yield is higher than that of livestock fed only conventional feed.

Furthermore, by administering gypsum to the exhausted and oxidized feed according to the present invention, the oxides in the livestock are neutralized, and the abnormal fermentation in the digestive organs is effectively suppressed to occur in the livestock. It has the effect of suppressing the amount of methane gas generated.

Further, by substituting a part of the gypsum aqueous solution for the aquarium of fishes, water of the fish, or seawater, or dissolving a trace amount of gypsum, it was possible to survive a fish with a good "liveness" for a long period of time. In addition, the taste of fish obtained by dissolving such gypsum or gypsum aqueous solution or gypsum as a raw material thereof or feeding it together with food can be made “more delicious” than conventional meat, milk, and eggs.
