Description

[Detailed Description of the Invention] Solid salt for livestock, which has been commonly used in the past, is placed in a suitable place in the livestock pen or pasture and allowed to be freely licked by the livestock to absorb physiologically necessary salts such as minerals and other substances. It is a solid salt that is ingested together with nutrients.

Therefore, such solid salt for livestock is made by adding minerals or nutrients to common salt and applying a special molding technique.In other words, it does not break or disintegrate when ingested, and remains solid for several months (temperature, humidity, etc.). , maintains solid state without being affected by rainwater, etc.)
Furthermore, to prevent waste from being wasted, the water content, hardness, and disintegrability are appropriately adjusted and the product is compressed and solidified using a hydraulic press.

Incidentally, in recent years, Grass Tetani disease caused by magnesium deficiency has been discovered in livestock such as cattle grazing on pasturelands in Japan, and the Grass Tetani disease is increasing year by year.

Traditionally, this disease has been prevented by mixing magnesium salts, such as magnesium carbonate and magnesium chloride, into feed, but feeding on grazing land is difficult and tends to be difficult to prevent.

Therefore, the present invention discovered that when a prepared product was prepared by adding 7 um of magnesium oxide to solid salt for livestock, and the product was fed to pastureland at °C, it had a very good effect.

This type of solid salt is extremely convenient because it can be left freely on grazing land and can be consumed freely.

On the other hand, the daily intake of magnesium that can almost completely prevent magnesium deficiency is lO~20 per adult cow? It is said that.

Therefore, when combined with solid salt, the daily intake of salt is 50~
Since the temperature is 80°C, the magnesium content must be at least 12.5% to 20°C to meet this temperature.

The most suitable magnesium compound for this purpose is magnesium oxide, which has the highest magnesium content (and is economically inexpensive).

This magnesium oxide is a fine powder and light, so when it is mixed with a solid salt and molded, it has low hardness and easily collapses at °C, and if too much pressure is applied, cracks occur, making compression molding difficult.

As a result of various studies on this point, the present inventor succeeded in molding by adding magnesium chloride and the like.

Further, as a result of developing this idea and investigating various methods of molding without using a hydraulic press, we noticed that magnesium oxide forms a special double salt with an inorganic acid or its salts, or an organic acid or its salts. did.

That is, taking hydrochloric acid as an example, the hydrochloric acid reacts with magnesium oxide as described below to form a double salt.

Therefore, when making this double salt, they simultaneously mixed common salt in the proportions of the seeds and succeeded in obtaining a molded solid salt for livestock.

Furthermore, we investigated a method for manufacturing a solid salt that maintains disintegrability in water with an appropriate hardness or strength difference as a magnesium solid salt for livestock.By adding magnesium carbonate as a binding and softening agent, we have developed a magnesium-containing solid salt for livestock. I was able to make it.

In addition, it is formed by adding a mixture of minerals and other nutrients to common salt or common salt, and an inorganic acid, an inorganic acid salt, an organic acid, and an organic acid salt that react with magnesium oxide to form a double salt.

Solid salts containing magnesium salts are so hard that depending on the minerals or nutritional supplements they are mixed with, even if they are licked by livestock, they may not decrease in quantity and the amount of intake cannot be ensured.

For this reason, it is necessary to soften the food to a certain degree to make it easier to eat, and the carbonate added for this purpose is called a softener.

When these molded products were allowed to be licked freely by cows in pasture, they were effective in preventing and treating grass tetani disease.

The present invention relates to a magnesium solid salt for livestock that has been completed based on the above research results.

The additive substance used in the present invention may be any substance as long as it reacts with magnesium oxide to form a double salt. Therefore, in addition to the above-mentioned hydrochloric acid, inorganic acids such as sulfuric acid, phosphoric acid, and nitric acid, or salts thereof, or are acetic acid, propionic acid, butyric acid, co...
Examples include organic acids such as phosphoric acid, and salts thereof.

Carbonates such as agnesium carbonate and lime carbonate are effective as softening agents.

In addition, common salt can be made plain or with the addition of salt minerals, vitamins, and other nutritional supplements, and can be molded at ℃, making it possible to produce a wide variety of solid salts for livestock depending on the diseases of the livestock.

When producing the magnesium solid salt for livestock of the present invention as described above, compared to the production method using a press, the equipment cost other than adding the required amount of water to form a double salt is less. It has the advantage of being extremely economical and can be manufactured in a confined space, and can be molded into large, medium, and small sizes, and the solid salt obtained is highly effective in preventing and treating grass tetani disease. demonstrate.

Furthermore, according to the solid salt of the present invention, it is not affected by rainwater etc. and can be used for a long time (
Since it can maintain its solid state, it is extremely convenient to place it on pasture and feed it freely to livestock.
