Description

Feed additive based on calcined diatomaceous earth

The present invention relates to the use of calcined diatomaceous earth as feed additive in the intestines of animals having very high adsorption power of harmful gases or toxins.

Recently, with the development of the livestock industry, there has been a growing interest in the removal of odors and intestinal toxins caused by animal feces. Adsorbent minerals such as zeolite, bentonite, activated carbon and the like are known as inorganic adsorbents and generally used for the purpose of water purification and deodorization. In particular, zeolite or activated carbon has been mainly used for the purpose of absorbing the intestinal gas of livestock.

Conventional deodorizers have been used by powdering by treating two or more minerals such as bentonite, peat (corrosive soil) physically or chemically, but these were scattered during use and contaminated the surroundings. In addition, calcined lime and gypsum chloride may be used as the deodorizing agent by adding an oxidation promoter thereto, but this has the disadvantage that its use is extremely limited.

On the other hand, Japanese Patent Publication No. 55-47143 provides a method for producing ammonia deodorant by breaking zeolite in sulfuric acid, immersing it in an aqueous solution of ferrous salt after washing, and drying it, but absorbing other harmful gases other than NH ₃ gas. There is a drawback to not doing it.

The present invention removes harmful gases such as trimethylamine, ammonia, hydrogen sulfide and nitrogen gas generated in the intestines of animals in consideration of the disadvantages of the general deodorant and animal feed additives, and prevents the stool smell as well as effectively prevents fecal odor. It is an object of the present invention to provide a feed additive for removing intestinal harmful gases and toxins of livestock to be removed.

In order to achieve the above object, the present invention is a natural mineral diatomaceous earth (Diatomaceous Earth) is calcined to prepare a porous inorganic adsorbent and using it to investigate the adsorption capacity of harmful gases and water was completed through on-site clinical experiments. Hereinafter, the specific configuration and operation of the present invention will be described with reference to Examples, but the scope of the present invention is not limited only to these Examples.

Diatomaceous earth is the accumulation of harmful substances of plants called diatoms that grow in freshwater or seawater. It is composed of extremely small single-cell diatoms and its size is about 5μ ~ 400μ, and there are countless pores (1μ ~ 10μ) in the diatom. The pores are very light and have a large surface area. Therefore, generally, the structured soil has a strong hygroscopic action by physical capillary condensation by pores, and this absorbing power is more powerful than the hygroscopic or deodorizing mechanism of silica gel by hydrogen bonding exposed to the surface by silanol (Si-OH). . Hereinafter, the concrete action of the calcined diatomaceous earth of the present invention is presented as an experimental result.

Example 1

Manufacture of Plastic Structural Soil

The natural diatomaceous earth of Donghae Ansan was crushed to 3mm-7mm size, washed and dehydrated, and fired until discolored red at 500-1000 ℃. The calcined diatomaceous earth was allowed to cool and then impregnated with CaCO ₃ 30% aqueous solution for about 30 minutes, and then dehydrated again to be activated at 300 to 350 ° C. to prepare a porous inorganic adsorbent.

Example 2

Hazardous Gas Adsorption Test

In order to examine the harmful gas removal effect of the calcined diatomaceous earth of the present invention prepared in Example 1, ammonia, trimethylamine, hydrogen emulsion, methyl mercaptan as a test material, and 20% of the active ingredient as a standard solution ( Using propylene glycol solution of w / w), each harmful gas is used as a standard solution of 1g in a 10-liter sealed container, and the harmful gas remaining in the container is determined by acid or alkali titration method every 1, 5, 10, or 20 minutes. It was.

The experimental results are shown in Table 1.

TABLE 1

As shown in Table 1, it was confirmed that there is an effective deodorizing effect on all harmful gases.

Example 3

Moisture adsorption capacity investigation

In order to test the water adsorption capacity of the calcined diatomaceous earth of the present invention prepared in Example 1, the calcined diatomaceous earth granules were put into a drier adjusted with sulfuric acid solution at a relative humidity of 30%, 60%, and 90% to change the time-dependent change of the water adsorption amount, respectively. The survey results are shown in Table 2 below. As a control, silica gel was used.

TABLE 2

Experimental results As shown in Table 2, it was confirmed that the water adsorption capacity was improved by about 30 to 60% than that of the control silica gel.

Example 4

Field breeding experiment

The results of the on-site breeding experiments of the calcined diatomaceous earth of the present invention prepared in Example 1 to the laying hens, broilers, pigs, and cows by adding 0.03-0.5 kg of feed per ton are shown in Table 3. The control group was administered with only photosynthetic bacterium (PTB-plus) to the rich feed, and the experimental group was added to 0.05% of the present invention to the experiment.

TABLE 3

As a result of the specification test of the present invention calcined diatomaceous earth, the spawning rate, weight gain and feed efficiency were significantly increased as shown in Table 3, fecal odor was significantly reduced and fecal quantity was also reduced.

As confirmed through the above experiments and examples, the calcined diatomaceous earth of the present invention is a very useful invention for livestock and feed industry because it has an excellent effect as a feed additive for removing intestinal harmful gases and toxins.
