BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feed additive for poultry, and more specifically, it is characterized by using vermiculite weathered with mica-based minerals and a specific acidic solution as main components. The present invention relates to a new feed additive for poultry, which is capable of suppressing morbidity, promoting growth, improving health condition, improving egg laying rate, and improving quality of eggs such as nutrition and physical properties.

[0002]

2. Description of the Related Art Generally, most recent poultry raising methods adopt a three-dimensional cage method. This method is extremely excellent in terms of labor saving and energy saving, because this method can be used as the first method for poultry breeding, the feeding, water supply, egg collection, etc. can be centrally managed, and chicken dung can be easily cleaned. This is because the method is highly profitable. However, with this method, chickens walk around the ground like the flat-bed method, and under the conditions close to nature, there is no opportunity to pluck soil and grass, which is an unhealthy environment for chickens. I can say. Therefore, various problems have occurred in terms of growth, morbidity of eggs and quality of eggs.

[0003]

The above-mentioned problems include, for example, illness, chronic diarrhea, poultry pricking of friend chickens, a decrease in egg laying rate, and deterioration in nutritional and physical properties of eggs. The present invention aims to provide a poultry feed for solving the above-mentioned problems, promoting the growth of chickens, further improving the egg laying rate, and improving quality such as egg nutrition and physical properties. To do.

[0004]

In order to solve the above problems, the present invention provides a poultry feed additive by impregnating vermiculite powder weathered with mica-based minerals with a mineral-containing solution derived from mica-based minerals. To do. Also,
In the present invention, as the mineral-containing solution derived from the mica-based mineral, obtained by dissolving vermiculite in an aqueous solution of mineral acid, an acidic solution containing various metal salts and non-metal salts as main components (hereinafter referred to as an acidic mineral solution and It is particularly desirable to use (as to the acidic mineral solution will be described in detail later).

The vermiculite used in the present invention is a weathered body of mica-based minerals such as granite, and is collected from the soil in each region. In the present invention, the vermiculite in which the mica-based mineral is weathered is used, but if necessary, crushed to an appropriate size is preferably used. Further, a mica-containing mineral-derived mineral solution is a solution containing mica, a rock containing mica, or a weathered humus, such as humus granite or vermiculite, produced by various methods, and containing a high concentration of minerals. Is. In the present invention, as the mineral-containing solution derived from the mica-based mineral, it is particularly desirable to use an acidic mineral solution produced by the following method.

The acidic mineral solution is obtained by using a mica-based mineral, for example, vermiculite which is a weathered body of granite, pretreating it if necessary, reacting it with a mineral acid, and further separating it. is there. In addition, the pretreatment of vermiculite is adopted as necessary in order to allow the mineral acid to act efficiently, and is performed, for example, by pulverizing weathered soil of granite containing vermiculite into an appropriate size. The treatment with mineral acid after the pretreatment may be carried out by allowing the mineral acid aqueous solution to act on the weathered soil of granite containing vermiculite.
The mineral acid is not particularly limited as long as it has low toxicity to living organisms, but sulfuric acid is most preferable. Mineral acid treatment is preferably carried out under heating temperature if necessary,
Continue until the required minerals elute from the vermiculite. Further, after the above-mentioned mineral acid treatment, solid-liquid separation is performed to separate a liquid material and a solid material. As the solid-liquid separation means, for example, a filter press or the like is used, and an acidic mineral aqueous solution having a good ability to generate OH radicals in water and having an action of oxidizing organic substances and inorganic substances is collected.

The properties of the acidic mineral aqueous solution thus separated are as follows. 1. Mineral content: 20% of mineral content in terms of salt
Including the above. 2. Mineral content breakdown: (1) Contains a large amount of aluminum, iron, magnesium, and potassium. (2) Contain most of phosphorus, titanium, calcium, manganese, sodium, silicon, cobalt, lithium, copper, nickel, zinc, and barium. (3) Does not contain arsenic, lead, mercury, or chromium. 3. Specific gravity: 1.1 to 1.5 4. pH: 0.1-2.0

The feed additive for poultry of the present invention is produced, for example, by adding an acidic mineral solution diluted with water to vermiculite having a diameter of 5 mm or less and thoroughly mixing. At this time, the mixing ratio of the vermiculite and the acidic mineral solution is not particularly limited, but considering the physical properties as a feed additive (for example, wettability) and the feeding property of chickens, the dilution ratio of the acidic mineral solution. Is 100 to 10,
000 times, it is desirable to adjust the ratio of the vermiculite to the diluted solution of the acidic mineral solution in the range of 10: 1 to 1:10.

The feed additive for poultry according to the present invention is added to a compound feed for poultry, but it can be applied at both the feed production plant and the poultry site, and is not particularly limited. . Also, the addition amount is not particularly limited, and the feeding characteristics of breeding chickens and differences in age and spawning period,
Alternatively, it may be adjusted according to the blending ratio of the feed additive, etc., but it is preferably in the range of 0.5 to 10% with respect to the feed.

By ingesting the feed additive for poultry of the present invention,
As shown in Examples below, various effects are observed, but the mechanism of action is not always clear. However, one thing that can be inferred is that various types of minerals contained in vermiculite and acidic mineral solutions are acting. Mineral requirements in poultry are well known in the art, and major minerals such as calcium, phosphorus and sodium and manganese,
Mineral requirements for trace minerals such as zinc, iron, copper, iodine and selenium at each spawning season have been announced as numerical values.
And, based on this figure, the mineral-enriched poultry feed that is likely to be in short supply is also used. However, these are limited types of minerals.
The poultry feed additive of the present invention contains various kinds and a large amount. It is considered that these various kinds of minerals synergistically affect the growth of chickens, spawning, etc., and bring about various effects. In other words, from the viewpoint of feed science, it is estimated that chickens have necessary minerals in addition to the currently recognized minerals.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail based on the following examples, but the invention is not intended to be limited thereto. Preparation of poultry feed additive Vermiculite having a diameter of about 3 mm and Seamarox (registered trademark) marketed by the present applicants as an acidic mineral solution diluted 1000 times with well water were mixed with 3 kg: 1 liter. The feed additive for poultry of the present invention (hereinafter referred to as the feed additive of the present invention) was prepared by mixing well in a ratio.
