DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to tables and drawings showing embodiments.

The feed additive of the present invention is added, for example, to a feed for fish and shellfish such as Thai, yellowtail and shrimp to be cultured, so that the fish and shellfish can be bred healthy and the fish and shellfish can grow (cultivation). In order to keep the environment in good condition (such as a pond), the mixing ratio of the first embodiment is shown in Table 1. In the present invention, fish and shellfish are not limited to those that inhabit in seawater, but include fish and shellfish that inhabit freshwater and brackish water.

[0011]

[Table 1]

The feed additives shown in Table 1 are adapted to fish and shellfishes in general, and contain by-products of animal foods, residues of vegetable foods, residues of seaweed foods, and various minerals. A sedimentary layer, a plant containing an antioxidant, charcoal, and a microorganism are mixed at a predetermined ratio and fermented. Specifically, 10 ~
70% by weight, 10-60% by weight of vegetable food residue, 3-30% by weight of seaweed food residue, 1-20% by weight of sedimentary layer containing various minerals, 0.1% of plant containing antioxidant ~ 5
% By weight, charcoal 0.5-10% by weight, microorganisms 0.0001-0.00
It is fermented and produced at a setting of 05% by weight. In addition,
In the present invention, charcoal is defined to include processed charcoal. For example, it is also preferable to use a charcoal surface made of ceramic to make the surface more porous (“Ceramic Charcoal” manufactured by Kazan Ryoku Co., Ltd.).

[0013] Here, by-products of animal foods include unwanted meat pieces, residues of internal organs and blood, etc. remaining after slaughtering livestock such as cows, pigs and chickens, and heads, internal organs and blood of fish and shellfish. It is a residue. In addition, the residue of vegetable foods, such as tofu snowy greens, oil cake,
Vegetable waste, cereal meal, etc.
It is debris such as Honda straw, blue seaweed, seaweed, seaweed and kelp. In the present invention, wastes from these food processing (by-products of animal foods, residues of vegetable foods, and residues of seaweed foods) are used as main raw materials, and are intended for resource saving, recycling, and environmental conservation.

In the feed additive of the present invention, the by-products of animal foods mainly supplement animal proteins, and the residues of vegetable foods mainly supplement vegetable proteins and vitamins. Yes, seaweed food residues prevent disease by mainly supplementing minerals such as iodine and enhancing the immune defense mechanism of the living body. Furthermore, various minerals are supplemented by sedimentary layers such as seabed ridges containing shell fossils to enhance bioregulatory ability, and antioxidants (curcumin, β-carotene, etc.) contained in plants such as turmeric and carrots (especially turmeric) Is added for the purpose of eliminating various active oxygens and active lipids generated in a living body. In addition, charcoal characterized by porous is to prepare the environment where microorganisms live,
Fermentation of these mixtures by microorganisms (multiple types of Bacillus subtilis) into absorption-type nutrients increases the efficiency (growth, weight gain and disease resistance) of fish and shellfish and improves their health To ensure that fresh seafood grows.

By the way, in conventional aquaculture, there is a problem that about 40% of the fish die in a state where fish are densely packed in a cage. The cause is that fish droppings and food left behind are deposited and deposited in the cage and become sludge, which deteriorates the environment of the cage and reduces the immunity of fish due to active oxygen generated from mitochondria, causing viruses and bacteria. It has been considered that the susceptibility to infection and the like, a decrease in liver function of surviving fish, and an increase in bad cholesterol are problems.

[0016] The feed additive of the present invention is used by adding it to the feed at a predetermined ratio according to the type of fish and shellfish to be cultured. By feeding the feed to which the feed additive has been added, the mortality rate of the cultured fish and shellfish is reduced, and the fish and shellfish grow healthy (by increasing the good cholesterol). That is, the growth of hormones is promoted by minerals such as iodine and the slimming of fish and shellfish (especially fish) is increased, whereby the physical immune defense mechanism of fish and shellfish is enhanced and the growth and disease resistance are improved. In addition, antioxidants (curcumin and β-carotene) can eliminate various active oxygens that reduce the in vivo immunity of fish and shellfish, thereby enhancing the immunity of fish and shellfish. In other words, it can be said that the feed additive is a viable bacterial preparation that acts beneficially in the body of the fish and shellfish ingested.

Further, the floating rate of fish and shellfish dung is increased, and the dung is diffused outside the cage, that is, it is difficult for the dung to settle at the bottom of the cage, and the feed left behind by the fish and shellfish is also reduced. Even if some feces settle on the bottom of the cage, they are decomposed in a short time by various Bacillus subtilis in the feed additive, so that the inside of the cage is purified and a favorable environment for the growth of fish and shellfish is maintained.

Next, Table 2 shows the mixing ratio of a feed additive (second embodiment) that is most suitable for crustaceans such as shrimp and crab among the fish and shellfish to be cultured.
