Description

Feed additive for cultured fish and its manufacturing method {Feed additive for cultured fish and method for manufacturing the same}

The present invention relates to a feed additive for aquaculture fish and a method for producing the same. Specifically, the present invention is fermentation and fermentation at a constant temperature and for a certain period of time using turmeric powder, red grape concentrate, molasses and EM microorganism as main additives to prepare a liquid solution, and mix well within 1% of the total feed amount of fish farmed fish. The present invention relates to a feed additive for farmed fish and a method for producing the same, which promote the digestion and absorption of nutrients by enzymes contained in the feed additive to improve the productivity of fish farming.

The growth of aquatic animals depends on the quality and quantity of feed, but fish farming requires the most efficient breeding of a large number of fish in a limited body of water.

In recent years, the production of aquaculture fish has increased rapidly. However, as the consumption of feed is increased and the study of compounded feed is delayed, techniques for using feed effectively are being examined.

The protein source of conventional aquaculture fish feed mainly depends on animal protein resources, but there is a certain limit on the amount of resources. In the long term, the search for new protein resources is necessary, but as a matter of course, it is a study on how to effectively use the protein resources currently used as feed.

Fish meal, which is mainly used as an animal protein raw material for aquaculture fish, has little difference in the growth level of aquaculture fish when compared with acid food, although there is almost no difference in the nutritional composition of the fish. The point is pointed out. This is because the digestibility, ie, the rate at which feed is digested and absorbed by meat, is low.

Therefore, improvement of digestibility is related to the effective use of protein resources. In addition, in order for the protein to be used more as a growth promoting factor, which is its original purpose, it is important to efficiently use fat as an energy source.

Attempts to improve digestibility of nutrients by adding digestive enzymes to aquaculture feeds have been made since the 1960s, and although some effects are recognized, technology development is required again in practical use.

Therefore, the present inventors have come to develop a feed additive for farmed fish to improve the productivity of fish farming by promoting the digestion and absorption of the nutrients contained in the feed additive to solve the above problems.

In the present invention, various raw materials including turmeric, molasses, water, and EM (Effective Microorganisms) microorganisms are put into a fermentor, and fermented at 55 to 65 ° C. for 24 hours, and then the temperature is lowered to 35 to 40 ° C. and fermented again for 72 hours. It is to provide a feed additive for farmed fish to improve the meat quality and taste of the farmed fish eaten in a container when it is less than 4.0 and made into small grain-type feed and distributed to the farmed fish.

Another object of the present invention is to facilitate the excretion of sperm and yolk by smoothing the intestinal and reproductive tract of fish by adding turmeric and selenium to the feed.

Another object of the present invention is to promote the digestion and absorption of nutrients by enzymes contained in the feed to improve the productivity of fish farming.

The above and other objects of the present invention can be achieved by the present invention described below.

The feed additive for aquaculture fish according to the present invention is prepared by stirring and fermenting molasses and red grape concentrate, vitamins A, D3, E, and C raw materials, selenium, water, EM microorganism and turmeric powder to prepare an additive of a liquid solution, Powder: 3,000g, Red Grape Concentrate: 3,000g, Vitamin A: 5,000,000IU, Vitamin D3: 500,000 IU, Vitamin E: 3,000mg, Vitamin C: 10,000mg, Selenium: 100mg, Water: 100ℓ EM Microorganism: 1,000㏄ Molasses : It is characterized by 1,000g.

In addition, the present invention the feed additive manufacturing method for the abbreviation,

3,000 g of turmeric powder, 3,000 g of red grape concentrate, 5,000,000 IU of vitamin A, 500,000 IU of vitamin D3, 3,000 mg of vitamin E, 10,000 mg of vitamin C, 100 mg of selenium, 1,000 g of molasses, 1,000 g of EM microorganism and 100 l of water Stirring to make a liquid solution by mixing;

A primary fermentation step of putting the stirred solution into a fermentor having a temperature of 55 to 65 ° C. for 24 hours;

A secondary fermentation step of fermenting the first fermented solution at a temperature of 35 to 40 ° C. for 72 hours;

When the oxygen concentration in the liquid fermented sufficiently for 72 hours to specify a pH of 4.0 or less, it is characterized in that it is used to mix in 1% of the total amount of feed in a container.

The present invention fermentation and fermentation at a constant temperature and for a certain period of time using turmeric powder, red grape concentrate and molasses and EM microorganisms as a main additive, to prepare a liquid solution to mix well within the range of 1% of the total feed to feed fish In this way, the enzymes contained in feed additives promote the digestion and absorption of nutrients, thereby improving the productivity of fish farming.

Example

Composition of Feed Additives

Turmeric powder: 3,000g,

Red grape concentrate: 3,000 g,

Vitamin A: 5,000,000 IU,

Vitamin D3: 500,000 IU,

Vitamin E: 3,000 mg,

Vitamin C: 10,000 mg,

Selenium: 100 mg,

Water: 100ℓ

EM microorganism: 1,000㏄

Molasses: 1,000 g

The turmeric, that is, the turmeric root of Curcuma longa Linne (畺 黃) as it is or the bark is removed and dried to make powdered powder.

The pharmacological action of turmeric promotes excretion, reduces the formation of semicarcinomas in the coronary arteries, thereby smoothing the intestinal and reproductive tracts of fish to improve productivity and improve meat quality.

The red grape uses a concentrate, helps digestion of fish farming, and can reduce the absorption of sodium, which weakens bones.

The selenium is a mineral (trace element) nutrient, which is an important component of antioxidant enzymes that protect cells from free radicals generated during normal oxygen metabolism, and improves the immune system of fish farming.

The EM microorganisms (Effective microorganisms) are yeast, lactic acid bacteria, yeast bacteria, photosynthetic bacteria, etc., and acts as fermentation and oxidation prevention, water purification, and toxic removal of feed.

Therefore, the aquaculture additive provided as described above makes the feed by the following manufacturing method.

Feed additive manufacturing method

Each raw material: 3,000 g of turmeric powder, 3,000 g of red grape concentrate, 5,000,000 IU of vitamin A, 500,000 IU of vitamin D3, 3000 mg of vitamin E, 3000 mg of vitamin C, 100 mg of selenium, 1,000 g of molasses, 1,000 EM of EM microorganisms and 100 ℓ of water Put in a stirrer and mix.

The mixed liquid solution is placed in a fermentor. At this time, the temperature of the fermenter is maintained at 55-65 ° C. and the first fermentation is carried out for 24 hours.

Next, after 24 hours, the temperature was lowered to 35 to 40 ° C., followed by a second fermentation for 72 hours.

Specify the oxygen concentration of the fermented feed sufficiently for 72 hours and place it in a container when the pH is below 4.0.

At this time, to activate the PSB bacteria (photosynthetic bacteria) generated during the fermentation of EM microorganisms to check the ph state to turn on the lamp.
