Description

  The present invention relates to a livestock feed used for livestock such as cattle, horses, pigs, sheep, and ostriches, or an aquaculture feed used for cultured seafood, and more specifically, ferment a mixture of useful microorganisms in okara. Thus, the present invention relates to livestock feed or aquaculture feed provided with a function of increasing functional fatty acids contained in fat of livestock or cultured seafood and a function of lowering cholesterol in fat.

  Mixed feed is mainly used as livestock feed, but agricultural chemicals are often used in large quantities in order to increase the yield of the raw material of the mixed feed. Japan relies mainly on imports of livestock feed. As a result of the use of disinfectants and preservatives to increase the long-term storage stability of livestock feed, chemical substances remain in the livestock feed and cause health damage to the livestock. It is known that the digestion and absorption rate is deteriorated due to inhibition. In addition, antibiotics are used to prevent disease damage.

A large amount of organic waste, Okara, is generated as a by-product when producing tofu and soymilk. Okara has high nutritional value and can be used as food and feed, but has a high moisture content and extremely poor storage stability. Therefore, it is known to add a lactic acid bacterium to okara to make a livestock feed that can be stored for a long period of time and has an intestinal regulating action such as probiotics.

As shown in Japanese Patent No. 3710424, the present inventor mixed an effective waste group consisting of 55% aerobic bacteria group and 45% anaerobic bacteria group into organic waste to mix 40-200. Primary fermentation is carried out at a temperature of 24 ° C. for 24 hours, and further, an effective microorganism group consisting of 55% aerobic bacteria group and 45% anaerobic bacteria group is mixed with this, and this is mixed with the object to be processed in 100 to Decomposing heavy metals, dioxins and pesticides characterized by decomposing heavy metals, dioxins or pesticides contained in the material to be treated by secondary fermentation at a temperature of 200 ° C. for 24 to 48 hours A method (hereinafter referred to as “method for decomposing heavy metals, dioxins and agricultural chemicals by the present inventor”) is provided.

(3) Cholesterol concentration contained in fat is suppressed to obtain good quality meat and lipid (claim 3).

  According to the present invention, it is possible to obtain livestock feed or aquaculture feed that is highly safe and inexpensive. That is, the livestock feed or aquaculture feed according to the present invention is a safe product in which heavy metals, dioxins and agricultural chemicals are decomposed. In addition, the livestock feed or aquaculture feed according to the present invention is extremely inexpensive because it uses organic waste Okara as a raw material.

  The livestock feed or aquaculture feed according to the present invention is mixed with a useful microorganism group consisting of 55% aerobic bacteria group and 45% anaerobic bacteria group in okara at a temperature of 40 to 200 ° C. First time fermentation is performed, and a useful microbial group consisting of 55% aerobic bacterial group and 45% anaerobic bacterial group is mixed into this, and the mixture is mixed at a temperature of 100 to 200 ° C. for 24 to 48 hours. By carrying out the second fermentation, it is preferable to have the functionality of increasing the functional fatty acid contained in the fat of livestock or cultured seafood and the function of lowering the cholesterol of the fat.

  In the present invention, a useful microorganism group is used in which the proportion of the number of mixed bacteria is about 55% aerobic bacteria group and about 45% anaerobic bacteria group.

The effective microbial population includes:
Yeast, cellulose-degrading bacteria, nitrogen-fixing bacteria, lactic acid bacteria, filamentous fungi (aromatic compound-degrading bacteria), manganese-reducing bacteria (black mold genus group-protozoan basidiomycetes), manganese-oxidizing bacteria (organic vegetative bacteria), ammonia-oxidizing bacteria (sublimation) Nitrate bacteria), actinomycetes (chitin-degrading bacteria), nitrate bacteria (nitrifying bacteria), sulfur bacteria (bacteria group using hydrogen sulfide as a hydrogen donor), methane oxidizing bacteria, cellulose actinomycetes, cellulose filamentous fungi, natto bacteria , Lignin-degrading bacteria, iron-oxidizing bacteria, iron-reducing bacteria, sulfate-reducing bacteria, acetic acid bacteria, Bacillus sp., Sporosarcina sp., Paenibacillus sp., Oceanobacillus (Oceanobacillus) sp.).

The effective microorganism group is mixed in okara and subjected to primary fermentation at a temperature of about 40 to 200 ° C. for about 24 hours.

For example, the effective microorganism group is used at a ratio of 1 kg (wet weight) to 1000 kg (wet weight) of okara.

In addition to Okara, food residues such as coffee beans, tea shells, vegetable scraps, seafood scraps, leftovers, eggshells, beer lees, sake lees, and shochu are used.

In addition to food residues, organic waste such as bark, rice bran, rice bran, and bran is used.

A mixture of useful microorganisms comprising about 55% aerobic bacteria and about 45% anaerobic bacteria is further mixed into the product obtained by primary fermentation as described above (floor material). Secondary fermentation is performed at a temperature of 200 ° C. for about 24 to 48 hours. The flooring is used for moisture adjustment.
