Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a method for producing a feed using a waste medium of mushrooms.

[Prior art and problems]

Conventionally, a method of producing a feed from a mushroom medium (waste medium) after cultivating a mushroom has been proposed, for example, in JP-A-51-22581, a feed is produced from a culture medium after cultivating an edible mushroom. A method of doing so is disclosed.

According to the method for producing a feed disclosed in the publication, a culture medium containing okara as a main component after heating edible mushrooms is heated and dried to a water content of about 30% by weight, and a substance effective as a feed component is added. It is added as needed and used as feed.

However, the feed obtained by such a conventional production method cannot be expected to be effective in promoting the growth of livestock such as the meat quality of the livestock being softened, although it forms the body of the feed.
The fact is that it is insufficient as feed. For example, even if they are actually fed to chickens and pigs, they do not like to eat them, and there is a problem in terms of taste, and the mushroom mycelia remaining in the waste medium are difficult to digest and absorb in the body of livestock. There was a problem that impeded growth and health promotion.

It is an object of the present invention to provide a method for producing a feed that solves the problems existing in the conventional art.

[Outline of Invention]

The method for producing a feed according to the present invention is a waste medium after cultivating a mushroom medium mushroom containing at least corncob, adding an organic acid-producing bacterium such as a lactic acid bacterium that decomposes mycelia in the waste medium by fermentation, Temperature (for example, approximately 36-40
(° C) and leave it for a predetermined time (for example, about 1 day) to ferment it, and because of the organic acid produced by the organic acid-producing bacteria, the specified PH on the acidic side where no bacteria propagate
The value is set and the waste medium after this is directly used as feed.

As a result, the organic acid-producing bacterium (lactic acid bacterium) decomposes the mycelium in the waste medium by fermentation to produce an amino acid that is easily digested and absorbed, improves palatability, and prevents spoilage of the wet feed.

〔The invention's effect〕

The feed produced in this way has the following effects.

By improving palatability, the appetite of livestock can be increased and digestion becomes extremely good. Therefore, especially in the case of chickens, (a) promotion of growth of the chickens themselves, (b) large eggs and at least after initiation of spawning Remains above 90% of average spawning rate for about 2 months (see drawing), (c) Chicken wings almost never fall out, (d) No barking, etc. Make a difference. Also, in the case of pigs, the average weight increases by about 40% compared to conventional pigs,
Moreover, it was confirmed that it did not become soft fat.

Animal dung has no odor, does not cause offensive odor pollution,
It can be used as a superior organic fertilizer either directly or by mixing it with compost.

Although it is a wet feed, it can be stored for a long period of time and does not rot for more than 3 months even at room temperature in summer. In addition, since a drying step and the like are unnecessary, it can be easily manufactured at low cost.

〔Example〕

Next, a preferred embodiment according to the present invention will be described in detail.

First, as the components of the mushroom medium, the compositions shown in Table 1 or Table 2 are suitable.

Organic mushrooms and water are added to the medium composition shown in each table, and the mixture is stirred, and finally adjusted to a water content of about 65% and a pH of about 4.0 to prepare a mushroom medium.

Then, this medium is put into a cultivation bottle, and mushrooms are cultivated based on a normal mushroom cultivation process.

The mushroom medium (waste medium) that has been harvested is scraped from the cultivation bottle and crushed, and other components are newly added in accordance with the mixing ratio shown in Table 3 from the viewpoint of the balance of nutrient sources.

Liquid lactic acid bacteria (fermenting bacteria), which are organic acid-producing bacteria, are further added to the feed base thus formulated. The method of addition is, for example, spraying and stirring well. And about one day (one day and night) in the atmosphere of temperature 36-40 ℃
Leave to ferment. As a result, PH is around 4.8,
Obtain a good quality moist feed that does not propagate bacteria.

The obtained moist feed was given to each of 10 experimental chickens (experimental group) 5 g twice a day, and the data in the following table were obtained. In order to confirm the effect of the moist feed according to the present invention, lactic acid (organic acid) was directly added without fermenting the waste medium after cultivating mushrooms, and a comparative feed prepared by adjusting PH to around 4.8, The other 10 experimental chickens (control group) were considered under the same conditions as the experimental group.

Thus, when the "chicken weight" and "egg size" of the experimental plot and the control plot were compared, superior results were obtained in all of the experimental plots. In addition, the chickens in the experimental area were also found to have “feather loss”, “smelling chicken droppings” and “calling”.
The result was superior to the control chicken and the number of diseased chickens was 0.

By the way, it is known that when organic acids such as lactic acid are added to the feed, the palatability is enhanced, the growth of livestock is promoted and the spawning rate is increased. In terms of "chicken weight" and "egg size", which were directly related to, the results were far superior to those of the control group. In addition, the moist feed in the experimental section is not only highly palatable, but the waste medium is fermented by lactic acid bacteria (organic acid-producing bacteria) and decomposed into amino acids with extremely high digestibility and absorption. Problems such as liver damage disappeared, the physical condition and disease resistance of chickens were improved, and many improvements were confirmed in aspects other than growth promotion, such as "feather removal", "chicken dung odor", and "calling". .

In addition, from the balance of palatability and nutritional sources, molasses, beet pulp, bacchus, apple juice squeeze produced in the sugar manufacturing process, fish meal as a protein source, etc. are selected and mixed as necessary, and seasoned. You may.

As the mushroom fungus to be cultured, mushroom fungi, shimeji mushrooms, nameko mushrooms, hiratake mushrooms, and various other mushroom fungi can be applied.
