Description

[Detailed description of the invention]

The present invention relates to a method of eutrophicating millet husks, which have no value as feed as is, and turning them into feed with good feed efficiency. Millet husk is a by-product when manufacturing shelled millet for small bird feed, and has the components shown in Table 1, but it has no other uses and is only used as an auxiliary fuel. It was too much.

[Table] As a result of intensive research into the effective use of millet husks as feed, the present inventors have cultivated edible mushroom mycelia in a culture medium prepared using millet husks as the main material, and have cultivated them either as they are or when fully ripened. The present invention was completed based on the discovery that an excellent feed can be obtained by drying the culture medium after culturing and harvesting the fruiting bodies (mushrooms). That is, the first invention involves inoculating edible mushroom mycelia into a culture medium prepared using millet husks as a main material and culturing them, adding conventional feed additives as necessary, and drying to produce feed. It is characterized by:
The second invention involves inoculating and culturing edible mushroom mycelia into a culture medium prepared using millet husks as the main material, cultivating and harvesting edible mushrooms, adding conventional feed additives as needed, and drying. It is characterized by being used as feed. The culture medium in the present invention is prepared using millet husks as a main material, and can be prepared according to conventionally known methods. For example, millet husks are mixed with nutritional sources such as rice bran and bran, and if necessary, fibrous additives such as corn culm, which can be used as roughage, are added to contain an appropriate amount of moisture110
It can be prepared according to a method of heat sterilization at a temperature in the range of ~125°C. At this time, the amount of millet husk used is 15 to 40% by weight of the entire culture medium, preferably 17 to 40% by weight.
The amount is in the range of 32% by weight. There are no particular restrictions regarding the cultivation of edible mushroom mycelium and the growth of fruiting bodies (mushrooms). Enoki mushroom,
This can be carried out by inoculating the inoculum of edible mushrooms such as shiitake, wood ear fungus, nameko mushroom, etc., culturing in a culture room maintained under appropriate conditions, allowing the mushrooms to ripen, and then scraping the fungi to grow fruiting bodies. In the present invention, the culture medium is inoculated with edible mushroom mycelium, cultured, and then dried and powdered. Alternatively, the culture medium is dried and powdered after growing fruiting bodies (mushrooms) and harvesting them. The resulting product is used as feed. At this time, amino acids, vitamins,
Conventional feed additives such as minerals and the like can be included. Further, there are no particular restrictions on the drying conditions, and it is preferable to use hot air in the range of 80 to 150°C, for example. The feed thus obtained has high nutritional value and good feed efficiency, and is extremely excellent as animal feed. It is surprising that according to the present invention, millet husks, which had no conventional use, can be effectively used as feed, but this is probably due to the following reasons. That is, it is thought to be based on the reason that heat sterilization is performed when preparing a culture medium, and as a result, components such as cellulose in millet husks that are difficult to digest and absorb by animals as they are are decomposed and become constituents of hyphae. However, the present invention is not limited solely to this reason. Hereinafter, the present invention will be explained in more detail with reference to Examples. Example 1 30 kg of millet husks and 10 kg of rice bran were mixed uniformly, and water was sprinkled on the mixture to adjust the moisture content to 65%. This mixture was divided into 100 heat-resistant wide-mouth bottles with a capacity of 800 c.c., and filled.
After high-pressure steam sterilization at a temperature of 120°C for 2 hours, the mixture was cooled to room temperature to prepare a culture medium. Next, 10 c.c. of oyster mushroom starter was inoculated per plant, and the temperature was increased.
The cells were cultured for 18 days in a room maintained at 24°C and 60% humidity.
After this, the culture medium in which the oyster mushroom fungus was cultured was taken out from the bottle, dried in a high-temperature dryer at 80°C or higher until the moisture content was 15% or less, and ground into feed. The composition of the feed obtained in this way was 14% crude protein;
It contained 4% crude fat, 40% soluble nitrogen-free substances, and 14% moisture, making it effective as feed for cattle, pigs, and poultry. Example 2 Culture was carried out in the same manner as in Example 1 for 18 days. After culturing to full maturity for another 4 days, the bacteria were scraped,
Fruiting bodies were grown for 15 days in a room maintained at a temperature of 13-16°C and a humidity of 80-95%, and then harvested. Thereafter, the culture medium was removed from the bottle and feed was obtained according to the same procedure as in Example 1. Feed composition is crude protein 12
%, crude fat 3%, soluble nitrogen-free matter 40%, water 14%
It was hot. Example 3 As an experimental group, approximately 8-month-old dairy cows were fed a total weight of 10 kg of feed consisting of 1 kg of the feed obtained in Example 1, 2 kg of rice straw, 2 kg of commercially available mixed feed, and 5 kg of green grass per head per day. (Holstein breed, average weight
320Kg) were fed to each of the three animals for two months, and the amount of weight gain during that period was measured. As a result, the average weight gain per animal per day was 0.62 kg. In addition, as a comparison area, per day, per head,
2 kg of rice straw, 3 kg of commercially available mixed feed, and 5 kg of green grass
Three dairy cows (Holstein breed, average weight 310 kg), approximately 8 months old, were each fed a feed containing 10 kg in total weight for 2 months, and their weight gain during that time was measured. As a result, the average weight gain per animal per day was 0.57.
It was Kg. As described above, it was confirmed that the feed of the present invention is suitable for use as a eutrophic feed because cows who would not eat millet husk as it is eat the feed of the present invention and have good weight gain and good digestion.
