Description of the Related Art Conventionally, as feed for livestock, the cost of feed has been reduced by using advanced feed of weeds, completely converting sawdust, chicken waste, straw, etc., and converting vegetable residues and waste into feed. In addition, storage of feed by changing feed components,
Various fermented feeds have been proposed and used in order to enhance flavor and the like.

In particular, rice bran, which is often used in feeds, has a high fat content and energy content, and has excellent palatability for livestock, etc. The livestock may then have diarrhea. Further, a large amount of organic phosphorus is contained as an inorganic substance, and when used in a large amount as it is, urolithiasis is caused, so that much cannot be supplied.

As a result, it is possible to improve meat quality such as increasing the degree of marbling (sashi), improving the meat color, texture and shrinkage, and reducing the subcutaneous fat. Also, as described above, it is generally said that feeding a phosphorus-rich feed at the end of fattening causes urolithiasis and diarrhea, but feeding the feed of the present invention does not have such a problem.
